PUB SE/P1 10919/2 EN June 2013. This publication supersedes publication 5300. SI conversion A ball bearing is a type of rollingelement 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 three races to contain the balls and transmit the loads through the balls. make bearing steels. Raw material.

Needle Roller Bearings NSK
maximizes load capacity. 11. Among full complement roller bearings, bearings whose rollers are held in place by grease before assembly have the maximum load capacity because the rollers have the longest possible length. 12. The cage of the needle bearing accurately guides the rollers at the pitch diameter of the rollers. SKF Ybearing units provide designers with considerable freedom of choice so that compromises can be avoided. Some 40 standard series Ybearing units are available. (➔ matrices on pages 16 and 17).
