Shafts and bearing system: Fly Wheel shaft and roller shaft are made of carbon steel C45. These shafts are fixed to the body of crusher by 22 series heavy-duty bearings and protected from dust and other influences by labyrinth seals. The hubs of rollers are made of cast iron and locked to the shaft by a special conical sleeve locks.

Bearing Fit on Shaft and in Housing Proper itting of roller bearings to shafts and in housings also is critical to performance. If the it is too tight or too loose, problems including creep, excessive vibration and premature failure may occur. Recommended it values should be re-visited each time crusher bearings are replaced or repaired.
