Frequently Asked Questions
Q: What Pallet Mule models is the PU AA-7.25X2 PM-ST compatible with?
A: This steering wheel assembly is engineered for Pallet Mule AA5000 and AA5500 series manual pallet jack frames. The design integrates with the traverse steering mechanism used on these models and supersedes earlier steer wheel designs.
Q: What are the wheel dimensions?
A: These dimensions are designed specifically for AA5000 and AA5500 frame geometry. Verify your existing wheel dimensions before ordering to confirm compatibility.
Q: What materials are used in this steering wheel assembly?
A: The assembly combines a polyurethane (PU) tread with a nylon-reinforced polypropylene hub core. This combination provides durability for repeated directional control in material handling operations while resisting wear and environmental exposure.
Q: How is the bearing system designed?
A: The wheel includes an integrated sealed bearing system built into the nylon-reinforced hub. The sealed design protects against debris and moisture contamination, supporting reliable steering performance across repeated pallet jack operations.
Q: What are the alternative part number designations?
A: The product is identified as part number PU AA-7.25X2 PM-ST. Alternative designations include AA-7.25x2 PMWB-ST, AA7.25X2 PMST, and the base part number AA-7.25X2. These refer to the same steering wheel assembly.
Q: What hardware components are required for mounting?
A: The assembly mounts using the AA-46 steer wheel axle, AA-29 shoulder bolt, and AA-29N lock nut. These components work together to secure the wheel assembly to the AA5000 or AA5500 frame.
Q: How does this wheel improve upon earlier designs?
A: This assembly features an improved polymer composite hub design compared to older steer wheel series (AA-8x2). The upgraded hub provides enhanced structural stability and extended service life in manual pallet jack applications.
