Thrust ball bearing axial load

The thrust ball bearing adopts a design that can withstand thrust loads during high-speed operation.And is composed of a washer shaped ring with a rolling groove for the ball. This type bearing axial loads, but cannot withstand radial loads. Divided into unidirectional and bidirectional according to the force situation.Unidirectional thrust ball bearings can withstand unidirectional axial loads. Bidirectional thrust ball bearings can withstand bidirectional axial loads,where the shaft ring is matched with the shaft.The installation surface of the seat ring is a spherical bearing with self-aligning performance.Which can reduce the impact of installation errors.

Application: Only suitable for parts that bearing axial load on one side and have low rotational speed, such as crane hooks, vertical water pumps, vertical centrifuges, jacks, low-speed reducers, etc.

Thrust roller bearing axial load

Bearing axial and radial combined loads mainly, but the radial load shall not exceed 55% of the axial load.
The stick of the 29000 type bearing is an asymmetric spherical roller.Which can reduce the relative sliding between the roller and raceway during operation.The roller is longer and larger diameter,more high load capacity.
80000 type thrust cylindrical roller bearings, 90000 type thrust tapered roller bearings, and AXK type thrust needle roller bearings can withstand unidirectional axial loads. They have much greater axial load capacity than thrust ball bearings, and are more rigid with less axial space occupation.

Thrust cylindrical roller bearings and thrust tapered roller bearings are suitable for low-speed applications, with thrust tapered roller bearings having slightly higher speeds than thrust cylindrical roller bearings. Thrust cylindrical roller bearings are separable bearings that can only withstand unidirectional axial loads and slight impacts.And can limit the axial displacement of the shaft (or housing) in one direction.Therefore, they can be used for unidirectional axial positioning.But its load-bearing capacity is much greater than thrust ball bearings.When the roller rolls,due to the different linear velocities at both ends of the roller, the roller inevitably slides on the raceway of the ring. Therefore, the maximum speed of this type of bearing is lower than thrust ball bearings, and it is usually only suitable for low-speed operation.
