Rubber Bellows Mechanical Seal WM301

Rubber Bellows Mechanical Seal WM301 is the most commonly used rubber bellow seal. Due to its compact design, it can be easily mounted. It has a unique rubber bellow secondary seal, which provides a high degree of axial flexibility to compensate for lack of concentric of the shaft misalignment wear due to thrust movement of the shaft. Rubber Bellows Mechanical Seal WM301 can be used regardless of the 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.
