1000809AKIT2 flexible ball bearing belongs to AKIT2 special‑cage harmonic‑drive‑bearing series. Realizes periodic reversible elliptical‑elastic‑deformation and resists complex alternating‑stress‑load. Optimized‑cage reduces rolling‑element‑wear during‑deformation‑rotation, suitable for medium‑size robot joints and high‑precision harmonic‑positioning‑equipment.
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.
