Product Description

The RHPH0128 harmonic drive, part of the RHPH series gearbox, is a high-precision speed reducer optimized for robotics, aerospace, and industrial automation. Featuring 1 input and 1 output port, it integrates directly with servo or stepper motors, operating at 12-48V DC within -20°C to +85°C. This compact unit delivers zero-backlash performance, 30 Nm torque capacity, and over 85% transmission efficiency. While excelling in space-constrained applications with ±1 arcmin accuracy, it lacks integrated communication interfaces and requires specialized maintenance. The RHPH0128 speed reducer supports standard mechanical interfaces but does not incorporate battery capacity, screen displays, or detection sensors, focusing solely on precision motion transfer in demanding environments.
