Frequently Asked Questions
Q: What is the bore diameter for the SU 448-XL wheel and will it fit my lift truck axle?
A: The SU 448-XL is a precision load wheel with a 3.38 inch outer diameter and 3.97 inch width. Verify your lift truck axle bore size before ordering, as this wheel is engineered for specific electric pallet truck models. Check your equipment manual or contact the manufacturer with your truck model and serial number range to confirm fitment.
Q: Can I use the SU 448-XL as a replacement for wheels on different electric lift truck brands?
A: The SU 448-XL is a manufacturer-specific part number with no published cross-references to other brands. Do not assume compatibility with other brands or models. Always verify the original part number on your lift truck before ordering. Installing an incorrect wheel size or bore can cause steering problems and unsafe operation.
Q: What load capacity is the SU 448-XL rated for?
A: The rated load capacity for the SU 448-XL is not published in manufacturer sources. This wheel is designed for load wheel position use on select electric models. For duty cycle and weight limits, refer to your lift truck nameplate or operator manual.
Q: What material is the SU 448-XL made from and how long does it typically last?
A: The SU 448-XL has a polyurethane tread bonded to a precision machined steel core. Lifespan depends on operating conditions, floor surface, and maintenance. Expect 12 to 24 months in continuous industrial use. Replace wheels when tread shows uneven wear, cracks, or separation from the core.
Q: Do I need any special tools to replace the SU 448-XL wheel?
A: Wheel replacement requires a wrench or socket to remove the axle fasteners and a way to support the truck safely, such as a jack or blocking. Always lower the load fully and secure the truck before removing wheels. Never work under a lifted truck without proper safety blocks.
