Frequently Asked Questions
Q: What are the diameter and width dimensions of the SU S457-XL load wheel?
A: The SU S457-XL is a standard electric lift truck load wheel. Confirm the exact diameter and width by checking your truck manual or the original wheel markings. Typically, load wheels range from 4 to 6 inches in diameter. If the specification is not marked on the wheel itself, contact your truck manufacturer or dealer with the truck serial number.
Q: Can I substitute the SU S457-XL with a different brand load wheel?
A: You can substitute a different brand load wheel only if it matches the bore diameter, width, and axle configuration of the SU S457-XL. Mismatches in bore size or width will cause binding, axle damage, or unsafe truck operation. Always measure your existing wheel or axle shaft before purchasing a replacement.
Q: How do I know if the SU S457-XL wheel needs replacement?
A: Replace the SU S457-XL when you observe flats or grooves in the tread, visible cracking in the polyurethane, chunks missing from the wheel edge, or if the wheel no longer rolls straight. If the wheel is out of round, the truck will vibrate during operation and the axle bearing will fail prematurely. Do not attempt to repair polyurethane wheels—replacement is required.
Q: What hardness rating does the SU S457-XL wheel have?
A: The SU S457-XL is a load wheel for electric lift trucks, typically made from polyurethane. The exact Shore A hardness (durometer) should be verified by checking the wheel label or your truck documentation. Harder wheels (95-98A) are more durable but less forgiving on shock loads. Softer wheels (85-92A) absorb more impact but wear faster.
Q: Do I need any special tools to install the SU S457-XL on my lift truck?
A: Most load wheel installations require only a basic socket set to remove fasteners if present. Slide the old wheel off the axle shaft and slide the new SU S457-XL on. If the wheel is stuck, use a rubber mallet to gently tap it free—do not strike the polyurethane directly. Verify the wheel seats fully against any spacers or mounting flanges before operating.
