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 2008-03-21 SKF Slide 14
SKF Total Shaft Solution Optimized loading with CARB and no axial friction Floating (non-locating) bearing seizes in housings causing axial loading, friction and heat Fr Fa Bearing seizes in housing F r CARB can not support axial loads. Shaft moves inside CARB. Fa = Fr x μ Fa = 0 Result is high loading in bearings Result is lower forces and temperatures 2008-03-21 SKF Slide 15
