RGI Series

RGI series is the first fully self-developed infinite rotating gripper with a compact and precise structure on the market. It is widely applied in medical automation industry to grip and rotate the test tubes as well as other industries like electronics and New energy industry.

Products Features

Gripping & Infinite Rotation

The protection level of PGC series is up to IP67, so the PGC series is able to work under harsh conditions such as machine tending environment. 

Compact | Double Servo System

Dual servo systems are creatively integrated in a 50 × 50 mm machine body, which is compact in design and can be adapted to many industrial scenes. 

High Repeat Accuracy

The repeatability accuracy of rotation reaches ±0.02 degree, and the repeatability accuracy of position reaches ±0.02 mm. Through precise force control and position control, the RGI gripper can more stably complete the grasping and rotating tasks.
