In industrial and mobile equipment, a failed seal can lead to downtime and cost. DMHUI focuses on durable sealing solutions. Our TCN seal incorporates a reinforced design for sustained performance:

Triple-Metal Skeleton: Provides exceptional radial stability and installation strength, preventing case distortion and ensuring a secure housing fit.

NBR Sealing Lip: Delivers excellent wear resistance and maintains effective sealing across a range of operating temperatures encountered in hydraulic systems.

Spring-Loaded Design: The garter spring applies a consistent radial force to the lip, promoting positive sealing contact and compensating for minor wear over time.

Ideal For Use In:
Hydraulic Components: Various gear pumps, piston pumps, vane pumps, and hydraulic motors.
Construction Equipment: Sealing applications in excavators, loaders, and other machinery hydraulic systems.
Industrial Machinery: Rotary shaft seals in gearboxes, drivetrains, and other industrial equipment requiring fluid retention.

FAQ

Q: Is this seal appropriate for a high-pressure hydraulic pump?
A: Yes. The TCN design with its triple-metal reinforcement is specifically engineered to handle the elevated pressures found in many hydraulic pump and motor applications, offering enhanced stability compared to standard single-case seals.

Q: How do I confirm this is the right size for my machine?
A: Accurately measure your existing seal or housing: the shaft diameter must be 35mm, the housing bore must be 55mm, and the cavity width must accommodate the 12mm seal. Matching the OEM number AP2086F is also a reliable method.

Q: What is your quality assurance?
A: We are a factory-direct source, and our manufacturing processes adhere to ISO9001 standards. This commitment to a certified quality management system ensures the reliability and consistency of every product.

Q: How do I install it without damaging it?
A: Use a flat installation tool or a suitably sized socket. Apply even pressure around the outer metal case—never hammer directly on the rubber lip or the seal's face. Lubricating the rubber lip and the shaft with a little lubricating oil before installation is recommended.

Q: Do you sell other sizes?
A: We carry a wide range of metric and standard oil seal sizes. If you need a different size or type, please use the search function on our website or contact our support team for assistance.
