Poly Load Wheel
Frequently Asked Questions
Q: What is the difference between the SU S635 poly load wheel and rubber alternatives?
A: The SU S635 polyurethane wheel resists oils, solvents, and moisture better than rubber. It provides lower rolling resistance, reduces noise, and lasts longer on smooth concrete floors. Rubber wheels work better on rough outdoor surfaces.
Q: Can the SU S635 be used as a replacement for discontinued wheel models?
A: The SU S635 may be compatible with Yale 500114856, Hyster HY 4076524, and Jungheinrich equivalent models depending on your truck series and axle bore diameter. Verify the 1.625-inch bore and 4-inch diameter specification match your current wheel before substituting.
Q: What load rating does the SU S635 poly load wheel support?
A: The SU S635 is rated for 3000-4000 lbs per wheel depending on bearing type and installation configuration. Do not use on trucks rated above 6000 lbs total capacity as this will cause bearing seizure and wheel failure.
Q: How do I diagnose if the SU S635 wheel needs replacement?
A: Replace the SU S635 when you observe flat spots, visible cracks, polyurethane delamination from the hub, or if the wheel no longer rolls freely when manually spun. A grinding or squealing noise typically indicates bearing wear inside the wheel assembly.
Q: Is the SU S635 suitable for wet environments or outdoor storage areas?
A: The SU S635 polyurethane wheel resists moisture better than rubber but should be used in covered areas whenever possible. If the truck operates outdoors regularly, inspect for swelling and cracking every 250 hours. Extended wet exposure may reduce lifespan by 30-40 percent.
