Frequently Asked Questions
Q: What is the YL 550091350 bushing and its function?
A: The YL 550091350 bushing is a wear-resistant bearing component used in Yale manual pallet jack assemblies. It provides a low-friction interface between moving shafts and pump linkage, reducing friction and wear while maintaining precise alignment during lifting and lowering.
Q: What material is the YL 550091350 bushing made from?
A: The YL 550091350 is typically constructed from bronze, nylon, or composite bearing material depending on the application. These materials provide low-friction operation, resist corrosion, and reduce wear on mating shafts compared to direct metal-to-metal contact.
Q: How often does the YL 550091350 bushing need to be replaced?
A: Bushing life depends on use frequency and lubrication maintenance. Under normal warehouse conditions with regular lubrication, bushings typically last 3-5 years. Heavy-use equipment or inadequate lubrication will require more frequent replacement.
Q: What are signs that the YL 550091350 bushing is worn?
A: Worn bushings cause jerky or stiff pump action, increased friction resistance when lifting or lowering, lateral shaft movement or play, clicking or grinding sounds during operation, or visible wear grooves on the bushing surface. Any of these indicates replacement is needed.
Q: Is lubrication required for the YL 550091350 bushing?
A: Yes. Regular lubrication at connection points extends bushing life and maintains smooth pump operation. Consult your equipment manual for recommended lubrication intervals and approved lubricant types. Inadequate lubrication accelerates bushing wear and increases maintenance costs.
