Bearings can be classified based on factors such as their structure, mode of motion, and usage environment. The following are several basic bearing classification methods:
1. Classification by structure:
(1) Deep groove ball bearing: The most common type of bearing, with a simple structure and high load-bearing capacity.
(2) Angular contact ball bearings: suitable for high-speed motion and high-limit load situations, and can also withstand radial loads and certain axial loads.
(3) Tapered roller bearings: mainly used in overload situations, such as mining and metallurgical equipment.
(4) Self aligning ball bearings: suitable for applications with high loads and can withstand axial and radial loads.
2. Classification according to exercise mode:
(1) Radial bearings: mainly bear radial loads, such as deep groove ball bearings, tapered roller bearings, etc.
(2) Axial bearings: mainly bear axial loads, such as needle roller bearings, tapered roller bearings, etc.
(3) Angular contact bearings: withstand radial and axial loads, used for high-speed rotation and compact design applications.
3. Classification by usage environment:
(1) High temperature bearings: Suitable for high-temperature applications, such as hot liquid equipment, industrial metallurgy, etc.
(2) Corrosion resistant bearings: Suitable for bearings in liquid and chemical media, such as food and chemical industries.
(3) Vacuum bearing: suitable for equipment under vacuum conditions, such as semiconductor manufacturing.
In summary, different types of bearings should be used in different mechanical equipment, and selecting the appropriate bearing can better maintain the performance and lifespan of the machine.
