Angular Contact Ball Bearing 3208 ATN9
Ball bearing 3208 ATN9 Profile
Double row bearings can withstand greater radial load mainly radial and axial joint load and torque load limit both the axial displacement of the shaft.The main components used to limit the bi-axial displacement of the shaft and housing.
Such as: contact ball bearings double row angular contact ball bearings, single-row design with two back-to-back arrangement is similar to, but slightly narrower width than two single row bearings. Better rigidity than single row bearings.

1)Single row and combined angular contact ball bearing
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
