4 in Polyurethane Plate Mount Caster Steel 286 lbs, Pkg Qty 12

Overview

This heavy-duty rigid caster is engineered for demanding industrial applications requiring stable, linear movement and substantial load-bearing capacity. Featuring a robust steel construction and a high-performance polyurethane wheel, this unit delivers exceptional durability while protecting sensitive flooring surfaces. Designed with a standard plate mount configuration, it ensures secure attachment to material handling carts, industrial racks, and heavy machinery. The non-swivel design provides precise directional control, making it ideal for equipment that operates along fixed paths or requires unwavering stability during transport. Each package contains twelve units, facilitating complete outfitting of multi-caster assemblies for large-scale operational needs.

Applications

Industrial manufacturing assembly lines Heavy-duty warehouse transport carts Commercial kitchen equipment and shelving Hospital medical supply trolleys Audio-visual equipment stands Laboratory instrumentation platforms Food processing machinery where floor hygiene is critical The integration of a 5.2-inch polyurethane wheel strikes an optimal balance between load distribution and maneuverability. Unlike softer rubber compounds, this specific polyurethane formulation maintains its shape under maximum load, preventing excessive rolling resistance that can strain operators or motorized drives. The steel frame undergoes rigorous testing to ensure it withstands impact loads common in busy facility environments without cracking or bending. The plate mounting interface allows for versatile installation using standard hardware, accommodating various thicknesses of equipment bases. This caster is particularly effective in environments where noise reduction is a priority, as the polyurethane tread absorbs vibrations and reduces operational decibel levels significantly compared to nylon or phenolic alternatives. Its rigid nature eliminates the sway associated with swivel casters, providing a safer platform for transporting tall or top-heavy loads that require strict alignment. Whether deployed in a cold storage facility or a warm production floor, the materials selected for this unit maintain their mechanical properties across a wide temperature range, ensuring consistent performance year-round.
