183387 - Miller 183387 Cone Washer .380 ID x .860 OD Steel Plated

Genuine Miller 183387 Cone Washer for Industrial Welding Equipment

Maintain the integrity and performance of your Miller welding equipment with the Miller 183387 Cone Washer. This specialized hardware component is not just a standard flat washer; it is a precision-engineered conical spring washer, often referred to as a Belleville washer. Designed to handle significant mechanical stress, this washer is rated for a 4,000 lb load, making it an essential part for assemblies requiring high tension retention and resistance to vibration.

The washer features precise dimensions of 0.380-inch Inner Diameter (ID), 0.860-inch Outer Diameter (OD), and a thickness of 0.109 inches. Manufactured from high-quality steel, it offers the structural rigidity necessary for industrial environments. To further enhance its longevity, the steel is plated, providing a robust layer of protection against rust and corrosion—a critical feature for equipment used in variable shop conditions.

Why Use OEM Cone Washers?

In welding machines, particularly in wire feed systems and spool brake assemblies, maintaining the correct preload on bearings and bolted joints is vital. A cone washer acts like a spring, absorbing shock and compensating for thermal expansion and contraction. Using a generic flat washer in place of the Miller 183387 can lead to loose components, inconsistent wire feeding, or premature wear of mating parts. By choosing this genuine Miller replacement, you ensure that your machine operates exactly as the engineers intended.

Whether you are performing routine maintenance or a critical repair, the Miller 183387 ensures a perfect fit and reliable function. Its heavy-duty load rating makes it suitable for high-stress points within the machine's internal architecture.
