Description: 

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.

 

It also can bear pure axial load. Its axial load capacity depends on the contact angle which can increase accordingly. It can be used for high speed and high precision application due to high limit speed and pre-adjustable rigidity.

 

 

 

Features:

1) Quality standards: ABEC1, ABEC3,ABEC5,ABEC7

Able to accommodate both radial and thrust loads

Suitable for high speed operation

Open and sealed versions available

Highly rigid

 

2) Extensively used in: 

 Machine tool main shafts

 Mill grinding wheel shafts

 Internal-combustion engine liquid gear boxes

 Worm reduction gears

 Electric drillers

 Centrifugal machines

 Pressure boosters

 

3) Dimensions: bore from 10 to 240mm

4) Inner packing: 1pc/box, 5 or 10pcs/plastic tube or plastic bag
