High Quality Bearings

Ball screw pair is a precise, efficient and sensitive transmission element. In view of the difficulty of processing ceramic materials, precision ceramic bearings are mostly hybrid ceramic ball bearings with ceramic rolling elements and inner and outer rings made of chrome steel.

The requirements and selection are the same as ordinary mechanical transmission bearings. With the rapid development of numerical control technology, 'composite, high speed, intelligence, precision, and environmental protection' has become the main trend in the development of today's machine tool industry technology. Ceramic bearings are more and more widely used. For high-speed and high-precision machine tools such as CNC machine tools and machining centers, For spindle support, ultra-precision bearings of P4 and above are required.

Therefore, high-performance machine tools must be equipped with high-performance bearings. In addition to using high-precision screws, nuts and balls, attention should be paid to the selection of bearings with high axial rigidity, small friction Wheel Bearing torque and high running accuracy.

As the basic accessory of the machine tool, the performance of the spindle bearing directly affects the speed, rotation accuracy, rigidity, anti-vibration cutting performance, noise, temperature rise and thermal deformation of the machine tool, and then affects the accuracy and surface quality of the machined parts. This requires the machine tool spindle and its related parts to adapt to the needs of high-speed machining. At present, the most widely used ball screw support is single-row thrust angular contact ball bearings with a contact angle of 60°
