Shanghai Hegong Disc Spring Manufacture Co.,Ltd

Belleville Washers DIN6796 also be known as "Conical Spring Washers", "Heavy Duty Bolting Washers", "Heavy Duty Safety Washers", "Spring Washers", "Belleville Springs", etc. Belleville Washers are widely used in industries such as national defense, metallurgy, engineering, electric power, machine tools, etc.
Heavy Duty Safety Washers DIN6796 is a specialty version of Belleville Spring Washer used to improve security of bolt connection, manufactured as per DIN6796 standard. It is applicable to the static bolting applications in the medium and high strength range.
Belleville Washers supplier helps to balance the stress relaxation in bolt / nut assembly, and has the following functions for loss of preload force, thermal expansion and contraction, and compression of seals caused by wear, deformation and creep of wearing parts:
a. Have enough elasticity to improve the whole elasticity of the connecting pair.
b. The inherent elastic force can compensate for the loss of preload force, meet the clamping force requirements, and ensure the reliability of the connection pair.
Note: Relative movement will occur between the bolt and nut , if the lateral force overcomes the friction between the clamped elements. Generally, the Belleville washers cannot prevent the connection pair from loosening due to the lateral movement. Therefore, it is necessary to detect whether the Belleville washers maintains the clamping force.
