Metal Bellows Couplings


We are Manufacturer, Supplier, Exporter of Metal Bellows Couplings and Our setup is situated in Pune, Maharashtra, India.

The metal bellow coupling is designed to be used in various torque transmission applications. The metal bellow perfectly compensates for axial, radial, and angular misalignments. The designed geometric shape of the steel bellow allows high torsional stiffness and a low mass moment of inertia. The Bellow Coupling is manufactured in five sizes for maximum torques up to 400 Nm. The coupling steel bellows and clamping rings are the same for all the designs within a construction size. They are adapted via reducing bushings to the required shaft diameter. These bushings can be of Stainless steel or of Aluminium.

We also develope custom bellows couplings based on customer requirements.
