1,Single row angular contact ball bearing; 2,Double row angular contact ball bearing; 3,Four point contact ball bearing;

Angular contact ball bearing with contact angle is applicable to high speed and high precision rotary, which can bear combined load.

1,Single row and combined angular contact ball bearing

Standard contact angle is 150,250 and 400 respectively configuring in post position with code "C","AC"and"B".

The more contact angle is, the larger axial load bearing capacity is,the smaller contact surface is,themuch more convenient high speed rotary is.

Pretension is made on angular contact ball bearing to increase rididity and accuracy of bearing.

This bearing creates axial thrust load when being forced by radial load,thus it is configured(or combined) face to face or back to back.

2,Double row angular contact ball bearing

Double row angular contact ball bearing can be subinitted radial and acial louding limit speed is quite high, it is non-separated type of bearing has high rigid can be submitted doubk direetion of axial load,the bearing could apply with the four row cylindrical bearing together to limit the working roll to move in axial diretion the double row angular contact ball bearing could apply with other bearings as a position bearing.

3,Four point contact ball bearing

Standard structure is that its inner ring is equally divided in axial direction,which is applicable to axial load or combined load,among which acial load is major composition.

Single bearing can bear double row axial load and certain extent radial load.According to different direction of axial load,ring and sphere always contact at two points of linear line.
