Frequently Asked Questions
Q: What are the exact specifications of the SU 9143-XL?
A: The SU 9143-XL is a 4.000 inch diameter x 2.500 inch width wheel with a polyurethane, non-marking tread and polyurethane hub. Bore diameter is 2.0467 inches with a 0.591 inch bore depth. Inside diameter is 1.938 inches. Tread profile is 1/4 inch radius. The wheel uses Cushothane XL material for superior durability and long-life performance.
Q: Is the SU 9143-XL suitable for outdoor use or wet floors?
A: The SU 9143-XL non-marking polyurethane tread provides good traction on wet concrete and damp floors, but it is not optimized for continuous outdoor exposure or standing water. For outdoor dock operations, consider the SU 9143-XL-A, which includes sealed bearings and a steel hub for better weather resistance.
Q: What is the difference between the 1/4 inch radius tread and 3/8 inch radius tread?
A: The SU 9143-XL has a 1/4 inch radius tread, while the standard SU 9143 has a 3/8 inch radius. A smaller radius (1/4 inch) creates slightly more tread definition and edge grip, which can improve traction on smoother or more slippery surfaces. A larger radius (3/8 inch) rolls more smoothly but may reduce grip in certain conditions. Choose based on your floor type and load requirements.
Q: Can the SU 9143-XL be used as a direct replacement for other 4 x 2.5 wheels?
A: Yes, as long as your equipment has a 2.0467 inch bore diameter and 2.5 inch hub width. The SU 9143-XL is dimensionally compatible with most electric lift truck wheel hubs manufactured to standard material handling specifications. However, always verify bore and hub measurements on your current wheel or consult the equipment manual.
Q: How do I know if the SU 9143-XL includes bearings or if I need to install my own?
A: The SU 9143-XL is a wheel component only. It does not come with pre-installed bearings. You must have your own sealed or open bearings ready for installation. If you need a complete ready-to-install wheel assembly with bearings included, order the SU 9143-XL-A instead, which comes with pre-pressed precision bearings.
Q: What durometer rating does the SU 9143-XL have?
A: The SU 9143-XL specifications do not explicitly list a durometer rating in the technical data. However, Cushothane XL material typically rates between 90A and 97A durometer. For an exact durometer specification, contact the manufacturer. If durometer rating is critical to your application, the SU 9143-XL-A specifies a 97A durometer rating and may be a better choice.
