Disc Springs for High Load Applications 

Disc springs, also known as disc washers or belleville washers, are ideal for high load applications especially where space is limited. The conical disc spring is made from a convex disc where the outer edge operates in opposition to the center of the disc. This creates a high spring force within a short area of movement. The disc spring configuration enables these springs to support higher loads with relatively small deflection and less solid height than a standard helical designed springs. Disc springs are versatile and are used in many manufacturing and plant applications. Some common uses for disc springs include:

• Vibration control
• Thermal expansion
• Relaxation and Bolt Creep Problems
• Energy storage
• Slip and overload clutches
• Valves
• Spring actuated brakes

Plus other applications that require disk springs.
