Abstract

A roller bearing including inner and outer races defining an interior space therebetween, and a plurality of cylindrical rollers between the races, each race having opposite axial end surfaces, a seal situated at each end of the bearing, each seal including a loosely fitting flange ring extending radially between the races, the ring having an inner axial surface facing the axial end surface of the inner race, thereby defining facing end surfaces, the ring and the inner race respectively having bore surfaces, the inner race having at least one hole extending generally radially from the bore thereof to the interior space for supply lubricant to the interior space, and pressure equalizing passages communicating the interior space with the exterior of the bearing, the openings comprising at least one passage in one of the facing surfaces and at least one axial passage axially traversing the ring.
