They can compensate for chain stretch resulting from operation and give smoother system running under high loads and speeds. In series KSR..-B0, the inner ring is located on the shaft by means of a locking collar. The bearing bore of this series has a plus tolerance. As a result, unmachined shafts up to ISO tolerance h9 can be used under moderate loads and speeds.
