SMC MHF2-8D Pneumatic Air Gripper Cylinder
1. Product Overview
The SMC MHF2-8D is a compact, parallel-style pneumatic air gripper from SMC’s MHF2 series, engineered for precision gripping and positioning of small workpieces in industrial automation systems. Featuring an 8 mm jaw stroke and double-acting operation, this gripper employs a built-in cam mechanism to drive two parallel jaws for synchronous opening and closing. Its ultra-thin, low-profile design (14 mm maximum thickness) makes it ideal for installation in space-constrained environments such as electronic component assembly, semiconductor handling, laboratory automation, and robotic end-effectors. The MHF2-8D delivers consistent gripping force and high positional accuracy, with compatibility for magnetic switches to enable real-time position feedback, ensuring reliable integration into automated production lines.
2. Main Functions
| Function | Detailed Description |
|---|---|
| Parallel Jaw Gripping | Dual parallel jaws driven by a precision cam mechanism ensure synchronous, balanced opening and closing, providing stable clamping of small workpieces without lateral displacement. |
| Double-Acting Bidirectional Operation | Uses compressed air for both gripping (jaw closing) and releasing (jaw opening) actions, eliminating the need for return springs and enabling adjustable gripping force via pressure regulation. |
| Precision Positioning | High-precision machining of the cam and jaw guide rails ensures repeatable jaw positioning accuracy, suitable for micro-component assembly and pick-and-place tasks with tight tolerances. |
| Magnetic Position Feedback | Integrated magnetic ring in the piston allows installation of magnetic proximity sensors, providing real-time signals for jaw open/closed status to support PLC-controlled sequence operations and safety interlocks. |
| Space-Saving Integration | Ultra-thin profile and centralized air port design enable direct mounting on robotic arms, linear slides, or compact fixtures, optimizing layout in dense automation setups. |
| Versatile Workpiece Compatibility | Adaptable to small cylindrical, rectangular, or irregularly shaped workpieces via customizable jaw pads, expanding application flexibility in precision manufacturing tasks. |
3. Technical Features
- Cam-Driven Synchronous Jaw Movement: The internal cam mechanism converts linear piston motion into precise parallel jaw displacement, ensuring zero jaw misalignment and consistent gripping force distribution.
- Ultra-Compact Low-Profile Design: With a maximum thickness of only 14 mm, the gripper fits into narrow installation spaces where standard grippers cannot be accommodated, reducing overall system footprint.
- Durable Corrosion-Resistant Construction: Main body and jaws made of hard-anodized aluminum alloy; piston rod and internal components crafted from SUS304 stainless steel for wear and corrosion resistance in industrial environments.
- Adjustable Gripping Force: Gripping force can be regulated between 10 N and 45 N (at 0.2–0.7 MPa operating pressure) via a pneumatic regulator, adapting to different workpiece hardness and size requirements.
- Broad Operating Conditions: Functions reliably at an air pressure range of 0.2–0.7 MPa and an ambient temperature range of -10°C to 60°C, compatible with filtered compressed air (particle size ≤5 μm).
- Sensor Integration Flexibility: Compatible with SMC D-M9 series magnetic switches, which can be mounted on the gripper’s side grooves without additional brackets, simplifying setup and maintenance.
- Maintenance-Free Operation: Sealed internal components and lubricated cam mechanism eliminate the need for regular lubrication, reducing downtime and operational costs.
