Brief introduction
Thrust roller bearings are separable bearings, can only withstand axial load and a slight impact, to limit the shaft (or shell) of the axial displacement in one direction, it can be used as single-axis to the position. But its carrying capacity is far greater than the thrust ball bearings.
The single direction thrust ball bearing 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.
The types: bearings with a flat seat surface on the housing washer, bearings with a sphered seat surface and bearings with a
sphered housing washer can be used together with a sphered seat washer
