Ball bearing - Wikipedia

A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races. The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. It achieves this by using at least two races to contain the balls and transmit the loads through the balls. In most

Ball Bearings: Guide to selection, appliions & calculations - …

XF r + YF a (3 for ball bearings and 10/3 for roller bearings) ( X = 1 and Y = 0 always). X and Y are factors required for the calculation of equivalent dynamic bearing load for single and double row deep groove ball bearing, dependent upon axial load (Fa) and radial load (Fr). Therefore, if P o < F r, P = P o = F r.

What is a Sleeve Bearing? (with picture) - Info Bloom

Sleeve bearings are a kind of plain bearing--that is, bearings with few moving parts. Many spherical ball bearings have an internal ring, which is lined with smaller balls inside. In contrast to regular ball bearings, a sleeve bearing only has two moving parts; the outer sleeve and the inner rotating cylinder.
