2. Keep Contaminants Out Dust, dirt, and other foreign particles can cause severe damage to machinery. Oil seals act as barriers, keeping these contaminants from entering and prolonging the life of the equipment.

The performance of high pressure hydraulic shaft seals largely depends on the materials used in their construction. Common materials include nitrile rubber (NBR), fluorocarbon (FKM), polyurethane (PU), and PTFE (Teflon). Each material has unique properties that make it suitable for specific temperature ranges, chemical exposures, and pressure levels.

Routine inspections are vital for ensuring that wheel oil seals are functioning correctly. Drivers should look for signs of leakage around the wheel hubs, as well as potential issues such as uneven wear on tires, as these could indicate failing seals. A thorough maintenance routine should include regular check-ups by a qualified mechanic, particularly if the vehicle is often driven under severe conditions.

Hub oil seals can wear out over time due to various factors, including age, temperature variations, and mechanical stress. Signs of a failing oil seal may include oil leaks, unusual noises from the wheel hub, or the presence of contaminants inside the hub assembly. Regular inspections are essential, especially during routine maintenance checks, to identify any potential issues before they escalate.
