Oil Seal Of Rear Wheel Hub Of Sany Concrete Mixer 185 * 210 * 22

The rear wheel hub oil seal (185*210*22), with factory codes 61021991 and 610219912, is a vital component of the SANY concrete mixer truck's rear wheel hub assembly. Its main functions include:

1. Sealing Lubricants:
   The oil seal ensures that lubricants, such as oil or grease, remain inside the wheel hub assembly. This helps to reduce friction and wear on the wheel bearings, ensuring smooth and efficient operation.

2. Preventing Contaminant Ingress:
   It prevents external contaminants such as dirt, dust, water, and mud from entering the wheel hub, which could otherwise cause damage to the bearings and other internal components.

3. Maintaining Wheel Hub Integrity:
   By providing a reliable seal, the oil seal protects the wheel hub assembly, ensuring its proper functionality and performance under various working conditions.

4. Extending Component Lifespan:
   The oil seal reduces wear and tear on the wheel hub and bearings, prolonging their service life and minimizing the risk of premature failures.

5. Reducing Maintenance Costs:
   By maintaining proper sealing and protection, the oil seal lowers the frequency of maintenance and repair needs, contributing to cost savings in vehicle operation.
