Rubber Bellow are available in a range of sizes and designs allowing for relatively high levels of deflections for shock absorption. The rubber bellow can be supplied with metal inserts to assist with installation. In most cases their design is such that the centre of the rubber spring is hollow and profiled to allow for high levels of deflection without over stressing the rubber.
By altering the rubber hardness and the inner profile of the rubber spring, the stiffness characterisitics can be amended to suit the application accordingly.
