  • Angular contact ball bearings can withstand both radial and axial loads. Can work at higher speeds. The larger the contact angle, the higher the axial load carrying capacity. The contact angle is the angle between the line connecting the contact point of the ball and the raceway in the radial plane and the vertical line of the bearing axis. High precision and high speed bearings typically take a 15 degree contact angle. Under the axial force, the contact angle will increase.​

  • Precision bearings are classified according to ISO grading standards: P0, P6, P5, P4, P2. The grades are increased sequentially, of which P0 is ordinary precision, and other grades are precision grades. Of course, different grading standards, different types of bearings, their grading methods are different, but the meaning is consistent. The performance of precision bearings requires that the rotating body has high runout precision, high speed rotation and small friction and friction changes.
