Wheel bearing angular contact ball bearing 7038

Wheel bearing angular contact ball bearing 7038

Product details:

Angular contact ball bearing can carry radial load and axial load at the same time, meanwhile, it can also endure pure axial load, together with high limited speed. The carrying capacity of axial load is decided by the contact angle, the bigger contact angle, the higher carrying capacity of axial load.

Like other bearings, angular contact ball bearings also have lots of structures. Single row angular contact ball bearings can accommodate radial load and axial load in single direction. While double row angular contact ball bearings in DB or DF combination and four-point contact ball bearings can accommodate radial load and axial load in two directions.

Angular contact ball bearing types:

single row angular contact ball bearing

double row angular contact ball bearing

four point angular contact ball bearing

thrust angular contact ball bearing

Important skills index:

(1) Bearing accuracy index: Beyond the GB / 307.1-94 P4 level precision
(2) High-speed performance index : dmN=1.3~1.8x106/min

(3) The use of life:>1500h

High-speed fine angular contact ball bearing use of life have a great relationship with equipment:pls note following:

(1)Install bearing should be in clean room, bearing must through carefully matching, bearing must through the spacer grinding

(2)Clean up before install bearing,

(3)Install bearing should be take special tools

(4) Bearings shall be stored in clean, ventilated, and no erosion of gas

Application:

Angular contact ball bearings suit high-speed rotation and high-precision rotation. These bearings are mainly used in the fields like machine tool spindles high frequency motors, oil pumps, air compressors, and printing machines, etc. Four-point contact ball bearings are mostly used in the roller-boxes of rolling mills to carry axial load.
