Butterfly Washer

Disc washers, also known as bowl washers, conical washers, etc., have conical design, are hardened with good elasticity function, used in the machinery and equipment industry with moving loads. Disc spring washers belong to the category of safety fasteners, so the requirements for professional manufacturing capacity are high, need to do a static negative load-bearing pressure test!
Disc washers have a wide range of uses, a kind of high-tension anti-loosening washers used with matching bolts, suitable for high-strength hard connection parts, The manufacturing and application of disc washers are affected by many conditions, need to be scientifically understood, otherwise, it is difficult to achieve the safety function!    

Advantages and features: high axial load, high fatigue life, high compensation of load drop (caused by temperature difference), effective reduction of the negative impact of dynamic load, anti-loosening locking, high elasticity, uniform load concentration, and high degree of safety.
Manufacturing implementation standards: in line with NFE25510 and DIN6796-HS standards. Specifications: M5-M20 models, can also provide customized service main materials are S60C, 60Si2mn,51crav4, and special alloy materials, salt bath hardening, surface treatment of phosphating black, mechanical zinc, Dacromet coating, and so on! Chemical plating is not available! In most cases, the standard type disc spring washers do not fully meet the user requirements, through the calculation and appropriate adjustment to obtain the ideal customized features!
Application: This product is now widely used in electrical appliances, elevators, towers, machinery and equipment, and medical machinery products supporting disc-type improved fasteners, The quality is in line with the German standard DIN6796 disc spring standard.
