This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X50U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X50U 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 MTAL25X50U
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X50U is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø25mm bore and 50mm 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X50U.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X50U
The AirTAC MTAL25X50U is a discontinued single-acting pull-type mini cylinder with a 25 mm bore and 50 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. The exact drop-in replacement is the MTBL25X50U, which matches the bore, stroke, G1/8 port, and U back cover.
This U-cover SKU lacks the -S magnet option, so it cannot accept a position sensor. The original MTAL features threaded covers, whereas the MTBL replacement uses a riveted rolling-packed body. Both use a fixed rubber bumper for end-of-stroke damping. Remember that the fail-safe home position is extended, and you must apply no external load on the spring-extend stroke.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X50U Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X50U |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X50U |
| Bore size | Ø25 mm |
| Stroke | 50 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X50U 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 MTAL25X50U Is Used
Packaging Film Tensioning
Pulls a web-tensioning idler roller back during the air retract stroke, providing 137.2 N of pull at 0.5 MPa to keep packaging film taut without powered holding.
Gate Latch Retraction
Retracts a security gate latch on a 50 mm stroke to allow access, using the spring-extend fail-safe to positively lock the latch back out when air is removed.
Textile Gripper Open
Pulls a textile fabric gripper closed against the spring, ensuring the jaws spring open to release the material safely if the 0.2 MPa minimum air pressure drops.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X50U with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X50U
To replace this MTAL25X50U, install the MTBL25X50U. Confirm the 25 mm bore, 50 mm stroke, G1/8 PT port, M10x1.25 rod thread, and the flat-end U back cover. Because this SKU has no -S magnet, it cannot take a sensor. The MTBL upgrade also changes the switch family from CS1-M/DS1-M to CMSG/DMSG/EMSG if you ever add one. Maintain a minimum 0.2 MPa operating pressure to overcome the return spring.
For sizing, step down to the 20 mm bore if you need less force (81.7 N at 0.5 MPa), or step up to the 32 mm bore if you need more (261.2 N at 0.5 MPa). The spring extends the rod on air loss, so use an external lock if you must hold a suspended load.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X50U (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X50U instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X50U FAQ
Yes, the MTAL25X50U is discontinued. The exact drop-in replacement is the MTBL25X50U, matching the 25 mm bore, 50 mm stroke, G1/8 port, and U back cover. The MTBL upgrades the body to a riveted rolling-packed design and changes the sensor family from CS1-M/DS1-M to CMSG/DMSG/EMSG.
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 fail-safe home position is extended, meaning the internal spring pushes the rod out on air loss. It requires a minimum of 0.2 MPa to operate, and the fixed rubber bumper absorbs end-of-stroke impact.
