Frequently Asked Questions
Q: What is the exact wheel diameter and tread width of the SU S653?
A: The SU S653 has an outside diameter of 5.000 inches and a tread width of 2.875 inches. The bore diameter is 1.87 inches, hub width is 2.875 inches, and wheel diameter (the actual rotating component) is 3 inches. Bore depth is 0.591 inches and bore outer diameter is 2.045 inches. Always verify these dimensions against your jack assembly before ordering.
Q: Is the SU S653 a direct replacement for Superior or other brand load wheels?
A: The SU S653 is equivalent to Superior and other 5-inch diameter, 2.875-inch width load wheels. However, verify bore diameter (1.87 inches) and hub width match your existing setup. Some competitors use different bore sizes or hub configurations. Always measure your current wheel bore and axle diameter before substituting.
Q: What does Shore A 95 hardness mean for the SU S653 tread?
A: Shore A 95 is a durometer rating that measures polyurethane tread hardness. Higher numbers indicate harder, more wear-resistant tread but with slightly less grip. Shore A 95 provides balanced wear life and floor grip for general material handling. If you need more grip, request a lower hardness (Shore A 90). If you need maximum wear life, upgrade to Shore A 97 or higher (such as the SU S653 XL).
Q: What is the static load rating of the SU S653?
A: The SU S653 is rated for 250 pounds static load per wheel. This assumes proper bearing installation and jack weight distribution across all four wheels. Do not exceed this limit, as overloading causes premature bearing wear, hub fatigue, and tread separation. For applications requiring higher load capacity, evaluate the SU S653 XL (higher hardness) or consult load capacity data for your specific jack model.
Q: Are the sealed ball bearings in the SU S653 serviceable?
A: The SU S653 uses sealed ball bearings that are not designed for field service or re-lubrication. If a bearing fails or seizes, replace the entire wheel assembly. Do not attempt to disassemble, clean, or repack sealed bearings. Attempting to service sealed bearings voids the warranty and risks bearing damage and wheel wobble.
