FH Series Hollow-Shaft Harmonic Drive
The FH Series is a new generation of hollow-shaft harmonic drives made for high-performance motion control systems. It uses an ultra-short tube structure, flange-mounted design, and an integrated hollow bore to achieve compact size, high torque, and excellent efficiency. Cables, pipes, or wires can pass directly through the hollow shaft. This feature simplifies assembly and improves system layout. The lightweight housing and refined flexspline structure lower inertia while keeping strong torque output and high positioning accuracy. The FH Series suits robotic joints, automation lines, semiconductor tools, and precision machinery where both space and precision are important. Each model ensures smooth motion, long service life, and reliable performance under continuous operation.
High-Torque Harmonic Drives for Advanced Motion Control
The FH Series Harmonic Drives represent Laifual’s next-generation solution for high-precision hollow-shaft applications. Designed as the equivalent of the SHG, SHF, and SHD series, the FH Series brings together power, precision, and versatility in a compact, lightweight form. It meets the growing demand for motion systems that require high torque, large hollow bores, and seamless integration within limited spaces.
Hollow type FHT
Compact Strength and Intelligent Design
Each model in the FH Series is built with Laifual’s proven cup-type flexspline technology and a large hollow-shaft design that supports easy cable and pipe integration. This structure simplifies installation, reduces clutter, and enhances system efficiency. With smooth operation, long service life, and high torque performance, the FH Series delivers a compact, reliable, and high-performance harmonic drive for modern automation systems.
Ultra-Short Structure, Maximum Power
With its shortened flexspline and flange configuration, the FH achieves a remarkably compact profile. Models such as FHD-I cut axial length by up to 50%, while FHD-II reduces it by 15%, all without sacrificing torque output or stability.
Lightweight Build with High Torque Output
Refined engineering and optimized materials make the FH Series up to 20% lighter than standard designs. At the same time, torque capacity increases by up to 30%, and service life extends by over 40%, delivering outstanding performance for fast, demanding motion systems.
Reliable Precision for Continuous Operation
Every FH reducer combines high torsional rigidity, precise motion control, and low vibration performance. Its durable internal structure ensures smooth transmission and consistent accuracy throughout long operating cycles.
