This model is discontinued
AirTAC has phased out the MTAL series. You can still order this code here: we ship the direct replacement MTBL25X30U, 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 MTAL25X30U
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X30U 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X30U.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X30U
The AirTAC MTAL25X30U is a discontinued single-acting pull-type mini cylinder with a 25mm bore and 30mm stroke. Air retracts the rod while an internal spring extends it, yielding a fail-safe extended home position. This U-version features a flat-end back cover and delivers a usable pull force of 137.2 N at 0.5 MPa.
The direct replacement is the MTBL25X30U, matching the bore, stroke, G1/8 port, and U-mounting. The MTAL uses threaded covers and a fixed rubber bumper, whereas the MTBL features a riveted rolling-packed body. Because this specific MTAL25X30U SKU lacks the -S magnet code, it cannot accept a position sensor. The MTBL upgrade also shifts sensor compatibility from the older CS1-M/DS1-M to the modern CMSG/DMSG/EMSG family.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X30U Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X30U |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X30U |
| 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X30U 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 MTAL25X30U Is Used
Injection Mold Ejection
Pulls a mold ejector pin back against a 137.2 N load at 0.5 MPa, ensuring the pin retracts safely before the mold closes.
Safety Guard Latch
Draws back a machine guard latch to allow access, using the spring-extended fail-safe to lock the guard securely when air is removed.
Tensioning Wire Guides
Maintains wire tension in a textile winding machine, pulling the guide arm with a 219.6 N force at 0.7 MPa to absorb slack.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X30U with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X30U
To replace this MTAL25X30U, select the MTBL25X30U. Confirm the 25mm bore, 30mm stroke, G1/8 PT port, M10x1.25 rod thread, flat-end U back cover, and the 0.2 MPa minimum operating pressure. Remember that the fail-safe home is extended, so apply no external load on the spring extend stroke. If you need less force, the neighbouring 20mm bore provides 81.7 N at 0.5 MPa. If you need more power, step up to the 32mm bore, which offers 261.2 N at 0.5 MPa.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X30U (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X30U instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X30U FAQ
Yes, the MTAL25X30U is discontinued. The direct replacement is the MTBL25X30U, which matches the 25mm bore, 30mm stroke, 137.2 N pull force at 0.5 MPa, G1/8 port, and flat-end U back cover. The MTBL upgrades the body to a riveted rolling-packed design and uses CMSG/DMSG/EMSG sensors if you add a magnet.
This single-acting pull cylinder provides a usable pull force of 137.2 N at 0.5 MPa and 219.6 N at 0.7 MPa. It requires a minimum of 0.2 MPa to retract the rod. On air loss, the internal spring pushes the rod to the extended fail-safe home position. Note that it cannot hold a mid-stroke load without an external locking device.
