Product Description

FHD Series Harmonic Drive Bearing FHD-8 for Reducer

Compared to conventional designs, the FHD-I model reduces axial length by 50%, while the FHD-III achieves a 15% reduction, all without compromising product performance.

This compact and efficient configuration makes the FHD series an ideal choice for precision machinery, robotics, and automation systems requiring space-saving, high-torque, and reliable harmonic reducer solutions

Key Features

Ultra-Thin Section & Lightweight Saves space and reduces inertia-critical for collaborative robots (cobots) and high-dynamic applications.
Precision Ground & Preloaded All raceways ground to IT5 tolerance; preloaded to eliminate clearance-ensures zero backlash and smooth motion.
High-Quality GCr15 / SUJ2 Bearing Steel Heat-treated to HRC 58-62 with super-finished surfaces for long fatigue life under cyclic loading.
Cleanroom Assembled & Vacuum Greased Lubricated with low-outgassing, long-life grease (e.g., NSK AFA or equivalent)-ideal for cleanroom or vacuum environments.
Full Dimensional & Runout Inspection Report Includes certificates of conformity, roundness data, and preload verification-trusted by Tier-1 robot manufacturers.
OEM/ODM Supported Custom marking, packaging, or minor dimension tweaks available for qualified partners.
Proven in Real Robot Applications Already deployed in 6-axis arms, surgical robots, and AGV steering modules across EU, Japan, and North America.
