Conical spring washers are used in many different industries. At Freeway Corporation, we produce high-quality conical spring washers designed to meet our client’s exact specifications for size, thickness and materials. Our design and manufacturing expertise can be leveraged to create your very own custom conical washers.
A conical washer, also referred to as a conical spring washer or Belleville washer, is used to absorb vibration and maintain preload in bolted joints. Conical washers provide a spring force that prevents bolts from loosening due to vibration or thermal expansion. Using multiple conical washers can allow for deflection of the bolt assembly which is useful in dynamic load environments.
Place the conical washer with the concave side (the smaller diameter) facing the surface of the material. The wider, convex side should face the fastener head or nut. Ensure the fastener (bolt, screw, or nut) is centered in the washer. Tighten the fastener to the recommended torque specifications. As you tighten, the conical washer flattens slightly, creating additional resistance against loosening due to vibration or dynamic loads. Proper installation helps conical washers prevent loosening and distribute stress across the assembly, improving the longevity and reliability of bolted joints.
There is no difference between a conical washer and a Belleville washer. The inventor Julien Belleville patented a spring design that was based on disc springs, and his name has since become synonymous with the conical spring washer. Other names for conical washers include coned-disc springs, cupped spring washers, conical spring washers and Belleville springs.
