corrugated tube coupling consists of two hubs and a thin-walled metal tube, which are connected together by either welding or bonding. Stainless steel and nickel are the most commonly used metal pipe materials, although many other materials are available. Nickel tubes are made using electrodeposition. This method first involves machining a solid mandrel into a corrugated shape, electroplating nickel on the mandrel, and then chemically dissolving the mandrel to create a nickel corrugated tube. This method can control the accuracy of the bellows wall thickness and achieve a thinner wall thickness than bellows made by other methods. This thin-walled bellows makes the coupling highly sensitive and responsive, making it ideal for use in extremely small and precision instrument applications. The elastic element of the bellows coupling is a precision metal bellows, which is divided into two types: flexible series and rigid series. The flexible series has greater elasticity and is often used in micro-scale applications such as encoders and sensors. The rigid series is mainly used in servo drives. Motors, CNC machine tools (machining centers) and other occasions.
The main producing areas of bellows couplings are Europe, the United States, Japan, Taiwan, and mainland China.
