Sankyo P/PL Series Parallel Indexer & E/EL Oscillator

 

Sankyo is the worldwide leader in rotary indexing technology and continues to develop innovative motion control. Our core indexing system is based upon a plate cam mechanism, a simple combination of plate cams 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. Our P Series features a shaft output & the PL Series has a shaft & flange.

Why Sankyo
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.
