A thrust bearing is a kind of bearing designed to support axial loads and decrease friction between moving parts. During operation, the moving parts of the machine move with the movement of thrust bearings. The movement of the thrust bearing is designed to permit and support rotation around a fixed axis.
The essential characteristic of thrust bearings is to switch the axial load at the shaft, prevent the shaft from moving axially, and decrease friction between moving parts.
These kinds of bearings are usually mounted around the shaft, but against raised thrust collars. This thrust ring ensures accurate transmission of axial loads from the shaft to the bearings. In most cases, pressure rings are used in pairs and are placed on either side of the pressure collar.

Working Concept of Thrust Bearing
Most of the thrust bearings use balls to support the load. Thrust ball bearings contain a small metal ball in the surrounding band. These types of bearings are used to absorb axial loads. The placement of the balls helps to rotate the moving parts of the machine.
There are many other types of thrust bearings. The cylinder bearing is one of the most famous types of the thrust bearing. These bearings have cylindrical-shaped rollers facing the shaft. The magnetic thrust bearings are not ashamed of their name by creating a magnetic field. They are made of ferromagnetic materials that create a magnetic field. This magnetic field assists to carry axial thrust.
Different Types of Thrust Bearings
- Thrust Ball Bearings
- Thrust Roller Bearing
- Cylindrical Thrust Roller Bearing
- Tapered Roller Thrust Bearing
- Spherical thrust roller bearings
Conclusion
Bearings are used in a variety of machines around the world to support moving parts and reduce friction. Contact between metals causes a lot of friction. Friction increases the wear of the metal and creates a crushed material that slowly degrades the metal. Bearings reduce friction by rotating the two surfaces together, reducing the friction they produce. Thrust bearings are the most well-known type of bearing. These bearings are typically used to support axial loads.
