FD‑32 FD‑series modified flexible ball bearing is developed for large‑size non‑standard harmonic reducers. Realizes reversible elliptical elastic‑deformation and resists severe cyclic alternating‑stress. Strict precision‑control maintains positioning‑accuracy, applied for custom‑built large robot joints and special‑layout harmonic rotary platforms.

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.
