RB series crossed roller bearings, the outer ring is divided into two pieces, the inner ring is an integral structure, it is most suitable for the occasion where the inner ring has high rotation accuracy.This type of bearing is widely used in industrial robots, work machinery and medical facilities, etc., where high rigidity, tightness and high speed can still ensure accuracy.

RB Crossed Roller Bearings Features:

1. Excellent rotation accuracy. The RB series crossed roller bearings produced by LKPB, can provide negative clearance types, accuracy grades P5 / P4 / P2.

2. RB series cross roller bearings are specially suitable for the applications where space is limited, while high rigidity and high rotation accuracy are required. Such as joints and swiveling units of industrial robots, swiveling tables of machining centers, rotary units of manipulators, precision rotary tables, medical equipment, measuring instruments and IC manufacturing machines.

3. Withstand large axial and radial loads. Because the rollers are arranged perpendicular to each other on the raceway through the spacer, they are in line contact with the raceway, not point contact with the ball turntable bearing.

4. greatly save installation space.

5. Reduce the shaft length and processing cost. The thermal expansion causes limited changes in geometric dimensions.

6.Using nylon divider, low moment of inertia, low starting torque, easy to control angular division

7. Optimized pre-tightening force, high rigidity, high precision of guide roller operation Lubrication and Maintenance of RB cross roller bearings All RB series cross roller bearings products are pre-lubricated before delivery except stated otherwise. So they can be immediately put into application under normal working conditions, without extra lubrication during operating.

At the initial stage of running, bearings’ friction torque will increase temporarily, and will become stable along with running, after grease evenly coated the raceway and rollers. Generally bearings need to be re-lubricated every 1-6 months, based on the specific working conditions.

1. RB Crossed Roller Bearings Structure

RB series (outer ring division type with inner rotating), this type is the basic type of crossed roller bearings. The outer rings have two parts, and the inner ring is one integer. The type is well applied to the situation which need high rotation accuracy on inner ring. For example, it is suitable for the rotary part of the indexing table of the tools machine.
