4 in Polyurethane Plate Mount Caster 551 lbs Load Black Industrial, Pkg Qty 5

Overview

This heavy-duty industrial caster is engineered for demanding environments where stability and floor protection are paramount. Designed with a fixed-direction configuration, the unit ensures precise linear tracking for equipment that requires consistent movement paths under substantial weight. The black polyurethane wheel construction offers an optimal balance between load-bearing capacity and surface preservation, making it ideal for facilities with sensitive flooring. With a robust plate mount design, this caster provides secure attachment to machinery, carts, and material handling equipment, delivering reliable performance in manufacturing plants, warehouses, and distribution centers.

Applications

Heavy machinery transport and positioning Industrial assembly line carts and dollies Warehouse pallet jacks and platform trucks Medical equipment stands requiring stable movement Food service kitchen racks and utility carts Audio-visual equipment cases for stage and studio use Laboratory benches and testing apparatus requiring precise alignment This caster solution addresses the critical need for equipment mobility without compromising structural integrity or floor conditions. The polyurethane tread compound is specifically formulated to withstand the rigors of daily industrial traffic while minimizing rolling resistance. Unlike softer rubber compounds that may deform under heavy loads or harder plastic wheels that can crack or scar floors, this material maintains its shape and protective qualities over extended service life. The plate mount interface features pre-drilled holes for straightforward installation using standard hardware, reducing downtime during equipment setup or maintenance. The fixed orientation eliminates unwanted swiveling, which is essential for long conveyance paths where deviation could cause safety hazards or operational inefficiencies. Each package contains five identical units, allowing for complete outfitting of four-wheeled platforms with one spare for immediate replacement needs. The overall height of 5.6 inches provides adequate ground clearance for most industrial thresholds while keeping the center of gravity low for enhanced safety during transport. Whether deployed in cold storage facilities or warm production floors, the material properties remain consistent across a wide temperature range, ensuring dependable performance year-round.
