    About

    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.

    F-Series Six Beam Couplings
    P-Series Four Beam Couplings

    P-series beam couplings are designed specifically for precision applications, such as encoders and tachometers that use delicate components. The small bearings on these components make low radial forces essential to longevity and continued high performance. They provide extra flexibility to yield reduced bearing loads. These flexible couplings are shorter than the F-series six beam couplings and conform to industry standard lengths, fitting into confined spaces and allowing for easy retrofits in existing equipment. At the same time, the helical cut pattern continues to provide excellent torque capabilities and low wind-up. P-series beam couplings are manufactured from a single piece of 7075 aluminum for lightweight and low inertia or 303 stainless steel for increased torque capabilities.

    P-Series Four Beam Couplings
    MW-Series Four Beam Couplings

    MW-series four beam couplings differ from the P-series because they have pure metric outer diameter and length dimensions. Like the P-series, they are designed for precision applications, such as encoders and tachometers that use delicate components. The small bearings on these components make low radial forces essential to longevity and continued high performance. They provide extra flexibility to yield reduced bearing loads. These flexible couplings are shorter than the F-series six beam couplings and conform to industry standard lengths, fitting into confined spaces and allowing for easy retrofits in existing equipment. At the same time, the helical cut pattern continues to provide excellent torque capabilities and low wind-up.

    Why Ruland Beam Couplings?

    • Ruland clamp style beam couplings have reduced vibration at speeds up to 6,000 RPM due to a balanced design.
    • The highest size-for-size torque and torsional stiffness in the industry based on our proprietary beam design.
    • Coupling screws will not loosen during operation when using clamp style, six-beam couplings, which are treated with Ruland's performance-enhancing Nypatch® anti-vibration coating.
    • Ruland ensures superior product craftsmanship by manufacturing beam couplings from meticulously selected North American bar stock.
    • Ruland engineers have designed hundreds of custom solutions if a standard part does not match your application requirements.
    • True ratings based on actual testing.
