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

Introduction to Roller-Bearings and Damage Analysis

The rolling elements of tapered roller bearings are truned cones. Tapered roller bearings use conical rollers that run on conical races. Most roller bearings only take radial or axial loads, but tapered roller bearings support both radial and axial loads, and generally can carry higher loads than ball bearings due to greater contact area.

The Influence Of Rolling Bearing Profiling On Rigidity And

Oct 08, 2020· If the rolling elements are perfectly cylindrical (cylindrical roller bearings) or tapered (tapered roller bearings), this leads to local pressure peaks when the end side of the rolling elements comes into contact with the raceway (Figure 1a). This can result in local pitting damage in these areas (Figure 2). To avoid these pressure peaks

Smearing When cylindrical roller bearings are being

Smearing When cylindrical roller bearings are being mounted, the ring with the roller and cage assely is often entered askew and isn''t rotated. The rollers then scratch the raceway of the other ring, causing smearing. The rollers may be smeared too. During the mounting operation, the ring with the roller and cage assely has been entered askew on the other ring.
