Roller bearing with cylindrical rollers

Abstract

A roller bearing having cylindrical rollers between inner and outer coaxial rings, each of the rings being an integral piece, is fully loaded by insertion of cylindrical rollers through a feed notch. To retain the cylindrical rollers against dropping back through the feed notch, a retaining ring closed in a loop is provided to rest on or in a rim retaining the rollers axially and having the feed notch. The retaining ring, which can also have a sealing part closing the end of the bearing, is mounted such that the retaining ring, the sealing ring and/or a filler piece adapted to fit directly in the feed notch, rests against the open end face of the cylindrical rollers behind the feed notch. The process by which the bearing parts are assembled and secured includes the steps of filling the inner ball race tracks, axially assembly the inner and outer rings, and inserting the rollers for the final ring through a feed notch, thereby axially restricting displacement of the inner and outer rings, and finally retaining the rollers in place by means of the retaining ring. The retaining ring and filler piece can be of metal or relatively harder plastic; the sealing ring can be of relatively softer plastic appropriate for seal packing.
