Precision Angular Contact Ball Bearings
Precision Angular Contact Ball Bearings include 15° (Code C), 25° (Code AC), and 40° (Code B). The greater the contact angle, the larger the capacity to carry an axial load, but the lower the speed limit. Therefore, the bearing with the contact angle of 15° is used on the shaft with high speeds and small axial load. Otherwise, the Angular Contact Ball Bearings with a contact angle of 25° or 40° should be used.
HGT Precision Hybrid Ceramic Ball Bearings (Code HQ1) can significantly increase the spindle speeds, rigidity, reliability, and productivity. Moreover, this type of bearings can dramatically reduce the friction heat of the spindle and extend the service life.
