High-performance gearboxes of the series PSC and PSF they have planetary gears in one- and two-stage configurations, a specially developed offer from Sew Eurodrive for operation as part of servos. They are characterized by high accuracy, excellent torque performance and exceptional reliability in operation. A wide range of reduction coefficients in precisely matched integers. The design has a practical design in a compact and lightweight housing, exclusively high-quality materials are used to ensure resistance to large axial and radial loads.
Series PSF It has very low backlash and a wide range of operating parameters in eight overall versions. It is available in three types of low-speed interface design: PSF with solid smooth shaft, PSKF with solid shaft and keyway connection, PSBF flanged output (according to EN ISO 9409).
Series PSC These are the most flexible and economical gearboxes with low backlash, available in four dimensions, output interface: PSC large flange with solid smooth shaft, PSKC large flange with solid shaft and key connection, PSCZ with small flange and smooth shaft, PSKC small flange with solid shaft and key.
Both lines are mounted on synchronous servomotors of this brand without the need for an adapter, and modular connection units are also available for installation on other types of motors. Upon request, the necessary design changes can be made individually regarding the nominal data of the reduction and equipment of the model range.
