FHN Series Harmonic Drive Bearing FHN-14 for Industrial Robots

The FHN series is a lightweight product designed to be 20% lighter than standard models, making it an excellent choice for appliions where weight reduction is essential.

The lighter design allows for easier handling, installation, and transport, making it ideal for industries where mobility and space are crucial. This series is particularly beneficial in appliions where weight savings contribute to improved overall efficiency, such as in automotive manufacturing, robotics.

Despite its reduced weight, the FHN series maintains the durability and functionality required for demanding environments, offering a balance of strength and lightness.

Key Features

Ultra-Thin Section & Lightweight Saves space and reduces inertia-critical for collaborative robots (cobots) and high-dynamic appliions.
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 Lubried with low-outgassing, long-life grease (e.g., NSK AFA or equivalent)-ideal for cleanroom or vacuum environments.
Full Dimensional & Runout Inspection Report Includes certifies of conformity, roundness data, and preload verifiion-trusted by Tier-1 robot manufacturers.
OEM/ODM Supported Custom marking, packaging, or minor dimension tweaks available for qualified partners.
Proven in Real Robot Appliions Already deployed in 6-axis arms, surgical robots, and AGV steering modules across EU, Japan, and North America.
