The sealing device of the bearing unit should be intact and undamaged. After conducting grease leakage, temperature rise, and anti sediment performance tests, the grease leakage rate of the bearing unit should not exceed 10%. At room temperature of 25 ℃, the temperature rise should not exceed 65 ℃.
Product advantages:
1. According to the worst-case working conditions of the vehicle model used, optimize the internal design of the bearings;
2. The inner ring, outer ring, and steel ball are all processed with high-purity special high-quality bearing steel;
3. The cage is made of engineering plastics that comply with YB/T6638, and its technical conditions are in accordance with the provisions of JB/T7048; Or negotiate with the user to use other materials for manufacturing;
4. Generally, the optimal composite sealing structure is used, and the sealing ring material is high-quality nitrile rubber and SPCC skeleton. Other types of rubber can also be used according to special needs; 5. Special lubricating grease customized for special working conditions of wheel hub bearings is added to meet maintenance free requirements.
