1 TYPES AND FEATURES OF ROLLING BEARINGS

Tapered Roller Bearing Spherical Roller Bearing Single-Direction Thrust Ball Bearing For high speed operation however the smaller contact angles are preferred Usually two bearings are used in duplex pairs and the clearance between them must be adjusted properly

The Structure And Performance Of WSBC Bearing

Since the rolling elements in thrust tapered roller bearings are tapered rollers the rolling generatrix and the raceway generatrix of the washer are structurally converged at a certain point on the shaft center line of the bearing so the rolling surface can form pure rolling and high limit speed For thrust cylindrical roller bearings

Rolling

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

Modeling and Dynamic Analysis of Spherical Roller Bearing

Since spherical roller bearings can carry high load in both axial and radial direction they are increasingly used in industrial machineries and it is becoming important to understand the dynamic behavior of SRBs especially when they are affected by internal imperfections This paper introduces a dynamic model for an SRB that includes an inner and outer race surface
