Thrust Ball Bearing

Hydraulic Pump Bearings 51230 Steel Ball Thrust Bearings 51230M

Descriptions of 51230 bearings

51230 bearings consist of three parts, a shaft and housing washer that have annular grooves in them and a caged ball bearing assembly that is sandwiched in between them. Assembly and mounting is a simple operation as the parts are separate. They support axial loads in one direction. Clearance is provided in the bore of one of the raceways to allow for alignment. 

51230 bearings consist of shaft washer, a housing washer and a ball and cage thrust assembly. They are separable which means that mounting is simple. They can accommodate axial loads in one direction only and must not be subjected to any radial load.

51230 bearings consist of two housing washers, two ball and cage assemblies and one shaft washer. These bearings can handle thrust loads from two directions.

1.  Thrust ball bearing can handle loads in the axial direction only.
2.  Bearing rings mounted on the shaft are called shaft washers, while those mounted in the  housing are called housing washers.
3.  Both washers contain raceways for the balls.
4. Thrust ball bearings are available as both single an bi-directional types. The bi-directional  thrust bearing incorporates a third washer and an additional set of balls.
5.  The center washer is located in axial direction by a shaft shoulder and sleeve.
6.  Care must be taken in handling to prevent damage to separate rings and ball assemblies.
7.  The trust ball bearings are Available in two designs: single direction and double direction.
8.  Material: bearing steel, high chrome, carbon steel, stainless steel, ect.

Lubrication of 51230 bearings 

51230 bearings can be lubricated with oil or grease. Higher speeds can be achieved with oil lubrication. In order to allow oil to flow between the two rows of balls, the housing locating washer has a lubrication groove and lubrication holes.

At high speeds, overlubrication of the radial bearing can be prevented if the installation space is separated between the axial angular contact ball bearing and the cylindrical roller bearing.
