CENTA X-SEC AT A GL ANCE CENTA offers a modular CENTAX-SEC coupling system, which allows a constructive maximum of flexibility. Features High flexiblity in design High flexibility in all directions High flexibility in torsional elasticity The components of the series are perfectly matched: multiple combinations allow for various features, and easy control of any torsional situation. Ensuring reliable compensation of axial misalignments three optional components are available (membranes, bolts, links), emphasizing CENTA as the supplier with the most multifaceted portfolio in the market. For...

CENTA PRODUCT DOCUMENTATION CENTA X-SEC RUBBER ELEMENTS The CENTAX-SEC rubber elements are composite parts made of thin, non-cutting shaped flanges with vulcanized elastomer. As ring elements they cover a torque range of 1-585 kNm and with an outer diameter of 1790 mm they are the largest available on the market. As segmented elements, for confined spaces, for short building and especially large couplings, they are available in the torque range of 22-650 kNm with an maximum outer diameter of 1940 mm.
