Frequently Asked Questions
Q: What is the wheel diameter and width of the SU S666-XL?
A: The SU S666-XL is a 6.000 inch diameter by 4.000 inch width poly load wheel (152.40mm x 101.60mm). The bore specifications are 2.5 inch inside diameter with a 2.8341 inch bore outside diameter and 0.68 inch bore depth.
Q: Is the SU S666-XL compatible with my electric pallet truck model?
A: The SU S666-XL is designed for electric lift trucks and electric pallet trucks. Verify your truck application uses a 6 x 4 wheel size (6 inch diameter, 4 inch width) and has a 2.5 inch bore. Check your equipment manual or existing wheel before ordering to confirm the bore diameter and width match.
Q: What is the tread hardness of the SU S666-XL and does it affect performance?
A: The SU S666-XL has a Shore A 97 hardness rating. This harder polyurethane compound provides excellent wear resistance and is ideal for industrial floor conditions with minimal cushioning. The angle tread profile ensures smooth, low-resistance rolling and long service life on warehouse floors.
Q: When should I replace the SU S666-XL wheel?
A: Replace the wheel when you observe flat spots, visible tread wear, chunking, or a diameter reduction of more than 0.25 inch from original specifications. If the truck pulls to one side or loses its smooth rolling motion, inspect both wheels for uneven wear and replace as needed. Polyurethane wheels in high-traffic warehouses typically last 12 to 24 months depending on floor conditions and load frequency.
Q: Can I use the SU S666-XL on wet or oily floors?
A: The polyurethane tread on the SU S666-XL provides good grip on most industrial floors. However, on extremely slick surfaces such as oil-coated concrete or wet floors, traction may reduce. Test the wheel in your specific environment before full deployment. If slipping occurs, consider requesting a higher-durometer wheel or applying floor treatment rather than changing wheel compounds.
