Frequently Asked Questions
Q: What is the LF PR-8535A oil scraper seal designed to do?
A: The LF PR-8535A is a precision nitrile rubber wiper seal engineered for low-pressure oil environments in manual pallet jack hydraulic pump assemblies. It seals a 0.750 inch shaft and prevents oil leakage at the pump housing interface.
Q: What material is the LF PR-8535A made from and what are its hardness specifications?
A: The LF PR-8535A is constructed from high-grade nitrile rubber compound (NBR) with a Shore A hardness specification of 70 ±5. This formulation provides durability and compatibility with ISO 32 and ISO 46 hydraulic oil grades commonly used in pallet jack systems.
Q: Which Lift-Rite pallet jack models does the LF PR-8535A fit?
A: The LF PR-8535A fits Lift-Rite standard manual pallet jack models manufactured since 2004. Alternate model designations include LF PR8535A and LF PR 8535A. Verify your specific model before ordering.
Q: What is the typical lifespan of the LF PR-8535A seal under normal operating conditions?
A: With proper hydraulic oil maintenance and levels, nitrile rubber seals like the LF PR-8535A typically perform for 3000 to 5000 operating hours. Replacement becomes necessary if you observe oil seeping at the pump shaft or reduced pump pressure. Worn seals cannot be repaired and must be replaced.
Q: Does the LF PR-8535A have any published cross-reference or interchange part numbers?
A: No cross-reference part numbers are published for the LF PR-8535A. It is an OEM-specific seal for Lift-Rite equipment. Order using the exact part number LF PR-8535A to ensure correct fitment.
