ABSTRACT:
The horizontally mounted rotational bearing arrangement for high speeds of rotation is mounted in a casing in two radial rolling bearings. Each radial rolling bearing comprises rolling members guided by an associated cage, and further comprises a groove provided at the shaft and operative as an inner race, as well as an outer race. A respective slinger ring is disposed between each radial rolling bearing and associated cover plate. An impingement surface extends around the associated slinger ring and is in alignment with an operative edge of such slinger ring. This impingement surface is effective for returning lubricant to the rolling members of the associated radial rolling bearing. The cage of each radial rolling bearing is constructed such that by virtue of its movement in operation, the lubricant is conveyed to the rolling members of the associated radial rolling bearing. The rotational bearing arrangement has the advantages of substantially obviating the entry of dirt into the interior of the rotational bearing arrangement and, more particularly, egress of lubricant therefrom.
