FAQ

What do bearing model numbers mean?

Prefix = series (68=extra thin, 69=extra light, 60=light, 62=medium, 63=heavy). Suffix = bore code (00=10mm, 01=12mm, 02=15mm, 03=17mm, 04+ = 20mm+5mm/step).

How to select a bearing?

Match bore to shaft → pick series by load → verify Cr > equivalent dynamic load P.
