Frequently Asked Questions
Q: What is the difference between MO 120E4 and MO 120E4-SS?
A: Both are precision thrust bearings for Mobile ECO I-55 manual pallet jacks with identical dimensions: 51 mm outer diameter x 28 mm inner diameter x 15 mm width. The MO 120E4-SS uses stainless steel construction for superior corrosion resistance in wet, humid, and cold storage applications. The standard MO 120E4 is standard steel construction.
Q: When should I use the MO 120E4-SS instead of the standard MO 120E4?
A: The MO 120E4-SS is recommended for wet or humidity-exposed environments, cold storage operations, outdoor use, or where moisture contact is frequent. The stainless steel material prevents rust and bearing degradation. For standard indoor, dry warehouse environments, the standard MO 120E4 is sufficient and more cost-effective.
Q: What are the dimensions of the MO 120E4-SS?
A: The MO 120E4-SS has an outer diameter of 51 mm, an inner diameter of 28 mm, and a width of 15 mm. These dimensions are identical to the standard MO 120E4. Confirm your equipment bore specifications match before ordering.
Q: What equipment is the MO 120E4-SS compatible with?
A: The MO 120E4-SS fits Mobile pallet jacks, specifically the ECO I-55 model. Alternate model designations are ECO I55 and ECO I 55. No cross-reference equivalents for other brands have been identified.
Q: Is the stainless steel bearing more durable than the standard bearing?
A: In corrosive environments (wet, salty, cold storage), stainless steel resists oxidation and extends bearing life significantly. In standard dry conditions, both materials perform comparably. Load capacity and mechanical performance ratings are not publicly available from Mobile documentation. Choose the material type based on your operating environment.
