Rolling-element bearing - Wikipedia

A rolling-element bearing, also known as a rolling bearing, is a bearing which carries a load by placing rolling elements (such as balls or rollers) between two bearing rings called races.The relative motion of the races causes the rolling elements to roll with very little rolling resistance and with little sliding.. One of the earliest and best-known rolling-element bearings are sets of logs

Angular Contact Ball Bearings - an overview

For self-aligning roller bearings (Fig. 4.6b), the preceding relations are valid for each roller, and the total axial force is zero. For tapered roller bearings (Fig. 4.6c), there are three contact angles: α i, the contact angle for the inner ring; α e, the contact angle for the outer ring; and α f, the contact angle for the frontal face.

Greases for slow and steady wind turbine bearings - STLE

Lucas notes that tapered roller bearings (TRB) are beginning to replace spherical roller bearings (SRB) for main shaft appliions, especially in the larger offshore wind turbines. Because tapered bearings can better support high thrust and radial loads, a smaller tapered bearing can be used, and it can stand up to harsh conditions and

Tapered Roller Bearings Selection Guide: Types, Features

Tapered Roller Bearings Information. Tapered roller bearings contain an inner ring, outer ring, and a nuer of tapered rollers. Looked at individually, the inner and outer bearing rings are also tapered, reseling a cone segment. Due to the large surface area contact, tapered roller bearings are able to withstand heavy axial and radial loads.
