Frequently Asked Questions
Q: What is Cushothane XL and how does it differ from standard polyurethane?
A: Cushothane XL is a proprietary polyurethane compound engineered for durability and traction in material handling applications. It resists compression set (permanent deformation) better than standard polyurethane, maintains traction on concrete and vinyl floors, and resists mild oil and chemical contact. Compared to standard polyurethane, Cushothane XL offers extended wheel life, reduced flat-spotting, and better performance in ambient temperatures between 32 and 85 degrees Fahrenheit.
Q: What are the exact dimensions and bore specifications of the SU S9812?
A: The SU S9812 has an outside diameter of 3.25 inches (82.55 mm), a width of 6.01 inches (152.65 mm), an inside diameter of 1.938 inches, and a bore depth of 0.584 inches. The bore outside diameter is 2.0467 inches. These specifications fit standard electric pallet jack and lift truck axles. Verify your axle bore size and hub width before ordering to confirm fitment.
Q: What is the difference between SU S9812 and SU S9812-A?
A: The SU S9812 is a solid wheel with no bearings; it mounts directly on the axle. The SU S9812-A includes greaseable bearings and a polyurethane compound 306 with 97A Shore hardness, allowing longer service intervals and easier maintenance. If your truck does not currently have bearing-equipped wheels, you can upgrade to SU S9812-A if axle clearance permits. For heavy-duty applications with frequent use, the bearing version (SU S9812-A) is recommended.
Q: Can I use the SU S9812 on wet floors or in cold storage?
A: The SU S9812 with Cushothane XL compound is suitable for standard warehouse floors and light-to-moderate moisture conditions. However, it is not designed for wet floors where standing water is present or for cold storage below 32 degrees Fahrenheit. In cold environments, Cushothane XL hardens and traction diminishes. For wet or cold applications, consult us to identify a wheel with high traction polyurethane compound formulated for those environments.
Q: How long does the SU S9812 wheel typically last before replacement?
A: The SU S9812 wheel with Cushothane XL typically lasts 2,000 to 3,500 operating hours on standard concrete floors with typical pallet jack loads. Rough floors, higher loads, or faster operating speeds reduce life. Replace the wheel when tread shows flat spots, chunks break away, or the wheel develops a visible flat side. Regular visual inspection every 500 hours helps catch wear early and prevents sudden failure.
Q: What tools do I need to install the SU S9812 wheel?
A: Installation requires basic hand tools: a mallet or dead-blow hammer to tap the wheel on or off, and possibly a socket wrench for the axle nut or pin. If the axle bore is rusty or corroded, apply penetrating oil 15 minutes before attempting removal. Tap the wheel straight off and slide the new SU S9812 on, ensuring it seats fully. Do not force the wheel; if resistance is high, the axle bore may need cleaning or inspection for damage.
