  • Description

Introduction:

Thrust roller bearings are used to support axial and radial combined loads that are mainly axial loads, but the radial load must not exceed 55% of the axial load. Compared with other thrust roller bearings, this type of bearing has a lower friction coefficient, higher speed and self-aligning performance

 

Product Features:

    It is used to support the axial and radial combined load mainly composed of axial load, but the radial load must not exceed 55% of the axial load. Compared with other thrust roller bearings, this type of bearing has a lower friction factor, higher speed, and self-aligning performance.

The 29000 type bearing stick is an asymmetric spherical roller, which can reduce the relative sliding of the roller and the raceway in the work, and the roller is long, the diameter is large, the number of rollers is large, and the load capacity is high. Usually oil lubrication Individual low-speed situations can be greased. When designing and selecting, it should be preferred;

80000 thrust cylindrical roller bearings, 90000 thrust tapered roller bearings and AXK thrust needle bearings can withstand unidirectional axial load, it has much greater axial load capacity than thrust ball bearings, and has greater rigidity Takes up little axial space.

Thrust cylindrical roller bearings and thrust tapered roller bearings are suitable for occasions with low speed. Thrust tapered roller bearings have a slightly higher speed than thrust cylindrical roller bearings. Thrust cylindrical roller bearings are separable bearings that can only withstand unidirectional axial loads and slight impacts. They can limit the axial displacement of the shaft (or housing) in one direction, so they can be used as unidirectional axial positioning. But its bearing capacity is far greater than thrust ball bearings. When the roller is rolling, due to the different linear speeds of the two ends of the roller, the roller inevitably slips on the raceway of the ring. Therefore, the limit speed of this type of bearing is lower than that of thrust ball bearings, and it is usually only suitable for low-speed operation.

The thrust cylindrical roller bearing of standard design adopts the metal solid cage of the car. According to the requirements of the user, other types or materials of the cage can also be adopted. Thrust tapered roller bearings can only withstand unidirectional axial loads and can limit the unidirectional axial displacement of the bearings, so they can be used as unidirectional axial positioning. Compared with thrust cylindrical roller bearings, the bearing capacity is large and the relative sliding is small, but the limiting speed is low.

 

Product Usage:

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