Crossed Roller Bearings

One race, every load direction

Crossed roller bearings arrange cylindrical rollers in alternating 90-degree orientation between inner and outer rings. The result is a single bearing that handles radial loads, axial loads in both directions, and tilting moments at the same time. That combination lets designers shrink the rotary envelope on machine tool tables, robot pivots, medical scanners, and semiconductor handlers without giving up rigidity.

All loads on one race. Alternating roller orientation supports radial, axial, and moment loads in a single bearing, so two-bearing arrangements can collapse into one.
Standard, slim, and super-slim profiles. Section heights from 5 mm slim profiles up to 150 mm full-section bearings cover thin-table robotics through heavy machine tool spindles.
Mounting-hole variants ready to bolt up. Mounting-holed CRBFV and CRBTF variants drop directly into housing plates without separate clamping rings or adapter flanges.
