StS Metal Bellow / Magnetic Couplings

Metal Bellow Couplings
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 against being as subcontractor to a leading manufacturer of couplings, for 15 years. During this period, a vast experience in development and production was gained. Considering the growth potential, experienced personnel flocked to StS, enriching the experience quotient of this Company.

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.

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.
