MO 203M

Frequently Asked Questions

Q: What does the MO 203M part specification 2 X 3 X 1.575/.450 P/S indicate?
A: The dimensions 2 X 3 X 1.575/.450 P/S represent critical bearing or seal component geometry. The 2 inch and 3 inch measurements define outer and inner diameters, while 1.575 inch and .450 inch define the thickness and seal pocket depth. P/S notation indicates polymer seal construction.

Q: What Mobile pallet jack model uses the MO 203M component?
A: The MO 203M is compatible with Mobile manual pallet jack model 2X3X1.575/.450PS. Match your equipment specification exactly before ordering.

Q: What function does this component serve in a Mobile pallet jack?
A: Based on dimensions and polymer seal notation, the MO 203M functions as a bearing seal or load wheel seal assembly. It protects bearing surfaces or wheel assemblies from contamination, water, and dirt ingress while enabling smooth rotation under load.

Q: How often should the MO 203M seal be inspected or replaced?
A: Inspect the MO 203M polymer seal during routine equipment maintenance. Replace if you observe cracks, hardening, discoloration, or evidence of fluid leakage. Damaged seals allow hydraulic fluid loss and contamination, degrading bearing or wheel performance.

Q: What is the polymer seal material advantage in this component?
A: Polymer seals provide flexibility and resilience at varying temperatures, resist oils and hydraulic fluids, and accommodate minor wear without losing sealing integrity. Polymer materials tolerate thermal cycling in warehouse and cold storage environments better than rigid elastomers.
