F-Series six beam couplings are designed for precision light-duty power transmission in motion control applications, such as connecting servo motors to lead screws. Their larger body size and reinforced six-beam design deliver higher torque capacity and reduced windup without compromising flexibility or misalignment compensation. Ideal for demanding reversing servo systems, these couplings help ensure accuracy, repeatability, and system reliability.

Manufactured by Ruland in the USA, F-Series couplings are available in lightweight 7075 aluminum for low inertia or durable 303 stainless steel for increased torque. Select models feature socket head cap screws with Ruland’s proprietary Nypatch® coating, which minimizes vibration, prevents thread loosening, and reduces galling in stainless steel assemblies.
