POLY LOAD WHEEL 95A
Frequently Asked Questions
Q: What does the 95A designation mean for the SU S366 poly load wheel?
A: The 95A refers to the durometer hardness of the polyurethane material. 95A is a medium-hard compound that provides good grip and moderate load capacity with reasonable floor protection. A higher durometer (like 98A) would be harder and last longer but provide less grip. A lower durometer (like 90A) would provide more grip but wear faster. The 95A offers a balance for general warehouse use.
Q: Is the SU S366 poly wheel interchangeable with Cushothane SU S358?
A: Do not assume direct interchangeability. While both are polyurethane-based wheels, the SU S366 and SU S358 have different durometer ratings, material formulations, load ratings, and likely different outer diameters or widths. Verify the exact dimensions and bore specifications before substituting. Using the wrong wheel can cause binding, bearing damage, or load control issues.
Q: What surfaces is the SU S366 poly load wheel best suited for?
A: The SU S366 poly 95A wheel performs well on smooth to moderately rough concrete floors common in warehouses, manufacturing plants, and distribution centers. It is not recommended for wet surfaces, oily floors, or chemical-contaminated areas as polyurethane can swell and deteriorate. Do not use on outdoor asphalt or gravel. If your environment has special surface conditions, consult the product datasheet for compatibility.
Q: How do I determine if a SU S366 wheel has reached end of life?
A: Replace the SU S366 wheel when you observe flat spotting, visible cracks, chunks missing from the tread perimeter, permanent set deformation that does not recover, or a glazed appearance. If the truck slips on dry floors or spins wheels easily, traction is lost and replacement is needed. If grinding, squeaking, or clicking occurs during operation, the bearing may be damaged from a worn wheel and both should be replaced.
Q: Can I apply a tread coating or recondition the SU S366 wheel instead of replacing it?
A: Polyurethane wheels cannot be reconditioned by grinding or applying traction coatings in the field. Do not attempt to restore grip by sanding the tread surface as this causes uneven wear and reduces the wheel diameter. Once traction is lost, the wheel must be replaced. Field repair kits are not available for SU S366 wheels and will void the warranty.
Q: How should the SU S366 poly wheel be stored before installation?
A: Store the SU S366 wheel in a cool, dry location away from direct sunlight, heat sources, and chemicals. Avoid exposure to oil, solvents, or battery acid as these can damage polyurethane. Do not store wheels stacked for extended periods as the weight can cause permanent deformation. Keep wheels in original packaging or on a horizontal rack. Inspect for cracks or hardening before installation if stored longer than 12 months.
