SANKYO FH Series Rotary Pick and Place Part Handler


Sankyo is the worldwide leader in rotary pick and place part handling technology and continues to develop innovation in motion control. Our core indexing system is based upon the roller gear cam mechanism, a simple combination of a globoidal cam and cam followers in a precision machined turret. The profile of the cam and the rolling contact surfaces of the cam followers produce perfectly smooth and controlled motions.

We make our own internal components, the rotary indexer globoidal cam & needle bearing cam followers are optimized to the largest size for each configuration. Sankyo components are ~30% larger than the competition.

Our success is simple; larger diameters transfer more torque & rotate fewer revolutions. More surface contact & fewer revolutions have less wear to inherently extend the service life. Smaller units perform the same task with less cost.
