Benefits

• High load handling makes these casters suitable for manufacturing carts, maintenance trolleys, hospital supply carts, and industrial workstations—supporting heavier loads without sacrificing mobility.
• Polyurethane wheels provide a balance of durability and floor-friendliness, reducing tire wear and minimizing floor marking on concrete, tile, and sealed surfaces.
• All-polymer housing variants avoid metal corrosion and simplify maintenance in humid or chemical environments.
• The ability to choose from multiple materials lets you tailor performance to your environment: hard rubber for smooth, rigid surfaces; soft rubber for better grip on uneven floors; polyurethane for high-traffic areas with heavier loads.
• Replacement flexibility: casters are sold individually, enabling simple, targeted maintenance—swap out a single caster to restore cart performance without replacing the entire rig.
• Operational versatility: compatible with a range of carts in the Metro Super Adjustable Casters family, helping maintain consistency across equipment fleets.
