SKF Total Shaft Solution

•Eliminate problem of the non-locating bearing seizing in housing

•Reduce operating forces and temperatures

•Reduce vibrations

Typical Applications

•Fans

•Conveyors

• Impact crushers/hammermills

•Vibrating screens

•Gearbox (industrial & automotive)

•Grinding mills/Paper mills/ steel mills


Fr

Fa = 0

Optimized loading with CARB and no axial frictionFloating (non-locating) bearing seizes in housings causing axial loading, friction and heat

Bearing seizes in housing

Result is high loading in bearings

CARB can not support axial loads.

Shaft moves inside CARB.

Result is lower forcesand temperatures

Sealed SRB in conveyors

Sealed SRB increases MTBF (longer service life)

Real Value is to increase MTBF

Decrease in MTTR solutions (split SRB) have limited value compared in increase in MTBF

Sealed SRB increases MTBF
