Frequently Asked Questions
Q: What is the RA 11039-22 oil seal and what does it prevent?
A: The RA 11039-22 is a genuine OEM hydraulic oil seal for Raymond electric lift trucks and electric pallet jacks. It prevents hydraulic fluid leakage at rotating shaft interfaces within pump assemblies, valve bodies, and hydraulic cylinders, maintaining system pressure and preventing fluid loss.
Q: What are the material specifications of the RA 11039-22 seal?
A: The RA 11039-22 features a nitrile rubber (NBR) sealing lip bonded to a steel case with a stainless steel garter spring. This construction provides reliable sealing against mineral hydraulic oils, resists temperature variations, and maintains lip tension under pressure cycling in industrial hydraulic systems.
Q: Which Raymond electric pallet jacks and lift trucks use the RA 11039-22 seal?
A: The RA 11039-22 seal is compatible with specific Raymond electric pallet jack and electric lift truck hydraulic assemblies. Verify your equipment model and hydraulic system configuration to confirm the correct seal before ordering.
Q: How long does the RA 11039-22 oil seal typically last?
A: Under normal operating conditions, hydraulic seals perform reliably for several years of continuous duty. Lifespan depends on hydraulic fluid type, operating temperature, pressure cycling frequency, equipment maintenance, and contamination levels in the hydraulic system.
Q: What symptoms indicate the RA 11039-22 seal has failed?
A: Signs of seal failure include visible hydraulic fluid dripping or pooling, reduced lift or drive performance, soft or spongy controls, hose pressure loss, or dark discoloration on the seal housing exterior. Failed seals allow hydraulic fluid loss and air entry, compromising system function and equipment safety.
