Specifications (Aluminum Alloy and Stainless Steel)
The datasheet provides specifications for Helix Couplings made from aluminum alloy and stainless steel. Key parameters include maximum torque, misalignment tolerance, stiffness, maximum rotation speed, moment of inertia, and mass. The aluminum alloy models range from MHC 015 to MHC 030, with varying torque capacities and dimensions. Stainless steel models also range from MHC 020 to MHC 030, offering higher torque capacities compared to their aluminum counterparts.

Dimensions
The document details the dimensions for each model, including bore diameters (d1, d2), outer diameter (D), length (L), and other critical measurements. Tightening torque for screws is specified for each model, ensuring proper installation.

Standard Bore Diameter
Standard bore diameters are provided for both aluminum alloy and stainless steel models. The datasheet includes a table showing nominal bore diameters and corresponding short-term torque values for each model, facilitating selection based on application requirements.

Ordering Information
Instructions for placing an order are included, specifying how to denote size, bore diameter, and material in the order code. Options for custom sizes and versions with blind bores are available upon request.

Additional Notes
The datasheet mentions that other sizes are available on request, and versions with blind bores can be provided. This flexibility allows for customization based on specific application needs.
