StS Metal Bellow / Servo Insert / Magnetic Couplings

Metal Bellow Coupling

Steel Metal Bellow Couplings offer backlash free transmission with added advantages of high flexibility and torsional stiffness.

StS launched its own brand of couplings in January 2009 after working as the main sub-contractor to a leading Brand of couplings, for 15 years. During this period, StS gained a vast experience in development and production methods, which offers improved performance. Considering the growth potential, experienced personnel flocked to StS, enriching the experience quotient of this Company.

Product Profile

These couplings consist of a stainless steel metal bellow joined together to Al or Steel hubs provide a complete backlash free transmission between 2 shafts, with various other advantages. Designed to transmit a torque range of 0.4 Nm to 5,000 Nm with bore diameters from 3mm to 85 mm in divergent models, including plain bore/keyway, side and top clamping, internal and external conical hubs. Apart from this large standard range, Sts specializes in developing new models to the needs of clients.

Our strengths

Although this brand – StS – has been around only for the past few years - it has carved a niche for itself in the midst of so many experienced manufacturers. Quick delivery, competitive prices and a deep desire to excel have made StS a by word, for success.

Quick Clamping System

Trantorque Keyless Bushings provide a zero-backlash frictional connection that can accommodate high-torque, thrust, bending, and/or radial loads. Designed with an external counter torque nut for easier installation, by allowing the system to be held from rotating during installation. The Trantorque Series of Keyless Bushing has exceptional concentricity while maintaining the ability to accommodate bending loads. There is limited axial movement during installation. All Trantorque units use a single hex nut for speed and simplicity of installation.
