Angular contact ball bearings for radial loads used in machine tools are bearings which inner and outer rings cannot be separated. This type of bearing includes series 78, 79U, 70U, 72, HSE9, HSE0, BNS9, BNS0, BNT9, BNT0 and BNT2. For angular contact ball bearings, an imaginary straight line connecting the contact points between the balls and inner and outer rings forms an angle with the radial axis. The optimal contact angle can be selected to meet functional requirements such as high speed or high rigidity.
