Frequently Asked Questions
Q: Is SU 654 the correct width replacement for my pallet jack with 3.625 inch wheel spacing?
A: Yes. SU 654 measures exactly 5.000 inch diameter by 3.625 inch width and fits all standard pallet jacks manufactured since 2008 with 3.625 width frame configuration. The 2.188 inch inside diameter and 0.67 inch bore depth match industry-standard axle sizes. Verify your current wheel width before ordering - this part is not compatible with 2.875 width frames (use SU 653-XL instead).
Q: What does non-marking polyurethane mean and will SU 654 stain my warehouse floor?
A: Non-marking indicates the polyurethane formulation does not transfer dark residue or tire marks onto flooring. SU 654 is safe for food-grade, pharmaceutical, and cleanroom environments where floor marking would be a compliance violation. The 95A durometer rating balances grip and wear resistance for general warehouse use. Do not confuse non-marking wheels with non-staining - hot rubber can still leave faint marks on light-colored floors under extreme conditions.
Q: How long do sealed precision bearings last on SU 654 wheels and can they be serviced?
A: Sealed bearings on SU 654 typically last 20-24 months under continuous 8-hour daily use. They are not serviceable - repacking or relubrication voids the seal and introduces contamination. If a bearing fails, replace the entire wheel assembly; bearing replacement labor typically costs more than a new wheel. Lifespan extends to 30+ months if the truck operates in dry conditions below 100 degrees Fahrenheit and load capacity is not exceeded.
