Crossed Roller Bearings

SKF Cross Roller Bearings for Precision Rotary Motion

Cross roller bearings are used in compact precision assemblies that require controlled rotary or oscillating movement with combined loads. Common applications include rotary tables, indexing equipment, robots, machine tools, measuring systems and precision handling equipment. The exact bearing series, dimensions and mounting design should be verified before sourcing.

Key Selection Information

  • Full bearing reference, bore, outside diameter, width and mounting-hole pattern where applicable.
  • Radial, axial and moment load requirements from the equipment design.
  • Required rotational accuracy, preload, rigidity and operating speed.
  • Lubrication, environmental conditions and installation surface quality.

Replacement Review

Cross roller bearings are often integrated into a specific mounting arrangement. A close size match may not be sufficient if the raceway, preload, mounting holes or accuracy class differs. Provide the existing reference, a photo of the marking and the equipment drawing or dimensions when available.

Why is the mounting arrangement important?
