Custom Precision Shafts Made to Drawing
We source stepped, keyed and splined shafts for machinery and automation. Send us your drawing and quantities. We review the part with machining suppliers in China and coordinate quotations, samples and the checks you need before shipment.
- Order basis
- Your drawing and approved revision
- Machining
- Turning, with milling, spline machining or grinding as required
- Order quantities
- Samples and production batches, quoted to your requirements
Shafts for Machinery and Automation
- Stepped shafts
- For rollers, spindles and other assemblies that locate bearings or seals on different diameters. Include the journal fits, shoulder spacing and any corner clearance needed for assembly.
- Keyed and threaded shafts
- For drives that carry a pulley, gear or coupling. Specify the keyway dimensions and location, as well as the thread callout and usable thread length if a nut retains the assembly.
- Splined shafts
- For shafts that engage a matching drive hub. Include the spline standard or tooth profile, the fit and the engaged length. A mating hub drawing is useful when the spline callout is incomplete.
Bearing Fits, Machining and Finish
On a roller shaft supported by two bearings, both journals can be within their diameter limits and still fail a specified runout check. A bearing ring can also stop short of its shoulder if the corner radius is too large for the ring to clear. If these features govern assembly, mark the bearing seats and shoulders on the drawing and tell us which datum the supplier should use for inspection.
For carbon steel, alloy steel or stainless steel, send the exact grade and any material documentation you need. If the drawing calls for hardened and ground journals, ask for the quote in that finished condition. A price for a turned blank will not tell you what the complete shaft costs. We can check whether machining, heat treatment, grinding, finish and inspection are included, and bring any proposed substitutions back to you for approval.
From Sample Approval to Repeat Orders
If you need a first article, let us know what you will check before releasing the batch. For a shaft with a close bearing fit, that might mean measured journal diameters and runout on the finished part, alongside your own trial assembly. When the drawing specifies roughness, hardness or case depth, agree on the checks and records the supplier will provide before placing the order.
For repeat batches, we can coordinate checks against the approved drawing revision, keep the inspection records tied to the order and confirm packing for the finished parts. Ground journals and threads can be separated or protected in packing where the order requires it.
What to Send for a Shaft Quote
Start with the latest 2D drawing and the sample and batch quantities. A STEP file is helpful, but the drawing should state the material, critical fits, tolerances and finish. If a bearing, seal or hub controls the fit, send its part number or mating dimensions. Include the delivery destination, target date and any reports you need with the order.

Can I request a quote for a sample and a production batch?
Yes. Send both quantities and let us know how you plan to approve the sample. We can ask suppliers to quote the sample and the batch separately so you can compare tooling, machining and inspection costs.
Can you source shafts with ground journals or heat treatment?
We can review both with machining partners. Specify which surfaces need grinding, the final size and roughness limits, and any hardness or case-depth requirements. The supplier can then confirm the proposed sequence and inspection scope.
Can you work from a worn shaft if there is no drawing?
Send photos, dimensions and details of the mating components to start the discussion. A worn surface may not reflect the original fit, so the final dimensions and acceptance requirements need to be agreed before manufacture.
Have a shaft drawing ready?
Send it with your quantities and the features that matter most to the assembly.
