Engineered to Seal. Built to Perform.
The DMHUI TCN Oil Seal 53x90x10mm is designed for dependable sealing performance in hydraulic and rotating equipment. Built with a durable NBR rubber sealing lip, reinforced metal case, and integrated spring, it helps maintain consistent contact with the shaft for smooth and stable operation.

Suitable for hydraulic pumps, motors, and construction machinery, this seal is a practical solution for maintaining equipment efficiency.

Key Points

Consistent Sealing Performance: The TCN design combines a reinforced structure with a spring-loaded sealing lip, helping maintain stable sealing during continuous shaft rotation.

Durable NBR Construction: The nitrile rubber sealing lip offers excellent resistance to hydraulic fluids, lubricating oils, and greases, maintaining its flexibility and sealing effectiveness across a range of operating temperatures.

Spring-Loaded Seal: A precision garter spring applies uniform radial force to the sealing lip, maintaining constant contact with the rotating shaft and compensating for minor wear over the seal's service life.

Secure Housing Fit: The robust metal outer casing ensures a snug, stable fit within the housing bore, reducing the risk of seal displacement or leakage due to vibration or pressure spikes.

Direct Replacement: Manufactured to exact metric specifications (53x90x10mm) for a hassle-free fit in compatible hydraulic pumps, motors, and rotating shaft applications.

FAQ

Q: Is this seal suitable for both hydraulic pumps and motors?
A: Yes. This 53x90x10mm TCN seal is commonly used in both hydraulic pumps and motors where a reliable high-pressure rotary shaft seal is required. Always verify that your shaft and housing dimensions match the specifications.

Q: What fluids is this seal compatible with?
A: The NBR rubber material is compatible with most mineral-based hydraulic oils, lubricating oils, and greases. For use with other fluids such as fuels, synthetic oils, or chemicals, please verify compatibility prior to installation.

Q: How do I know if this is the correct size for my application?
A: Measure your shaft diameter (must be 53mm), housing bore diameter (must be 90mm), and the seal cavity width (must accommodate 10mm). These three dimensions must match for proper fit and sealing function.

Q: What is the proper installation method?
A: Clean the shaft and housing thoroughly. Apply a thin film of clean oil to the seal lip and shaft. Press the seal squarely into the housing using a flat installation tool or appropriately sized socket, applying even pressure to the outer metal case only. Avoid striking the rubber lip directly.

Q: Do you offer other sizes for hydraulic applications?
A: Yes. We stock a wide range of metric oil seals in various sizes and types, including TCV, TCZ, and other configurations. Please use our search function or contact us with your specific requirements.

Note: This product is designed as a replacement component. Verify all dimensions and application suitability prior to purchase. Proper installation is essential for optimal performance and service life.
