    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. MW-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.

    Why Ruland?

    • Higher torsional rigidity than commodity style single-beam couplings.
    • Unique balanced clamp screw design reduces vibration while the cross cut increases clamping ability.
    • Machined from a single piece of aluminum or stainless steel with multiple spiral cuts for higher torsional stiffness and torque capabilities.
    • Accommodates parallel misalignment, angular misalignment and axial motion.
    • Two sets of cuts around center member better accommodate parallel misalignment than single beam couplings.
    • Four beam and six beam couplings offered. Four beam couplings are more flexible with lower bearing loads. Six beam couplings have increased torque capacity and higher torsional stiffness.
    • Aluminum couplings made from type 7075 aluminum for longer life.
    • Stainless steel couplings offered for greater torque capacity.
    • All Ruland beam couplings are RoHS3 and REACH compliant.
