ENGINEERED FOR ACCURACY. BUILT FOR INTEGRATION.
Cone Drive’s Harmonic Gearing Solutions® deliver ultra-compact, high-precision motion control with zero backlash and exceptional torque density. Offered in a variety of configurations, these fully customizable solutions are proudly made in America to meet the demands of robotics, automation, and space-constrained applications.
Cone Drive’s cup-style harmonic gearing solutions are designed for compact, high-torque applications requiring precise, zero-backlash motion control. In this configuration, the torque is transmitted through the closed (bottom) surface of the cup, providing a lightweight, space-efficient solution ideal for tight integration.
The CBC, CBCF-, CBC-L, CBG, and CBGF- series offer features such as integrated cross-roller bearings and industry-standard mounting interfaces—and are fully customizable to meet specific application and performance requirements.
Cone Drive’s hat-style harmonic gearing solutions are built for high-precision, high-torque applications where smooth motion and robust load handling are essential. In this configuration, the torque is transmitted through the flanged brim of the hat, providing a stable and accessible interface for integration.
The HBC, HBCF-, HBG, HBGT-, and HBGHL series include options such as housed outputs, large hollow shafts, sealed designs, and integrated cross-roller bearings—making them ideal for robotics, automation, and demanding industrial environments. These solutions are fully customizable to meet unique space, torque, and performance requirements.
Cone Drive’s ring-style harmonic gearing solutions—RLC and RBC—are designed for applications requiring a compact, high-precision solution with flexible integration. In this configuration, the load is supported through the outer ring, with mounting typically done on the circular shaped ID Spline, allowing for seamless integration into rotating systems such as turntables or positioning platforms.
The RLC offers an ultra-compact design, while the RBC provides increased torque capacity in while maintaining a compact footprint. Both models are fully customizable to meet exact torque, ratio, and mounting interface requirements—making them ideal for robotics, automation, and space-constrained systems.
Cone Drive’s integrated harmonic actuator solutions—including the GMA-H, GMA-S, and Harmonic cup with NEMA stepper motor—combine high-efficiency motors with precision harmonic gearing in ultra-compact assemblies. These solutions offer excellent power density, zero backlash, and flexible mounting options, with the GMA-S optimized for lightweight applications and the GMA-H designed for higher torque needs. The Harmonic Stepper model integrates directly with NEMA stepper motors, providing a ready-to-use, space-saving solution for robotics, automation, and compact motion systems.
All models are fully customizable to meet specific performance and envelope requirements.
