The main function of the bearing (hub bearing) is to support the load and provide precise guidance for the rotation of the hub. It bears both axial load and radial load, and is a very important component. Automobile bearings are a faction derived from the classification of bearings according to their purpose. They are a large part of the bearing industry. They have the function of keeping the shock absorber rotating with the wheels when the vehicle is turning, and preventing the vibration from being transmitted through the shock absorber due to uneven road surfaces when the car is running. To the body and so on.

Bearing application and performance characteristics
Although the automobile bearing is a small part, it is closely related to the reliability, safety and comfort of the vehicle.
Bearings have an important impact on the performance of the entire vehicle. In terms of reliability, once damaged, it will affect the driving of the entire vehicle. In terms of safety, the installation position of some bearings is very important, such as wheel hub bearings, which support the weight of the entire vehicle. Once a failure occurs, the safety of the entire vehicle will be affected. In terms of comfort, bearings are not only closely related to the smooth running of the vehicle, but bearings of poor quality are also prone to generate louder noise.
Hub Bearings from POETRY SPINT:
Application features:
1. The periphery of the bearing is full of moisture and dust;
2. Bearings are often in contact with mud;
3. The bearing will be used in high temperature and high cold areas;
4. Automobile wheel hub bearings are double-row angular contact ball bearings, which have the characteristics of double-row angular contact ball bearings. Generally, they adopt a double-half inner ring structure with a large base number, which can be assembled and can ensure axial clearance.

Performance requirements:
The sealing device of the bearing unit should be intact. After the grease leakage, temperature rise, and anti-sand performance tests, the grease leakage rate of the bearing unit should not exceed 10%, and the temperature rise should not exceed 65°C at room temperature of 25°C.
Product advantages :
1. According to the worst working conditions of the vehicle used, internal optimization design of the bearing is carried out;
2. The inner ring, outer ring and steel balls are all processed with high-purity special high-quality bearing steel;
3. The cage is made of engineering plastics conforming to YB/T6638, and its technical conditions are in accordance with the provisions of JB/T7048; or it is made of other materials in consultation with the user;
4. Generally, the optimal composite sealing structure is adopted, and the sealing ring material is made of high-quality nitrile rubber and SPCC framework, and other types of rubber can be used according to special needs; 5. The bearing is added as a special lubricating grease customized for the special working conditions of the hub bearing to meet the requirements of exemption. Maintenance requirements.
