RB USP SERIES CROSSED ROLLER BEARING
RB…USP series of JCB crossed roller bearing is consisted of an outer ring and an inner ring with a group of cylindrical rollers and spacers (or cages). The rollers are arranged between the inner ring and the outer ring, and spacers are placed between the rollers to prevent them from colliding with each other.
Description
