Frequently Asked Questions
Q: What is the primary purpose of oil seal 800087811?
A: Oil seal 800087811 prevents hydraulic fluid or gear oil leakage from rotating shafts in electric lift truck drivetrains, transmissions, or hydraulic pump assemblies. Sealing failure causes fluid loss, equipment malfunction, and contamination of the work environment.
Q: Which electric lift truck models and components use oil seal 800087811?
A: Oil seal 800087811 fits specific shaft locations in electric lift trucks from manufacturers like Crown, Toyota, Raymond, Jungheinrich, and Linde. Common applications include transmission output shafts, hydraulic pump drives, and motor coupling assemblies. Verify shaft diameter and seal cavity dimensions match your equipment.
Q: What material composition does seal 800087811 have?
A: Oil seal 800087811 typically features a nitrile rubber (NBR) lip construction for general hydraulic oil and gear lubricant compatibility. The metal grommet provides shaft fit and housing retention. This material combination offers good sealing performance across standard industrial temperature ranges.
Q: How long does oil seal 800087811 typically remain serviceable?
A: Oil seal 800087811 service life is typically 2000 to 5000 operating hours under normal conditions. High-temperature operation, contaminated fluid, or misalignment reduces seal life significantly. Monitor for fluid seepage around the seal area as an early warning of failure.
Q: What are the size specifications for seal 800087811?
A: Oil seal 800087811 specific dimensions, shaft diameter, and bore size depend on your equipment component location. Contact us with your lift truck model, serial number, and component assembly to confirm exact seal dimensions required.
Q: Does oil seal 800087811 have cross-reference or OEM equivalent part numbers?
A: Cross-reference part numbers for seal 800087811 exist through various OEM suppliers depending on your equipment manufacturer. Provide your lift truck model and component assembly details for accurate cross-reference identification.
