Product Description

Four Point Angular Contact Ball Bearing QJ211MA

1) Instruction of Angular Contact Ball Bearing
Angular contact ball bearing can both endure radial load and axial load, what's more, the more axial load, the much higher limited speed. The axial load of this kind of bearing is determined by tangent angle, the bigger tangent angle is, the more capacity of axial load will be.
Demek suppliers various of angular contact ball bearing to meet the
different requirement.

Four-point contact ball bearings

This type of bearings is separable bearings. Their contact angles are same as 35°. When received no load or pure radial load, the steel balls of the ball bearing contact with the four points of the rings. When it is received a pure axial load, the steel balls perform a two-point contact with the ring. In addition, besides the axial load from both directions, this kindly of bearing can take torque-load as well

2) Contact Angle
C = 15 DEG
AC = 25 DEG
B = 40 DEG

4) Features of Single Row 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.
