Combined sliding ball bearing for supporting shaft in gear construction, has balls and rollers unroll on remaining shoulder surfaces, where bearing is formed as four-point ball bearing, so that running grooves have contact points

摘要

The combined sliding ball bearing (1) has an inner ring (2) and an outer ring (3), which are provided with respective running grooves (4, 5). Rollers (14) and balls (15) are guided between the running grooves in a retainer (16). The balls in the running grooves and the rollers unroll on remaining shoulder surfaces (10-13). The bearing is formed as four-point ball bearing, so that the running grooves have contact points (18-21), where the four point ball bearing has undivided bearing rings.
