Frequently Asked Questions
Q: What does the 550023492-A assembly include?
A: The 550023492-A is a complete load wheel assembly featuring a 3.25 inch diameter by 4.50 inch width polyurethane tread on a cast iron hub. The assembly includes 6203-2RS sealed ball bearings (17mm inner diameter), mounting hardware, and lubrication fittings. This is a ready-to-use subassembly, not just a wheel.
Q: Is the 550023492-A compatible with Yale MPB040 and MPB045VG models?
A: Yes, the 550023492-A is compatible with Yale MPB040 and MPB045VG electric pallet jack models. It also replaces multiple Yale part numbers including 650546, 0652696-00, 0652696-01, 0655092-00, and 2302392. Cross-reference part numbers include 524148750-A and 5241487-50.
Q: What is the durometer rating of the polyurethane tread?
A: The 550023492-A uses a 95A durometer polyurethane material, which provides a balance of hardness and resilience for industrial material handling. This durometer rating delivers adequate load support while maintaining grip on standard warehouse surfaces.
Q: Are the bearings sealed and maintenance-free?
A: Yes. The assembly features 6203-2RS sealed ball bearings with contact seals that protect against dirt and debris ingress. These sealed bearings require minimal maintenance. Periodic lubrication through the fitting extends bearing life in high-use environments.
Q: What is the weight capacity of this load wheel?
A: The 550023492-A load wheel assembly is designed to support the full load capacity of Yale MPB040 (4,000 lbs) and MPB045VG (4,500 lbs) electric pallet jacks. The cast iron hub and sealed bearings ensure reliable performance under continuous industrial use.
Q: Is this wheel suitable for outdoor or wet environments?
A: The 550023492-A is designed primarily for indoor warehouse and distribution environments. The sealed bearings provide protection against moisture and dirt, but extended exposure to wet conditions or corrosive environments may reduce bearing life. Store in a dry location when not in use.
