Frequently Asked Questions
Q: What does the EZ designation mean on the SU 9133-EZ-A load wheel assembly?
A: The EZ designation refers to a high-traction polyurethane compound engineered specifically for material handling equipment in general applications as well as wet floors and cold storage environments. EZ does not mean easy install or easy replacement. The EZ compound provides enhanced grip and traction on contaminated or moisture-exposed surfaces compared to standard polyurethane, making it ideal for freezers, dock areas, and environments where slip resistance is critical.
Q: What are the specifications and cross-reference part numbers for the SU 9133-EZ-A?
A: The SU 9133-EZ-A is a 3.25 inch diameter load wheel assembly with cast polyurethane construction using a mid-market compound optimized for reduced rolling resistance and exceptional cold weather performance. The OEM part number is L309133. Cross-reference equivalent parts include SU 9133-XL-A, SU S9133-XL-A, and SUS9133-EZ. This assembly is suitable for heavy-duty and continuous industrial fleet environments.
Q: Is the SU 9133-EZ-A interchangeable with the SU 9133-XL-A?
A: Yes, the SU 9133-EZ-A is directly interchangeable with SU 9133-XL-A, SU S9133-XL-A, and SUS9133-EZ. These part numbers represent the same or equivalent assemblies. The SU 9133-EZ-A features the high-traction EZ polyurethane compound, while the XL variant uses a different hardness specification. Verify your existing wheel bore and dimensions match before substituting to ensure proper fit. If you need a specific compound type for your application (wet floor, cold storage, or dry surface), confirm the compound designation when ordering.
Q: What equipment brands use the SU 9133-EZ-A load wheel assembly?
A: The SU 9133-EZ-A is compatible with electric lift trucks and material handling equipment from Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, Linde, Clark, Mitsubishi, CAT, and BT. This 3.25 inch wheel is commonly used on smaller load-wheel positions or on compact lift truck models. Always check your truck documentation or measure your existing wheel bore to confirm the SU 9133-EZ-A matches your equipment specifications.
Q: Why is the SU 9133-EZ-A recommended for cold storage and wet environments?
A: The SU 9133-EZ-A high-traction polyurethane compound maintains grip and traction on wet, icy, or oily floors that would cause standard polyurethane wheels to slip. The mid-market formulation resists hardening in cold storage temperatures below 32 degrees Fahrenheit, while standard compounds become brittle and lose traction. Reduced rolling resistance means electric trucks use less battery power in these harsh environments. The high-traction profile also resists hydroplaning on wet dock areas. For warehouses, freezers, or outdoor loading zones, the SU 9133-EZ-A provides safer equipment control and longer service life than standard polyurethane wheels.
