Four-point Angular Contact Bearing
Four-point Angular contact ball bearing:
Four-point 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.
Advantages :
Ultra clean steel to extend bearing life by up to 80%
Advanced grade technology
Quiet and smooth operation even at high speed
Super finished raceways
Offer products in 15,25 and 40 degree angles
Available in arrange of Polyamide, steel and brass cage assembles
Application:
Application: Angular Contact Ball Bearing is widely used in cars, compressors, construction, electric motors, food industry, home appliances etc. As a rolling element, it turns the world.
