• Inch and metric Feather keys

Feather Keys are well known in Europe and elsewhere in the world but not in the USA. They are used for shafts from 1/4" diameter up to 2-1/2" diameter. The Feather key torque capacity is the same as square and rectangular parallel keys.

The Feather key is similar to the parallel key except that they are radiused on both ends and machined to tight length tolerances. The mating key slot in the shaft is machined with an end mill cutting tool and machined to the same length as the Feather key.

The broached keyway in the mounted component is identical to conventional keyways used for parallel keys. So there are no changes to components are needed except for the shaft.

The unique advantage of the Feather key over all of versions of Parallel and Woodruff keys is that when the key is installed it is totally contained and cannot shift out of position. Additionally, the Feather key is easy to insert in the shaft and it is simple to assemble the component onto the shaft.
