Rubber bellows mainly make use of the flexibility of corrugation to achieve rubber’s unique performance, such as high elasticity, high gas tightness, medium resistance, weather resistance and radiation resistance. Rubber bellows is preformed by pure rubber, then by high temperature mould pressing or use polyester cord fabric with high strength and strong hot-cold stability to oblique crossing and recombine, and cross linked by high pressure and high temperature mould pressing. It has high inner density, high pressure bearing capacity and excellent elastic deformation effect. Distinguish from metal bellows, the biggest feature of rubber bellows is its good shock absorption and noise reduction property. According to different using condition and different property requirements, rubber bellows are differ in thousands of ways, commonly seen specification includes size, material, hardness, color, temperature, pressure, working environment, etc. Rubber bellows owns advantages of good compressibility and rebound resilience, small permanent deformation, no soften and decompose under high temperature, no harden and embrittlement under low temperature, good corrosion resistance property, low friction coefficient, good abrasive resistance and ageing resistance, durable in use. And rubber bellows is widely used in aviation, petroleum, chemical engineering, metallurgy, electric power, paper making, medicine, food, wood material, tobacco and transportation industries for its low outer diameter tolerance, anti to oil and heat, light and convenient, etc. Since rubber bellows is able to flex but no influence on product property, plus advantage of noiseless, it has a wider application in machinery auto parts industry.
