Thrust bearings are mainly divided into two categories: thrust ball bearings and thrust roller bearings.
Thrust ball bearings are divided into thrust ball bearings and thrust angular contact ball bearings. The raceway ring that matches the shaft is called the shaft ring, and the raceway ring that matches the shell is called the seat ring. The two-way bearing matches the middle ring with the shaft. One-way bearings can bear one-way axial load, and two-way bearings can bear two-way axial load. Bearings with a spherical mounting surface of the seat ring have self-aligning performance, which can reduce the impact of installation errors. This type of bearing is mainly used in automobile steering mechanisms and machine tool spindles.
Thrust roller bearings are divided into thrust cylindrical roller bearings, thrust spherical roller bearings, thrust tapered roller bearings, and thrust needle roller bearings. Among them, thrust cylindrical roller bearings are mainly used in oil drilling rigs, iron and steel making machinery; thrust spherical roller bearings are used in hydroelectric generators, vertical motors, ship propeller shafts, tower cranes, extruders, etc.; and thrust spherical roller bearings Tapered roller bearings are mostly used to bear axial loads in one direction, such as crane hooks and oil drilling rig swivels; while bidirectional bearings are suitable for bearing bidirectional axial loads, such as roll necks of steel rolling mills.
Bearings in these classifications have their own unique characteristics and applications. The main difference lies in their structure and design, which determines the type, magnitude and direction of loads they can withstand, as well as the rotation speeds and working environments they adapt to.
Thrust ball bearings: This kind of bearing is mainly suitable for bearing one-way axial force, such as in automobile steering mechanisms and machine tool spindles. Because of its simple design, it is generally suitable for low- and medium-speed applications.
Thrust roller bearings: There are different specific types of these bearings, each with its own special application. For example, thrust cylindrical roller bearings are suitable for situations where large loads and low rotational speeds are required, such as oil drilling rigs and iron-making machinery. Thrust spherical roller bearings are suitable for equipment that need to withstand large axial forces and overturning moments, such as hydroelectric generators and vertical motors. Thrust tapered roller bearings are suitable for equipment that can withstand unidirectional axial force and large overturning moment, such as crane hooks and oil drilling rig swivels.
Different types of thrust bearings have their own unique characteristics and applications. Choosing the type of bearing suitable for a specific working environment is the key to ensuring the reliability and efficiency of mechanical equipment.
