Thust ball bearing:

SKF 51109 BEARING single-direction thrust ball bearings including a shaft washer, a seat and a steel ball cage assembly.

The bearing is a separate type, shaft ring, seat ring, steel balls - cage assembly can be installed separately,easy for installation.

There are also smaller dimensions of the bearing, a bearing ring with a flat bottom cushion, and another shape is a spherical seat cushion.

The seat of the spherical bearing can be used together with the spherical seat cushion to the misalignment between the compensation of the bearing surface of the bearing seat and the shaft.

In order to provide satisfactory operation performance,like  all ball and roller bearings, thrust ball bearings must have a given minimum load, especially under conditions of  high speed, high acceleration, or the direction of the load change rapidly. In such a case, the inertial force of the ball and cage, and friction where the lubricant will scroll state of the bearing adversely affect, and may lead to appear sufficient to cause damage to the sliding between the ball and raceway.

This type bearing is suitable for :

Railway vehicle axles, motors, appliances, machinery and equipment, machine tool spindle, generators, grinding coal machine, extruder, forming machine, rolling mill roll neck and deceleration devices, construction machinery
