  Angular Contact Ball Bearing  

 1.High precision 
2.Wide range of use 
3.Open bearing 

Angular contact ball bearings  are able to support radial load and axial load. As single row angular contact ball bearings can only support axial load in single direction, matched bearing mounting is often adopted to them. As matched pair of bearings, preload for them is more convenient. Retainer are made of brass, synthetic resins or others subject to individual bearing features and application conditions.

Angular contact ball bearing main purposes:

Single row angular contact ball bearings: machine tool spindles, high frequency motors, gas turbines, centrifuges, small car front, differential pinion shaft

Double row angular contact ball bearings: oil pump, Roots blower, air compressor, various types of transmission, fuel injection pumps, printing machine

Introduction:

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.

The axial load carrying capacity of angular contact ball bearings increases with increasing contact angle. The contact angle α is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane, along which the load is transmitted from one raceway to another, and a line perpendicular to the bearing axis 

Applications:

  • Suitable for very high rotating speeds

 •Well suited for medium high radial and axial loads in one or both directions

 •Various seals and grease variants available for different operating conditions

 •Numerous clearance and tolerance classes available for different operating conditions

 •Application examples: electrical motors, general machinery, industrial gearboxes, pumps,agricultural machinery, etc.

2: Angular contact ball bearings description:

Basic Design:

Angular contact ball bearings are self retaining units which consist of solid inner and outer rings, and ball &cage assemblies.

The bearings have raceways in the inner and outer rings that are displaced with respect to each other in the direction of the bearing axis,

 and are designed to accommodate combined loads, ie. simultaneously acting radial and axial loads.

Detailed Description:

Series :7000C,7200,7300C and so on
