Frequently Asked Questions
Q: What pallet jack models use the MO 101/210-A-ST steer wheel?
A: The MO 101/210-A-ST fits Mobile manual pallet jack model ML55 and comparable manual pallet jacks using nylon hub steering wheel assemblies. Confirm your equipment model and hub material match this specification before ordering, as the nylon design is not interchangeable with aluminum hub variants.
Q: What is the hub material for the MO 101/210-A-ST?
A: The MO 101/210-A-ST features a reinforced nylon hub with polyurethane tread and 0.75 inch inner diameter ball bearings. Nylon hubs are lighter than aluminum and offer good performance in standard manual pallet jack steering applications. This material is not directly interchangeable with the aluminum hub variant (MO 101/210-A-HD).
Q: What bearing size does the MO 101/210-A-ST use?
A: The MO 101/210-A-ST is equipped with 0.75 inch (3/4 inch) inner diameter ball bearings. Verify your pallet jack axle matches this diameter specification. Using bearings with incorrect inner diameter will cause wobbling, premature wear, and unsafe steering performance.
Q: Are there alternative part numbers for the MO 101/210-A-ST?
A: Yes, cross-reference part numbers for the MO 101/210-A-ST include 101/210-A-ST, 101/210-1-A-ST, and MO 101/210-1-A-ST. The MO 101/210-A-HD (aluminum hub variant) is referenced in the assembly family but is not directly interchangeable. Use the ST designation when ordering to ensure you receive the nylon hub version.
Q: How does the MO 101/210-A-ST compare to the aluminum hub version?
A: The MO 101/210-A-ST uses a reinforced nylon hub and polyurethane tread, while the MO 101/210-A-HD features an aluminum alloy hub with ultra-polyurethane tread. Both use 0.75 inch bearings, but the designs are not directly interchangeable. Choose based on your original equipment specification. Nylon hubs are lighter; aluminum hubs offer greater durability in heavy-use environments.
