SCHUNK EGS Electric Rotary Gripper Review: Specs, Price and Applications
The SCHUNK EGS is an electric two-finger parallel gripper combined with a swivel module. It grips and rotates small to medium workpieces in one compact unit, with flexible gripping force and high speed for clean environments.
Combining gripping and swivelling in one electric module removes an extra rotary axis from the tooling. That keeps the end effector short and light, which is valuable on small robots and in pick-and-place cells where every gram affects cycle time.
Quick Verdict
A tidy solution when parts must be gripped and reoriented in the same move. Electric control makes it attractive for laboratory, pharmaceutical and electronics applications where compressed air is unwanted.

Design and Operating Principle
In the EGS, an electric drive closes the parallel jaws and a second function swivels the gripper. The result is a compact grip-and-turn module: the robot can pick a part, rotate it to the required orientation and place it without a wrist move or an additional rotary actuator.
Electric actuation allows the gripping force to be adapted to the part, which matters for delicate components such as vials, sensors or plastic housings. It also removes the need for compressed air, reducing noise and contamination risk in clean areas.
Parallel jaw motion keeps finger contact faces aligned during closing, so the part does not shift sideways. This is helpful for precise placement in test sockets or assembly nests.
Integration and Selection
Check part mass, finger length and the inertia during swivelling. Swivel speed and the part's distance from the rotary axis determine the loads on the jaws, so lightweight fingers help.
Plan electrical connection and control signals for both the gripping and swivel functions, and confirm end positions in the robot program before release.

Who Should Consider the SCHUNK EGS Electric Rotary Gripper?
The EGS suits automation engineers in assembly, testing, laboratory and pharmaceutical applications who need compact grip-and-turn handling without compressed air.
Price and Availability
Price: Request a quote. SCHUNK prices the EGS by size, options and quantity, so the final figure depends on the exact configuration. Budget for the complete tooling package, including fingers or adapters, mounting, air or electrical connections and commissioning time, rather than the module alone.
