4 in Polyurethane Stem Caster 616 lbs Plate Mount for Heavy Duty, Pkg Qty 2

Overview

This heavy-duty caster assembly is engineered for rigorous industrial environments where reliable mobility and substantial load-bearing capacity are critical. Designed to support static loads up to 616 lbs, the unit features a robust construction that ensures stability for large machinery, warehouse carts, and manufacturing equipment. The wheel utilizes advanced super-polyurethane material, offering an optimal balance between durability and floor protection. Unlike traditional rubber or hard plastic wheels, this formulation minimizes rolling resistance while preventing damage to sensitive flooring surfaces such as epoxy, concrete, or tile. The design prioritizes long-term performance in demanding settings, resisting degradation from common industrial chemicals, oils, and abrasive debris.

Applications

Heavy manufacturing assembly lines Warehouse logistics and material handling carts Industrial food processing equipment Hospital and medical device transport Automotive repair shop machinery Commercial cleaning equipment platforms Textile and printing industry machinery The structural integrity of this caster is defined by its precise dimensions and material selection. With a wheel diameter of 3.9 inches and a total installation height of 5.7 inches, it fits seamlessly into standard heavy-duty equipment frames without requiring significant modification. The plate mount configuration, measuring 5.7 inches by 4.5 inches, provides a wide footprint for bolt patterns, distributing weight evenly and reducing stress on the mounting surface. This makes it particularly suitable for applications involving frequent starts, stops, and directional changes. The super-polyurethane construction not only extends the service life of the wheel under continuous use but also significantly dampens noise and vibration, contributing to a safer and more comfortable workplace environment. Whether moving loads across rough concrete floors or smooth facility tiles, this caster delivers consistent performance and reliability.
