High Precision Industrial Robot Pneumatic Finger Gripper Link
Robust Durable Design for Automated Machine Tending Material Handling Assembly Applications
As a technician on the floor, I work with robotic arms and grippers every day. Today, let's talk about a core component we use that's proven incredibly reliable: the Pneumatic Finger Gripper Link. In simple terms, it's the part at the very end of the robot's arm, responsible for directly gripping and manipulating parts—essentially the "hand" of the robot.
This pneumatic finger gripper link is a workhorse on our automated production lines. Driven by compressed air, it's compact and has a very fast response time. We primarily use it to grip various shafts, flanges, and small housing components. Integrated onto 6-axis or SCARA robots, it enables precise machine tending and material handling.
Features
- High Rigidity Design: Manufactured from high-quality alloy steel with through-hardening treatment. We've been using it at high frequency for over half a year with zero deformation. Its durability is exceptional.
- High Repeatability: The dual-side timing belt drive ensures both fingers open and close with high-precision synchronisation. Every grip is in the exact same position, guaranteeing production consistency.
- Easy Installation & Maintenance: The body has multiple standard mounting holes, making interface with our existing robot flanges straightforward. The cylinder module is simplified; if we need to replace a seal, it's just a few screws away, minimising downtime.
- Strong Compatibility: Through-hole pneumatic ports with standard M5 quick-connect fittings plug directly into our solenoid valve manifolds, making pneumatic connections hassle-free.

Applications
This unit is a versatile tool. We mainly deploy it in the following scenarios:
- Machine Tending: Loading and unloading parts from CNC machining centers, boosting efficiency and safety.
- Component Transfer: Moving parts like engine blocks or bearing housings on assembly lines.
- Positioning & Assembly: Working with vision systems to precisely pick and place small components for press-fitting.
- Packaging & Palletizing: Gripping boxed or bagged products for stacking.
Customization
The standard model is great, but if you have unique workpieces—very heavy or odd-shaped—the manufacturer offers customization. Options include extended fingers, dust-proof seals, or special surface treatments (like nickel plating for corrosion resistance). We've inquired about these; the process is flexible.
Support and Services
The supplier's technical support is responsive. Whenever we have an issue, sending a drawing via email usually gets us a solution from their engineers quickly. Their spare parts inventory is also well-stocked. In urgent replacement scenarios, shipping is fast, helping to minimise our production stoppages.
