109318 - Miller Swivel Caster 2.5-Inch 5/16-18 Thread

Keep Your Miller Welder Rolling Smoothly

Don't let a broken or stuck wheel slow down your fabrication projects. The Miller 109318 Swivel Caster is the direct replacement you need to get your welding cart or wire feeder moving freely again. In a busy welding shop, mobility is everything. Whether you are moving between bays or just repositioning for a better angle on a workpiece, fighting with a cart that has a flat spot or a seized bearing is a frustration you don't need. This genuine Miller part is built to handle the heavy load of welding power sources and gas cylinders with ease.

Designed for the Shop Floor

Welding environments are tough on equipment. Debris, sparks, and heavy loads take their toll on running gear. This caster features a 2.5-inch wheel made from Cushionex, a material chosen for its ability to roll over imperfections in the floor while providing a cushioned ride. This is important not just for ease of movement, but also for protecting the internal components of your welder from harsh vibrations during transport. The swivel design allows for 360-degree rotation, making it easy to turn your equipment on a dime in crowded workspaces.

Easy DIY Replacement

Replacing a caster is one of the easiest maintenance tasks you can perform to upgrade your daily welding experience. The Miller 109318 comes with a 5/16-18 threaded stem (listed as .312-18) that simply screws into the base of your compatible Miller equipment. The stem is 0.75 inches long, ensuring plenty of thread engagement for a secure hold. No complex tools are required—just a wrench to tighten it down.

Why Choose Genuine Miller Parts?

When you buy the Miller 109318, you aren't guessing at weight ratings or thread pitches at the hardware store. You are getting the exact part engineered for your machine. Generic wheels often fail under the specific weight distribution of welding carts or have stems that are slightly the wrong length. Stick with the brand you trust and ensure your welder stays mobile and safe. Check your owner's manual or parts list to confirm this part number matches your specific model of running gear.
