DIN2093 Spring Bowl Washer

Specifications for DIN2093 50CrVA Spring Bowl Washer

DIN 2093 spring washers are important fastening components defined by the German DIN standard.

Structure and Shape
● Special Design: They usually have a conical or toothed structure. The conical design allows for better distribution of force and elastic deformation. The toothed type has teeth on the surface, which can increase friction and enhance the anti-loosening effect.
● Accurate Dimensions: The inner diameter, outer diameter, thickness and other dimensions of DIN 2093 spring washers are strictly regulated by the standard to ensure a precise fit with different fasteners.

Material and Properties
● High-Quality Materials: Commonly made of high-carbon steel or alloy steel, which possess high strength and excellent elasticity. Some may also be made of stainless steel for applications requiring corrosion resistance.
● Good Elasticity and Fatigue Resistance: They can withstand repeated loading and unloading without losing their elastic properties easily, ensuring long-term reliable anti-loosening performance.
● Effective Anti-loosening: The main function is to prevent bolts and nuts from loosening. When the connected parts are subjected to vibration or dynamic loads, the spring washer deforms elastically and exerts a force on the bolt and nut, keeping them in a tight state.
● Load Distribution: It can also help distribute the load evenly across the contact surface between the bolt and the connected part, reducing stress concentration.

Applications
● Aerospace Industry: Used in aircraft engines, airframe structures and other key components to ensure the reliability of connections under high vibration and high stress conditions.
● Heavy Machinery: Employed in large industrial machinery, such as in the connection of gearboxes, engines and other components in construction machinery and mining equipment.
● Railway Industry: Applied in the assembly.
