JINSHENG Spoke AXLE - High-Quality Non-Braking Axle for Versatile Applications

Product Overview

This is a non-braking spoke axle from the JINSHENG Spoke Wheel Hub Series — the axle that runs under trailers and towed equipment where the braking job belongs to the towing vehicle or to a separate brake system on the trailer itself. It carries a rated load from 2.5 tonnes up to 10 tonnes, and a reinforced build is available for 12-tonne work.

Each unit leaves us as a complete beam with both spoke hubs fitted, the spring mounting brackets in place and the spindle ends finish-machined. The hubs are drilled for the 20-inch spider wheel pattern, and the beam is supplied in either of the two diameters we build, depending on the capacity and the configuration you order. Machined journals and stud threads are left clean so bearings and wheel nuts seat properly.

Track length and wheelbase are built to order rather than taken off a shelf. A trailer builder can send a drawing and have the hub faces set to the deck width and the axle centres set to the suspension layout; a workshop replacing a worn unit can take the dimensions off the old axle and have the same geometry back. Every finished axle is checked against the agreed drawing before it is packed.

Steel Grade Selection

Two grades are available, and the difference matters more than the grade name on the drawing. Standard beams are made from 45# steel: a medium-carbon grade that machines cleanly, welds without drama and responds predictably to quenching and tempering. For general freight, utility and agricultural duty it gives a sensible balance of strength and toughness at a workable weight.

Where the trailer works harder, 20CrMnTi is offered as an option. It is an alloy grade with more core strength, which pays off when the axle absorbs repeated shock — rough site roads, potholes at speed, uneven loading across a low deck — and where the buyer wants margin in a build that will be worked for years rather than seasons.

The choice is usually a conversation rather than a calculation. Tell us the gross weight the trailer runs at, the worst road it will see, roughly how many kilometres a year, and whether the load is steady or shock-loaded, and we will say which grade we would put on that build. The grade is agreed with the spoke axle manufacturer before your order enters production, so there is no substitution halfway through. If your own specification already names a grade, we work to it.

- Quenching and tempering, not surface hardening – the beam is heated and quenched, then tempered back, so the treatment runs through the section rather than sitting in a skin that can flake or wear through. - Hardness held at HRC 28–32 – hard enough to resist indentation and wear at the spindle and bearing seats, where a slack fit would show up as wheel runout. - Why there is a ceiling – past this range the steel loses the toughness that lets it flex under a pothole and come back. A harder beam would be a more brittle beam. - Consistency between orders – the same cycle is applied to each production run, so a second axle ordered a year later behaves like the first one on the same trailer. - What it does in service – a treated beam resists taking a permanent set when the trailer is loaded unevenly, and the hub faces stay square to the beam for longer. - What it does not do – it does not raise the rated capacity. A treated 8T beam is still an 8T beam, and the reinforcement option, not the hardness, is the way to carry more.

The beam and hub bodies are finished either by electroplating or by galvanizing, both of which resist corrosion and surface wear. Which one suits a build depends on where the trailer lives. Electroplating gives a clean, even finish that holds up well in dry inland duty and keeps a tidy appearance on a trailer that is washed regularly. Galvanizing is the stronger choice where the axle meets humidity, coastal air, fertilizer or winter road salt — the conditions that turn a small coating scratch into a rust line within a season. Machined journals and the stud threads are kept clear of the finish so that bearings, seals and wheel nuts seat on bare, accurate metal. Those surfaces are protected for transit instead, and the coating is restored on them when the axle is fitted. If a wheel or a lift jack damages the finish during fitting, touch it up with a matching paint before the trailer goes back into service. Small repairs made early are what keep a running-gear assembly looking and lasting like it should. Tell us the working environment when you order and we will confirm which of the two finishes we recommend for that build.

