Before you order
Don't select by size alone
Matching bore, OD and width does not confirm a replacement. The bearing must also suit its original duty on the machine — the position, load and sealing it was built for. A size-only match can fit the shaft and still fail in the field.

Buyer questions
Ordering Inch Size Bearings: common questions
What should I send if the bearing markings are worn?
Send the machine model, the bearing position and photos of whatever markings remain. Add measured dimensions and a photo of the assembly if you can. With the machine details, we can match the Koyo / JTEKT reference even when the ring markings are unreadable.
Can I include machine part numbers in my enquiry?
Yes. Part numbers from the machine manual or your repair parts list help confirm the exact replacement. We check them against the bearing model and the application before quoting.
Will you change the specification without asking me?
No. Any technical change or alternative bearing is only supplied after you approve it. Identification gaps are settled first, then you receive a written quote with model, quantity, price, lead time and quote validity.
