Frequently Asked Questions
Q: What does the EZ designation mean on the SU S9144-EZ wheel?
A: The EZ designation indicates this wheel uses a High Traction polyurethane compound specifically engineered for wet floors, cold storage environments, and general material handling applications. EZ does not refer to easy installation or easy replacement. The High Traction compound provides superior grip and traction on slippery surfaces compared to standard polyurethane wheels.
Q: What are the specifications and performance characteristics of the SU S9144-EZ?
A: The SU S9144-EZ is a 3.25-inch outer diameter by 4.5-inch width wheel with a 1.938-inch bore and 0.512-inch bore depth. The wheel features High Traction Cushothane XL polyurethane tread material and a steel hub. Metric equivalent is 82.55mm diameter by 114.30mm width. The High Traction compound provides improved skid resistance and maintains flexibility in temperatures as low as minus 20 degrees Fahrenheit, making it suitable for cold storage and freezer applications.
Q: Is the SU S9144-EZ suitable for wet floors and cold storage environments?
A: Yes, the SU S9144-EZ is designed for wet floors and cold storage. The High Traction polyurethane compound is formulated to resist slipping on water, ice, and condensation. The material remains flexible in sub-zero temperatures without becoming brittle. If your equipment operates in freezers, coolers, or on regularly wet floors, the SU S9144-EZ provides superior traction and reliability compared to standard polyurethane wheels.
Q: How does the SU S9144-EZ differ from the SU S9144 XL wheel?
A: The SU S9144 XL uses standard polyurethane tread optimized for normal indoor warehouse environments and features XL3 bonding technology for durability. The SU S9144-EZ uses High Traction polyurethane optimized for wet and cold environments. If your equipment operates primarily in dry, room-temperature warehouses, choose the SU S9144 XL. If your equipment operates in freezers, coolers, or on wet surfaces, choose the SU S9144-EZ.
Q: What maintenance is required for the SU S9144-EZ in cold storage?
A: In cold storage, inspect the wheel for ice buildup or frost accumulation and remove it with a brush or scraper before operation, as ice reduces traction. Check bearings monthly, as low temperatures can cause bearing lubricant to thicken and reduce rolling efficiency. Ensure fasteners are tight, as thermal contraction and expansion from temperature cycling can loosen bolts. Replace the wheel if the tread becomes hard or brittle, which indicates material degradation from prolonged cold exposure.
Q: Can the SU S9144-EZ be used in standard room-temperature environments?
A: Yes, the SU S9144-EZ can be used in standard room-temperature environments and will perform reliably. However, it is optimized for wet and cold conditions, so if your equipment operates only in dry, temperature-controlled warehouses, the standard SU S9144 XL may offer better value without sacrificing performance. Use the SU S9144-EZ if your equipment operates in multiple environments that include cold or wet areas.
