Product Specification :
PS – 143 Elastomer Bellow Seal has been designed for general sealing purpose which includes easy installation of the seal.

Elastomer Bellow Seal 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.

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 through the interference fit between the collar, rubber bellow & the shaft.
