Polyolefin (industrial plastic) wheel casters are a cost-effective choice for medium-duty carts and equipment where washdown, chemicals, or corrosion exposure is common. Lightweight, impact-resistant, and easy rolling on smooth floors.
Typical use: carts, racks, bakery/food service equipment, labs, medical carts, and general plant/warehouse handling.
Capacity varies by wheel size, bearing, and top plate/rig selection—use the lower-rated component for your true system capacity.
If you’re rolling over debris, cracked concrete, expansion joints, or thresholds all day, consider a softer tread (TPR or polyurethane) to reduce vibration and improve ride quality. If floor protection and noise reduction are critical, polyolefin may be too hard depending on load and surface.
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.
