This model is discontinued
AirTAC has phased out the MTAL series. You can still order this code here: we ship the direct replacement MTBL25X30SU, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 MTAL25X30SU
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X30SU is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø25mm bore and 30mm 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 direct replacement is the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X30SU.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X30SU
The AirTAC MTAL25X30SU is a discontinued single-acting pull-type mini cylinder. Air retracts the rod, while an internal spring extends it, meaning the fail-safe home position is extended. At 25mm bore, this SKU delivers a usable pull force of 137.2 N at 0.5 MPa. The direct replacement is the MTBL25X30SU, matching the 30mm stroke, G1/8 port, and U back cover.
This -S variant includes a magnet for position sensing, originally using CS1-M or DS1-M switches; the MTBL successor upgrades to CMSG, DMSG, or EMSG sensors. The legacy MTAL features threaded covers and a fixed rubber bumper, whereas the current MTBL uses a riveted rolling-packed body. Remember that the return spring only provides passive extension, so apply no external load on the extend stroke.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X30SU Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X30SU |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X30SU |
| Bore size | Ø25 mm |
| Stroke | 30 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X30SU 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 MTAL25X30SU 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 tension instantly when air is removed.
Lathe Chuck Unlatching
Retracts a safety latch pin on a CNC lathe door; the spring-extended fail-safe keeps the pin locked out during an air loss event.
Textile Creel Release
Pulls a yarn-tensioning deflector out of the thread path on a winding machine, relying on the 30mm stroke to clear the fiber path.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X30SU with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X30SU
To replace the MTAL25X30SU, specify the MTBL25X30SU to match the 25mm bore, 30mm stroke, G1/8 PT port, M10x1.25 rod thread, U flat-end back cover, and magnet. The MTBL uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M. Both require a 3/2 valve and a minimum 0.2 MPa operating pressure. The fail-safe home remains extended.
If sizing your pull force, this 25mm bore gives 137.2 N at 0.5 MPa. Stepping down to the 20mm bore drops the pull to 81.7 N at 0.5 MPa, while stepping up to the 32mm bore increases it to 261.2 N at 0.5 MPa. The fixed rubber bumper absorbs end-of-stroke impact without adjustable cushioning.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X30SU (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X30SU instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X30SU FAQ
Yes, the MTAL25X30SU is discontinued. The direct replacement is the MTBL25X30SU, which matches the 25mm bore, 30mm stroke, G1/8 port, and U back cover. You must upgrade your position sensors from the old CS1-M/DS1-M to the new CMSG/DMSG/EMSG family.
It is a single-acting pull cylinder, so air retracts the rod and a spring extends it. The fail-safe home position is extended. The usable pull force is 137.2 N at 0.5 MPa and 219.6 N at 0.7 MPa, requiring a minimum of 0.2 MPa to operate.
