G Series Walking Beam Linear Parts Handler

 

Sankyo is the worldwide leader in linear walking beam 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.

Application

• Multiple walking beam handlers can be synchronized with a common drive to feed large parts accurately
• Single walking beam handlers can be used with short beams with minimal bending moment capacity
• The parts may be handled by the bottom or the sides

Why SANKYO
We make our own internal components, the rotary handler 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.
