High-performance rubber sealing technology engineered for extreme attrition resistance and maximum leak prevention in heavy-duty wheel hubs.
Our combi oil seal combines advanced elastomer chemistry with precision metal reinforcements to ensure zero-leakage in the most demanding agricultural and industrial environments. We focus on durability, thermal stability, and effortless installation.
Utilizing high-grade NBR and HNBR, our seals maintain elasticity under extreme temperature fluctuations, preventing brittle failure.
Tolerances are kept to microns to ensure a perfect fit, reducing friction and extending the lifespan of the wheel hub assembly.
Specially formulated compounds resist wear and tear from dust, mud, and metallic debris, ensuring continuous protection.
Eliminate lubricant loss and prevent contaminants from entering the gear system with our high-pressure seal architecture.
From OEM standards to bespoke dimensions, we deliver custom-molded rubber components with industry-leading lead times.
Reduce maintenance downtime and replacement costs through superior material wear resistance and stable sealing.

Yes, we offer full customization. Provide us with your inner diameter, outer diameter, and thickness, and we can produce a bespoke seal for your machinery.
We recommend HNBR or PTFE-enhanced rubber for high-temperature applications as they offer superior thermal stability compared to standard NBR.
Ensure the shaft is clean and free of burrs. Use a dedicated seal driver tool to apply even pressure across the seal face to avoid deformation.
Our standard sample lead time is 7 days, ensuring you can verify fit and performance before placing a bulk order.
The metal ring provides structural rigidity, preventing the seal from distorting under high pressure and facilitating precise seating in the housing.
