Frequently Asked Questions
Q: What is the purpose of the 380050-002 oil seal?
A: Oil seals prevent lubricant leakage from bearing cavities and keep external contaminants out of internal components. This seal is typically a rubber or synthetic elastomer lip that rides against a shaft surface. Loss of seal integrity causes oil loss, bearing damage, and component failure.
Q: Which forklift equipment uses this oil seal?
A: The 380050-002 seal is compatible with bearing assemblies on Crown, Toyota, Raymond, Yale, Hyster, and Jungheinrich equipment. Common applications include wheel hubs, mast rollers, load wheels, and pump bearings. Confirm your equipment type and bearing cavity dimensions before ordering.
Q: What material is this oil seal made from?
A: Oil seals are typically made from nitrile rubber (NBR), viton, or polyurethane compounds. Material selection depends on fluid type (mineral oil, biodegradable fluid, or grease) and temperature range. Nitrile is standard for mineral oil applications. Verify material compatibility with your equipment lubricant type.
Q: What causes oil seal failure?
A: Seals fail due to material degradation from age, heat exposure, chemical incompatibility, shaft wear that breaks contact, contamination, or improper installation. Signs of failure include visible oil weeping at the seal location, loss of bearing lubrication, and bearing noise or overheating. Replace seals when leakage is detected to prevent bearing damage.
