FSG-14 Crossed Roller Bearings for Harmonic Drive with Zero Backlash High Rigidity and P4 Precision for Industrial Robots
The FSG High Torque Harmonic Reducer is Drive’s dedicated High Torque product line, engineered to deliver superior performance for demanding applications.
Building on the proven design of the standard series, the G Series incorporates advanced tooth profile optimization and material enhancements to significantly boost load capacity and durability.
It is the ideal solution for precision motion control requiring higher torque density and longer operational life without increasing the physical size of the gearbox.
Significantly Increased Torque: The FSG features a specialized high-load capacity design. Compared to standard models, the torque output capability is increased by 30%. This allows for the use of smaller gears to drive heavier loads, optimizing space and weight in your machinery.
Extended Service Life: Engineered for endurance, the FSG offers exceptional durability. The service and maintenance time is extended by 43%, ensuring long-term reliability and reduced downtime for industrial automation and robotic systems.
Precision & Efficiency: Maintains the core advantages of Laifual harmonic Reducers, including zero backlash, high positioning accuracy, and high efficiency transmission.
Versatile Options: Available in a wide range of sizes and reduction ratios to suit various specific requirements.
- 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.
