Answers about flexible gripping.

Servo-Flex is a Belgian manufacturer of flexible servo-electric grippers for industrial robots and cobots. Its grippers grip parts from 6 to 120 mm with one jaw configuration, deliver up to 5 kN per jaw, and hold the part mechanically even on power loss.

Three things: flexibility (one gripper covers 6–120 mm with no jaw changes), light weight (2–4 kg, which recovers robot payload), and a patented mechanical hold that keeps the part gripped without power or air.

Servo-Flex is designed and engineered in Belgium. It grew out of AFP Usinage, a precision CNC machining workshop, and its mechanical clamping system is patent pending.

The Flexi 100 is a 2 kg, 2-jaw gripper for industrial robots and cobots, handling parts up to 30 kg. The Flexi 150 is a 4 kg, 3-jaw self-centering gripper for industrial robots and cobots, handling parts up to 40 kg. Both grip a wide diameter range with one configuration.

Up to 5 kN per jaw — about 500 kg — adjustable across three levels (light, medium, max) to protect delicate parts or hold heavy ones.

Diameters from 6 to 120 mm with a single jaw configuration, and part weights up to 30 kg (Flexi 100) or 40 kg (Flexi 150) depending on overhang.

All major industrial robots and cobots, including Fanuc, ABB, KUKA, Universal Robots, Yaskawa, Stäubli, Doosan and Omron, via standard ISO 9409-1 flange adaptation and 24 V digital I/O.

No. Servo-Flex is fully servo-electric. There are no air lines to route and no pneumatic maintenance — only programmable electric control.

Over simple digital I/O from the robot or PLC, with selectable force levels. No specialised fieldbus is required for basic operation.

Nothing — it stays held. The clamping force is locked mechanically rather than by continuous power or air, so a power loss never drops the part.

Yes. It is force-limited with adjustable levels, marks the gripping zone with blue safety LEDs, and holds the part mechanically, making it suitable for collaborative and unattended cells.

By removing jaw changes, cutting gripper references, and recovering robot payload, it raises uptime and throughput. Most cells see a return within a few weeks, with production gains up to 10%.

Replacing a heavy gripper with a 2–4 kg Servo-Flex can free several kilograms. For example, swapping a 12 kg gripper for a 4 kg one on a 40 kg robot raises usable payload from 28 kg to 36 kg.
