TC 91306-62500

Frequently Asked Questions

Q: What are the material specifications for the TC 91306-62500 seal?
A: The TC 91306-62500 is manufactured from nitrile rubber (NBR) compound and meets RMA Class A tolerances. Nitrile rubber provides excellent fluid retention and resistance to hydraulic oils and coolants, making it suitable for electric lift truck hydraulic systems. The RMA Class A specification ensures consistent performance and durability across thermal cycling and pressure variations typical in forklift hydraulic assemblies.

Q: Which electric lift truck models use the TC 91306-62500 hydraulic shaft seal?
A: The TC 91306-62500 is an OEM part designed for electric lift truck assemblies from major manufacturers including Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, Linde, Clark, Mitsubishi, CAT, and BT. Verify the part number and seal cavity dimensions against your equipment documentation before ordering to ensure correct fitment.

Q: What is the primary function of this O ring seal in hydraulic systems?
A: The TC 91306-62500 serves as a hydraulic shaft seal providing two critical functions: fluid retention (preventing hydraulic fluid leakage from cylinders and motors) and contamination exclusion (blocking dirt, water, and particulates from entering sealed cavities). This dual function is essential for maintaining system pressure and component longevity in electric pallet truck lift mechanisms.

Q: How does nitrile rubber compound affect seal lifespan in cold storage and wet environments?
A: Nitrile rubber maintains elasticity across a wide temperature range, making it suitable for both ambient and cold storage warehouse operations. However, extended exposure to water or high-moisture environments can accelerate degradation. Monitor seals regularly in wet conditions and replace if you notice swelling, hardening, or fluid weeping around the seal interface. Standard maintenance cycles typically range 12-24 months depending on operating conditions.
