About Disc Spring
It has a frusta-conical shape which gives the washer a spring characteristic.
Through a unique combination of high force in a small space, Belleville washer can be used as single disc or arranged in stacks. A spring stack can consist of either single spring or parallel spring sets.
Manufactured to DIN 2093 standard and non-standard. Design programmed to assist customers for their specified applications. The method of heat treatment is particularly effective for springs, as it gives the maximum toughness and therefore considerable durability.