Brake & ABS Configuration

• No brakes, by design – this axle bridge carries the wheel and the load; stopping is handled by the towing vehicle or by a brake system mounted separately on the trailer. Nothing is missing from the unit — the configuration is simply different.
• Where that suits – utility and yard trailers, site trailers that never see highway speed, agricultural and towed machinery, and builds where the brake set is specified and supplied as its own assembly.
• ABS does not apply to this unit – with no brake to modulate and no wheel-speed sensor at the hub, there is nothing for an anti-lock system to control. Fitting ABS hardware to a non-braking axle would add parts without adding function.
• ABS is available in the same series – braked versions of the Spoke Wheel Hub Series can be ordered with an optional ABS system compliant with ECE R13/H, for trailers that need it under local rules or operating conditions.
• If your market requires brakes – say so at the enquiry stage and we will quote the braked variant instead of adapting this one. Retrofitting brakes to a non-braking beam is not a sensible route.
• Keep the choice consistent across the trailer – mix a braked axle and a non-braking axle on the same bogie only when the trailer design deliberately calls for it, and confirm the arrangement with your inspector before ordering.

Wheel & Hub Fitment

The hubs are drilled for 5 or 6 studs at 3/4″, on a P.C.D. of 11.25″ with an H dimension of 9.44″. In plain terms: the stud circle is the bolt pattern your wheel must match, and the H dimension sets how far the wheel sits outboard of the hub face — which in turn decides where the tyre ends up relative to the fender and the trailer frame. The wheel we recommend for this hub is a 20″ × 5 spider hub, and that is the combination most builds are specified around.

Before you order, match the wheel rather than the axle alone. Take the wheel you intend to use, measure the stud circle across opposite studs, confirm the thread is 3/4″ and check the nut seat type — steel wheels and alloy wheels do not always take the same nut. If the wheel is an existing one, a photograph of the hub face with a tape across the studs is usually enough for us to confirm the pattern.

Stud count is the other half of the decision. Five studs and six studs are both available, so order the count your wheel carries rather than the count a similar trailer happens to use. If your existing wheels are 5-stud and the replacement axle is built 6-stud, no amount of torque will make them fit.

Send the wheel specification with the axle drawing. Getting the hub right on paper is the difference between a bolt-on fit and a set of adaptor plates that nobody wants on a working trailer.

Load Rating & Reinforcement

• Rated per axle, not per trailer – the figure on this axle applies to what one axle carries. A tandem trailer running at 16 tonnes shares that weight across two axles, and the rating has to cover the share, not the total.
• Allow for the load position – cargo sitting behind the axles shifts weight onto them, and a low deck loaded with a machine at the rear can put more on one axle than the arithmetic on paper suggests. Tell us how the trailer is normally loaded.
• The 12T reinforcement – for special heavy-duty needs the same spoke-hub architecture is built to a heavier rating. It is intended for builds that genuinely work at that level, not as a safety blanket on a 6-tonne trailer.
• Rating is a ceiling, not a target – an axle that spends its life at the top of its range wears faster than one with margin, and the difference shows up in bearings and spindles long before it shows in the beam.
• Match the rest of the running gear – a 12T axle under a suspension or tyre set rated lower does not make the trailer a 12T trailer. The lowest-rated component in the chain sets the limit.
• Where the heavy-duty case fits – where the build is a spoke axle for heavy-duty trailer applications, the rating is normally set by the trailer's gross weight and the number of axles sharing it, and that pair of numbers is the first thing we ask for.

Applications

Low-bed and flatbed trailers

With braking handled by the tractor unit or a separate trailer system, this axle sits under the deck and carries the machinery load. The custom track and wheelbase let a builder match the deck width and the hanger positions in one order.

Utility and cargo trailers

General freight, plant hire and workshop trailers that run without their own brakes. The spoke hub takes the 20-inch spider wheel most of these builds are specified with, and the plated finish suits regular washing and inland duty.

Agricultural and towed machinery

Field trailers, chaser bins and implements that work at low speed and are towed by a machine with its own braking. A non-braking spoke axle keeps the trailer simple, and the galvanized finish earns its place in slurry, fertilizer and wash-down conditions.

Special-purpose and custom builds

Generator and compressor skids, mobile stands, boat-yard trailers and one-off assemblies where the axle has to fit a chassis that was never designed around a catalogue part. Sending a drawing is the normal route here.

Refurbishment and replacement

Second-life trailers being re-geared, and units whose original axle is no longer available. Measure the old hub faces and axle centres and the replacement is built to the same geometry rather than forcing the chassis to change.

