Specifications (Aluminum Alloy)
The datasheet provides detailed specifications for Helix Couplings made from aluminum alloy. Key parameters include maximum torque, misalignment tolerance, stiffness, maximum rotation speed, moment of inertia, and mass for different models (MHS 015, MHS 020, MHS 025, MHS 030). Each model has specific values for short-term, one-sided, and reversing torque, as well as parallel, angular, and axial misalignment tolerances. The maximum torsional, radial spring, and axial spring stiffness are also specified.

Specifications (Stainless Steel)
Similar specifications are provided for stainless steel models, with higher torque and stiffness values compared to aluminum alloy models. The models maintain the same misalignment tolerances and maximum rotation speed.

Dimensions
The document lists the dimensions for each model, including minimum and maximum bore diameters, outer diameter (D), length (L), and other relevant measurements. Tightening torque for screws is also specified for each model.

Standard Bore Diameter
The datasheet outlines the standard bore diameters for both aluminum alloy and stainless steel materials. It includes nominal bore diameters and the corresponding short-term torque values for each model.

Ordering Information
Instructions on how to place an order are provided, specifying the size, bore diameter, and material (AL for aluminum alloy, VA for stainless steel).

Additional Notes
The document mentions that other sizes and versions with blind bores are available upon request.
