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 is compatible with Mobile ML55 (newer) and ML55L manual pallet jacks. It fits axle configurations and supersedes bearing variants used on older models.
Q: What are the key specifications of the MO 101/210-1-A-ST wheel assembly?
A: This assembly features a polyurethane tread bonded to a reinforced nylon hub. It includes dual sealed ball bearings for smooth steering operation and extended service life in manual pallet jack applications.
Q: What cross-reference part numbers are equivalent to the 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. For heavy-duty applications, use the MO 101/210-1-A-HD ultra-poly variant.
Q: Why upgrade from the older MO 100/210-A to the MO 101/210-1-A-ST?
A: The MO 101/210-1-A-ST provides better load distribution, improved bearing life, and full compatibility with newer Mobile pallet jack designs compared to older models. The dual sealed ball bearings also reduce maintenance needs compared to earlier bearing designs.
Q: What material composition makes up the MO 101/210-1-A-ST hub?
A: The assembly uses a reinforced nylon hub with polyurethane tread. This combination provides good load capacity while remaining lightweight, making it ideal for manual pallet jack steering applications that require both durability and ease of operation.
Q: How should the MO 101/210-1-A-ST wheel be stored and maintained?
A: Store the wheel assembly in a dry environment away from direct sunlight and extreme temperatures. Periodically check bearing seals for any signs of contamination or wear. Clean with mild soap and water; avoid harsh chemicals. Inspect the polyurethane tread for cracks or damage before use.
Q: What is the expected service life and reusability of the MO 101/210-1-A-ST?
A: The sealed ball bearings and polyurethane tread are designed for extended service life in typical manual pallet jack operations. With proper maintenance and storage, the wheel assembly can be reused across multiple pallet jack applications, subject to inspection for bearing condition and tread wear before reinstallation.
