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

» The SKF formula for rolling bearing life - Evolution

16/2/2001· SKF life formula. A simple analytical formulation for bearing life that includes consideration of the fatigue strength of the material evolved from the rolling contact fatigue model set forth by Ioannides and Harris (1985). This was initially applied in the numerical solutions of the fatigue risk of 3-D stress fields of rolling contacts.

Replenishment of the EHL contacts in a grease lubried ball bearing …

1/6/2020· 1. Introduction. The quality of lubriion of rolling bearings is primarily determined by the thickness of the Elasto-Hydrodynamic (EHL) film separating the balls from the raceways. If these films are too thin, metal-to-metal contact will induce shear stresses on the surfaces that will reduce bearing life.

Types of Bearings | Uses & Working Mechanisms Explained - …

25/8/2020· Ball bearings provide very low friction during rolling but have limited load-carrying capacity. This is because of the small area of contact between the balls and the races. They can support axial loads in two directions besides radial loads. Ball bearings are used for controlling oscillatory and rotational motion.

4/4/2018· Types of rolling contact bearings Deep groove ball bearing In this type of bearings, the radius of the ball is slightly less than the radius of curvature of the groove. This creates point contact. Thus friction is less and so it can be used in high-speed appliions.
