RM-EGB Mini Electric Fingers
User Manual
Advantages of Electrical Actuators
Easier Wiring
Can be directly substituted for pneumatic grippers.
Highly Integrated
No need for additional equipment configuration.
Easier Programming
Can achieve motion with uniform speed at multiple positions.
Longer Service Life
Less downtime and higher equipment utilization rate.
Lower Maintenance costs
Compact and simple structure; Less difficulty in fault detection
Reduced Noise Levels
Driven by servo motors and avoiding pneumatic noise.
Better Performance
The control accuracy is higher and movement is stable that able to improve
product yield. Best Replacement For Pneumatic Fingers
RM – EGB is highly integrated with servo system inside . It can replace
pneumatic grippers, which are composed of an air compressor, filter, solenoid
valve, throttle valve, and pneumatic cylinder. Wide rang of Clamping Force

Suggestions About Fixture Design
For the distance (L, H) from the mounting surface of the motorized gripper jaw
to the gripping point, please make sure it’s within the range shown in the
chart below.
Please note that when exceeds the limit range , it will cause excessive load
torque on both the slider of the electric actuator and the internal mechanical
structure, which may reduce tservice life of the product .
- When designing or selecting jigs and fixtures, it is recommended to choose jigs and fixtures as small and light as possible .
- when using out- of- range or over- weight fixtures, it will cause gripper to suffer from excessive opening and closing inertia forces and bending load moments, resulting in negative impacts such as performance degradation or shortened the service life of guide rail .
