Frequently Asked Questions
Q: What are the exact dimensions of the SU 459 wheel?
A: The SU 459 is 6 inches in outer diameter by 3 inches in width. The bore is 2.25 inches inside diameter with a 0.78 inch bore depth and 2.4404 inch bore outside diameter. In metric, the wheel is 152.40 mm diameter by 76.20 mm width. The tread profile is a 3/8 inch radius.
Q: What material is the SU 459 made from and is it different from smaller wheel models?
A: The SU 459 is made from Cushothane XL material, a durable elastomer compound. Cushothane XL provides good grip on wet and dry floors while resisting heat and oils common in industrial settings. Smaller 3.38 inch wheels like the SU 448-XL use polyurethane instead, so they are not interchangeable materials or performance profiles.
Q: Can the SU 459 wheel be used on any electric lift truck or are there fitment restrictions?
A: The SU 459 is designed for specific electric lift truck models. The 6 inch diameter and 2.25 inch bore require a compatible axle and frame. Do not assume the SU 459 fits your truck just because it is a larger wheel. Verify the original part number on your equipment or contact the manufacturer with your lift truck serial number before ordering.
Q: What load capacity is the SU 459 wheel rated for in pounds?
A: The load capacity for the SU 459 is not published in manufacturer sources. This is a load wheel, not a drive wheel, so it carries weight but does not propel the truck. Your lift truck nameplate specifies the maximum load. Never exceed the truck load rating regardless of wheel specifications.
Q: How do I know if my SU 459 wheel needs replacement?
A: Replace the SU 459 wheel if you observe cracks in the tread, chunks of Cushothane missing, uneven wear patterns, flat spots, or the wheel wobbles during operation. Also replace if the wheel makes noise or drags when the truck is being steered. A wheel that is no longer round or that shows exposed bore material has failed and is unsafe.
