A washer is a plate with a hole that lets a fastener to pass through it. The most common shape is a flat disk with a concentric hole. Washers are frequently used to distribute the clamping force from threaded fasteners over a larger area. This prevents bolt heads and nuts from indenting the surfaces of the fastened parts, which could loosen the fastener.
Washers can serve as a spacer and are available in serrated or tabbed to prevent unscrewing. Sprung washers offer axial flexibility and are used to prevent fastening or loosening because of vibration, or to indicate correct pre-load. Several different types of washers are available to suit different applications.
For example, Belleville springs are a sprung washer in the shape of a conical shell, which can be loaded along its axis statically or dynamically. They are also called Belleville or conical spring washers. Belleville washers are typically used in conditions of high current loading or cycling. They are used to absorb vibration and can maintain preload in bolted joints, indicating correct preload based on the gap between adjacent washers. They can also help with &#;bolt creep&#; or stress relaxation between a bolt and washer.
However, one feature Belleville washers are unable to provide is significant locking capacity in bolted applications because of a lack of serrations. Although this can be beneficial, depending on the application, because serrations can also damage the clamping surface.
Although they resemble a washer, Belleville washers are often used as a spring to actuate mechanisms and provide suspension. They can be stacked together in different ways to create longer springs with highly configurable spring rates. They have a number of specific advantages for such applications, including:
&#; Configurability through stacking
&#; High force within a small or confined space
&#; Concentric force distribution
Stacks that use a combination of alternating and same direction Belleville springs can achieve particular spring characteristics. For example, when two or more Belleville springs are stacked together, this changes the spring rate. If multiple springs are stacked in the same direction, this is equivalent to arranging springs in parallel. Although the total range of motion remains the same for one spring, the force generated is multiplied by the number of springs.
When Belleville springs are arranged in this way there is also significant friction between the mating surfaces. This creates a damping effect that can reduce vibration.
Belleville washer s help keep bolted connections tight. They preserve bolt integrity, particularly in areas that must bear a heavy load. They allow for high load capacity, relative to deflection and available space within the application. American Belleville can provide Belleville washers of limitless dimensional configurations and load/deflection ratings. In some instances, the addition of a flat washer increases the effectiveness of a Belleville disc spring by helping to spread the load.

A Belleville lock washer is a type of spring in the shape of a washer. They are sometimes known as a conical spring washer, Belleville spring, disc spring, coned-disc spring, or cupped spring washer. Belleville Washers allow for high load capacity and protect against vibration, thermal expansion, relaxation, and bolt creep issues. Learn how to select the right Belleville washers and why to work with American Belleville for your Belleville washer needs.
Belleville washers apply pressure to bolted connections once you clamp down on them with the proper amount of force. The advantage of this washer is that it applies clamping pressure along a continuous arc pattern, instead of concentrating it at one point, to prevent stress on bolts and washers. Uneven bolt stress can leave some connections loose, while others are overtightened and crush the gasket. This can cause severe service leaks, especially in high-temperature services when the heavily loaded bolts relax. The same goes for excessive vibration, which can loosen flange bolts and ultimately cause flange leakage.
Most often, you&#;ll find Belleville washers in applications where you have conditions of high current loading or cycling. These washers accommodate for thermal cycling, but they can&#;t eliminate all the problems resulting from poor workmanship. You must prepare the joint properly (as with any connection), but the key is selecting the proper design and size of Belleville washer for the fasteners and conditions of your application.
Consider three parameters to select the right Belleville washer: torque, diameter, and finish. Visit our products pages to find this information in each product&#;s specifications.
This is the force you need to place on the bolt to flatten the washer for proper clamping. To make a tight connection, you must tighten the connection to the point where its threads just start to deform. Bolts of various hardness, diameter, and material configurations require varying amounts of torque to reach that tightness; this is the same with Belleville washers.
Make the torque for your Belleville washers match that of your bolts to make sure they&#;re working together. If you exceed a locking washer&#;s torque, you can destroy the locking washer. And if you under torque, you won&#;t make use of the washer&#;s abilities to provide a reliable connection.
A Belleville washer generates a clamping force along the tip of its cup perimeter. A correct diameter is important because if it&#;s too big and the cup overhangs the connection, you&#;ll have much less clamping force than you need. Search our Belleville Washer product listing to find the diameter you need. If you can&#;t find a perfect fit on our website, simply contact us and we&#;ll find the solution you need.
You can usually select a standard finish for a Belleville washer. However, if there are any process fumes or solvents present, the wrong finish can result in a connection that falls apart. For example, electroplated Belleville washers become brittle in the presence of hydrogen. If you subject a hydrogen-exposed electroplated washer to impact or severe vibration, that washer will break into pieces.
