Belleville washers, also known as conical spring washers or coned-disc springs, are conical shaped metal disks made to handle high loads with limited deflection. Given the curve of its shape and design to meet any locking requirements, Belleville washers can be used in various applications. Belleville washers can also be stacked together in parallel, series, and parallel/series configurations to increase deflection and load tolerances.
● Available in alloy steel, spring steel, and stainless steel
● Also available in zinc, phosphate, or plain finishes
● Maintain high joint tension despite thermal expansion
● Belleville washers are often used to reduce vibration and relaxation
The purpose of a Belleville washer is to absorb loads by acting as a spring. When a load is applied a Belleville washer, the washer compresses. At the same time, the Belleville washer exerts an equal amount of force against the object. This means Belleville washers can handle larger, heavier loads that aren’t possible with conventional washers.
Depending on the application, multiple Belleville washers can be used to create greater resistance against heavy loads. Rather than using a single Belleville washer, you can use two or three Belleville washers. The stack of Belleville washers creates multiple springs, each of which acts against the object.
In addition to handling heavy loads, Belleville washers are able to absorb vibrations. Many vehicles, for example, use Belleville washers for this reason. Vibrations can often knock conventional washers loose, but this isn’t a problem with Belleville washers because of their canonical shape. Even under constant vibrations, a Belleville washer shouldn’t come loose.
Belleville washers are suitable for all applications. But their canonical shape and spring-like characteristics make them ideal for handling heavy loads and absorbing vibrations.
