Angular contact ball bearings have raceways in the inner and outer rings that are displaced with respect to each other in the direction of the bearing axis. This means that they are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads.

 

It also can bear pure axial load. Its axial load capacity depends on the contact angle which can increase accordingly. It can be used for high speed and high precision application due to high limit speed and pre-adjustable rigidity.

 

Bearing types:  

 

  Single row angular contact ball bearings: 7000, 7200, 7300, 719,718 ,B70,B72,B719,B718,H719,H718,Series

  Four point angular contact ball bearings: QJ series

  Double row angular contact ball bearings: 3200, 3300 series

  Suffix: A, B, C, DB, DF, DT

 

DB : Two bearings matched back-to-back 

DF : Two bearings matched face-to-face 

DT : Two bearings matched in tandem 

B : 40° contact angle 

C : 15°contact angle  

AC :25°contact angle 

CB : Bearing for universal matching. Two bearings arranged back-to-back or face-to-face will have a Normal axial internal clearance before mounting
