The structure and properties of angular contact ball bearing

(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 

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 linear 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, 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 

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.‍
