2064011 - ESAB Stainless Steel Belleville Spring Washer .50 x .26 x .04

Precision Engineered Tension Components

The ESAB 2064011 is a high-performance Belleville washer designed for critical industrial applications where space is limited but high load capacity is required. Unlike standard flat washers, a Belleville washer (also known as a coned-disc spring, conical spring washer, or disc spring) has a frusto-conical shape which gives the washer a spring characteristic. This specific component is manufactured from premium stainless steel, offering excellent resistance to corrosion and oxidation, which is particularly important in welding environments where equipment may be exposed to humidity, fumes, and varying temperatures.

With an outer diameter of 0.50 inches, an inner diameter of 0.26 inches, and a thickness of 0.04 inches, this washer is engineered to provide a specific spring rate and deflection. In mechanical assemblies, such as wire feed systems or torch tensioners, these washers are often used to maintain a preload on a bolted joint or bearing. They effectively compensate for differential thermal expansion, creep, or wear of the clamped parts, ensuring that the assembly remains tight and functional over long periods of operation. The stainless steel construction ensures that the spring properties are maintained even in harsh industrial settings.

For maintenance professionals and industrial repair technicians, using genuine OEM parts like the ESAB 2064011 is crucial for maintaining the original performance specifications of the equipment. Generic washers may not possess the correct metallurgical properties or dimensional tolerances, leading to premature failure or improper tensioning. This washer is designed to operate under high loads with small deflections, making it an essential component for maintaining the precision and reliability of ESAB welding machinery. Whether used singly or in a stack (series or parallel) to modify the spring constant and deflection, this component is integral to the mechanical integrity of the system it serves.

When replacing these components, it is vital to ensure the correct orientation (cup up or cup down) as specified in the equipment's service manual, as this directly affects the load-deflection characteristics of the assembly. This part is supplied as a single unit, allowing for precise replacement of worn or fatigued springs during routine maintenance or overhaul procedures.
