Classification of bearings

According to the structural form and use, bearings can be divided into the following categories:
According to the shape of the rolling body classification: ball bearing: by the inner ring, outer ring, steel ball and cage composition. It is suitable for high speed, low friction and high precision.
Tapered roller bearings: the inner and outer rings are conical, suitable for large radial and axial loads. Cylindrical roller bearings: The inner and outer rings are cylindrical, suitable for applications with large radial loads and high speeds.
Needle roller bearing: the rolling body is a long strip, suitable for limited space, limited axial space and need to bear large axial load occasions.
According to the type of load: radial bearings: mainly bear radial forces, such as ball bearings and cylindrical roller bearings.

Axial bearings: mainly bear axial forces, such as thrust ball bearings and thrust roller bearings. Radial axial bearing: can withstand both radial and axial forces, such as tapered roller bearings.
Classification by use:
Automotive bearings: used in automotive engine, transmission, suspension system and steering system. Machine tool bearings: used for machine tool spindle, feed system and slide table.
Metallurgical bearing: used in rolling mill, continuous casting machine, high pressure water pump and other metallurgical equipment.
Aerospace bearings: Used in aircraft, missiles, rockets and other aerospace fields. Motor bearings: Used for electrical equipment such as motors, generators and power tools.
The above are some basic classifications of bearings, and it is very important to choose the appropriate bearing type according to the specific application needs and working environment.
