Introduction of Thrust Roller Bearing

 

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

· This type bearing 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.

 

Application

 

Thrust roller bearings are mainly used for heavy-duty machine tools, power marine gear boxes, oil rig, electrical and other machinery in the vertical.
