Polyurethane Casters

Individual polyurethane casters in our catalog range from 300 lbs to over 2,000 lbs per caster. Capacity depends on wheel diameter, core material, and mounting hardware. For equipment loads, divide total weight by the number of casters and select wheels rated at least 30% above that figure to account for uneven weight distribution and dynamic loading.

No. Polyurethane is inherently non-marking and will not scuff, stain, or gouge concrete, epoxy-coated, tile, hardwood, or VCT flooring. This makes them one of the most popular choices for facilities where floor appearance and integrity matter, including retail, healthcare, and food service environments.

Polyurethane carries significantly higher loads (often 3-4x more than rubber at the same wheel size), resists abrasion 3-5x longer, and offers lower rolling resistance. Rubber provides slightly better shock absorption and quieter operation at low speeds. Choose polyurethane when load capacity, durability, and chemical resistance are priorities; choose rubber when vibration dampening and ultra-quiet rolling on smooth floors are the primary concern.

Standard polyurethane casters operate from -20 degrees F to 180 degrees F. Within this range, the material maintains its elasticity, load rating, and floor-safe properties. For sustained exposure above 180 degrees F, consider phenolic or metal wheels instead.

Operating reliably from -20 degrees F to 180 degrees F, polyurethane wheels resist oils, greases, solvents, and most industrial chemicals encountered in manufacturing and warehouse environments. Their low rolling resistance means workers exert less push-pull force to move loaded carts and equipment, directly reducing ergonomic strain on your team. Noise output stays well below that of metal or hard plastic wheels, making polyurethane the preferred choice in noise-sensitive environments including hospitals, offices, food processing areas, and retail back-of-house operations.

Whether you are outfitting platform trucks for distribution, rolling tooling across a machine shop floor, or spec'ing casters for heavy shelving in a clean facility, polyurethane delivers measurable advantages.
