SCHUNK SGW Plastic Angular Gripper Review: Specs, Price and Applications
The SCHUNK SGW is a small, simple angular gripper made of plastic. It is actuated by compressed air and returns by spring, giving a lightweight and economical gripper for universal applications in clean and slightly dirty environments.
Its plastic construction brings corrosion resistance and an anti-static gripping unit, which suit electronics handling and environments where metal grippers would corrode.
Quick Verdict
A lightweight, low-cost angular gripper for simple pick-and-place tasks. Choose it where low mass, corrosion resistance or anti-static properties matter more than high gripping force.

Design and Operating Principle
The SGW is single-acting: air pressure drives the jaws in one direction and a spring returns them. This halves the valve and tubing requirements compared with double-acting grippers and gives a defined jaw position when air is switched off.
A plastic body keeps the gripper light, which benefits small robots and fast pick-and-place axes. Plastic also resists corrosion in humid or washdown-adjacent areas, and the anti-static properties protect sensitive electronic components from discharge.
As an angular gripper, the jaws open on an arc, giving easy approach to the part. Gripping force is modest compared with metal grippers, so the SGW is best for light parts.
Integration and Selection
Confirm the required gripping force with the actual finger length and the spring's return force, since spring return reduces the effective force in one direction. Plan whether the spring should open or close the gripper when air is lost.
Use a simple 3/2 valve and lightweight fingers; plastic housings also call for appropriate screw torques when mounting.
