Angular contact ball bearings in connection with the radial inner
and outer rings and ball point of contact at an angle. The contact
angle is generally divided into 15 °, 30 °, 40 °, represented by
the letters C, A, B represents, NSK special production for such
bearing contact angle of 25 °, with the A5 represents.
Angular contact ball bearings mainly take large axial load, the
greater the contact angle, the greater the load capacity to
withstand. Cage materials are steel, brass or engineering plastics,
molding methods are different selection stamping or turning,
depending on the form or the bearing conditions.
There are other combinations of angular contact ball bearings,
double row angular contact ball bearings and four-point contact
