Frequently Asked Questions
Q: What does the KI CB-SK seal kit contain?
A: The KI CB-SK is a direct replacement hydraulic seal kit for King CB Series manual pallet jack hydraulic cylinders. It contains high-pressure nitrile (NBR) seals with PTFE backing designed for piston and rod applications in 1.00 inch bore and 0.625 inch rod systems.
Q: What is the maximum hydraulic pressure rating?
A: The seal kit is rated for up to 3000 PSI maximum hydraulic working pressure. This is the standard pressure rating for manual pallet jack hydraulic systems. Do not exceed this pressure rating as it will compromise seal integrity and safety.
Q: What materials are used in the seals and why does it matter?
A: The seals are made from Nitrile (NBR) with PTFE backup material and meet ASTM D2000 requirements. NBR provides excellent resistance to mineral-based hydraulic oils and maintains flexibility across typical warehouse temperature ranges. PTFE backing prevents extrusion and extends seal life under high pressure.
Q: What flow rate can these seals support?
A: The seals support flow rates up to 2.5 GPM at rated pressure. This is consistent with the hydraulic pump output of King CB Series manual pallet jacks.
Q: Is this kit compatible with electric pallet jacks?
A: The KI CB-SK is designed specifically for King CB Series equipment, which are manual hydraulic pallet jacks. Before ordering, confirm your pallet jack has a 1.00 inch bore and 0.625 inch rod. Check the original equipment documentation to verify compatibility with your specific model.
Q: How long do hydraulic seals typically last before replacement?
A: Seal lifespan depends on usage frequency, oil condition, and operating temperature. Clean hydraulic oil and regular maintenance extend seal life. Most hydraulic seals in warehouse equipment need replacement every 2 to 5 years or when oil leaks or reduced lifting pressure occurs.
