Product Description

616628B Double Row Angular Contact Ball Bearing With Flange Size 35x77x22mm Weight 0.46 KGS

Angular contact bearings are able to support radial load and axial load,or just axial load,and can work under high speed.


single row angular contact ball bearings can only support axial load in single direction, in bear radial load,will cause additional axial force,and can only limit the axial displacement of the shaft or housing in one direction.If pairs of double installation,the bearing outer ring relatively wide end face of wide and narrow end facing the narrow end.This can avoid additional axial force,and the shaft or housing to limit the range of the axial clearance in both directions.Angular contact ball bearing was more balls than deep groove ball bearing,so the load bearing capacity is the highest in all ball bearing,and it has strong rigidity,rotate stable.It can also through the inner and outer rings relative displacement on the radial clearance.


Features of angular contact ball bearing:


(1)Angular contact ball bearings are particularly suitable for carrying combined (axial and radial) loads. Sometimes, they also can carry pure axial load and operate in higher speed. Under radial load, axial component force will be produced which must be counteracted. So the bearings are normally adjust against a second bearing.

(2)Single row angular contact ball bearings can carry axial load acting in one direction only. In many applications, angular contact ball bearings in pairs or muti-arrangement should be used. The axial load carrying capacity of angular contact ball bearings increase with the increase of contact angle.

(3)Angular contact ball bearings have raceways in the inner and outer rings that are displaced with respect to each other in the direction of the bearing axis. This means that they are designed to accommodate combined loads, i.e.simultaneously acting radial and axial loads.
