Frequently Asked Questions
Q: What are the exact dimensions of the SU S524 load wheel?
A: The SU S524 is 3.375 inches in diameter by 3.97 inches in width. Use these dimensions to verify clearance against your truck frame and fork carriage. Measure your current wheel to confirm size before ordering. If your truck manual specifies a different size (such as 3.25 inch or 4 inch), do not substitute the SU S524.
Q: Is the SU S524 a direct replacement for my current load wheel, or will I need to modify anything?
A: The SU S524 will fit any lift truck wheel hub with a 20 mm bore that accommodates the 3.375 x 3.97 inch size. Check your axle width and hub material (typically ductile iron or aluminum). If your truck uses a different bore size (15 mm, 25 mm, etc.), the SU S524 will not fit. Verify with your truck OEM documentation or existing wheel before purchase.
Q: What is the rated load capacity per wheel for the SU S524?
A: Load capacity depends on wheel hardness and the number of wheels under the load (typically 4 wheels on a standard lift truck). The SU S524 standard polyurethane formulation typically carries 500 to 700 pounds per wheel at rated hardness. Consult your truck manual for total rated load and divide by wheel count to confirm per-wheel capacity. Never exceed the truck nameplate rating.
