U-CUP
Frequently Asked Questions
Q: What is a U-cup and what does the MU200059-460 do?
A: The MU200059-460 is a U-cup hydraulic seal used in pallet jack cylinders and hydraulic systems. It creates a dynamic seal between the piston rod and cylinder bore to prevent hydraulic fluid leakage.
Q: Which pallet jack models use the MU200059-460 U-cup?
A: The MU200059-460 fits manual pallet jacks with the specified bore diameter. Confirm your cylinder bore size and seal pocket depth match this part before ordering.
Q: What materials is the MU200059-460 U-cup made from?
A: This U-cup is typically fabricated from polyurethane or elastomer compounds designed to withstand hydraulic pressures, mineral-based hydraulic oils, and repeated compression cycles in material handling equipment.
Q: What are signs that the MU200059-460 U-cup needs replacement?
A: Replace the U-cup if you observe external hydraulic leaks from the cylinder rod area, slow lowering speed, or jerky piston movement. A failed seal allows fluid loss and reduces lifting capacity.
Q: Can I reuse the MU200059-460 after removal?
A: No. U-cups are single-use seals. Once removed, the elastomer is deformed and cannot create an effective seal. Always install a new MU200059-460 during cylinder service.
