High-precision thrust angular contact ball bearings for precision ball screw support are specially designed according to different uses and are divided into two types: high-rigidity series and high-load series. Suitable for high-precision feed mechanism.
1. High-rigidity series for machine tools with high axial rigidity and a special design to achieve good-precision rotation driven by a small driving force.
2. Among the high-rigidity series for machine tools, products with a seal ring have also been serialized.
3. High-load series for electric injection molding machines, the ball diameter and contact angle are optimally designed to increase the allowable load specifications and achieve a long life.
