FR|2 fingers gripper
The most compact 2 finger pneumatic gripper in its specification class — engineered for CNC machine tending, robotic assembly, and pick-and-place automation. FOUK's FR Series is part of our Pneumatic Grippers lineup, delivering patented 3-tooth guide rail precision, 0–130 kg gripping capacity, and a modular options system that adapts to your harshest production environment.
1. 3-Tooth Toothed Guide Rail Structure
FOUK's patented three-tooth rail replaces the conventional T-slot groove found on most 2 finger pneumatic grippers. By distributing lateral loads across three engagement points instead of one, the FR series achieves 40%+ higher bearing capacity, tighter centering accuracy, and dramatically extended service life under eccentric loading — the kind that occurs in real CNC machine tending cycles.
2. Wedge Drive Actuation
The FR series uses a precision wedge drive mechanism to convert pneumatic cylinder force into jaw clamping force. This design delivers high grip force from a compact body — achieving the smallest form factor in the industry for its specification class, enabling integration into tight machine tool envelopes where standard parallel grippers cannot fit.
3. Aerospace-Grade Aluminium + Hard Anodizing
All FR series bodies use 7075 aerospace-grade aluminium with hard anodize surface treatment — providing the strength-to-weight ratio of high-end aviation components while resisting corrosion, coolant ingress, and abrasive wear from metal chips. No weight-saving shortcut is taken on the structure that holds your workpiece.
4. Modular Optional Modules System
Unlike competitors who offer a fixed gripper design, FOUK FR is built around a modular platform. Dustproof seals, gas fail-safe self-lock, high-temperature resistant seals, bottom exhaust ports, and short-stroke pistons all bolt on without modifying the core gripper body — protecting your investment when production requirements change.
Every production environment is different. FOUK's modular system lets you configure your 2 finger pneumatic gripper precisely for your application — without custom tooling or lead-time penalties.
1. Dustproof Module
Full sealing of the jaw guide slot against metal chips, coolant splash, cutting oil, and dust. Essential for CNC machine tending environments where swarf contamination is a primary cause of parallel gripper premature failure.
2. Gas Fail-Safe Self-Locking
Maintains jaw clamping force even in the event of compressed air supply loss or hose failure. Critical for applications where a dropped workpiece would cause injury, machine damage, or production line stoppage. No external power required to maintain lock.
3. High-Temperature Resistance
High-temperature sealing compounds and heat-resistant coatings allow operation in forge, casting, and heat treatment environments where standard pneumatic parallel gripper seals would degrade. Consult FOUK engineering for specific temperature range confirmation.
4. Short-Stroke / High-Force Variant (S Series)
Reduced jaw travel with proportionally higher clamping force — ideal for gripping heavy or high-friction workpieces where maximum grip security matters more than jaw opening range. Available for all FR bore sizes.
5. Bottom Exhaust Port
Redirects exhaust air downward (rather than to the side), preventing chip and coolant blow-back into sensor and solenoid areas. Simplifies installation in compact machine tool enclosures with limited side clearance.
6. Magnetic Piston Sensor Compatibility
Integrated sensor slots in the gripper body enable easy mounting of open/close position sensors — compatible with standard reed switch, Hall-effect, and inductive proximity sensor types. Plug-and-play position feedback for robot I/O without external brackets.
1. CNC Machine Tending
The FR series' compact form factor — the smallest in its class — integrates directly into lathe and machining center tool magazines. Automates raw material loading, finished part unloading, and inter-machine transfer. Dustproof module recommended for coolant exposure.
2. Industrial Robot Pick-and-Place
The most common 2 jaw pneumatic gripper application. FR16–FR32 models cover the 0–50 kg payload range typical of 6-axis industrial robot wrist loads. Standard ISO flange interfaces for FANUC, KUKA, ABB, Yaskawa, and more. Fast cycle times under 0.1s.
3. Electronics & Semiconductor Assembly
FR16 and FR20 parallel grippers provide the precision and repeatability (±0.02 mm) required for PCB, connector, and component handling. Minimal particle generation suitable for semi-clean environments. Sensor-ready for closed-loop position verification.
4. Logistics & Palletizing
FR40–FR63 pneumatic parallel grippers handle cartons, totes, and packaged goods in high-speed palletizing lines. Self-locking module available for high-rack transfer applications where workpiece drop risk is unacceptable. Custom jaw geometry for irregular package shapes.
5. Automotive Manufacturing
High-cycle body panel handling, engine component tending, and sub-assembly transfer. FR series grippers are built for 2–3 shift continuous operation, with guide rails tested to multi-million cycle service life under realistic offset loading conditions.
6. Food & Pharmaceutical Handling
Food-safe aluminium alloy with anodized finish for corrosion resistance in washdown environments. IP67 sealing available on request. Gentle jaw closure speed adjustment via flow control valves for delicate or fragile product handling without surface damage.
