Frequently Asked Questions
Q: What are the specifications for the YL 550069217-A load wheel?
A: The YL 550069217-A is a pre-assembled poly load wheel featuring a polyurethane tread with 97A durometer hardness (±2A tolerance) molded onto a cast iron core. The wheel comes pre-installed with sealed 6203-2RS ball bearings with a 17 mm bore. The core is machined cast iron with a natural finish.
Q: Which Yale electric pallet jack models is this load wheel compatible with?
A: The YL 550069217-A is designed as a direct replacement load wheel for Yale MP and MPB series electric pallet jacks. Verify the bearing bore size and wheel mounting diameter match your equipment before ordering.
Q: What is the durometer rating and why does it matter?
A: The tread has a 97A durometer hardness rating, which indicates a durable, load-bearing polyurethane compound suitable for general material handling applications. The ±2A tolerance ensures consistency across batches. Higher durometer means greater wear resistance and longer service life under heavy use.
Q: Are the bearings pre-assembled and sealed?
A: Yes. The YL 550069217-A comes with sealed 6203-2RS bearings pre-installed in the wheel hub. The 2RS designation indicates double-sided rubber seals that protect against contamination. A 17 mm bore accommodates standard axle pins for Yale equipment.
Q: What is the core material and finish?
A: The load wheel core is cast iron, machined to specification, with a natural (uncoated) finish. Cast iron provides the strength needed to support heavy loads while the machined surface ensures true rolling and proper axle fitment.
