(1) the angular contact ball bearing deep groove ball bearing basic similar shape, there is a ring with only a wall, the other side slope. Compared with the same series of deep groove ball bearings with inner diameter specifications, the difference lies in the cage structure and with the slim ball bearing number of the steel ball a little more.
(2) in the deep groove ball bearing inner ring angular contact ball bearing with outer slope of the inner ring is completely general, such as the inner ring to the deep groove ball bearing 6204 generic row angular contact ball bearing 7204AC.
(3) the angular contact ball bearing retainer is real shape or stamped, no need of rivets.
(4) the limit speed angular contact ball bearing is higher than that of deep groove ball bearing the same size.
(5) can bear radial load, Taper roller bearings also can withstand a one-way axial load is larger, the contact angle is large ratio the bearing axial load and radial load is bigger.
(6) even bear radial load, also produce axial force, so the general angular contact ball bearings are used in pairs.
(7) the angular contact ball bearing Ding is, because of the effects of axial pre load after installation. Can eliminate bearing internal clearance, so relatively improve the rotation accuracy of R bearing. The application example in the machine tool spindle high precision, can make the radial and axial spindle runout minimum.
(8) two or more than two angular contact ball bearing group, can bear Excavator Slewing Bearing double direction axial load, or increase the bearing capacity of the single direction axial load.
(9) through the pre load can obtain more rigid and maintain long-term rotation precision characteristics of bearing the original.
