Angular contact ball bearing 

 

Angular contact ball bearing uses axially asymmetric races. An axial load passes in a straight line through the bearing, whereas a radial load takes an oblique path that tends to want to separate the races axially. So the angle of contact on the inner race is the same as that on the outer race. 

Angular contact bearings better support "combined loads" (loading in both the radial and axial directions) and the contact angle of the bearing should be matched to the relative proportions of each. The larger the contact angle (typically in the range 10 to 45 degrees), the higher the axial load supported, but the lower the radial load. In high speed applications, such as turbines, jet engines, and dentistry equipment, the centrifugal forces generated by the balls changes the contact angle at the inner and outer race. Ceramics such assilicon nitride are now regularly used in such applications due to their low density (40% of steel). These materials significantly reduce centrifugal force and function well in high temperature environments. They also tend to wear in a similar way to bearing steel—rather than cracking or shattering like glass or porcelain.

Most bicycles use angular-contact bearings in the headsets because the forces on these bearings are in both the radial and axial direction.

 

 

Angular contact ball bearing type:

Single row angular contact ball bearing: only carry a direction of the axial load, when in bear radial load, can cause additional axial force must be applied to the corresponding reverse load, therefore, the bearings are generally used in pairs.

Double row angular contact ball bearing: At the same time can bear radial and axial load joint load, limit shaft on both sides of the axial displacement.

Angular contact ball bearing main technical indicators: 

(1) Bearing precision index: More than GB / 307.1-94 P4 level accuracy 

(2) High-speed performance index: 1.3~1.8x 106 /min 

(3)Service life:more than 1500h

Feature: 
1) Load capacities are higher than deep groove ball bearings of same dimensions 
2) Used for bearing radial-axial combined loads or pure thrust loads
3) Low operating friction and high limiting speed 

Type: 
1). Single row angular contact ball bearings 
2). Double row angular contact ball bearings 
3). Four-point contact ball bearings 

Mounting 
/DB: Mount in duplex, back to back 
/DF: Mount in duplex, face to face 
/DT: Mount in duplex, tandem 

Tolerance & Precision.
Accuracy from low to high is expressed as P0 ( general ), P6 (P6X), P5, P4, P2

 

The main application: 

 

Single row angular contact ball bearings: 

machine tool spindles, high frequency motors, gas turbines , centrifuges, small car front wheel , differential pinion shaft , booster pumps, drilling platforms, food machinery, dividing head, fill welding , low-noise cooling tower , electrical and mechanical equipment, painting equipment , machine slot board , arc welding machine

 

Double row angular contact ball bearings: 

pump, blower , air compressor , various types of transmission , fuel injection pump , printing machinery , planetary reducer, extraction equipment , cycloid reducer , food packaging machinery , welding machines, electric irons, square box , gravity gun , wire strippers , axle, test analysis equipment , chemical machinery
