The TCN oil seal is constructed from a compound known as nitrile rubber (NBR), which is known for its excellent resistance to petroleum-based oils, fuels, and other chemicals. The triple-chamber design of the TCN seal/contains three distinct sealing lips that enhance its ability to maintain a tight seal, thereby preventing fluid leakage and protecting machinery components from contaminants.

2. Back-up rings These are placed alongside O-rings to provide additional support, preventing the O-ring from extruding under pressure. This is particularly important in high-pressure applications.

4. Low Friction Advanced designs and materials reduce frictional wear, enhancing performance and longevity, which is critical in maximizing efficiency and reducing maintenance costs.

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.
