Product Features of 7203 BEY Bearings

  1. high carrying capacity
    The low shoulder allows a large number of balls to be incorporated into the bearing, giving it a relatively high load carrying capacity.
  2. Good running performance
    Rapid acceleration and deceleration are possible.
  3. Easy to install universally compatible bearings
    No adjustments are required for correct internal clearance or preload.

Product classification of Angular contact ball bearings

FAQ of 7203 BEY Bearings

  • Angular contact ball bearings have different outer ring thicknesses on the marked and unmarked surfaces. This is due to the contact angle between the outer ring and the ball. Deep groove ball bearings have the same thickness on both sides of the outer ring. In addition, the ACBB has the designation 7xxx and the DGBB has the designation 6xxx.
  • Double-row ACBBs can withstand axial loads in both directions, but they have a limited contact angle. The ACBB arrangement or multiple single-row ACBBs can only carry axial loads in one direction, depending on how they are combined. However, these options do not limit the contact angle, allowing customised selection to best match the ratio of radial load to axial load. In addition, the clearance and accuracy of the ACBB arrangement is controlled as a group, resulting in a consistent level of vibration/noise and rotational accuracy. However, the use of two individually controlled single rows of ACBBs may lead to significant changes in their resultant characteristics when combined.
  • As the name suggests, the ball and the outer ring in the ACBB are in diagonal contact depending on the contact angle. A larger contact angle increases the inclined contact between the ball and the outer ring, which affects the ultimate speed and load carrying capacity.
