GIMATIC GS Series Self-Centering Parallel Gripper Review: Specs, Price and Applications
The GIMATIC GS series is a double-acting, two-jaw self-centering pneumatic parallel gripper built for long, maintenance-free service in pick-and-place, assembly and packaging automation.
Its standout feature is a backlash adjusting system that lets the jaw play be taken up over time. The GS is offered with spring-closed (-NC) or spring-open (-NO) versions, several fastening options, optional magnetic sensors and FDA-H1 food-grade grease.
GIMATIC, based in Italy, is a long-established specialist in grippers, vacuum components and end-of-arm tooling, and the GS is one of its core pneumatic gripper families.
Quick Verdict
A dependable general-purpose pneumatic gripper whose adjustable backlash keeps accuracy consistent across a long service life, with useful food-grade and fail-safe options.

Design and Operating Principle
Self-centering means both jaws move symmetrically toward the gripper axis, so a part is always located on the same centreline regardless of its width. That simplifies robot teaching because the tool centre point stays fixed for a part family.
Jaw guides inevitably wear over millions of cycles, and play in the guide shows up as positioning error at the fingertip. The GS backlash adjusting system allows that play to be reduced, preserving placement accuracy without replacing the gripper.
Double-acting actuation gives full air force for both opening and closing. Where a part must not drop on air loss, the -NC version adds a spring that keeps the jaws closed; the -NO version keeps them open, which can be useful for safe recovery after an emergency stop.
FDA-H1 grease makes the GS appropriate for food and packaging lines, where incidental contact with lubricant must be acceptable.
Integration and Selection
Size the GS from the required gripping force at the actual finger length, including acceleration and a safety factor. Friction grips need much more force than form-fit fingers that cradle the part, so finger design often decides the gripper size.
Choose the fastening option that suits the tool plate, add magnetic sensors for open/closed confirmation, and select -NC or -NO according to the machine's risk assessment.
