This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X20U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X20U 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 MTAL25X20U
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X20U is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø25mm bore and 20mm 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X20U.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X20U
The AirTAC MTAL25X20U is a discontinued single-acting pull-type mini cylinder with a 20 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 MTBL25X20U, matching the bore, stroke, and flat-end U cover.
This 25 mm bore unit features a G1/8 port, a 10 mm rod, and an M10x1.25 rod-end thread. It uses a fixed rubber bumper for end-of-stroke damping. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor. The MTBL upgrade switches from threaded covers to a riveted rolling-packed body and updates the sensor family from CS1-M/DS1-M to CMSG/DMSG/EMSG.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X20U Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X20U |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X20U |
| Bore size | Ø25 mm |
| Stroke | 20 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X20U 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 MTAL25X20U Is Used
Packaging Flap Control
Pulls a cardboard flap guide on a carton erecting machine. The 137.2 N pull at 0.5 MPa handles the tension, while the spring-extended fail-safe clears the path when air drops.
Textile Latch Release
Retracts a yarn tension latch on a weaving loom. Air retracts the 10 mm rod for the pull stroke, and the spring safely extends it out of the way during a power loss.
Small Part Draw-back
Draws back a tiny electronic component stop on a PCB conveyor. The 20 mm stroke provides precise retraction without overtraveling the assembly.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X20U with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X20U
To replace your MTAL25X20U, use the MTBL25X20U as a direct drop-in. Confirm the 25 mm bore, 20 mm stroke, G1/8 port, PT thread, and flat-end U back cover. Remember the minimum operating pressure is 0.2 MPa, and never apply external load on the spring extend stroke. On air loss, the fail-safe home is extended.
If you need to step sizes, consider the 20 mm bore neighbor, which provides 81.7 N of pull force at 0.5 MPa, or the 32 mm bore neighbor, which provides 261.2 N at 0.5 MPa. The 25 mm bore itself yields 219.6 N at 0.7 MPa. Since the stroke is under 100 mm, side-load and rod-bending risks are minimal.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X20U (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X20U instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X20U FAQ
Yes, the MTAL25X20U is discontinued. The exact drop-in replacement is the MTBL25X20U, which matches the 25 mm bore, 20 mm stroke, G1/8 port, and flat-end U cover. The MTBL upgrades the body to a riveted rolling-packed design.
The usable pull force is 137.2 N at 0.5 MPa and 219.6 N at 0.7 MPa. Because this SKU lacks the -S magnet, it cannot take a position sensor. The MTBL replacement with a magnet uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M.
