Angular contact ball bearing

 1.Anglular contact ball bearing steel balls and inside and outside the points of contact with the circle attachment radial into a point of view. Contact Angle generally divided into 15 °, 30 °, 40 °, respectively for the letter C, A, B says, brand special production contact Angle for 25 ° of these bearings, with the A5 said. Angle contact ball bearing main bear big one-way axial load, the greater the contact Angle, the greater the ability to bear a heavy load. Maintains a material with a steel, brass or engineering plastic, forming a way to have a press or turning, depending on the bearings form or conditions of use different and choose. There are other combined angular contact ball bearing, double row angular contact ball bearing and four-point contact ball bearing.

2.Angle contact ball bearings are widely used in mechanical industry,like in various machinery such as metallurgic machinery,mining machinery,paper making machinery,exile machinery,etc.

Angular contact ball bearing include:
1) Single row angular contact ball bearing
2) Matched angular contact ball bearing
3) Double row angular contact ball bearing
4) Four-point contact ball bearing

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.
