REC Hallow Shaft Slip Ring- Model RH25 Series Inner diameter : 25 mm 

RH25 Series central hole Slip Ring can be used in any electromechanical system that is requiring unlimited, continuous rotation for transmitting power and signal data from a stable structure to rotational structure. With a hole diameter as 25mm, the product can be easyly mounted on a shaft. Also, the fiber brushes do not require lubrication and maintenance,almost no wearing down during it's life time.This type of slip ring uses a bunch of fiber brush technology in the ring and a few of the brushes and rings contact is provided on a point. This ensures long lifetime and uninterrupted transmission.
