High-performance loader hub seals
Precision sealing solutions designed for construction machinery reduce equipment maintenance costs and extend hub life
Why are loader hub seals critical?
When the loader is operating in high-load scenarios such as mines and construction sites, the wheel hub needs to withstand severe vibration, sediment intrusion, and high-pressure impact. Poor quality seals can lead to oil leakage, bearing wear, and even equipment downtime. Our rubber hub seals are designed for extreme service conditions using a combination of specialty nitrile rubber (NBR) and fluoroelastomer (FKM) and offer three core values:
Super sealing: multi-layer lip structure Spring-reinforced design ensures dynamic seal stability and prevents oil leakage and contaminant ingress.
Resistant to extreme environments: Resistant to temperatures ranging from -40°C to 150°C, hydraulic oils, acids and alkali media, and UV aging.
Reduce operation and maintenance costs: The average service life is more than 5,000 hours, reducing the frequency of equipment shutdown and replacement.
