Roller bearing i.e. ball bearing, for use in transmission of motor vehicle, has lubricant-permeable sealing elements for preventing penetration of particles into bearing and closing corresponding annular gaps between outer and inner races

摘要

The bearing (10) has lubricant-permeable sealing elements (16, 17) i.e. sealing disks, for preventing penetration of particles into the bearing and closing corresponding annular gaps (18, 20) between an outer race (12) and an inner race (14). A particle size to be filtered is adjustable by porosity of a material of the sealing elements. The sealing elements are made of a sintered material, textile material, ceramic material or plastic, where lubricant i.e. oil, penetrates through the annular gaps for lubrication of the bearing.
