Stainless steel NSK NTN KMY thrust roller bearing 50TP121 all kinds of thrust ro

Thrust Roller Bearing can be divided into 2 kinds, one is for Single Direction Trust Roller Bearing & another is for Double Direction Trust Roller Bearing.  

single direction thrust ball bearings consist of a shaft washer, a housing washer and a ball and cage thrust assembly. The bearings are separable so that mounting is simple as the washers and the ball and cage assembly can be mounted separately. 
Smaller sizes are available with either a flat seat surface on the housing washer or a sphered seat surface. Bearings with a sphered housing washer can be used together with a sphered seat washer to compensate for misalignment between the support surface in the housing and the shaft. 
Single direction thrust ball bearings, as their name suggests, can accommodate axial loads in one direction and thus locate a shaft axially in one direction. They must not be subjected to any radial load. 
double direction thrust ball bearings consist of one shaft washer, two housing washers and two ball and cage thrust assemblies. The bearings are separable so that mounting is simple. The various parts can be mounted separately. The housing washers and ball and cage thrust assemblies are identical to those of the single direction bearings. 
Smaller bearings are available with either a flat seat surface on the housing washers or with a sphered seat surface. Bearings with sphered housing washers can be used together with sphered seat washers to compensate for misalignment between the housing and shaft. 
Double direction thrust ball bearings can accommodate axial loads acting in both directions and can thus serve to axially locate a shaft in both directions. They must not be subjected to radial load.

Product Description

The rollers of these bearing are of spherical shape, and the spherical raceway surface of the housing washer is selfaligned. These bearing are featured by the extremely big axial load carrying capacity and meanwhile they can also carry cetrain radial load. Oil lubrication is commonly used while working. Applications of these bearings can be found in hydroelectric generators, vertical notors, propeller axle of vessels, tower cranes and squeezing presses.
