In addition to preventing the ingress of contaminants, dust lip seals also play a role in retaining lubricants within the system. Lubricants such as oil and grease are essential for reducing friction and wear between moving parts, helping to extend the lifespan of the equipment. Without an effective seal in place, these lubricants can leak out of the system, leading to insufficient lubrication and potential damage to the machinery. Dust lip seals help to maintain the proper levels of lubricant within the system, ensuring optimal performance and minimizing the risk of failure.

The choice of seal size depends on various factors. The pressure rating of the seal is a significant consideration, as higher pressure systems require seals with larger cross-sections to withstand the forces The pressure rating of the seal is a significant consideration, as higher pressure systems require seals with larger cross-sections to withstand the forces

hydraulic oil seal sizes. The speed of the system also impacts the selection; faster-moving components may need wider seals to manage heat generation effectively. Additionally, the type of fluid, temperature range, and environmental conditions must be taken into account.


The primary function of axle hub seals is to retain lubrication. Proper lubrication is essential for the smooth operation of moving parts, reducing friction and wear. Without effective sealing, the lubricant can leak out, leading to inadequate lubrication of the gears and bearings, which may cause premature wear and eventual failure of the components.
