Signs of Worn or Damaged Hub Seals

Conclusion

In mechanical systems, dust seals are frequently found in areas such as wheels, bearings, and hydraulic cylinders. Their design usually features a lip or flange that creates a barrier against particulate matter. By keeping contaminants at bay, dust seals help maintain the integrity of moving parts, extending their lifespan and reducing maintenance costs.

2. Low Maintenance These pumps have few moving parts, which translates to lower maintenance costs and a higher lifespan. Regular maintenance may only include checking for clogs or replacing worn-out parts, making them an ideal solution for remote areas.

The designation 20x35x7 refers to the dimensions of the oil seal. The numbers represent the inner diameter (20 mm), outer diameter (35 mm), and the thickness (7 mm) of the seal. The design of an oil seal is critical, as it must fit precisely to ensure a proper seal and prevent the ingress of dirt, dust, or moisture. The choice of material used for these seals often includes rubber compounds that enhance flexibility and resilience. Common materials include nitrile rubber (NBR), fluorocarbon rubber (FKM), and silicone, each chosen based on the specific application and operating conditions.
