SCHUNK ELG Electric Long-Stroke Gripper Review: Specs, Price and Applications
The SCHUNK ELG is an electrically actuated, high-payload, long-stroke two-finger parallel gripper. Depending on size, it delivers 3,000 N (size 30) up to 12,000 N (size 120) of gripping force, and the stroke is continuously adjustable between 100 mm and 400 mm.
Because a servo motor drives the jaws, the ELG moves under position and torque control. One gripper can handle a wide spread of part sizes and geometries, and the motor can be selected to fit the controller platform already used in the plant.
Quick Verdict
One of the most capable electric grippers for heavy, bulky parts. Choose it when long stroke, very high force and programmable positions are needed in packaging, automotive, white goods or logistics.

Design and Operating Principle
The ELG is built around long guided base jaws driven by a servo motor. Electric actuation gives two advantages over pneumatic long-stroke grippers: jaw position is known at every moment, and gripping force is set by motor torque rather than by air pressure. That makes it possible to pre-position the jaws just outside the part width and close quickly, saving cycle time when stroke is long.
The configurable design means stroke and motor are chosen for the application rather than from a fixed list. The adaptable motor interface is a practical benefit: integrators can use a motor that runs on the plant's standard servo drives and fieldbus.
Food-compliant lubricants are used on gripper parts, but rolling bearings, linear guides and shock absorbers are not food-lubricated, and EN 1672-2:2020 is not fully met, which should be considered for hygienic areas.
Integration and Selection
Specify the smallest and largest part widths, part mass and centre of gravity, finger length and robot accelerations. Use these to choose the size and stroke, then confirm the guide moments with the actual fingers.
Plan the servo drive and controller integration: the gripper becomes an additional controlled axis, so motion parameters, torque limits and part-presence logic must be programmed and validated.
Industry Applications
Industry | Typical use |
Packaging | End-of-line case and bundle handling |
Automotive | Gripping large body and powertrain components |
White goods | Handling appliance housings and panels |
Logistics | Picking cartons and crates of varying size |
Functional Uses
Handling a wide range of part widths with one gripper
Programmable force for fragile and heavy parts
Pre-positioning jaws to cut cycle time
Part-size verification through jaw position
Pros and Cons
Advantages
Very high gripping force up to 12,000 N
Continuously adjustable stroke up to 400 mm
Position and torque control
Motor adaptable to existing control systems
Limitations
Large and heavy compared with standard grippers

Not fully compliant with hygienic design standards
Who Should Consider the SCHUNK ELG Electric Long-Stroke Gripper?
The ELG suits palletizing, logistics and heavy-part handling cells where a single electric gripper must cover many part sizes with high force and controlled motion.
Price and Availability
Price: Request a quote. SCHUNK prices the ELG 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.
