CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
End supports/bearings provide mounting points and rotational support for the ends of the ball screw shaft. They ensure proper alignment, minimize deflection, and support axial and radial loads while allowing controlled rotation, which is essential for smooth and accurate linear motion.
Commonly, angular contact bearings or deep groove ball bearings are used. The specific type depends on the application requirements, such as load capacity and precision. The bearing type is typically specified as angular contact per ISO 15 in the reference data.
According to the reference data, dynamic load ratings range from 5 to 120 kN, and static load ratings from 10 to 250 kN, per ISO 76. These values are for reference; actual ratings depend on the specific model and must be confirmed with the manufacturer.
Selection involves matching the shaft diameter (6–80 mm), load requirements, operating temperature, speed, and mounting dimensions. Verify parameters such as axial clearance, radial runout, and protection class against your application needs. Always consult the manufacturer for model-specific data and standards compliance.
