Precision bearings are critical components in machine tools, directly influencing machining accuracy, operational stability, and overall efficiency. These specialized bearings are designed to handle high-speed rotations, heavy loads, and the demanding conditions of modern manufacturing environments. Whether used in CNC machining center, lathes or milling machines, precision bearings play a vital role in ensuring smooth motion, minimal vibration, and optimal performance.

Angular Contact Ball Bearings

One of the key advantages of angular contact ball bearings is their ability to sustain combined loads, making them widely used in high-speed spindles, precision machine tools, and automation systems. The contact angle—typically available in 15°, 25°, or other customized angles—affects their axial load-carrying capacity, with a higher contact angle providing greater axial stiffness. This makes them particularly suited for applications where precise positioning, minimal deflection, and smooth operation are critical.

Ball Screw Support Bearings

Unlike standard ball bearings, ball screw support bearings are engineered with a high contact angle, typically ranging from 60° to 90°, to efficiently handle axial loads in one or both directions. This high contact angle ensures superior rigidity and minimizes axial displacement, which is essential for maintaining precision in linear motion systems. By reducing backlash and increasing stiffness, these bearings contribute to the overall accuracy and efficiency of the ball screw assembly.
