SCR Crossed Roller Bearings

by SBB Tech Co., Ltd. · South Korea LISTEDMANUFACTURER

Models: 6
Range: 6 construction types incl. custom SCR-X

Overview

Crossed roller bearings with rollers set alternately at 90° in a V-groove raceway, so one bearing carries radial, axial and moment loads together. Spacer retainers between the rollers stop skewing and keep torque steady. Types differ in how the rings are split, and there are integrated-ring, high-precision and custom versions.

Key features

Takes radial, axial and moment loads in one bearing
Spacer retainers prevent roller skew
Compact cross-section, slim types available
Split-ring designs for inner or outer ring rotation
Integrated SCR-U with machined mounting holes
Custom SCR-X sized to the machine

Applications

Industrial robot joints
Rotary and index tables
Machine tool heads
Semiconductor and inspection equipment
