Nabtesco Cycloidal Gearboxes are designed for industrial applications where maximum precision, durability and torque density are essential. Their unique two-stage cycloidal reduction mechanism enables extremely high torque transmission within a compact footprint while providing outstanding positioning accuracy, high torsional rigidity and virtually backlash-free operation. These characteristics make them ideal for robotics, machine tools, automated production equipment and other demanding servo-driven systems.
The innovative dual-cam cycloidal design significantly reduces vibration and inertia while delivering exceptional resistance to shock loads. Nabtesco gearboxes can transmit rated torques of up to 28,000 Nm and withstand shock loads up to five times the rated torque. With hysteresis loss below 1 arcmin and pure backlash as low as 0.1–0.2 arcmin, they provide the precision required by the most demanding automation applications.
As the official Hungarian partner of Nabtesco, BIBUS Kft. provides engineering support for gearbox selection, sizing and integration. Our specialists help optimize the complete drivetrain to ensure maximum precision, reliability and long-term performance.
