Frequently Asked Questions
Q: What does the -EZ designation mean on the SU S9142-EZ wheel?
A: The -EZ suffix does NOT indicate easy installation or easy replacement. EZ designates a High Traction polyurethane compound formulated specifically for material handling equipment operating on wet floors and in cold storage environments. This compound provides superior grip and does not become brittle at low temperatures. Use SU S9142-EZ wheels when your pallet jack or electric lift truck regularly operates in freezer units, wet warehouses, or outdoor wet conditions.
Q: Can I use SU S9142-EZ wheels on a standard dry warehouse pallet jack?
A: Yes, SU S9142-EZ wheels are compatible with any 4 x 2 wheel application and will work on standard pallet jacks. However, the High Traction polyurethane compound is optimized for wet and cold environments. In typical dry warehouse conditions, standard SU S9142-A wheels offer better wear life and lower rolling resistance. Choose the product matched to your primary operating environment for optimal performance and cost efficiency.
Q: How do SU S9142-EZ wheels perform on frozen concrete or icy surfaces?
A: SU S9142-EZ wheels maintain traction on cold surfaces because the High Traction polyurethane compound does not harden in sub-zero temperatures. Standard polyurethane wheels become rigid and slippery below freezing. However, no wheel provides complete safety on ice. Reduce load weight, lower operating speed, and ensure the lift truck has adequate ground clearance to prevent contact with ice buildup on floor or wheel hubs when working in extreme cold.
Q: What is the typical lifespan of SU S9142-EZ wheels in wet storage?
A: SU S9142-EZ wheels typically operate 1500 to 2500 operating hours in wet environments before tread degradation becomes noticeable, depending on load weight and floor surface texture. Inspect wheels monthly for tread depth loss, flat spots, or edge damage. Wet operations accelerate wear due to increased friction and moisture absorption into the polyurethane. Replace when tread depth falls below 3/16 inch or when visible cracks develop in the compound.
Q: Do SU S9142-EZ wheels require different maintenance than standard wheels?
A: Maintenance is identical to standard wheels. Inspect bearings every 200 operating hours for play or noise. If the assembly uses grease-packed bearings, apply lightweight lithium grease annually or when bearing play develops. Wash wheels with mild detergent and dry thoroughly after extended wet storage work to prevent salt corrosion of the steel hub if your facility uses de-icing salts. Check wheel mounting bolts monthly in high-vibration applications.
Q: Are there equivalent part numbers for the SU S9142-EZ?
A: SU S9142-EZ is a Superior-branded wheel assembly. Many OEM manufacturers produce equivalent high-traction wheels for wet and cold applications under their own SKUs. To find cross-references, provide your equipment model, serial range, and wheel bore diameter. Compatible manufacturers include Crown, Toyota, Raymond, Yale, Hyster, and others. Always verify the polyurethane compound specification matches your environment before substituting.
