Frequently Asked Questions

Q: What is the main difference between a COMBI seal and a KASSETTE seal?

COMBI seals are typically combined lip seals, while KASSETTE seals are integrated units that include the seal and the housing/sleeve, offering easier installation and better stability in the hub.

Q: Can you manufacture rubber seals with non-standard dimensions?

Yes, we offer fully customized seal manufacturing. Please provide your required dimensions (Inner Diameter x Outer Diameter x Thickness) or a technical drawing for a quote.

Q: Which materials are best for high-temperature tractor applications?

For high-temperature or chemically aggressive environments, we recommend HNBR or NBR+PTFE materials, which offer superior thermal stability compared to standard rubber.

Q: How do I ensure the oil seal I order matches my OEM part number?

Our catalog cross-references OEM part numbers (such as 12019113B) with precise dimensions. Simply provide the part number, and we will verify the size for you.

Q: Why is a metal ring included in the rubber seal design?

The metal ring provides structural reinforcement, ensuring the seal maintains its shape under high pressure and preventing the rubber from migrating or leaking.

Q: What is the minimum order quantity for bulk hub oil seals?

Our minimum order quantity (MOQ) is 20 pieces, which allows us to maintain strict quality control and competitive pricing for our clients.
