Frequently Asked Questions
Q: Which Bishamon pallet jacks use the BI 80800128 O-Ring?
A: The BI 80800128 is specified for Bishamon BS-55 manual pallet jack hydraulic units, including machines with serial numbers from 203001 to 305004. Verify your unit serial number falls within this range before ordering.
Q: What is the material composition of the BI 80800128?
A: The BI 80800128 is manufactured from nitrile rubber, a synthetic elastomer selected for high-pressure hydraulic sealing. Nitrile provides excellent fluid resistance and durability in pallet jack pump and cylinder applications.
Q: Where is the BI 80800128 O-Ring located in the pallet jack?
A: This O-Ring is installed at the ram base on BS-55 hydraulic units. It seals the connection between the cylinder and pump, preventing fluid loss during lifting and lowering cycles.
Q: What pressure rating does the BI 80800128 O-Ring handle?
A: The BI 80800128 is rated for high-pressure fluid sealing in pallet jack applications, typically 3000 PSI or higher. This rating is appropriate for the load and pressure demands of BS-55 manual hydraulic systems.
Q: How do I verify the BI 80800128 is the correct replacement for my pallet jack?
A: Confirm your equipment is a Bishamon BS-55 model and verify the serial number range (203001 to 305004). Nitrile O-Ring construction and ram-base position are standard for this equipment specification.
