Frequently Asked Questions
Q: What is the load capacity rating for the MU 90304-A load wheel assembly?
A: The MU 90304-A is designed for pallet trucks with load capacities up to 5000 lbs at a 24-inch load center. Load rating depends on your complete truck configuration, so verify compatibility with your specific equipment.
Q: What bearing type does the MU 90304-A use and why are they sealed?
A: The MU 90304-A uses 6204-2RS sealed bearings with a 20 mm bore. The 2RS designation means the bearing is sealed on both sides, protecting against contaminants and extending bearing life in warehouse and material handling applications.
Q: What does the polyurethane Shore hardness 70D mean for the MU 90304-A tread?
A: Shore hardness 70D indicates medium-hardness polyurethane that balances durability and load-bearing capacity. This rating provides good wear resistance while maintaining adequate grip on most floor surfaces. Harder compounds resist abrasion; softer compounds provide better traction.
Q: How does the MU 90304-A compare to part numbers it supersedes like the 759?
A: The MU 90304-A is a direct replacement for Multiton 759 and equivalent to models 90304, 325P, and A212. The MU 90304-A includes sealed 6204-2RS bearings and is engineered for M and S frame electric pallet trucks up to 5000 lbs capacity.
