Frequently Asked Questions
Q: What are the exact dimensions of the SU 9143 load wheel?
A: The SU 9143 is a 4.000 inch diameter x 2.500 inch width wheel (also called 4 x 2.5 or 101.60mm x 63.50mm). Bore diameter is 2.0467 inches with a 0.591 inch bore depth. Hub width is 2.5 inches. These dimensions are standard for electric lift truck applications and fit most Yale, Crown, and Hyster models with compatible wheel hubs.
Q: What material is the SU 9143 wheel made from?
A: The SU 9143 uses Cushothane XL, a premium polyurethane compound designed for industrial material handling. Cushothane XL offers excellent wear resistance, non-marking properties, and performance across varied floor surfaces including concrete, tile, and warehouse floors.
Q: Is the SU 9143 a complete wheel assembly or just the wheel?
A: The SU 9143 is the wheel component only. It is not a complete assembly. If you need a ready-to-install assembly with bearings and hardware pre-mounted, order the SU 9143-A or SU 9143-XL-A instead.
Q: What tread profile does the SU 9143 have?
A: The SU 9143 features a 3/8 inch radius tread profile. This design provides smooth rolling, reduces noise, and minimizes floor marking on most surfaces. The tread is suitable for both smooth and slightly textured warehouse floors.
Q: Can I use the SU 9143 on a pallet jack that previously used a different wheel?
A: Yes, as long as the original wheel bore diameter and hub width match. The SU 9143 has a 2.0467 inch bore diameter and 2.5 inch hub width. Verify these dimensions against your current wheel or jack documentation. If bore or width differs, the wheel will not press fit properly and can cause steering or stability issues.
Q: How long does the SU 9143 wheel typically last in heavy-duty service?
A: Lifespan depends on load, surface, and hours of operation. In normal warehouse conditions (8-12 hour daily shifts, moderate loads), Cushothane XL wheels typically last 18-36 months before tread wears to replacement thickness. Rough concrete, high-load operations, or outdoor use reduces lifespan. Inspect wheels quarterly for uneven wear or flat spots.
