Frequently Asked Questions
Q: What is the RA 1055355-01 hydraulic cylinder seal kit used for?
A: The RA 1055355-01 is a hydraulic cylinder seal kit engineered to maintain lift and freelift cylinder pressure integrity. It prevents hydraulic fluid leakage and preserves internal pressure in high-pressure hydraulic systems on Raymond forklifts.
Q: Which Raymond forklift models does the RA 1055355-01 seal kit fit?
A: The RA 1055355-01 is compatible with Raymond 7400, 7420, and 7440 series forklifts. It serves as a direct OEM replacement seal kit for both lift and freelift hydraulic cylinders on these models.
Q: What materials are used in the RA 1055355-01 seal kit?
A: The RA 1055355-01 uses nitrile rubber and PTFE composite seals. These materials are selected for durability and leak prevention in high-pressure hydraulic applications, meeting strict OEM material standards.
Q: What symptoms indicate the RA 1055355-01 seals need replacement?
A: Signs of seal failure include visible hydraulic fluid leakage around cylinder rods, loss of lift height or power, slow or jerky lift operation, and declining pressure readings on hydraulic gauges. Any leakage requires immediate attention to prevent system damage.
Q: How long does the RA 1055355-01 seal kit typically last?
A: Seal lifespan depends on usage intensity, hydraulic fluid condition, and operating temperature. Regular maintenance and clean hydraulic fluid extend service life. Inspect seals annually and replace when leakage appears or after approximately 2000 to 3000 hours of operation in heavy-duty environments.
