Specifications
The datasheet provides specifications for rigid couplings, specifically the STK models. These couplings are available in two types: Sliced (one-piece) and Split (two-piece), and are made from either steel (ST) or stainless steel (VA). The maximum torque values range from 30 N·m to 5000 N·m, depending on the model. Proper use, including material and dimensional accuracy of the shaft, is necessary to achieve these torque values. Maximum rpm is dependent on material and size.

Dimensions
The dimensions for each model are provided, including the inner diameter (Di), outer diameter (Da), length (L), and the number and size of screws (R and C). For larger models (STK-40 and above), the slit for sliced couplings is on the outside.

Ordering Information
To place an order, the model number should include the size/bore diameter, type (GS for Sliced, GT for Split), material (VA for Stainless steel, ST for Steel), and any options (N for with keyway, blank for no keyway).
