ensures that this caster performs exceptionally well on both smooth and slightly uneven surfaces. Unlike harder rubber or metal alternatives, the polyurethane compound offers significant noise reduction, which is critical for environments such as hospitals, libraries, or quiet office corridors. The M12 threaded stem, measuring approximately 1.18 inches in length, is designed to screw directly into standard mounting plates or equipment frames, eliminating the need for complex installation tools or additional hardware adapters. This direct-mount approach maximizes structural integrity and minimizes the risk of stem failure under dynamic loading conditions. Each package contains twelve units, providing a complete set for equipping four-wheeled carts with spares available for future maintenance needs. The specified load rating of over 154 lbs per caster allows for a total system capacity exceeding 600 lbs when deployed in a standard four-caster configuration, accommodating substantial weight requirements without compromising performance or longevity.
