Roller bearing with filter discs between inner and outer race

摘要

The roller bearing has filtering side discs almost covering the region between the inner and outer race. These discs (5) seal against the inner ring (1) and have labyrinth columns extending outwards to the outer race (2), they are of porous or holed material. The discs have guide vanes (12) at set distances over the surface with holes (11) of defined size, which are aligned at an angle to the disk surface. The bearing cage has projections (8) also in the form of guide vanes.
