ML338 - 5-Inch Rigid Blue Replacement Caster for Welding Carts

Industrial Grade Mobility for Welding Environments

The ML338 5-Inch Rigid Blue Caster is a specialized component designed to restore and enhance the mobility of industrial equipment, specifically welding carts, cylinder racks, and material handling dollies. In a professional fabrication environment, the reliability of mobile equipment is paramount. A compromised caster can lead to safety hazards, tipped gas cylinders, and increased physical strain on operators. This rigid caster is engineered to provide structural stability and predictable directional tracking, making it an ideal choice for the rear or fixed-position wheels on heavy-duty carts.

Robust Construction and Design

Constructed with durability in mind, this caster features a solid 5-inch wheel diameter. The size is optimized to roll over common shop floor imperfections, such as expansion joints, small debris, and welding cables, without getting stuck or jarring the equipment. The rigid (non-swivel) housing is built from stamped steel, offering significant load-bearing capacity suitable for supporting welding power sources, wire feeders, and heavy high-pressure gas cylinders. The blue tread material is selected for its balance of hardness and grip, ensuring it can support heavy static loads without developing flat spots while still providing a smooth ride across concrete surfaces.

Operational Efficiency

Replacing worn or damaged casters is a critical maintenance task that directly impacts workflow efficiency. The ML338 rigid caster ensures that your equipment tracks straight, preventing the "shopping cart" effect where carts drift or become difficult to steer. This is particularly important when transporting shielding gas cylinders, where stability is a safety requirement. The wheel's bearing assembly is designed for low rolling resistance, allowing welders to reposition their setup with minimal effort. Whether you are refurbishing an older welding cart or building a custom shop trolley, this 5-inch rigid caster provides the professional-grade performance required in demanding industrial settings.

Installation and Compatibility

Designed as a versatile replacement part, this caster fits a wide range of standard welding carts and shop equipment. Its mounting plate is compatible with common bolt patterns found in the industry. By maintaining your equipment with high-quality replacement parts like the ML338, you extend the service life of your carts and ensure a safer, more productive work environment.
