QJ 215 Angular Contact Ball Bearing

QJ 215 Angular contact ball bearing

There are three pairs of angular contact ball bearings different configuration type:

A>. back-to-back configuration, code-named DB (70000/DB),

this configuration of steel better withstand the overturning moment of performance, the bearings can withstand two-way axial load;

B>face-to-face configuration, rear codenamed DF (70000/DF),

the rigidity of this configuration and the ability to withstand the overturning moment as good as DB configuration form, the bearings can withstand two-way axial load;

C> tandem configuration, rear codenamed DT (such as 70000/DT),

this configuration can also be connected in series in the same supporting three or more bearings, but can only afford a single direction axis to load.

Generally, in order to balance and limit the axial displacement of the shaft, another support at the need to install the other direction of axial load bearing can withstand.

Angular contact ball bearings features :
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.

Angular contact bearing applications :
electric motors, automotive applications, home appliances, industrial equipment.
