CRBF Crossed Roller Bearings Reduce Power Consumption
CRBF mounting hole type, crossed roller bearings are now available in shaft diameters from 10mm all the way up to 115mm.
Space-saving design. These specialized bearings feature a space-saving 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.
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.
Both open and sealed versions are readily available. The open structure is well suited to low-energy applications, due to the absence of any sealing friction, while sealed types feature synthetic rubber seals that provide excellent protection against dust and contaminants, as well as prevent grease from escaping.
Because the rotational torque of CRBF Crossed Roller Bearings is lower than that of traditional plain bearings, 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.
