SCR Crossed Roller Bearings

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
  • 6 construction types incl. custom SCR-X
