Product Description

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

The FBS-U-Ⅰ Type represents a leap forward in harmonic reducer technology, featuring the advanced FB Series Double Circular Spline design. Engineered for compact precision, this series utilizes a revolutionary multi-segment continuous curvature tooth profile.

This geometric optimization ensures superior meshing accuracy and significantly reduces relative sliding friction, making it an ideal choice for applications requiring longevity and stability in a compact footprint.

Key Features

Advanced Tooth Profile: Transforms traditional two-segment arcs into a multi-segment continuous curvature curve, ensuring optimal gear meshing and reducing friction.
Extended Durability: The optimized contact mechanics reduce the gear fatigue pitting area by over 30%, extending the continuous running-in service life to exceed 15,000 hours.
Thermal Efficiency: The low-friction design effectively mitigates heat generation, reducing operating temperature rise by 8-10℃, protecting lubricant integrity even in confined spaces.
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.
