Industrial Casters. Engineered for Spec.
Solid rubber is quieter and more shock absorbent. Solid poly carries more load. For light wash-down where noise matters (hospital, lab carts), solid rubber. For heavy wash-down or higher load, solid poly.
Lower capacity (600 lb vs 1,000 lb at same diameter), softer overall, slightly less wear life. Only choose solid rubber when corrosion at the iron core is a real concern.
Light wash-down carts, hospital wet-area carts, lab equipment in wet zones, food prep support carts (non-direct-contact).
Pair solid rubber wheels with stainless steel rigs for full corrosion immunity. The rig is usually the more expensive failure point, so don't undermine the wheel choice by leaving the rig as carbon steel.
Custom durometer, hub material, plate spec, or non-standard size — engineering team turns RFQs same day.
Standard rubber tolerates dilute sanitizers. For concentrated bleach, peracetic acid, or hot caustics, verify compound — switch to solid poly for aggressive sanitizers.
150°F continuous, brief steam OK. For sustained heat or steam-clean lines, switch to phenolic.
Standard solid rubber is not FDA-rated. Specify FDA-grade compound for direct food contact zones.
Non-marking on most surfaces. Verify on white epoxy or polished concrete with sample.
These calculators apply to any caster application—even if you’re browsing a different category. Use them to estimate load rating per caster, select wheel material, and estimate push/pull force. Expand any tool for full analysis + a share-ready spec line.
