This model is discontinued
AirTAC has phased out the MTAL series. You can still order this code here: we ship the direct replacement MTBL20X80SU, 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 MTAL20X80SU
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X80SU is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø20mm bore and 80mm 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X80SU.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X80SU
The AirTAC MTAL20X80SU is a discontinued single-acting pull-type mini cylinder with an 80 mm stroke. Air retracts the rod, while an internal spring extends it. The direct replacement is the MTBL20X80SU, matching the 20 mm bore, G1/8 port, and U back cover. This bore yields a usable pull force of 81.7 N at 0.5 MPa.
The -S magnet on this MTAL works with CS1-M / DS1-M switches; the MTBL replacement upgrades to CMSG / DMSG / EMSG sensors. This MTAL features threaded covers, whereas the MTBL uses a riveted rolling-packed body. End-of-stroke damping relies on a fixed rubber bumper. The fail-safe home is extended, meaning air loss pushes the rod out.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X80SU Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X80SU |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X80SU |
| Bore size | Ø20 mm |
| Stroke | 80 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X80SU 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 MTAL20X80SU Is Used
Thermoformer Film Draw
Pulls the heated plastic sheet taut over the mold using the 81.7 N force at 0.5 MPa, releasing to spring-extend when air cuts.
PCB Test Fixture Latch
Retracts an 8 mm rod to lock the test bed closed, relying on the CS1-M / DS1-M magnet for position feedback.
Textile Loom Tension Arm
Draws back the thread guide during yarn changes; the spring-extended fail-safe clears the mechanism for maintenance.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X80SU with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X80SU
Replace this MTAL20X80SU with the MTBL20X80SU. Confirm the 20 mm bore, 80 mm stroke, G1/8 port, PT thread, U flat-end back cover, and the magnet sensor family change (CS1-M / DS1-M to CMSG / DMSG / EMSG). Maintain the 0.2 MPa minimum working pressure. The fail-safe home is extended, and you must apply no external load on the spring extend stroke.
To size either direction: stepping down is not an option as 20 mm is the smallest bore. Stepping up to the 32 mm bore increases the 0.5 MPa usable pull force to 261.2 N. At 80 mm stroke, mind rod side-loads to prevent bending the 8 mm rod.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X80SU (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X80SU instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X80SU FAQ
Yes, the MTAL20X80SU is discontinued. The direct replacement is the MTBL20X80SU, matching the 20 mm bore, 80 mm stroke, G1/8 port, and U back cover. The MTBL upgrades the -S magnet to CMSG / DMSG / EMSG sensors and uses a riveted body instead of threaded covers.
It is a single-acting pull cylinder with a usable pull force of 81.7 N at 0.5 MPa and 134.4 N at 0.7 MPa (max 13.7 kgf). The minimum working pressure is 0.2 MPa. The fail-safe home is extended: on air loss, the internal spring pushes the rod out.
