Product Description

FBS-U-C Series Harmonic Drive Bearing FBS-U-C-11 for Industrial Robots

The FBS-U-C Type is a versatile, high-performance harmonic reducer designed to handle a broad range of industrial requirements.

Building on the core FB Series technology, the FBS-U-C offers a wider selection of sizes and ratios.

It is engineered to withstand extreme pressure without grease failure, thanks to its enhanced load-bearing capabilities and customizable backlash settings, ensuring the reducer remains in optimal condition regardless of the operational environment.

Key Features

Increased Load Capacity: Leveraging the FB tooth profile, the FBS-U-C delivers a 15% increase in load-bearing capacity compared to standard profiles, making it suitable for demanding dynamic loads.
Optimized Performance: The design prevents grease failure under extreme pressure by minimizing sliding friction.
Flexible Configuration: During development, the flexspline tooth profile is matched to the radial displacement of the generator, allowing for precise backlash adjustment to suit specific application conditions.
Easy installation and integration – The unit type design simplifies assembly and ensures stable performance, minimizing errors caused by misalignment.
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.
