Single direction axial angular contact ball bearings

Single direction axial angular contact ball bearings

Single direction axial angular contact ball bearing is a kind of special bearing mainly used in turntable and rotary drilling machinery. Many large-szie of this bearings are installed on the of oil and gas drilling machinery.
Size range: 292.1 - 1371.6 mm (Inner damension)
Delivery: 30 days

Features 

Single direction axial angular contact ball bearings comprise a shaft locating washer and a housing locating washer, into which raceways are machined, and a cage with balls. Due to the large number of balls, the bearings have high rigidity. The cage is guided on the rib of the housing locating washer. Single direction axial angular contact ball bearings are separable. The bearing washers and the cage can be mounted separately. Single direction axial angular contact ball bearings do not permit angular misalignment or skewing between the shaft and housing. Single direction axial angular contact ball bearings have nonstandardised inch size dimensions and designations (Z-5..ASKL).

Axial and radial load capacity 

In their main application in rotary tables for drilling rigs, two axial angular contact ball bearings are axially adjusted against each other.

The upper bearing with the higher load carrying capacity can support very high axial forces (the weight of the drill string) in one direction. 

The bearings are only suitable for radial loads under certain conditions.


Sealing 

Axial angular contact ball bearings are of an open design.


Lubrication 

Due to the vertical arrangement of the shaft, the single direction axial angular contact ball bearings are lubricated with oil.


Operating temperature 

The single direction axial angular contact ball bearings can be used at operating temperatures from –30 °C to +150 °C.


Cage 

The solid brass cage is guided on the rib of the housing locating 

washer.
