Product introduction

A thrust ball bearing is a bearing that can rotate smoothly while bearing an axial load (the same load in the longitudinal direction as the rotating shaft). It is mainly used to bear axial forces and cannot bear radial loads. The following is a detailed introduction about thrust ball bearings：

Structural composition：

Seat：Cooperate with the shell to support and fix.

Shaft ring：In conjunction with the shaft, it is used to transmit axial force.

Ball cage assembly：The cage evenly divides the steel balls, allowing them to roll in an orderly manner during operation, reducing friction and collision between the steel balls, and improving the operating efficiency and service life of the bearing.

According to the force：

Unidirectional thrust ball bearing：It can withstand unidirectional axial loads, that is, it can only withstand axial forces in one direction.

Bidirectional thrust ball bearing：It can withstand bidirectional axial loads and consists of two rows of rolling elements and three washers, but due to the corresponding increase in thickness, it is necessary to ensure assembly space.

According to the shape of the seat ring mounting surface：

Flat bottom seat cushion type：The mounting surface of the seat ring is flat.

Self-aligning spherical seat cushion type：The mounting surface of the seat ring is spherical, with self-aligning performance, which can reduce the influence of installation errors, and ensure the normal operation of the bearing even if there is a certain angular deviation or shaft deflection during installation.

Feature：

Can withstand high axial loads：Due to its special structural design, thrust ball bearings can withstand large axial forces, but they are less capable of bearing radial loads.

Lower limit speed：When rotating at high speed, the friction between the steel ball and the raceway generates greater heat and wear, so thrust ball bearings are usually suitable for applications with relatively low rotational speeds.

Available in one-way and two-way types：To meet the requirements of different axial load directions.

Has good self-aligning properties (some types)：For example, the self-aligning spherical seat cushion type can adapt to the installation error and angular deviation between the shaft and the shell to a certain extent, ensuring the normal operation of the bearing and reducing the impact of installation accuracy on the bearing performance.

Using high-quality steel and advanced grease technology：High-quality steel can extend bearing life, high-grade grease technology can extend grease life and improve bearing performance, and high-grade steel balls make high-speed rotation quiet and smooth.

Application field：

It is suitable for parts that bear axial load on one side and low speed：Such as crane hooks, vertical pumps, vertical centrifuges, jacks, low-speed reducers, etc. In these equipment, thrust ball bearings are mainly used to withstand the axial force generated when the equipment is working to ensure the normal operation of the equipment.

In the field of machine tools：The spindle of some machine tools will use thrust ball bearings, such as numerical control lathes, milling machines, machining centers, etc. When drilling the center of the workpiece, the thrust direction of the spindle will be subject to high load. By installing thrust ball bearings, the axial displacement of the spindle can be minimized to ensure machining accuracy.

In household appliances：For example, refrigerators, vacuum cleaners, printer peripherals, fishing wheels, etc. also use thrust ball bearings to withstand axial forces in a specific direction to meet the working requirements of the equipment.
