Introduction Welcome to the Dunlop Pneuride range of air bellows. These bellows are used in a wide variety of applications: Primary Application: Suspension media in all sorts of vehicles (buses, trucks, trailers, semi trailers, demountable systems, container handling systems, coaches, ambulances, etc). Secondary Application: Dunlop Pneuride Bellows, whilst originally designed for vehicle applications, have a range of unique characteristics which make them extremely attractive for industrial applications such as pneumatic/hydraulic actuation, isolation mounts, height and level control devices. Furthermore, although not specifically designed as a noise insulator, Pneuride Bellows do reduce noise transmission. Bellows are produced in a range of sizes from 4½ x 1 up to 21½ x 2. Lobes Pneuride Bellows are manufactured using a mixture of elastomers and textile reinforcement which produces a high quality, high performance product. They are frictionless, economical and virtually maintenance free and come packaged in one of three forms: 1, 2, or 3 lobes...

Isolation Dunlop Pneuride Bellows are an excellent solution to vibration isolation problems. The table opposite shows the natural frequency of the bellows at static height when pressurised at 4 bar (0.4 Mpa). The table below al lows the calculation of the percentage isolation at given forcing frequencies and natural air spring frequencies.
