Thin Precision Crossed Roller Bearing

Thin Precision Crossed Roller Bearing

The thin precision crossed roller bearing is provided with two series, including the separable outer ring types and the single-split types. The separable outer ring types are compact with extremely thin inner rings and outer rings of RB type. It is applicable in the low weight and compact design, such as the rotating part of the robots and mechanical arms. The single-split types are designed with the same dimensions as RA types. Thanks to the notch in the outer ring, it achieves high rigidity. It is an ideal product in the outer ring rotating applications.
