Belleville disc springs are critical fasteners that are used to apply preload pressure or tension to a wide range of mechanical components such as bolts, screws, shafts, and flanges, among others. These versatile Belleville disc spring washers have an inside diameter (ID) of 1.122 inches, an outside diameter (OD) of 2.205 inches, and a height of 0.1339 inch when compressed. As tension is applied, the Belleville spring washer conforms to its load, enabling it to resist subsequent loads until the compression limit is reached; hence they are critical components in holding assemblies together in various applications, such as machinery, vehicles, and heavy equipment. Belleville disc springs are reusable, meaning they can be compressed again and again without losing their effectiveness or shape, which not only reduces maintenance costs but also enhances performance, reliability and durability of the application in general.
