This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X40SCM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X40SCM 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 MTAL25X40SCM
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X40SCM is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø25mm bore and 40mm stroke, G1/8 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X40SCM.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X40SCM
The AirTAC MTAL25X40SCM is a discontinued single-acting pull-type mini cylinder with a 25 mm bore and 40 mm stroke. Air retracts the rod while an internal spring extends it, yielding a fail-safe extended home position. It delivers a usable pull force of 137.2 N at 0.5 MPa. The exact drop-in replacement is the MTBL25X40SCM, matching the bore, stroke, G1/8 port, and CM mounting.
This S-suffix SKU includes a magnet for position sensing. The legacy MTAL uses CS1-M or DS1-M reed switches, whereas the MTBL upgrade uses CMSG, DMSG, or EMSG sensors. The MTAL features threaded covers and a fixed rubber bumper, while the newer MTBL uses a riveted rolling-packed body. Never apply external loads to the unpowered spring-extend stroke.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X40SCM Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X40SCM |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X40SCM |
| Bore size | Ø25 mm |
| Stroke | 40 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. The AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X40SCM carries the same single-acting ratings.
Usable Pull Force (Ø25mm)
| Pressure | Pull force (net of spring) |
|---|---|
| 0.5 MPa | 137.2 N |
| 0.7 MPa | 219.6 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 MTAL25X40SCM Is Used
Packaging Film Tensioning
Draws back a web-guide roller on a vertical form-fill-seal machine with 137.2 N at 0.5 MPa, releasing the film cleanly when air is cut.
Injection Mold Gate Puller
Retracts a sprue puller pin on a 40 mm stroke to extract cold runners from an injection molding tool, relying on the spring to park the pin out of the mold.
Lathe Chuck Safety Release
Pulls a secondary latch on an automated CNC lathe door; the spring-extend fail-safe ensures the latch clears the chuck area during an air loss event.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X40SCM with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X40SCM
To replace this MTAL25X40SCM, install the MTBL25X40SCM. Confirm the 25 mm bore, 40 mm stroke, PT G1/8 port, M10x1.25 rod thread, CM round-end cover, and the sensor family change from CS1-M/DS1-M to CMSG/DMSG/EMSG. The system requires a minimum 0.2 MPa pressure to overcome the return spring, and the fail-safe home is extended.
For sizing flexibility, stepping down to the 20 mm bore drops the 0.5 MPa pull force to 81.7 N. Stepping up to the 32 mm bore increases the 0.5 MPa pull force to 261.2 N. At 40 mm stroke, rod buckling is a minimal concern, but always avoid side loads.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X40SCM (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X40SCM instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X40SCM FAQ
Yes, the MTAL25X40SCM is discontinued. The exact drop-in replacement is the MTBL25X40SCM, which matches the 25 mm bore, 40 mm stroke, G1/8 port, and CM cover. You will need to upgrade your position sensors from the old CS1-M/DS1-M series to the CMSG/DMSG/EMSG series.
It is a single-acting pull cylinder with a usable pull force of 137.2 N at 0.5 MPa and 219.6 N at 0.7 MPa. The maximum theoretical force based on bore is roughly 246 kgf at 1.0 MPa, but actual usable pull is lower due to the opposing spring. It operates on 0.2-1.0 MPa pressure with a speed range of 50-800 mm/s.
