DIN137B Stainless steel Wave spring washers

spring washer 12,5x5,2x0,5 DIN EN 16982 A2, As a kind of high-performance seal, saddle elastic washer has a wide range of application prospects in the market. It can be used in hydraulic systems, pneumatic equipment, sealing valves, and many other fields. For example, in the hydraulic system, saddle-shaped elastic washers can effectively seal the gap between the piston and cylinder of the hydraulic cylinder, to prevent hydraulic oil leakage and improve the efficiency of the system. In sealing valves, saddle-shaped elastic washers can ensure the sealing performance of the valve to avoid leakage of media.    

The saddle washer's anti-loosening principle is to use its special structural shape and material properties, the formation of elastic deformation, and friction resistance to loosening on the fasteners. Specifically, its anti-loosening mechanism has the following aspects.
1. Elastic deformation: When the fastener is subjected to external force in the course of use, the saddle washer will undergo elastic deformation, and the spring inside the washer will be pressed to produce elastic retraction force, which makes the fastener tight and prevents loosening.
2. Friction: The saddle washer face hole is rough, and the fastener surface forms a good friction fit, so the friction increases so that the fastener is more difficult to loosen.
3. Bayonet and locking: Saddle washers are designed with a bayonet at the mounting position on the fastener, making it less likely to be loosened by fastening, and not only are they locked after being fastened and secured, but also the compression fixing force is strengthened.
