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. The torques in the table are maximum values
for couplings with keyway. The calculations based on feather-key
connection.

For couplings without keyway: The transmittable torque is lower and
depends on how far the set screws penetrate the shaft.
