Frequently Asked Questions
Q: What equipment models does the MO 101/210-1-A-ST steer wheel fit?
A: The MO 101/210-1-A-ST fits Mobile ML55 (newer) and ML55L manual pallet jacks. It is compatible with 20mm axle configurations. This assembly supersedes 3/4-inch bearing variants used on older models.
Q: What are the specifications of the MO 101/210-1-A-ST wheel assembly?
A: The MO 101/210-1-A-ST features a 7-inch diameter polyurethane tread bonded to a reinforced nylon hub. It has a 20mm bearing bore with dual sealed ball bearings for smooth operation and extended service life in manual pallet jack steering systems.
Q: What cross-reference part numbers are equivalent to MO 101/210-1-A-ST?
A: The MO 101/210-1-A-ST replaces MO 101/210-A-ST, supersedes MO 101/210-1-A, and is equivalent to MO 101/210-1-HD. It also supersedes the older MO 100/210-A (3/4 inch bearing variant). For heavy-duty applications, the MO 101/210-1-A-HD is the ultra-poly equivalent.
Q: Why upgrade from MO 100/210-A to MO 101/210-1-A-ST?
A: The MO 101/210-1-A-ST uses a 20mm bearing bore versus the 3/4-inch variant in older models. This change provides better load distribution, improved bearing life, and compatibility with newer Mobile pallet jack designs. The dual sealed ball bearings reduce maintenance intervals compared to earlier bearing designs.
Q: What material is the hub on the MO 101/210-1-A-ST?
A: The MO 101/210-1-A-ST uses a reinforced nylon hub with polyurethane tread. This construction provides good load capacity while remaining lightweight, making it ideal for manual pallet jack steering systems that require both durability and ease of operation.
