    F-Series Six Beam Couplings

    F-Series six beam couplings are ideal for light duty power transmission applications such as coupling a servo motor to a lead screw in a motion control system. These flexible couplings feature larger body size and stronger beams to provide high torque capacity and low windup, while not sacrificing misalignment capabilities. The demanding nature of reversing servo applications make the performance benefits delivered by the F-series beam coupling vital to maintaining the accuracy, repeatability and reliability of the system. F-series helical couplings with socket head cap screws include Ruland's exclusive Nypatch® coating. This coating reduces vibration which can cause threads to loosen, and reduces galling of the screw threads in stainless steel shaft couplings. Ruland manufactures F-series beam couplings from 7075 aluminum for lightweight and low inertia and 303 stainless steel for increased torque capabilities.
