Bearing Fit on Shaft and in Housing

Proper fitting of roller bearings to shafts and in housings also is critical to performance. If the fit is too tight or too loose, problems including creep,

excessive vibration and premature failure may occur. Recommended fit values should be re-visited each time crusher bearings are replaced or repaired.

For instance, a shaft that has been reused repeatedly can be slightly smaller than the day the machine was commissioned.

An undersizedshaft – even at extremely small scales – can cause improper bearing fit and cause premature bearing failure.

Also, over time, bearing housings can get worn or become out of round. Both conditions can cause improper bearing support and premature failure.

If concerns about proper shaft and housing dimensions arise, operators should consult an expert to evaluate the proper bearing shaft and housing fits.
