Abstract: A bearing assembly for a shaft or similar that is axially guided with precision in a housing. The shaft is stressed to differing degrees and/or for different periods of time in the two axial directions. The bearing assembly has a single-row angular contact ball bearing and a single-row cylindrical roller bearing. The angular contact ball bearing is designed to receive the greater main axial load that is exerted during operation, whilst the smaller axial force that acts in opposition is absorbed by the cylindrical roller bearing in addition to the radial forces. The quantity of equipment required to absorb the small axial force that in general is only exerted periodically can be kept to a minimum. In addition, a predefined axial play is pre-set in the unit and a defined lateral ring overhang is set between the inner and outer ring.

Abstract: A bearing composed of an inner race, two outer races concentric therewith and spaced axially from each other to leave a gap between them. Sets of ball bearings are located between the inner race and each of the two outer races. The outer races are provided with shoulders projecting axially toward one another and the whole is secured by a band wrapped circumferentially around the shoulders.

The band is somewhat longer than the circumference and the ends are turned radially outwardly and fastened together.In a particularly improved form of the device, frames are located in the gap and are releasably fastened to one another. The width of the gap is larger than the thickness of the frames, so that there is a certain amount of play in the bearing. This provides a self-aligning feature.
