Precision angular contact ball bearing is a kind of high-precision ball bearing. Its inner and outer rings and rolling elements are precision machined, which has high precision and rotation accuracy. This kind of bearing is suitable for mechanical equipment that requires higher precision and speed, such as high-speed spindles, CNC machine tools, grinders, etc.

Precision angular contact ball bearings have the following characteristics:

1. High precision: After precision processing, it has high precision and rotation accuracy.

2. High speed: suitable for mechanical equipment such as high-speed spindles that require higher speed requirements.

3. High rigidity: It has high rigidity and can withstand large axial and radial loads.

4. Long life: Made of high-quality materials and advanced technology, it has a long service life.

5. Low friction: Using special lubricant and sealing structure, it has low friction coefficient and friction torque.

6. Easy to install and maintain: simple structure, convenient installation and maintenance.

Precision angular contact ball bearing is a ball bearing with high precision, high speed, high rigidity, long life and low friction. It is suitable for mechanical equipment requiring higher precision and speed requirements.
