RE Series Crossed Roller Bearing

RE standard type is an innovative bearing based on the design of the RB standard type bearing. The inner ring is separable while the outer ring is integrated into the main body. It is used in cases where the high rotational accuracy of the outer ring is required.

Description

Crossed roller bearings are lightweight, compact bearings with thinnest possible inner and outer rings with high rigidity, because of its vertical arrangement of cylindrical rollers with a 90°V groove through the separate spacers in the deep groove rolling surface. This special design allows just one bearing to carry loads in all directions including radial, axial and moment loads.The crossed roller bearing has high precision, and because the spacer is installed between the vertically arranged rollers, it prevents the rollers from falling over or the rollers rubbing against each other, so it can prevent the increase of the rotational torque. In addition, compared with conventional types using iron plate cages, one side of the rollers does not come into contact or lock up. Stable rotational motion can be obtained even when a preload is applied. And since the inner ring or the outer ring is divided into two parts, the preload can be adjusted, so the rotational motion can be obtained.
