listen to the pronunciation of ball-bearing
English - English
In common usage, an individual spherical ball, usually made of steel or other hard material, suitable for use in a ball-based rolling element bearing
In engineering, a bearing assembly which uses spherical bearing balls as the rolling elements
small metal ball which is used in pivoting devices
Servo's output shaft is supported with bearings for increased performance and accuracy
A ball bearing is a type of bearing in which the turning part is connected to the non-turning part only by balls that roll between the two parts Ball bearings are used in bicycle bottom brackets, freewheels, headsets, and hubs They are also occasionally used in derailer pulleys and brake calipers
Ball bearings are small metal balls placed between the moving parts of a machine to make the parts move smoothly. One of the two types of rolling, or antifriction, bearings (the other is the roller bearing). Its function is to connect two machine members that move relative to one another so that the frictional resistance to motion is minimal. In many applications, one of the members is a rotating shaft and the other a fixed housing. Each ball bearing has three main parts: two grooved, ringlike races and a number of balls. The balls fill the space between the two races and roll with negligible friction in the grooves. The balls may be loosely restrained and separated by means of a retainer or cage
An antifriction rolling type bearing containing rolling elements in the form of balls
A rolling-type bearing containing rolling elements in the form of balls
