When the bearing does not exist, is obsolete, or the drawing is the only authority: we make it to drawing or reverse-engineer it from a sample, from 50 pieces upward.
| Scope | Non-standard dimensions, materials, cages, clearances, seals, coatings and markings |
|---|---|
| Input | Drawing (2D/3D), a sample, or a dimensional survey of the housing and shaft |
| Minimum quantity | Typically 50–500 pcs, depending on size and tooling |
| Lead time | 4–10 weeks · 2–3 weeks for a sample or a small pilot batch |
| Documentation | FAI report, material certificate, dimensional report, PPAP-style package on request |
| Tooling | Usually no hard tooling for turned rings; forged or stamped parts may need a die |
| First step | Send the drawing or the sample photos with the three boundary dimensions |
Before designing a new part, check whether a standard one can be modified. Modifying an existing ring is usually faster and cheaper than making a new one, because the forging, heat treatment and grinding processes already exist.
| Route | Best when | Minimum | Lead time | Cost |
|---|---|---|---|---|
| Modified standard | Only a dimension or a feature must change | Low | 2–4 weeks | 1.5–3× standard |
| Made to drawing | The part is genuinely special | 50–500 pcs | 4–10 weeks | 2–5× standard |
| Reverse-engineered from sample | The drawing is lost and the machine is obsolete | 50 pcs | 5–10 weeks | 2–5× standard |
| Interchange to another brand | An equivalent exists in the catalogue | 1 pc | Same day | Standard price |
A cross-reference may solve it before a drawing is needed.

Yes. Send the sample or good photographs with dimensions. We measure it, produce a drawing for your approval, and manufacture to that drawing. Wear means the original dimensions must be inferred, so the approval drawing matters.
Four to ten weeks for production, two to three weeks for a sample. The variables are material availability, heat-treatment lot scheduling and whether new tooling is required.
Often, yes — a non-standard bore or width, a groove, a special clearance or a different cage can be applied to a standard ring. It is cheaper and faster than a new part, and we will propose it if it works.
Yes: material certificate, FAI report against the approved drawing, and a dimensional report. For automotive or medical programmes, a PPAP-style package with capability studies is available on request.
Send the drawing, the model list or the failure report. We reply with a scope, a price and a lead time within 30 minutes on working days.
