FAQ 

Q：Can thin shim compensate worn outer surface and loose fit?
A：Not recommended. Shim causes uneven load, cup shifts and spalls under heavy impact.

Q：What is the risk if only the cup is replaced while cone and rollers remain?
A：Mismatched contact angle leads to stress concentration and rapid pitting.

Q：What risk exists if hammering cup end with copper bar?
A：Impact induces hidden subsurface stress, which causes large-area spalling later.

Q：Does overheating final drive mean the bearing cup is damaged?
A：Check grease, contamination and preload first, then inspect cup raceway by NDT.
