Frequently Asked Questions
Q: What does the BI 52013563 U-Cup seal do in a Bishamon hydraulic unit?
A: The BI 52013563 is a U-Cup hydraulic seal that prevents internal leakage in the Bishamon BS-55 pallet jack hydraulic pump and cylinder assemblies. It creates a dynamic seal between moving hydraulic components to maintain system pressure and lifting performance.
Q: Which pallet jacks use the BI 52013563 U-Cup seal?
A: The BI 52013563 is compatible with the Bishamon BS-55 manual pallet jack hydraulic unit. Alternate model designations are BS55 and BS 55. This seal is a standard OEM component for hydraulic assemblies in this series.
Q: What are the cross-reference part numbers for the BI 52013563?
A: The BI 52013563 U-Cup seal is also referenced as BS52013563 and manufacturer number 52013563. These are equivalent part designations for the same OEM component.
Q: What symptoms indicate the BI 52013563 seal needs replacement?
A: Signs of U-Cup seal failure include hydraulic fluid leaking from the pump or cylinder, loss of lift pressure, difficulty maintaining raised load height, or slow descent when the pallet jack is loaded. These indicate internal seal degradation on BS-55 units.
Q: How long does a BI 52013563 U-Cup seal typically last in a BS-55 pallet jack?
A: Hydraulic seals like the BI 52013563 typically last 3 to 5 years under normal industrial use, depending on operating hours, fluid maintenance, and environmental conditions. Seals in high-temperature or wet storage environments may degrade faster and require replacement sooner.
Q: Is the BI 52013563 an OEM part or aftermarket?
A: The BI 52013563 is an OEM Bishamon part. The OEM part number is BI 52013563 and the manufacturer part number is also BI 52013563. This is an original specification component for BS-55 hydraulic assemblies.
