Frequently Asked Questions
Q: What is the YL 550069217-A load wheel?
A: The YL 550069217-A is a pre-assembled polyurethane load wheel assembly with sealed bearings, designed as a direct replacement for Yale MP and MPB series electric pallet jacks. The polyurethane tread (97A durometer) is molded onto a machined cast iron core for durability and load support.
Q: Which Yale equipment models does this wheel fit?
A: This load wheel is engineered for Yale MP and MPB series electric pallet jacks. Always verify that the bearing and wheel mounting diameter match your specific equipment before ordering.
Q: What does 97A durometer hardness mean?
A: Durometer 97A indicates a durable, load-bearing polyurethane compound ideal for material handling applications. The ±2A tolerance ensures consistency across production batches. Higher durometer ratings provide greater wear resistance and extended service life under heavy-use conditions.
Q: Are the bearings pre-installed?
A: Yes. The YL 550069217-A comes factory-equipped with sealed 6203-2RS ball bearings pre-installed in the wheel hub. The 2RS designation means double-sided rubber seals that protect against dust and contamination. The bore accommodates standard Yale axle pins.
Q: What material is the wheel core and why cast iron?
A: The core is cast iron, machined to precise specification with a natural (uncoated) finish. Cast iron provides the structural strength required to support heavy loads while the machined surface ensures true rolling geometry and proper axle fitment for reliable performance.
Q: How should this wheel be stored?
A: Store the load wheel in a clean, dry location away from extreme temperatures and moisture. Keep the bearings dry and protect the wheel from mechanical damage. Store indoors at temperatures between 32°F and 86°F for optimal bearing seal performance.
