Introduce
Trailer hub oil seals are situated between the hub and bearings to prevent lubricating oil or grease from leaking and dust, moisture, and pollutants from entering the wheel hub and bearing system. Made from rubber or a rubber composite material, the seal has high wear resistance and flexibility. An annular or lip design is used to seal the bearing and hub efficiently.
Advantage
1. Material Quality:
Most trailer hub oil seals are made from high-quality materials that meet or exceed OEM specifications. This ensures durability and reliability in a wide range of operating conditions.
2. Design:
Many seals feature a double-lip design that enhances sealing capabilities by providing an additional barrier against contaminants such as dust and water. This design helps maintain the integrity of the lubricant within the hub.
3. Compatibility:
These seals are available in a variety of sizes and specifications, making them compatible with a wide range of trailer axle types, including axles rated from 3,500 lbs to 10,000 lbs. Specific part numbers (e.g., STM373-0223, K71-387-00) help identify replacements that fit different models.
4. Performance Under Pressure:
Seals work effectively under pressure, helping to maintain a positive pressure within the hub cavity. This prevents water ingress during wet conditions, such as when launching or recovering a trailer.
