Bearing housing FRM215/5 is a stabilisation ring used together with a fixed bearing, keeping the bearing assembly properly positioned within the housing seat. The outside diameter is 215.0 mm and the net mass is 117.17 g. Its function is purely mechanical stabilisation of a fixed bearing arrangement rather than load transmission. The ring supports correct axial location of the bearing in the housing, which is relevant wherever a fixed bearing position must be maintained without additional axial play at the ring interface.
