FS‑32 flexible ball bearing meets large compact harmonic reducer requirements. It undergoes repeated elliptical elastic deformation and complex alternating stress inside wave‑generator assembly. P4 high‑precision strictly controls running error. Widely matched for large cobot joints, hollow harmonic drives and industrial precision rotary assemblies.

Flexible ball bearings feature thin-walled flexible rings that undergo controlled elastic deformation during operation, enabling precise motion transmission through wave generator assemblies. Available in standard, ultra-thin, and high-fatigue designs, with bore diameters ranging from 20mm to 300mm. These bearings deliver high torsional stiffness, zero backlash, and exceptional positional accuracy, making them ideal for harmonic drive reducers, robotics joints, aerospace actuators, and precision positioning systems.
