Material: Stainless steel 1.4305 (AISI 303).

These couplings do not allow any shaft displacement in axial or radial direction. They should therefore only be used with perfectly alligned shafts. Bore tolerance: +0,05 mm. Feather Key Groove DIN 6885/1, Tolerance P9. The torques in the table are maximum values for couplings with keyway. The calculations based on feather-key connection.
