Spherical roller bearings operate in arduous condi-tions. The spherical rollers can be symmetrical or unsym-metrical and are self-aligning in the outer ring sphered raceway. Thus, the possible coaxiality deviations of the supporting bearings as well as shaft bending can be compenmore...
Needle roller bearings can be considered a version of cylindrical roller bearings. As these small-sized bearings can take over heavy dynamic loads, they provide high stiffness in bearing units. Needle roller bearings are manufactured in the follow-ing constructive versions: Needlmore...
Tapered roller bearings have the rolling elements under the form of frustra of cones. They roll on tapered surfaces which, if extended, converge towards a single point on the bearing axis. The rollers are guided tangentially by the cage and axially by the big rib of the outer rinmore...
