This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X25CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X25CA 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 MTAL20X25CA
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X25CA is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø20mm bore and 25mm 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X25CA.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X25CA
The AirTAC MTAL20X25CA 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. This 20mm bore provides a usable pull force of 81.7 N at 0.5 MPa. The direct drop-in replacement is the MTBL20X25CA, matching the bore, 25mm stroke, G1/8 port, and CA mounting.
This SKU features a CA pivot clevis back cover that swings on a pin to absorb arcing loads. Because it lacks the -S suffix, this cylinder cannot accept a position sensor. The legacy MTAL uses threaded covers and CS1-M/DS1-M switches, whereas the MTBL upgrade features a riveted rolling-packed body and CMSG/DMSG/EMSG sensors. End-of-stroke damping relies on a fixed rubber bumper.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X25CA Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X25CA |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X25CA |
| Bore size | Ø20 mm |
| Stroke | 25 mm |
| Acting type | Single acting, pull (spring extend) |
| Port size | G1/8 |
| Rod thread | M8×1.25 |
| 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X25CA carries the same single-acting ratings.
Usable Pull Force (Ø20mm)
| Pressure | Pull force (net of spring) |
|---|---|
| 0.5 MPa | 81.7 N |
| 0.7 MPa | 134.4 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 MTAL20X25CA Is Used
Packaging Flap Pull-in
Retracts a carton sealing arm via the 81.7 N pull force at 0.5 MPa, using the spring-extend fail-safe to safely open the arm during an air loss event.
Textile Tension Release
Draws back a fabric tensioning pin on a loom; the CA clevis accommodates slight misalignment while the spring safely extends the pin when air is cut.
Electronic Tester Disconnect
Pulls a spring-loaded test probe away from a PCB; the 25mm stroke provides precise withdrawal without powered mid-stroke holding.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X25CA with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X25CA
To replace this MTAL20X25CA with the MTBL20X25CA, confirm the 20mm bore, 25mm stroke, PT G1/8 port, M8x1.25 rod thread, and CA pivot clevis. Remember the 0.2 MPa minimum operating pressure and apply no external load on the spring-extend stroke. On air loss, the spring forces the rod out to the extended fail-safe home.
If sizing up or down, the neighbouring 25mm bore yields 137.2 N at 0.5 MPa. As the 20mm is the smallest available, stepping down requires a non-standard solution. The fixed rubber bumper absorbs end impacts without adjustable cushioning.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X25CA (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X25CA instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X25CA FAQ
Yes, the MTAL20X25CA is discontinued. The exact drop-in replacement is the MTBL20X25CA, which matches the 20mm bore, 25mm stroke, G1/8 port, and CA clevis. You will need CMSG/DMSG/EMSG sensors for the MTBL if you upgrade from an -S MTAL, though this specific no-magnet SKU cannot take a sensor.
This single-acting pull cylinder provides a usable pull force of 81.7 N at 0.5 MPa and 134.4 N at 0.7 MPa (maximum 13.7 kgf). It operates between 0.2 and 1.0 MPa, with speeds of 50-800 mm/s. Remember that on air loss, the internal spring pushes the rod to the extended fail-safe position.
