Frequently Asked Questions
Q: What are the dimensions and material specifications of the PU AA-7.25X2 PMWB-ST?
A: The PU AA-7.25X2 PMWB-ST is a 7.25 inch diameter steer wheel with a 2.00 inch tread width. It features a polyurethane tread bonded to a nylon hub, with dual precision 20mm ID ball bearings for smooth rotation and extended bearing life in typical material handling applications.
Q: Is the PU AA-7.25X2 PMWB-ST compatible with AA5000 and AA5500 pallet jacks?
A: Yes. The PU AA-7.25X2 PMWB-ST is a direct replacement for both Pallet Mule AA5000 and AA5500 models. It supersedes older AA-7.25x2 configurations and is equivalent to the AA-7.25x2 PMWB and AA-7.25x2 PMWB-HD variants in terms of frame compatibility.
Q: What is the difference between the PMWB-ST and PMWB-HD variants?
A: The PMWB-ST features a nylon hub while the PMWB-HD uses an aluminum hub. The nylon variant (PMWB-ST) is typically lighter and suitable for standard warehouse environments, whereas the aluminum hub design (PMWB-HD) offers greater durability in demanding applications or outdoor use.
Q: What bearing specifications ensure reliability in the PMWB-ST assembly?
A: This assembly includes dual precision 20mm ID ball bearings that are sealed to prevent contamination from dust and moisture. These bearings are designed for smooth steer wheel operation across typical warehouse floor surfaces and provide consistent performance under standard pallet jack loading conditions.
Q: Can I interchange the PMWB-ST with the full nylon AA-7.25x2 variant?
A: Yes. All three variants, the PMWB-ST, PMWB-HD, and the basic AA-7.25x2, are direct fit replacements for each other on AA5000 and AA5500 frame assemblies. Choose based on your hub material preference and operating environment requirements.
