General purpose rubber bellow seal is most commonly used as rubber bellow seal. It has a unique rubber bellow secondary seal, which provides a high degree of axial flexibility to compensate for lack of concentricity of the shaft & misalignment & wear due to thrust movement of the shaft. Due to its compact design it can be easily mounted. The seal can be use regardless of direction of rotation, since the driving torque is not transmitted through the coil spring. The required driving torque is enhanced through the unique rubber bellow, which fits on the shaft. There are no bonded joints and all the face materials are interchangeable without having to modify any dimensions.
