Roller bearings are more satisfactory under shock or impact loading than ball bearings. Ball-thrust bearings are for pure thrust loading only. At high speeds, a deep-groove or angular-contact ball bearing usually will be a better choice, even for pure thrust loads.

A needle roller bearing is a special type of roller bearing which uses long, thin cylindrical rollers resembling needles. Ordinary roller bearings' rollers are only slightly longer than their diameter, but needle bearings typically have rollers that are at least four times longer than their diameter. Like all bearings, they are used to reduce the friction of a rotating surface.

As load distribution varies cyclically in the bearing, the mechanical properties of the bearing also vary versus time (e.g., the number of rolling elements in the load zone affects the stiffness). Such variations can be a source of vibration and noise.

Bearing Friction. Rolling element bearings, such as ball bearings and roller bearings, are used in equipment primarily because they support the loads inherent to the machine's function at a much lower friction level than any oil film bearing, such as bronze or Babbitt.This reduces the power required to drive the equipment, lowering the initial cost of the prime mover and the energy to ...

Ian Hutchings, Philip Shipway, in Tribology (Second Edition), 2017. Materials for rolling elements and races. A primary requirement for the operation of a rolling element bearing is that deformation of its components should at all times be elastic, in view of the high stresses that result from contact between the balls or rollers and the tracks. The static load rating for a steel ball bearing ...
