Reaction Wheel (CW40K) (4Nms)
Price on request
CubeSpace (CS) offers a wide range of robust reaction wheels perfect for CubeSats and SmallSats. Our reaction wheel range is designed for precision performance, reliability, ease of use, and manufacturability. Featuring a modular, space-proven design with in-house designed motors, high-load space-rated bearings, and advanced lubrication, our wheels can be easily optimized to meet mission-specific requirements. This is achieved by adjusting the motor or using alternative bearings or lubrication and does not impact manufacturability due to this design’s built-in modularity.
Additionally, our wheels are meticulously balanced using our state-of-the-art automated laser balancing machine, ensuring outstanding vibration tolerance through stringent micro-vibration testing. This high tolerance, with the option for additional damping, makes our reaction wheels an ideal choice for missions requiring high precision and stability. With a distributed supply chain and automated production processes, the CS reaction wheel range offers robust, customizable, high-precision wheels that can be rapidly manufactured at high volumes and competitive pricing.
