Rubber Bellows, Alternate to Metal Coil Springs

Vishwaraj Rubber Industries offers Rubber Bellows as alternative to Metal Coil Spring. These are manufactured with indigenous technology and provide complete solution for the vibration isolation and support of machines. The rubber bellows air spring gives consistently good isolation even under changing loads. It isolates both low-frequency vibrations and structure borne noise. A true substitute for metal coil spring, this is noise free, requires no maintenance and durable. Rubber bellows are ideal for many applications in mechanical engineering and in the construction for machinery and equipments. Air actuators, like cross ply tyres, are made of a fabric-reinforced rubber bellow completed with connecting parts to form an airtight system. By use of high grade materials and modern manufacturing methods, the safety requirements of the industry are met. These rubber bellows are available in single, double and triple convolution from 3.1/2”, 6”, 8”, 10” and 12” diameter and with different mounting style as per the application. Advantages: in both above cases, rubber bellows are cost saving in a various ways like easy design calculation, easy installation, low space requirement, versatile, longer service life, purchase price, ability to absorb lateral forces, constant isolation efficiency, accurate height control, wide size range, effective noise reduction, no maintenance and simplified construction, friction free for immediate response. Applications: automotive alignment equipment, paper and textile machinery, material handling, expansion chambers, test bed shakers, generator sets, industrial machinery, vibrating screens, seat springs, vibrating test equipment, shock absorbers, inertial mass mounting, and vibrating conveyors and feeders. Technical data: medium – compressed air, non lubricated; operation – single acting; operating pressure – 100 PSI maximum; operating temperature – -20 to +70°C; nominal diameter – 3-1/2”, 6”, 8”, 10” and 12”; stroke lengths – from 20 to 300 mm maximum depending on diameters and numbers of convolutions; materials of construction – end plates – zinc chromate steel, rubber parts – fabric reinforced NR – SBR – BR compound.
