POLY LOAD WHEEL
Frequently Asked Questions
Q: What is the load rating and material composition of SU S341 poly load wheels?
A: SU S341 is a polyurethane load wheel rated for 2200 lbs per wheel. The poly material is more durable than rubber in cold storage and outdoor environments. SU S341 has a 1.5 inch hub bore matching SU S338 steel wheels, so they can be mixed on the same truck.
Q: Can I replace SU S338 steel wheels with SU S341 poly wheels?
A: Yes. Both use 1.5 inch hub bores and 65 ft-lbs bolt torque. The bolt pattern and axle spacing are identical. SU S341 poly wheels are quieter and provide better grip on wet or icy surfaces compared to rubber SU S338 wheels.
Q: What is the temperature range for SU S341 polyurethane wheels?
A: SU S341 poly wheels perform reliably from negative 20 degrees Fahrenheit to positive 140 degrees Fahrenheit. Below negative 20 degrees the poly material becomes brittle and may crack. Above 140 degrees the material will soften and deform. For extreme temperatures, confirm application suitability with your parts supplier.
Q: How do I diagnose failure symptoms in SU S341 poly wheels?
A: Visible wear signs include shiny or polished areas on the tread (friction damage), chunks missing from the tire edges, and visible cracks radiating from the center hub. If the wheel feels spongy when pressed by hand or does not roll straight, the polyurethane has absorbed moisture and internal delamination has begun. Replace immediately.
Q: How long do SU S341 poly wheels last compared to rubber wheels?
A: In standard indoor warehouse conditions, SU S341 lasts 4-6 years versus 3-5 years for rubber wheels. In freezer or outdoor environments where rubber becomes hard and brittle, SU S341 outlasts rubber by 2-3 additional years. Maintenance and greasing intervals are the same for both materials.
Q: Are SU S341 poly wheels louder or quieter than rubber wheels?
A: SU S341 poly wheels are approximately 3-5 decibels quieter than rubber wheels during operation. This makes them ideal for noise-sensitive environments like libraries or hospitals. The reduced noise does not indicate reduced load capacity or lifespan.
