Whell bearing SNR angular contact ball bearing 7201

Single row angular contact ball bearings are self-retaining units with solid inner and outer rings and ball and cage assemblies with polyamide, sheet metal or brass cages. The raceways of the inner and outer rings are offset from each other along the bearing axis. The bearings are available in open and sealed designs. Their angular adjustment facility is very limited.

Single row angular contact ball bearings can support axial forces in one direction and high radial forces. They must be axially adjusted against a second bearing fitted in a mirror image arrangement

Description of the bearing:

1)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.

2)The axial load carrying capacity of angular contact ball bearings increases with increasing contact angle

3)cageof the bearing: polyamide, sheet steel or brass cages.

4)The bearings are available in open and sealed versions

5)Four-point contact ball bearings are radial single row angular contact ball bearings with raceways that are designed to support axial loads acting in both directions. Radial loads can be supported up to a certain fraction of the axial load. These bearings take up considerably less axial space than double row bearings.

6)Separable design the outer ring with ball and cage assembly can be mounted separately from the two inner ring halves.

Applications:

Single row: machine tool spindle,  high frequency motor, gas turbine, centrifuge, differential pinion-shaft, small cars'  front wheel, etc. 

Double row: oil pump, roots blower, air compressor, all kinds of transmission gearbox, fuel injection pump, printing machinery, etc.
