Frequently Asked Questions
Q: What are the SU 9144-EZ dimensions?
A: The SU 9144-EZ is 3.250 inches in outside diameter and 4.500 inches in width. In metric, this is 82.55 mm x 114.30 mm. The bore inside diameter is 1.938 inches, bore depth is 0.512 inches, and bore outside diameter is 2.1649 inches. Confirm these measurements match your electric lift truck spindle and frame before installation.
Q: What does the EZ compound mean on the SU 9144-EZ?
A: The EZ designation indicates a High Traction polyurethane compound formulated for wet floors, cold storage, and general material handling applications. This is a material specification, not an installation ease marker. The EZ compound provides superior grip and durability in challenging environmental conditions compared to standard polyurethane.
Q: How does the SU 9144-EZ compare to other load wheels?
A: The SU 9144-EZ is a narrower wheel (4.500 inch width) than the SU 9141-XL-A (6.500 inch width) but matches the 3.250 inch diameter. The EZ compound is specifically for wet and cold environments. If your equipment nameplate calls for a 3.25 x 4.5 inch load wheel with high-traction properties, the SU 9144-EZ is your match. Do not substitute without verifying frame geometry and load rating.
Q: Is the SU 9144-EZ suitable for refrigerated warehouses?
A: Yes. The SU 9144-EZ is engineered for cold storage operation. The High Traction polyurethane maintains flexibility and grip at low temperatures where standard polyurethane becomes brittle and loses traction. If you operate your electric lift truck in freezer or refrigerated environments, the EZ designation ensures optimal performance and safety.
Q: What material is the SU 9144-EZ hub made from?
A: The SU 9144-EZ uses Cushothane XL material for the tread over a steel hub construction. Cushothane XL is a premium polyurethane compound engineered for high-traction and extended durability in demanding industrial applications. The steel hub provides load-bearing rigidity and bearing support.
