Frequently Asked Questions

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

COMBI seals are typically integrated units for standard sealing, while KASSETTE seals feature a reinforced outer casing that provides better structural support and stability in heavy-duty axle applications.

Q: Are these seals compatible with DANA axle systems?

Yes, our seals are specifically designed to replace OEM parts for DANA systems, including part numbers 3429790M1 and 3429790M2, ensuring perfect dimensions and performance.

Q: Can you manufacture customized sizes if my measurements aren't in the catalog?

Absolutely. We offer full customization services for the rubber and plastic products industry. Simply provide us with your required inner diameter, outer diameter, and thickness.

Q: What material is used to ensure attrition resistance?

We use high-grade industrial rubber (including NBR and options for PTFE) reinforced with a metal ring to withstand friction and high-pressure environments.

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

Our standard MOQ is 20 pieces per size, making it accessible for both small repair shops and large-scale industrial distributors.

Q: How do these seals improve the efficiency of a tractor's wheel hub?

By preventing lubricant leakage and blocking external debris, these seals reduce friction and heat buildup, which prevents premature bearing failure and reduces overall maintenance costs.
