Shafts with keyway offer increased protection against rotation, especially for applications where the load changes direction. For shaft diameters of 6.35 mm and more, keyways are manufactured according to DIN 6885 P9. 

The keys are available as an accessory.

Thinner shaft

Machined shafts are used when toothed wheels, pinions or pulleys with small bore diameter are to be directly attached to the motor shaft.

A motor with two shaft ends is necessary for the subsequent machining of a shaft.
