Black torsional rubber bellow comes in a large variety of sizes, shapes, construction and elastomer rubbers to suit diverse application requirements of vehicles. Due to different annular convolutions, bellows are easily extensible and compressible. Rubber bellows are appreciated for providing excellent cushioning effect to protect, cover and enhance the service life of various machine parts. Depending upon the end use requirements, rubber bellows are manufactured using various synthetic rubber, such as NBR+PVC, EPDM, HNBR etc.
When designing rubber bellow, below factors need to be taken into account:
1. Right material selection according to specific working invironment, such as oil, lubricants and grease resistance, ozone and UV resistance, withstand high termperature, etc.
2. Shape of the bellow
3. Inner & Outer diameter of bellow
4. The free or the unloaded length of the bellow along the convolutions
5. The spring rate or the spring force that the bellow applies
