Helical’s 17-4PH stainless steel couplings are ideal when high strength, excellent fatigue resistance and high torsional stiffness are called for in an application. Helical is the only company offering a standard product line of beam couplings made of 17-4PH stainless steel. When compared to both 303 stainless steel and 7075-T6 aluminum, 17-4PH provides twice the torque and can operate up to 600° F, which is ideal when used for heavy duty applications such as lead screws, positioning systems, pumps and processing equipment. Helical couplings are machined from a solid piece of material, and when the unique HELI-CAL Flexure is incorporated they can compensate for angular, parallel or skewed misalignment, while providing axial compliance, constant velocity and smooth bearing loads.

Our series of couplings offer the engineer a large range for torque applications, or our engineers can design, develop and produce a custom HELI-CAL Flexure to meet your specific requirements. The W series (metric) from 1.2-39 Nm, the H series has a torque range from 2.4-100 lbin, and the MC series from 40-556 lbin. The MC Series has higher torque capacity and torsional stiffness and has two sets of flexures for increased parallel offset. This makes the MC series a great choice for conveyor systems, and industrial processing equipment where absolute reliability is required. All three series include configurations with reliefs, set screws, or integral clamp attachments.
