BS Series (TAC Series) Ball Screw Support Bearings
BS Series (TAC Series) Ball Screw Support Bearings are high-precision angular contact ball bearings designed for ball screw support applications. They offer high axial stiffness, low friction, and excellent positioning accuracy, ensuring smooth and reliable performance in CNC machines, precision machinery, and automation equipment.
Features
Design & Structural Features
✅ High-Purity Bearing Steel:The inner and outer rings are manufactured from high-purity bearing steel with strict control of oxide inclusions and other impurities that may negatively affect rolling contact fatigue life.
✅ High Axial Rigidity:Featuring a 60° contact angleand an increased number of steel balls, the optimized internal design provides higher axial rigidity and stiffness, making these bearings ideal for precision feed systems.
✅ Low Starting Torque:Compared with tapered roller bearings and cylindrical roller bearings, BS/TAC series bearings offer lower starting torque, enabling high-precision operation with reduced driving force requirements.
✅ Combined Load Capability:When used in matched pairs, these bearings can accommodate axial loads, radial loads, and combined loads, providing stable support for ball screw systems.
