4 in Polyurethane Plate Mount Caster 660 lbs Heavy Duty, Pkg Qty 10

Overview

This heavy-duty plate mount caster is engineered for demanding industrial applications where stability, floor protection, and high load capacity are critical. Designed to support substantial weight in medium to heavy equipment setups, the unit features a robust polyurethane wheel that balances durability with smooth operation. The integrated swivel mechanism allows for 360-degree maneuverability, while the built-in braking system ensures secure positioning during loading, unloading, or stationary operations. Ideal for warehouses, manufacturing facilities, and assembly lines, this caster delivers reliable performance under continuous use without compromising floor surfaces.

Applications

Industrial material handling carts and dollies Heavy machinery relocation platforms Assembly line workstations and benches Warehouse order picking trucks Food processing equipment requiring non-marking wheels Hospitality and institutional bulk transport carts Automotive service equipment and tool cribs The polyurethane construction offers an optimal balance between the hardness required for load-bearing and the elasticity needed to absorb shock and reduce vibration. This composition significantly extends the lifespan of both the caster and the flooring it traverses. The mounting plate is pre-drilled with standard hole patterns to facilitate quick installation onto existing frames or new fabrication projects. Each unit undergoes rigorous quality checks to ensure the swivel raceway operates smoothly under full load conditions. The braking mechanism engages directly with the swivel head, preventing rotation effectively even on slight inclines. Sold in packages of ten, these casters provide a cost-effective solution for outfitting entire fleets of industrial equipment with uniform, high-performance mobility components.
