Frequently Asked Questions

Q: How do I choose the correct size for my tractor shaft oil seal?

You should measure the inner diameter (shaft size), outer diameter (housing size), and the width of the seal. You can also refer to the OEM number in our catalog for an exact match.

Q: What is the benefit of the metal ring in your rubber seals?

The metal ring provides necessary structural rigidity, ensuring the seal remains seated firmly in the hub and resists deformation under high pressure.

Q: Are these seals compatible with high-pressure hydraulic systems?

While these are hub oil seals, we also offer specialized High Pressure Oil Seals and Hydraulic Seal Kits specifically designed for high-pressure environments.

Q: Can you manufacture seals based on custom drawings?

Yes, we provide customized manufacturing services. Please provide your detailed dimensions and material requirements for a tailored quote.

Q: What materials are available for extreme temperature applications?

For extreme temperatures, we recommend NBR+PTFE or HNBR compounds, which offer superior thermal stability compared to standard rubber.

Q: What is the typical lead time for an order of 100 pieces?

For standard sizes in our catalog, we usually ship within 3-7 business days. Custom sizes may require a longer production window.
