Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL32X25SCA
The AirTAC Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL32X25SCA is a genuine single acting, pull (spring extend) aluminum-barrel mini round cylinder with a Ø32mm bore and 25mm stroke, G1/8 air ports and a fixed rubber bumper. Air drives the pull (work) stroke and the spring returns the rod — it rests extended on air loss.

About the Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL32X25SCA
The AirTAC MTBL32X25SCA is a compact single-acting pull-type mini cylinder with a 32mm bore and 25mm stroke. Air retracts the rod while an internal spring extends it, yielding a fail-safe extended home position. It delivers 224.8 N of usable pull force at 0.5 MPa and uses a Ø12 mm hard-chrome carbon steel rod with an M10x1.25 thread.
This SKU includes a built-in magnet (-S) for CMSG reed or DMSG/EMSG electronic sensors, and a CA pivot/clevis back cover that swings on a pin to absorb arcing angular loads. It features a riveted rolling-packed aluminum barrel and a fixed rubber bumper, with overall length increasing by twice the stroke.
Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL32X25SCA Technical Specifications
| Model | Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL32X25SCA |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder |
| Bore size | Ø32 mm |
| Stroke | 25 mm |
| Acting type | Single acting, pull (spring extend) |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.2 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 50 – 800 mm/s |
| Cushion | Fixed rubber bumper |
| Max standard stroke | Up to 100 mm |
Single-acting minimum working pressure is 0.2 MPa (the air must overcome the return spring). Do not apply an external load during the spring return stroke. Thread options: PT / G / NPT.
Usable Pull Force (Ø32mm)
| Pressure | Pull force (net of spring) |
|---|---|
| 0.5 MPa | 224.8 N |
| 0.7 MPa | 363.0 N |
These are the usable single-acting forces after the return spring — lower than a same-bore double-acting MBL. Size with a margin.

Where the Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL32X25SCA Is Used
Packaging Flap Folding
Pulls cardboard carton flaps closed on a packaging line using its 224.8N @0.5MPa pull stroke, with the CA pivot absorbing mechanism misalignment.
PCB Test Socket Extraction
Draws a test fixture probe plate downward to seat connectors, relying on the -S magnet and DMSG sensor to verify the retracted pull position.
Textile Tensioning Arm
Tensions fabric web on a loom; the spring-extend fail-safe releases tension upward if air pressure drops, preventing material tearing.
Is the Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL32X25SCA the Right Cylinder?
For sizing, the MTBL32X25SCA provides 224.8 N pull force at 0.5 MPa. Step down to the 25mm bore (132.6 N @0.5 MPa) for lighter tensioning, or step up to the 40mm bore (339.1 N @0.5 MPa) for heavier drawing tasks. Unlike the MSBL push type, this MTBL fails safe extended on air loss. It requires a 3/2 valve and at least 0.2 MPa pressure to overcome the return spring.
Never apply external load to the spring-extend return stroke. The CA clevis mount handles pivoting loads, unlike the rigid U flat-end. To replace, match the 32mm bore, 25mm stroke, G1/8 PT port, CA back cover, and -S magnet. At 25mm stroke, side-load bending is minimal, but ensure the clevis pin is aligned to prevent rod binding.
Quick checklist
- ✓ Usable pull force at your pressure (min 0.2 MPa)
- ✓ Fail-safe rest position (extended)
- ✓ No external load on the spring return stroke
- ✓ Magnet (S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.2 – 1.0 MPa (min 0.2 to overcome the spring).
- check Apply no external load on the spring return stroke.
- check Avoid side load on the piston rod.
- check Use the correct mounting accessory (LB / FA / SDB) and back cover (CA / U).
- check Installation by qualified personnel per AirTAC docs.
Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL32X25SCA FAQ
The MTBL32X25SCA generates 224.8 N pull force at 0.5 MPa and 363 N at 0.7 MPa. It requires a minimum operating pressure of 0.2 MPa to overcome the internal return spring and retract the rod.
Air retracts the rod for the work stroke, but the internal spring extends it back out on air loss, creating a fail-safe extended home. The built-in -S magnet allows CMSG reed or DMSG/EMSG electronic switches to detect this rod position.
