The highest level of precision, torque and overhung load: Low backlash planetary and helical-bevel servo gear units
The low backlash PSC planetary servo gear units are designed for the 30 to 350 Nm (265 to 3100 lb-in) torque classes. They were designed to combine the greatest possible flexibility and cost-efficiency because not every application requires high-performance components. They provide a basis for diverse, dynamic and cost-optimized drive solutions. The PSC planetary servo gear units are available in the following versions: PSC = B5 output, smooth output shaft PSKC = B5 output, with keyway PSCZ = B14, output, smooth output shaft PSKCZ = B14 output, with keyway
