Belleville spring washer DIN, GB
Shanghai Jingyang
Spring washers are disks of metal that are formed in an irregular shape so that when the washer is loaded, it act like a spring, and provides a preload between two surfaces. Spring washers are typically used in applications where assemblies need a part to take up play, eliminate rattle, maintain assembly tension, compensate for expansion or contraction in materials after assembly, or to absorb intermittent shock loads and provide a controlled reaction under dynamic loads.
