The Economy Stainless Steel Caster Model K3 with Polyurethane Wheel on Polyolefin is built tough for wet, corrosive environments where hygiene and durability are non-negotiable. Crafted from stamped stainless steel, it fights rust and stands up to harsh conditions—think labs, hospitals, or food plants. Its swivel skips the dust cap, adds a drain hole to shed water, and ditches the grease fitting to slash maintenance and costs. It’s reliable mobility for those who need it without breaking the bank.
The Polyurethane Wheel on Polyolefin rolls smooth, stays quiet, and won’t mark floors—perfect for smooth surfaces up to 300 pounds per caster (150 pounds parked). With a polyurethane tread fused to a polyolefin core, plus sealed ball bearings and thread guards, it resists chemicals and corrosion while keeping performance tight. It’s not made for rough terrain or heavy shocks, but it shines where cleanliness and floor care are critical.
This caster fits right into settings like research labs, healthcare facilities, or food service—anyplace demanding sanitation and low noise. It’s a solid pick for light industrial use on smooth floors, delivering no-fuss movement with lasting quality.
