This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X25SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X25SU in place of this model. The replacement upgrades to a riveted rolling-packed body and CMSG / DMSG / EMSG sensors (the MAL used CS1-M / DS1-M).
Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X25SU
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X25SU is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø40mm bore and 25mm stroke, G1/4 ports and a fixed rubber bumper. Air drives the pull (work) stroke and the spring returns the rod — it rests extended on air loss. This model is discontinued; the drop-in replacement is the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X25SU.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X25SU
The AirTAC MTAL40X25SU is a discontinued single-acting pull-type mini cylinder with a 40mm bore and 25mm stroke. Air retracts the rod while an internal spring extends it, providing a fail-safe extended home position. It delivers a usable pull force of 439.4 N at 0.5 MPa. The exact drop-in replacement is the MTBL40X25SU, matching the bore, stroke, G1/4 port, and U back cover.
This SKU includes the -S magnet for position sensing, originally paired with CS1-M or DS1-M switches. The MTBL40X25SU upgrade shifts to CMSG, DMSG, or EMSG sensors and features a riveted rolling-packed body instead of the MTAL's threaded covers. The fixed rubber bumper absorbs end-of-stroke impact, and operators must apply no external load on the spring extend stroke.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X25SU Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X25SU |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X25SU |
| Bore size | Ø40 mm |
| Stroke | 25 mm |
| Acting type | Single acting, pull (spring extend) |
| Port size | G1/4 |
| Rod thread | M12×1.25 |
| 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. The AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X25SU carries the same single-acting ratings.
Usable Pull Force (Ø40mm)
| Pressure | Pull force (net of spring) |
|---|---|
| 0.5 MPa | 439.4 N |
| 0.7 MPa | 650.4 N |
Usable single-acting force after the return spring — lower than a same-bore double-acting cylinder. Size with a margin.

Where the Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X25SU Is Used
Injection Mold Ejection
Pulls a mold ejection pin back 25mm against 439.4 N at 0.5 MPa, ensuring the pin clears the cavity during mold closing.
Packaging Flap Tensioning
Draws back a cardboard flap guide on a carton erector, using the spring-extended fail-safe to park the guide out of the way.
Pneumatic Gripper Close
Retracts a 40mm bore gripper jaw to clamp heavy cast parts, relying on the robust 650.4 N pull force at 0.7 MPa.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X25SU with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X25SU
To replace the MTAL40X25SU with the MTBL40X25SU, verify the 40mm bore, 25mm stroke, G1/4 port, PT thread, U flat-end back cover, and -S magnet. Note the sensor family change from CS1-M/DS1-M to CMSG/DMSG/EMSG. Maintain the 0.2 MPa minimum operating pressure and remember the fail-safe home is extended.
For sizing both ways, step down to the 32mm bore (261.2 N pull at 0.5 MPa) for lighter tension tasks, or step up if higher force is needed. The 40mm bore provides 439.4 N at 0.5 MPa and 650.4 N at 0.7 MPa. At 25mm stroke, side-load risks are minimal, but always avoid external loading on the extend stroke.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X25SU (same bore/stroke/force)
- ✓ Same pull direction and extended fail-safe home
- ✓ Min 0.2 MPa; no external load on the spring return
- ✓ Sensor: swap CS1-M/DS1-M → CMSG/DMSG/EMSG
- ✓ Confirm back cover (CA / U) and thread (PT/NPT/G)
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 Front/rear covers are threaded — not for field disassembly.
- check For new builds, specify the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X25SU instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X25SU FAQ
Yes, the MTAL40X25SU is discontinued. The exact drop-in replacement is the MTBL40X25SU, matching the 40mm bore, 25mm stroke, G1/4 port, and U back cover. You will need to update your sensors, as the MTAL -S magnet used CS1-M/DS1-M switches, while the MTBL uses CMSG/DMSG/EMSG switches.
It is a single-acting pull cylinder where air retracts the rod and a spring extends it. The fail-safe home position is extended. The usable pull force is 439.4 N at 0.5 MPa and 650.4 N at 0.7 MPa. It requires a minimum operating pressure of 0.2 MPa to overcome the internal spring.
