ABSTRACT:
A conveyor roller has end caps forming housings for ball bearing units rotatably mounting the conveyor roller on a spindle, each housing having an end wall forming an abutment for locating the bearing in the housing, and the spindle having circlips abutting the bearing units. Each bearing unit has inboard and outboard seals mounted on the outer bearing ring, and the inboard seal is formed with projections which are compressed axially with permanent deformation between the inboard seal and the end wall of the housing, so as to function as a spacer. The projections are spaced symmetrically around the axis of the bearing unit, and each projection is symmetrical about a radial plane through the center of the projection. The projections are formed integral with the seal or consist of separate V-shaped elements mounted in slots in a side face of the seal. The inboard seal is formed with a recess for each projection, the recess having a depth to accommodate the projection when in a fully collapsed condition.
