pick-and-place materials handling module by Sankyo America

Sankyo's GY series features narrow cast iron housings with upright, inverted or side mounting configurations since it is grease lubricated. Globoidal cams rotate Sankyo manufactured needle bearing type cam followers. Optimizing the cam follower diameter inherently maximizes torque transfer and extends the life hours due to fewer rotations with increased surface contact. A full cycle (home-pick-place-home) is done with one input shaft revolution to easily synchronize with other equipment and share a common drive. The output arm is a linear slide mounted with multiple bearing blocks that support large bending and twisting moments to maintain rigidity. Offset tooling or multiple grippers mounted on beam are common applications. These units can apply forces in both directions within ±0.02 mm (±0.0008") repetitive accuracy. Vibration can cause flats on the cam and cam follower surfaces due to constant positive and negative torque forces. Our units dissipate vibration by using large mass internal components and rounding the X-Y motions transition to enhance the overall life span. All motions are customized to your application without extra cost.
