Diesel engine couplings
CENTAMAX
The CENTAMAX series is characterized by a highly efficient self-ventilating design. The high thermal capacity (HTC) design features a superior allowable power loss compared to other conventional couplings. This ensures longer equipment life in newer, more torsionally active low-emission diesel engine systems. The HTC design also makes CENTAMAX a cost-effective solution, as less costly coupling designs may be used in many applications. The torsional flexibility and elasticity of this rubber-in-shear design shifts critical resonances below operation speed. The drive is then subject to only minor continuous vibratory torques, protecting and extending the life of your equipment. Rubber elements for the CENTAMAX are available in different degrees of shore hardness. CENTAMAX elements are also offered in higher temperature CENTALAN-HT or silicone if required. This enables easy adjustment of the torsional flexibility of the couplings. Torsional vibrations are damped, and resonance reduced, minimizing the impact on your driven equipment. CENTAMAX is built with overload protection. Under extreme loads caused by torque overloads or generator short circuits, the flexible coupling slips through cogged outer teeth, protecting the engine and surrounding units from overload damage. CENTAMAX includes many plug-in variations for simple assembly with minimal mounting effort. The hubs can be customized to various mounting and application conditions. Built with the highest standards in design and quality, CENTAMAX coupling systems are the reliable choice.
