5" Polyurethane Plate Mount Caster Steel 330 lbs, Pkg Qty 20

Overview

This heavy-duty industrial caster is engineered for demanding environments where reliable mobility and floor protection are paramount. Featuring a robust steel frame construction, the unit supports a substantial static load capacity of 330 lbs, making it ideal for transporting heavy machinery, warehouse carts, and large equipment assemblies. The design incorporates a 5-inch polyurethane wheel that delivers an optimal balance of durability and smooth rolling resistance. With an overall installation height of approximately 6.3 inches, this caster provides sufficient ground clearance while maintaining a low center of gravity for enhanced stability. The plate mount configuration ensures secure attachment to various surfaces, eliminating the risk of stem failure common in lighter-duty alternatives.

Key Features

Applications

Manufacturing assembly lines and workstations Warehouse order picking carts and dollies Hospitality linen and food service transport Medical equipment mobility bases Audio-visual rack and case handling Industrial shelving and storage retrieval systems Facility maintenance and janitorial carts The polyurethane tread formulation is specifically selected to withstand continuous operation on concrete, epoxy, and tile surfaces without degrading or leaving residue. Unlike softer rubber compounds that may flatten under heavy weights, this material retains its shape and rolling efficiency over extended periods. The steel housing is fabricated to resist impact damage from debris or accidental collisions, ensuring long-term structural integrity. The mounting plate features four pre-drilled holes aligned to standard industry patterns, facilitating quick retrofitting onto existing equipment or integration into new product designs. This caster solution addresses the critical need for equipment that can endure high-traffic cycles while minimizing operator fatigue through effortless maneuverability. Whether deployed in cold storage facilities or warm production floors, the components maintain performance across a wide temperature range typical of indoor industrial settings.
