FSS Series Harmonic Drive Bearing FSS-5 for Industrial Robots

The FSS series harmonic reducer unit is a high-precision gear reduction solution consisting of three core components: the cup-type flexspline, circular spline, and wave generator. Its compact and lightweight structure makes it ideal for applications where space and weight constraints are critical, such as robot joints, precision automation, medical devices, and aerospace systems.

Key Features

Compact and lightweight design – The integrated structure achieves minimal size and weight, making it perfect for restricted installation spaces.
High transmission accuracy with low backlash – Harmonic Reducer technology ensures superior positioning accuracy and repeatability, enabling precise motion control.
High rigidity and load capacity – Each model is equipped with crossed roller bearings, capable of withstanding radial, axial, and moment loads simultaneously, while reducing the need for additional bearing systems.
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.
