Rolling bearings can be classified into the following main categories based on the type and quantity of rolling elements:
1. Deep groove ball bearing: Deep groove ball bearing is the most common type of bearing, and its rolling element is spherical roller, which is divided into two types: single row deep groove ball bearing and double row deep groove ball bearing. Suitable for bearing radial and axial bidirectional loads.
2. Angular contact ball bearing: The rolling element of the angular contact ball bearing is a spherical roller, which has a relatively large contact angle with the inner and outer rings and can withstand radial and axial bidirectional loads. Common types include unidirectional angular contact ball bearings and bidirectional angular contact ball bearings.
3. Cylindrical roller bearings: The rolling element of cylindrical roller bearings is cylindrical rollers, which are divided into single row cylindrical roller bearings and double row cylindrical roller bearings. Capable of withstanding large radial and axial loads.
4. Self aligning roller bearing: The rolling element of the self aligning roller bearing is cylindrical or conical roller, which has self aligning function and can automatically adjust the tilt between the bearing and the shaft. It is suitable for bearing large radial and axial loads as well as axial deflection.
5. Cone roller bearing: The rolling element of the cone roller bearing is a conical roller, which has a large contact angle and can withstand large radial and axial loads. It is suitable for situations where high load capacity is required in both radial and axial directions.
6. Needle roller bearing: The rolling element of the needle roller bearing is a needle roller, which has a large length and is suitable for bearing large radial loads and confined spaces.
7. Thrust ball bearing: The rolling element of the thrust ball bearing is a spherical roller, which can withstand unidirectional or bidirectional axial loads, but has a relatively small bearing capacity for radial loads.
8. Thrust roller bearing: The rolling element of the thrust roller bearing is a cylindrical roller, which can withstand large axial loads and is suitable for situations where large loads need to be borne axially.
These are common classifications of rolling bearings, and selecting the appropriate bearing type based on different working requirements and load conditions can effectively meet the requirements of the equipment.
