This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X40U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X40U 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 MTAL25X40U
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X40U 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X40U.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X40U
The AirTAC MTAL25X40U is a discontinued single-acting pull-type mini cylinder with a 25 mm bore and 40 mm stroke. Air retracts the rod to perform work, while an internal spring extends it back out. It delivers a usable pull force of 137.2 N at 0.5 MPa (219.6 N at 0.7 MPa). The exact drop-in replacement is the MTBL25X40U, matching the bore, stroke, G1/8 port, and U flat-end back cover.
This U-cover SKU lacks the -S magnet option, so it cannot accept CS1-M or DS1-M position sensors. The MTAL features threaded covers and a fixed rubber bumper, whereas the MTBL upgrade uses a riveted rolling-packed body. Operating pressure is 0.2-1.0 MPa. Apply no external load on the spring-extend stroke to avoid damaging the internal return mechanism.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X40U Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X40U |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X40U |
| 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X40U 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 MTAL25X40U Is Used
Electronic Connector Unlatching
Pulls a spring-loaded latch back 40 mm to release electronic connector housings on an assembly line, using 137.2 N of pull at 0.5 MPa to overcome the latch friction.
Packaging Film Tensioning
Retracts a tensioning idler on a vertical form-fill-seal machine to draw back the film web; the spring-extend fail-safe safely releases tension during an E-stop.
Textile Spindle Draw-Back
Pulls a small textile spinning spindle out of the drive engagement zone, relying on the 25 mm bore's 219.6 N force at 0.7 MPa for reliable retraction under residual drag.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X40U with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X40U
To replace the MTAL25X40U, select the MTBL25X40U. Confirm the 25 mm bore, 40 mm stroke, G1/8 port, PT thread, and U flat-end back cover. Because this SKU has no -S magnet, it cannot take a sensor; if you need position detection, step up to an MTBL -S model and use CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M. Remember the 0.2 MPa minimum operating pressure and that the fail-safe home is EXTENDED.
For sizing flexibility, stepping down to the 20 mm bore yields 81.7 N of pull at 0.5 MPa, while stepping up to the 32 mm bore provides 261.2 N at 0.5 MPa. The fixed rubber bumper absorbs end-of-stroke impact without adjustable cushioning. On air loss, the spring extends the rod as a rest, not a lock; use an external holding device for suspended loads.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X40U (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X40U instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X40U FAQ
Yes, the MTAL25X40U is discontinued. The exact drop-in replacement is the MTBL25X40U, which matches the 25 mm bore, 40 mm stroke, G1/8 port, and U flat-end back cover. The MTBL upgrades the construction to a riveted rolling-packed body.
The usable pull force is 137.2 N at 0.5 MPa and 219.6 N at 0.7 MPa, with a minimum operating pressure of 0.2 MPa. It is a single-acting pull cylinder: air retracts the rod, and the fail-safe home position is EXTENDED via an internal spring. This SKU has no -S magnet and cannot accept a position sensor.
