Frequently Asked Questions
Q: What material is the SU S358 wheel made from and why does it matter?
A: The SU S358 is constructed from Cushothane, a polyurethane elastomer that provides good grip and shock absorption. This material resists oil, mild chemicals, and moisture better than natural rubber. It performs well on smooth warehouse floors and does not deteriorate quickly when exposed to forklift battery acid spills. Cushothane wheels are ideal for indoor electric lift truck operations.
Q: Are SU S358 wheels equivalent to any other brand load wheels?
A: SU S358 is a direct replacement for same-model Yale and Hyster lift trucks that originally used Cushothane 5 x 5 wheels. Cross-reference your truck serial number range and original part number. Do not assume interchangeability based on size alone. Verify the hub width, bore diameter, and mounting snap ring size match before ordering as a substitute.
Q: Can I upgrade from SU S353-XL to SU S358 wheels?
A: No. The SU S358 is 5.000 inches wide while the S353-XL is only 3.625 inches wide. Installing the wider S358 will cause frame interference, binding against the steering mast, or contact with load backrest. The wheelbase geometry is engineered for the original width. Always maintain the exact width specification of your original equipment.
Q: How often should SU S358 wheels be inspected and what should I look for?
A: Inspect wheels monthly or every 40 hours of operation, whichever comes first. Look for flat spots, chunks missing from the tread, permanent set deformation, cracking, or glazing. Test for play at the axle bearing. Cushothane can become hardened and glazed in low-temperature storage, reducing grip. If the truck slips or spins wheels on dry concrete, the tread may be deteriorated and require replacement.
Q: What is the typical lifespan of a SU S358 wheel in normal warehouse use?
A: In typical indoor warehouse conditions, a SU S358 wheel lasts 2 to 4 years depending on usage intensity and floor conditions. High-cycle operations or operation on rough concrete may reduce life to 1 to 2 years. Proper tire pressure, regular wheel alignment, and clean floor surfaces extend wheel life. Track total operating hours and inspect quarterly to plan replacement before failure.
Q: Do I need to apply grease to SU S358 wheel bearings during installation?
A: Yes. Before installing a new SU S358 wheel, apply a light coat of lithium-based wheel bearing grease to the axle shaft and bore area. Do not over-grease as excess lubricant can attract dirt and cause drag. Use only grease compatible with Cushothane materials. Sealed or shielded bearings do not require re-greasing during the wheel life.
