Frequently Asked Questions
Q: What is the wheel diameter and material composition of the AA-7.25X2 PMWB-HD?
A: The AA-7.25X2 PMWB-HD is a steer wheel assembly with ultra-polyurethane tread bonded to an aluminum hub. This configuration represents an upgrade from older designs, offering improved maneuverability while maintaining load capacity.
Q: Which pallet jack models does the AA-7.25X2 PMWB-HD fit?
A: This steer wheel assembly is compatible with Pallet Mule AA5000 and AA5500 frame assemblies. It is a direct replacement for equipment originally equipped with the older AA-8x2 PMWB-HD configuration.
Q: What bearing specifications are included in this assembly?
A: The AA-7.25X2 PMWB-HD includes an integrated precision bearing assembly with shoulder bolt retention hardware for secure axle mounting. The bearing design provides smooth steer wheel rotation and extended service life under normal pallet jack operating conditions.
Q: What alternative part numbers or variants are available for this steer wheel?
A: The AA-7.25X2 PMWB-HD has two primary alternatives: the AA-7.25X2 PMWB-ST which features a nylon hub instead of aluminum, and the AA-7.25X2 which is a full nylon variant. All three fit the same equipment frame assemblies but offer different hub material options for specific operating environments.
Q: How does the 7.25 inch wheel diameter compare to older configurations?
A: The wheel replaces the superseded configuration (AA-8x2 PMWB-HD). The smaller reduces the overall ride height and improves maneuverability on material handling equipment while the ultra-polyurethane tread maintains durability and provides superior grip on warehouse floors.
Q: How should this wheel assembly be stored when not in use?
A: Store the wheel assembly in a dry, climate-controlled environment away from direct sunlight and extreme temperatures. Keep the bearing assembly clean and protected from dust and moisture. If stored long-term, periodically rotate the wheel to prevent flat-spotting and ensure the bearing maintains even load distribution.
