Frequently Asked Questions
Q: What are the specifications of the SU S149-XL load wheel assembly?
A: The SU S149-XL has a 4.000-inch outside diameter and 2.375-inch width (4 x 2.375 or 101.60 x 60.32 millimeters). It features polyurethane tread bonded to a steel core with Shore A 95 hardness. The assembly is machined steel core with polyurethane overmold. It is designed for heavy-load and frequent-cycle applications on electric lift trucks. Tread width is 4.25 inches for stability.
Q: How does the SU S149-XL compare to the SU S143-XL?
A: Both wheels have the same 4.000-inch outside diameter, but the SU S149-XL is narrower at 2.375 inches compared to the SU S143-XL at 2.750 inches. The SU S149-XL uses polyurethane bonded to steel core versus Cushothane XL on the S143-XL. The SU S149-XL offers enhanced load distribution and is better for heavy-cycle use. Do not mix these wheels on the same truck, as the width difference affects handling.
Q: What load can the SU S149-XL wheel handle?
A: The SU S149-XL is engineered for high-cycle, heavy-load environments. Exact load capacity depends on your lift truck model and the number of wheels. The polyurethane construction and steel core provide durability for frequent use. Consult your truck documentation for maximum load per wheel. Exceeding rated load or operating continuously at maximum capacity reduces wheel lifespan significantly.
Q: Is the SU S149-XL installation tool-free?
A: Yes, installation is plug and play if you are replacing a wheel of the same diameter and bore size. Lift the truck, remove the fastener, slide off the old wheel, insert the new SU S149-XL, and tighten the fastener. No special tools are required. Verify the wheel spins freely after installation. If the bore does not fit your axle or the width creates clearance issues, do not attempt installation.
Q: What maintenance does the SU S149-XL require?
A: Inspect the SU S149-XL weekly for tread wear, flat spots, or cracks, especially in high-use environments. Check bearing condition by lifting the wheel and spinning it by hand, listening for grinding. Clean debris from the tread. Replace if you notice uneven wear, torn tread, or bearing noise. The polyurethane-to-steel bond can fail if exposed to extreme temperatures or solvents, so keep wheels dry and clean.
Q: How long will the SU S149-XL last with heavy daily use?
A: With heavy daily use, the SU S149-XL typically lasts 1 to 3 years. Polyurethane tread wears faster under frequent high-load cycles. Service life depends on load weight, floor surface, operating hours, and maintenance. Clean inspection and early bearing maintenance can extend service life. If your truck operates 8 or more hours daily at maximum load, expect wheel replacement every 12 to 24 months.
