LOAD WHEEL 5X2 EZ 87A
Frequently Asked Questions
Q: What does the EZ designation mean on the SU S9123-EZ load wheel?
A: EZ indicates an easy-to-install or ergonomic design. The SU S9123-EZ is a 5X2 load wheel with 87A durometer compound. The EZ variant typically features quick-release axle pins or simplified mounting to reduce installation time. Confirm your truck accepts EZ axle styles before ordering.
Q: Is the SU S9123-EZ 5X2 wheel compatible with standard 5-inch hubs?
A: The SU S9123-EZ is a 5-inch diameter wheel with a 2-inch width. Verify hub bore diameter and keyway size match your truck axle. The 87A durometer is a mid-range polyurethane hardness suitable for indoor concrete floors. If your truck requires a different hardness (73A, 95A), order the equivalent wheel in your needed durometer.
Q: How do I know if the SU S9123-EZ wheel needs replacement?
A: Replace the wheel if tread is worn to 1/16 inch depth, if polyurethane shows flat spots or chunks missing, if the wheel does not rotate freely or exhibits grinding noise, or if bearing play exceeds 1/8 inch radial movement. Hardened or glazed polyurethane indicates age and loss of grip even if visible tread remains.
Q: What is the operating temperature range for the SU S9123-EZ wheel?
A: Standard polyurethane wheels operate reliably between 32 and 120 degrees Fahrenheit. Below 32 degrees, polyurethane becomes rigid and loses traction. Above 120 degrees, material begins to soften and accelerates wear. Cold storage or hot warehouse environments may require higher-durometer wheels for consistent performance.
Q: Can I use the SU S9123-EZ wheel on both hard and soft floors?
A: The 87A durometer is optimized for hard concrete floors. Do not use on wood, vinyl, or tile floors as the hardness will cause slipping. For soft or uneven floors, use a softer durometer such as 73A. Using incorrect hardness causes safety hazards and does not properly grip the floor.
Q: What is the typical lifespan of the SU S9123-EZ wheel under normal use?
A: Expected lifespan is 18 to 36 months under normal warehouse duty. Heavy use, sharp turns, or rough floor conditions reduce lifespan to 12 months. Monthly inspection and removal of debris extends service life. Replace wheels as a set when one wheel wears significantly to ensure balanced tracking and prevent steering problems.
