Beam Couplings

The Flexible Beam Coupling by Helical Products

The Flexible Beam Coupling was invented by Helical Products in 1958 when George Sabadash conceptualized a single piece flexible coupler, or “Beam Coupling”. The rest is history as Sabadash was joined by a group of engineers to perfect and market the world standard in flexure beam couplings. Read the full story here.

Helical Products Co. is the originator of the flexible beam coupling and remains the world wide industry leader in beam coupling technology and innovation. We offer a vast range of standard beam couplings as well as the ability to create custom couplings to meet our clients exact specifications.

Beam Coupling

W Series Couplings

W Series Beam Coupling

W series flexible beam couplings are excellent for general purpose, light to medium duty. An economical, maintenance free coupling, used in a variety of applications. Available in either 7075-T6 aluminum alloy or 17-4PH stainless steel. The stainless steel version offers a higher torque capacity and torsional stiffness as well as increased fatigue resistance.

DS Series Couplings

DS Series Helical Beam Coupling

DS (Double Start) series beam couplings are a low inertia, high performance, aluminum coupling, that utilize a helical double start technology. The DS series is torsionally stiffer and higher torque capacity than the "A" series. They are lighter and feature lower inertia than the "H" series.

MC7 Series Couplings

MC7 Series Flexible Beam Coupling

The MC7 series beam coupling is a stainless steel version of "MCA(C)" series, with higher torque capacity and torsional stiffness plus increased fatigue resistance due to the material used. The MC7 is a rugged, tough, long-lasting coupling that can be used for pumps, conveyor systems, or industrial processing equipment, where absolute reliability is required.

H Series Couplings

H Series Beam Coupling

The H series beam coupling ia a stainless steel version of the "A" series, with higher torque capacity and torsional stiffness as well as increased fatigue resistance. The H series is ideally suited for situations requiring a heavy duty coupling, for pump, lead screws, and positioning systems. Also for process equipment in industrial situations where a rugged, tough, long-lasting coupling is needed.
