Frequently Asked Questions
Q: What are the material and dimensional specifications for the MO 120E8S-A steel steer wheel assembly?
A: The MO 120E8S-A features a 7-inch diameter solid steel tread wheel constructed from ASTM A36 carbon steel, mounted on a SAE 1045 medium carbon steel hub. The assembly includes a sealed ball bearing pre-installed. Industrial enamel coating protects against corrosion and wear.
Q: Which Mobile pallet jack models are compatible with the MO 120E8S-A?
A: The MO 120E8S-A is designed for Mobile manual pallet jack ECO I-55 series. Related model designations include ECO I55 and ECO I 55. Confirm your equipment model before ordering to ensure proper fitment.
Q: Why choose a steel steer wheel over nylon or polyurethane alternatives?
A: Steel wheels withstand extreme impact, abrasion, and heavy use better than softer materials. They perform well in rough warehouse environments, outdoor storage areas, and facilities with uneven or debris-laden floors. Steel does not flatten or degrade under sustained load like nylon, and delivers consistent steering control over the wheel lifecycle.
Q: Does the MO 120E8S-A marking create an issue on finished warehouse floors?
A: Yes, steel wheels mark concrete and polished floors. If floor protection is important, consider nylon alternatives like the MO 120E8N-A. The MO 120E8S-A is best suited for rough warehouse floors, industrial areas, outdoor applications, or facilities where floor marking is not a concern.
Q: What is the expected cycle life of the MO 120E8S-A in heavy-use warehouse operations?
A: The MO 120E8S-A is engineered for a minimum expected 50,000 manual steering cycles under normal operating conditions. ASTM A36 and SAE 1045 steel construction, combined with sealed ball bearings and industrial enamel finish, supports extended service life in demanding applications. Harsh impacts, extreme temperatures, or saltwater exposure may reduce this estimate. Replace when the sealed bearing develops play or the wheel surface becomes severely gouged.
