Antifriction bearing, method of making same and antifriction material for performing this method

Abstract

The unoccupied space intermediate the races, the rolling bodies and the metal cage of a conventional antifriction bearing is filled with a solidified antifriction compound, with the cage of the conventional bearing being fast with the compound and reinforcing it. An annular gap is provided intermediate the outer race of the bearing and the solidified compound body for removal of the wear products. To manufacture a bearing of this kind, a bearing of the conventional kind is filled with a solidifiable antifriction material, with subsequent thermal treatment. The invention offers a simple, readily implementable and relatively inexpensive technique of adding a new quality to conventional antifriction bearings, viz. the ability of prolonged operation under adverse conditions, without periodic lubrication.
