Frequently Asked Questions
Q: What is the BI 52003563 U Packing Kit?
A: The BI 52003563 is an OEM hydraulic seal kit engineered for Bishamon BS-55 manual pallet jack cylinders. It is a U-ring packing designed for the hydraulic ram piston and provides reliable sealing performance in industrial material handling applications.
Q: What material and hardness specifications does the BI 52003563 have?
A: The BI 52003563 is manufactured from 70 Shore A nitrile rubber (NBR) compound, which provides optimal balance between flexibility and durability for hydraulic piston sealing at pressures up to 3000 PSI.
Q: What equipment does the BI 52003563 seal kit fit?
A: The BI 52003563 is an exact-fit OEM component for Bishamon BS-55 manual pallet jack cylinders and is compatible with the entire BS-55 series family of pallet jacks.
Q: What is the design cycle life for the BI 52003563 seal kit?
A: The BI 52003563 is designed for a minimum of 50,000 hydraulic cycles, engineered to deliver high cycle durability and continuous service in demanding industrial material handling environments.
Q: When should I replace the BI 52003563 U packing kit?
A: Replace the seal kit if the pallet jack cylinder leaks hydraulic fluid, loses pressure, or exhibits sluggish or uneven lifting and lowering. Nitrile seals degrade over time with heat, pressure cycles, and hydraulic fluid exposure. A compromised seal kit will allow internal leakage and loss of lifting force.
