Product Description:
40-302936 Earthmoving Glass RH Side WDO ClearA ball bearing is a type of rolling element bearing which uses balls to maintain the separation between the moving parts of the bearing.
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. Usually one of the races is held fixed. As one of the bearing races rotates it causes the balls to rotate
as well. Because the balls are rolling they have a much lower coefficient of friction than if two flat surfaces were rotating on each other.
Miniature ball bearings have become essential components in the rotating e
lements of various
equipments and machines. In response to the trend toward equipment and machinery that gets
smaller, more compact, thinner and quieter, we manufacture hundreds of kinds of miniature ball bearings, including specialized types, from extremely small bearings with a 1.0 mm bore diameter and a 3.0 mm outer diameter to bearings that are about 20 mm in outer diameter.
These are also available in inch Dimension. The most commonly used sealed and shielded bearings are usually given an extra 1 to 2mm in width in order to accommodate the shield plate, and to allow sealing in of the grease.
