June 27, 2016 – IKO International introduced the CRBF Crossed Roller Bearings at IMTS. These specialized bearings feature a compact design, with rollers alternately crossed at right angles between inseparable inner and outer rings. Because the rollers make inline contact with the raceway surfaces, elastic deformation under load is minimal. Bearings can simultaneously accommodate loads from all directions, including radial, axial and moment loads.
IKO's CRBF crossed roller bearings feature numerous mounting holes on both the inner and outer rings, enabling fast and easy mounting without the need for special housings and fixing plates. The roller guidance system incorporates special separators between cylindrical rollers, allowing ultra-smooth and high-speed rotation.
Because the rotational torque of CRBF crossed roller bearings is low, the difference between static and dynamic torque capacities is small. This enables both lower power consumption and a reduced operating temperature rise, which increases overall machine efficiency.
Basic dynamic load ratings range from 2,910 to 84,300 N and the CRBF bearings' operating temperature ranges from -20° to +110° C. Ideal applications include industrial robots, machine tools, medical equipment and other machinery requiring high rigidity and superior accuracy in a compact footprint.
