I. Introduction A. Definition of Ball Bearings At its core, a ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races. Its primary functi...
RA series cross roller bearing is a kind of small size and lightweight cross roller bearing in which the wall thickness is thinner. it is small and can withstand heavy loads. the one-piece inner & outer ring structure provides high rigidity, high accuracy, and smooth rotation; suitable for inner and outer ring rotation. The ly small cross-sectional area allows it to be used in lightweight, compact devices, such as rotating parts of robots and robotic arms.