Where brakes belong instead

Any trailer that runs at highway speed or above the braked weight threshold in your market should be built on a braked axle from the same series. If you are unsure which side of that line your trailer falls on, describe the duty and we will tell you honestly which configuration to order.

- Track length set to your chassis – the hub faces are positioned to the deck width you specify, so wheels and fenders line up on the first fit instead of needing spacers or adaptor plates. - Wheelbase matched to the trailer – on tandem and tri-axle builds the axle centres follow your hanger positions, which keeps spring centres and mounting plates in agreement. - Spoke hub sized around the wheel load – as a spoke axle for heavy-duty trailer applications, the hub flange and stud circle carry the load through 5 or 6 studs on a 20-inch spider wheel pattern rather than through a light utility hub. - 45# steel as the standard beam – a medium-carbon grade that quenches and tempers predictably and keeps toughness under shock; 20CrMnTi is available where the duty needs more core strength. - Quenched and tempered to HRC 28–32 – the beam is treated as a whole section rather than surface-hardened, so it stays tough instead of brittle when the trailer works rough ground. - Electroplated or galvanized – choose plating for dry inland work, or galvanizing where humidity, coastal air and winter salt are part of the week. - Capacity raised to 12T on request – special heavy-duty jobs can be built on the same spoke-hub architecture at the higher rating. - No brake hardware to maintain – no chambers, no air lines, no linings to inspect, which keeps the trailer simpler and removes a maintenance item between services.

Specifications

Track Length Options

• What the figure measures – track length is the distance across the axle from one hub face to the other on the assembled unit. It is not the overall width and it is not the spring centre distance, so measuring the wrong face is the most common cause of a return.
• Standard window – the regular range is set out in the specifications, and it covers most utility, cargo and low-bed decks built on this hub type.
• Outside the window – we build to the drawing. Send the hub-face dimension, or the overall width you need to end up with, and the beam is cut and the hubs positioned accordingly.
• What changing it does – a wider track buys stability and wheel-to-frame clearance; a narrower one helps in tight yards and on narrow site roads. Both change where the fenders have to sit.
• How to measure a replacement – put the trailer on level ground, measure across the hub faces on the old axle, and note the wheel offset as well, because a different wheel can shift the tyre outboard even at the same track.
• Check the width rules where you operate – overall vehicle width limits vary by market, and a wide track plus a deep wheel can push a trailer over the limit. Confirm before the build is released.
• Sign-off governs – the dimension on the approved drawing is the one we build to, so check it before production starts rather than after the beam is finished.
• Wheelbase is the spacing between axle centres, and on a tandem or tri-axle trailer it decides far more than deck length. Move the axles apart and the load spreads over a longer footprint, which softens the ride and reduces the load transfer onto the rear axle during braking; move them together and the trailer turns in a tighter space but scrubs its tyres more in a slow, hard turn. The spacing is set to your requirements rather than to a fixed list, and the standard window is given in the specifications. What we need from you is either the trailer model and drawing, or the measured distance between the existing spring centres — the axle centres we build to have to agree with the hanger positions already on your chassis, otherwise the beam arrives correct but the suspension does not line up. On a single-axle trailer there is no wheelbase to set, and the track length figure does all the work. On a multi-axle build, settle the spacing before the beam goes into production; changing it afterwards means a new beam rather than an adjustment. If you are matching an existing trailer, send both the wheelbase and the track length together. They interact: a wider track or a deeper wheel can change the clearance between tyres on adjacent axles, which is exactly the kind of detail that is less costly to fix on a drawing and expensive to fix in a workshop.

