Frequently Asked Questions
Q: What is the SE-291 oil seal and what is its purpose on electric lift trucks?
A: The SE-291 is a rotary shaft seal designed for hydraulic pump applications on electric lift trucks. This oil seal prevents hydraulic fluid leakage from the pump shaft and protects internal hydraulic components from contamination. The SE-291 maintains system pressure integrity and fluid retention during pallet truck operation.
Q: What are the material specifications of the SE-291 seal?
A: The SE-291 features a nitrile rubber (NBR) primary sealing element with a steel case containing anti-corrosion treatment. Nitrile rubber provides compatibility with standard mineral hydraulic fluids and synthetic blends. The steel case provides structural support and is designed for press-fit installation within hydraulic pump bodies.
Q: What is the expected service life of the SE-291 seal?
A: The SE-291 is engineered for a minimum operational life of 1000 hours at rated hydraulic pressure. Actual service life depends on hydraulic fluid condition, contamination levels, operating temperature range, and pump duty cycle. Regular fluid maintenance and contamination control extend seal life significantly.
Q: Which electric lift truck brands use the SE-291 seal?
A: The SE-291 is compatible with hydraulic pumps across electric pallet truck models from Crown, Toyota, Raymond, Yale, Jungheinrich, Linde, and other major manufacturers. Cross-reference your truck model and hydraulic pump specification to confirm compatibility. No equivalent cross-reference part numbers are available from OEM sources.
