This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X25U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X25U 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 MTAL40X25U
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X25U 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X25U.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X25U
The AirTAC MTAL40X25U is a discontinued single-acting pull mini cylinder with a 40mm bore and 25mm stroke. Air retracts the rod while an internal spring extends it. The exact drop-in replacement is the MTBL40X25U, matching the G1/4 port, M12x1.25 rod thread, and U back cover. This 40mm bore yields a usable pull force of 439.4 N at 0.5 MPa.
The MTAL40X25U uses a PT tapered port thread and a fixed rubber bumper. It lacks a magnet, so it cannot accept a position sensor. The MTBL upgrade replaces the older threaded covers with a riveted rolling-packed body. Remember that the fail-safe home is extended, and you must apply no external load on the spring extend stroke.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X25U Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X25U |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X25U |
| 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X25U 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 MTAL40X25U Is Used
Injection Mold Ejection
Pulls an injection mold ejector pin back against the mold base with 439.4 N at 0.5 MPa, using the spring to safely extend and reset the pin on air loss.
Packaging Flap Closing
Retracts to pull a packaging carton flap closed during case erecting, relying on the fail-safe extended position to release the carton if compressed air drops.
Press Brake Guard Retract
Draws back a light press brake safety guard during the downstroke, with the internal spring pushing the guard back out to protect the operator when air is removed.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X25U with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X25U
To replace the MTAL40X25U, order the MTBL40X25U. Confirm the 40mm bore, 25mm stroke, G1/4 port, PT thread, and U flat-end back cover. Because this SKU lacks the -S magnet, it cannot take a sensor; the MTBL upgrade would require CMSG, DMSG, or EMSG switches on an -S model. Minimum working pressure is 0.2 MPa.
The fail-safe home is extended, and no external load is allowed on the spring extend stroke. If you need less force, step down to the 32mm bore (261.2 N at 0.5 MPa). As the largest standard size, there is no larger bore to step up to in this mini series.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X25U (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X25U instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X25U FAQ
Yes, the MTAL40X25U is discontinued. The exact drop-in replacement is the MTBL40X25U. It matches the 40mm bore, 25mm stroke, 439.4 N pull force at 0.5 MPa, G1/4 port, and U back cover. The MTBL upgrade changes the threaded covers to a riveted rolling-packed body.
The usable pull force is 439.4 N at 0.5 MPa and 650.4 N at 0.7 MPa. The fail-safe home is extended. On air loss, the internal spring pushes the rod back out. You must apply no external load on the spring extend stroke, and a minimum of 0.2 MPa air pressure is required for operation.
