  • Flexible Couplings

    • Light to medium duty
    • Non-magnetic
    • Economical
    • No maintenance
    The A Series coupling meets performance demands over a wide range of applications, including drive systems for encoders, instrumentation, lead screws, small pumps, feed rollers and anywhere a light to medium duty, torsionally flexible coupling is required. Helical's most popular coupling.

    • No maintenance
    • Shaft sizes from 3/32 to 3/4
    An array of options, in a variety of diameter sizes, allows you to tailor the A or H Series to your specific applications. A and H Series options include set screw or integral clamp attachments and inch or metric bores.

  • Helical H Series Stainless Steel Couplings

    • High torque capacity
    • High fatigue resistance
    • Corrosion resistant steel (CRES)
    The H Series coupling is ideal when high strength, excellent fatigue resistance and high torsional stiff ness is called for in your application. The H Series' premium performance capability is designed for applications requiring a heavy-duty coupling, such as drive systems, small pumps and gear boxes.

  • Helical DS Series Aluminum Couplings

    • High torsional stiffness
    • Low radial loads
    • Parallel misalignment capability
    • Low inertia
    The DS Series was designed for today's high performance motion control systems. This Series incor porates two helical beams in each of two separate HELI-CAL Flexures, combining greater end-to-end rotational accuracy with radial flexi bility in one design. Available only with integral clamp attachments, the DS Series provides the high torsional stiffness and low inertia necessary for positioning devices, servo motors and lead screws.

    The DS Series also provides you with substantial .010-inch parallel offset capability, reducing the need for high-precision alignment during assembly operations. It's your ticket to greater system accuracy and reliability. Available only in 7075-T6 aluminum.

  • Helical MC Series Aluminum Couplings

    • Industrial motor shaft couplings
    • Large parallel misalignment capacity
    • High torque capacity
    • Large shaft diameters
    • Keyways available
    This versatile series of couplings provides you with a full range of torque capacities and bore sizes, all with 1/32-inch parallel misalignment capability. These couplings attach to shafts with your choice of integral clamps or set screws. Combine this with optional keyways and the MC Series is tailor-made for your application.

    From medium-duty (aluminum) to heavy-duty (stainless steel), this series provides solutions for a wide range of applications. From pumps and lead screws to conveyors, chances are an MC Series coupling will fit your needs. Available in 7075-T6 aluminum alloy or 17-4 PH corrosion resistant steel (CRES)

  • Helical W Series Aluminum Couplings

    • Metric dimensions and fasteners.
    • Available in 7075-T6 aluminum alloy or 17-4 PH corrosion- resistant steel.
    • General purpose
    If you are working in the metric world, the W Series is for you. It combines the best features of the A Series and the H Series, with the convenience of metric dimensions and fasteners for your metric based designs. The W Series can be used in a wide range of applications from driving components with light torque requirements, such as encoders and tachometers (aluminum), to lead screws and pumps requiring greater torque (stainless steel).