Installation & Commissioning

1. Check the axle against the approved drawing before it goes anywhere near the trailer: hub-face track length, axle centres, stud count, P.C.D. and beam diameter. A discrepancy is far easier to settle on the floor than after the suspension is bolted up.
2. Lift and support the trailer on stands under the chassis, never under the axle, then position the beam so the spring seats or mounting brackets land on the suspension pads already on the trailer.
3. Fit the U-bolts or mounting clamps and bring them up evenly in stages rather than tightening one side fully first, so the beam seats square and does not pull the spring pack out of line.
4. Fit the hubs and wheels, checking that the stud threads are clean and undamaged and that the nut seat matches the wheel. Bring the nuts up in a cross pattern and finish to the torque your chassis or wheel supplier specifies.
5. Check the geometry once the trailer is back on its wheels: measure diagonally between opposite hub faces to confirm the axle is square to the chassis, and check tyre-to-frame and tyre-to-fender clearance through the full suspension travel.
6. Run the trailer unladen for a short distance, then loaded, and re-check the wheel nut torque and hub temperature afterwards. A hub that runs hot on the first trip is telling you about bearing seating or nut torque, not about the beam.
7. Grease and inspect the bearings at the interval your maintenance schedule sets, and keep the machined spindle surfaces coated if the trailer is going to stand for weeks between jobs.

Delivery & Order Confirmation

Typical lead time is 15 to 30 days for standard specifications, and 30 to 45 days where the axle is built to custom dimensions. Those are working figures rather than promises for a specific date, so confirm the current schedule with your sales contact when the order is placed.

The clock starts when the drawing is signed off, not when the enquiry is sent. Once the drawing is approved, your build slot is booked with the spoke axle manufacturer and the beam goes into the production sequence.

Before release, six things need to be fixed: track length, wheelbase, beam diameter, stud count and P.C.D., steel grade, and surface finish. The capacity rating sits alongside them. If any of these change after the order is released, the build is re-planned rather than adjusted, and the lead time moves with it.

Ask for the packing list and the document set to be sent ahead of shipment so your broker can review them. If you are working to a project deadline, tell us the date at the enquiry stage — it is easier to plan a realistic schedule at the start than to compress one later. Any warranty terms for your order are confirmed in writing with the order confirmation, and the technical support line stays open after delivery for fitting questions.

Every axle is coated with an anti-rust preparation on the machined faces and stud threads, wrapped in stretch film, and fixed onto a wooden pallet or a steel rack so it cannot shift in the container. The film keeps road dust and moisture off during the crossing; the pallet or rack is what lets the unit be lifted and moved without a sling rubbing against a spindle. Handle it as heavy steel. Use a crane with slings rated for the load, or a forklift under the pallet or rack, never under the beam alone — a beam lifted on one side will drop and a hub that lands on concrete is a hub that needs replacing. The approximate axle weight is listed in the specification table above, and the figure varies by model, so check the packing list rather than assuming. On arrival, unwrap and inspect before signing the delivery note: look for a bent bracket, a scored spindle, damaged stud threads or a broken pallet foot. Photograph anything that looks wrong before the film comes off completely, because that is what a freight claim rests on. If the axle is not going straight onto a trailer, store it under cover, off the ground, on its pallet or rack, with the anti-rust coating left on the machined surfaces. Re-coat any bare metal before fitting if the unit has stood for a long period.

- Sea freight – the usual route for export orders, shipped as a full container load or consolidated as less-than-container load depending on the volume in the order. - Land and rail – available for destinations reached overland, arranged around the route that suits your location. - Departure ports – Shanghai and Ningbo are our standard ports of departure; other ports can be discussed if they shorten the inland leg for you. - Document set – commercial invoice, packing list, bill of lading, quality certificate and origin declaration travel with the shipment, so the customs file is complete when the container arrives. - Consolidation – axles are frequently shipped alongside suspension sets, chassis components or other items from the same order; tell us what else is in the shipment and we will plan the loading around it. - Shipping advice – booking details and the loading plan are sent to you once the shipment is on the water, so your forwarder can prepare clearance in advance. - Arrival handling – confirm with your forwarder that lifting equipment is available at destination; a palleted axle is not something to move by hand.

Technical Support & Model Matching

Specification questions should not hold up an order. Send us your drawing, load rating and mounting dimensions, and our team will confirm the right model and configuration, cross-check it against the unit it will go on, and flag anything that needs changing before the order is released to our manufacturing partners. After delivery we stay involved: fitting and commissioning guidance, fault diagnosis, spare-part identification, and customisation coordinated with those long-term partners. Every enquiry is answered within 24 hours, and clear warranty terms sit behind the supply.
