A roller thrust bearing having an increased efficiency and a reduced operating noise level includes a plurality of cylindrical roller elements radially oriented within a circular bearing cage which has inner and outer cage diameters and upper and lower cage surfaces. The roller elements protrude above and below the upper and lower cage surfaces, respectively, and upper and lower circular races having inner and outer diameters, are in rolling contact with the portions of the roller elements protruding above and below the upper and lower cage surfaces. The upper and lower races have features for reducing roller skidding against the races and for reducing operating noise of the thrust bearing. Another race feature allows the load carrying capacity of the bearing to vary to be proportional to the imposed load.

The diametral variations around the circumference of a bearing roller are measured by mechanical-to-electrical transducers which convert the diametral variations into electrical signals which are functions of the variations. The frequencies of the electric signals are converted into electric spikes which are proportional to the actual effect on roller noise of the frequency represented by each spike. The spikes are electrically added and a print is made of a value which is proportional to the expected noise the roller will produce when used in a roller bearing.

Rollers having a cylindrical configuration without substantial end relief are positioned between and exert a force against an outer raceway contact area and a cylindrical inner raceway contact area. The outer raceway has a crowned configuration such that a calculated maximum contact stress over the outer raceway contact area is controlled with respect to the maximum contact stress over the inner raceway contact area in order to make the outer raceway life substantially equal to the inner raceway life.

An annular shoulder on the radial bearing is contacted by the thrust bearing raceway radially inwardly from the inside periphery of the thrust bearing cage. Either the thrust race or the annular shoulder on the radial bearing, or both, may have an integral axial extension with the thrust race and the radial bearing interlocking radially inwardly from the inner periphery of the thrust bearing cage. The bearing is pressed in to the bore of the housing by pushing against the thrust race with the force against the thrust race being transmitted by way of the annular shoulder to the radial raceway. Thus, it is not necessary to push the bearing into the housing bore by pressing against the thrust rollers which often results in critical damage to the thrust race.

An annular band fits over a thrust washer of a thrust bearing. At least one but preferably a plurality of circumferentially spaced radially extending protrusions are provided on the annular band. The protrusions are adapted to provide an interference fit between the thrust washer and the support such as a housing on which the thrust washer is mounted.
