81109 E M Cylindrical Roller Thrust Bearing Dimensions

Thrust roller bearings are used to bear the combined axial and radial load, which is mainly the axial load, but the radial load shall not exceed 55% of the axial load. This kind of bearing has low friction factor, high speed, and has self-aligning performance.

The rollers of type 29000 bearings are asymmetrical spherical rollers, which can reduce the relative sliding of the rollers and raceways during operation. The rollers are long and large in diameter, with a large number of rollers and high load capacity. They are usually lubricated by oil. , Grease lubrication can be used in individual low speed situations.

Type 80000 thrust cylindrical roller bearings, type 90000 thrust tapered roller bearings and AXK type thrust needle roller bearings can withstand one-way axial load. It has a much larger axial load capacity than thrust ball bearings, and has greater rigidity. Occupies little axial space.

Thrust cylindrical roller bearings and thrust tapered roller bearings are suitable for low speed occasions, thrust tapered roller bearings have a slightly higher speed than thrust cylindrical roller bearings.

Thrust cylindrical roller bearings are mainly used in machinery such as heavy-duty machine tools, high-power marine gearboxes, oil drilling rigs, and vertical motors.
