Material and fit notes

Bearing accessory quotes depend on load position, material, tolerance, heat treatment, surface finish, and machining path.

For slewing bearing or rotating equipment parts, fit dimensions and hole positions should be checked from drawings or samples before quotation.

When the item is not a standard bearing, the RFQ should be treated as a drawing-based machined part rather than a generic catalog request.

Inner and outer diameter measurement
Width, step, groove, and hole position check
Material and hardness checkpoints where required
Surface finish and machining burr review
Sample approval, part mark, and export packing

Buyer questions

Practical answers before sending an RFQ.

Can you review bearing parts from drawings?

Yes. Drawings, dimensions, material, tolerance, quantity, and application position allow a supplier to review machining and production feasibility.

Can you quote a bearing accessory from a worn sample photo?

A photo helps start the review, but dimensions, material, fit position, and quantity are needed before a reliable quotation.

Are standard bearings and custom bearing accessories handled the same way?

No. Standard bearing models can be reviewed by model number, while housings, sleeves, seats, and bushings usually need drawings or measurements.
