Thin Section Ball Bearings 6900 Series
The 6900 Series represents the light cross-section option, designed for applications where minimizing mass and inertia is the absolute highest priority.This series provides the most extreme space and weight savings in the thin-section family. Its minimal cross-section enables the design of exceptionally compact and lightweight mechanisms with low rotational inertia, allowing for very high acceleration and deceleration rates.
Applications:
The 6900 Series is engineered for the most demanding applications where minimizing mass, inertia, and spatial volume is the absolute priority. It is the definitive choice for ultra-lightweight robotic end-effectors, high-speed gimbal systems in aerospace and optics, and precision scanners in semiconductor manufacturing. This series enables maximum compactness and rapid acceleration in systems with strictly defined, light radial loads.
