Frequently Asked Questions

Q: What are the benefits of using a Cassette Oil Seal over a standard one?

Cassette seals integrate the seal and the housing into one unit, which simplifies installation and provides superior protection against contaminants compared to standalone rubber seals.

Q: Is NBR the best material for tractor wheel hub seals?

NBR (Nitrile Rubber) is excellent for most automotive and agricultural applications due to its high resistance to oil, fuel, and water, making it an industry standard for hub seals.

Q: Can you produce customized sizes not listed in the catalog?

Yes, we offer full customization services. Please provide the inner diameter, outer diameter, and height requirements for a tailored production quote.

Q: How do I ensure I am ordering the correct OEM part?

You can match your existing seal against our size catalog or provide the OEM part number (e.g., 12015392B) to ensure a perfect fit.

Q: What is the minimum order quantity (MOQ) for hub seals?

Our standard MOQ is 20 pieces, but we are open to discussing smaller requirements for sample testing or specific project needs.

Q: How does the metal ring in the rubber seal help performance?

The metal ring provides essential structural rigidity, preventing the rubber from distorting under high pressure and ensuring a tight, consistent seal against the shaft.
