This model is discontinued
AirTAC has phased out the MTAL series. You can still order this code here: we ship the direct replacement MTBL20X80SCA, 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 MTAL20X80SCA
The AirTAC MTAL Rear Single Acting Mini Cylinder MTAL20X80SCA 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X80SCA.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X80SCA
The AirTAC MTAL20X80SCA is a discontinued 20mm mini single-acting pull cylinder. Air retracts the rod while an internal spring extends it, yielding a fail-safe EXTENDED home position. It delivers 81.7 N of usable pull force at 0.5 MPa and uses a G1/8 port with an M8x1.25 rod thread.
The direct replacement is the MTBL20X80SCA, matching bore, stroke, and force. The MTAL uses threaded covers and a CS1-M / DS1-M magnet sensor, whereas the MTBL upgrades to a riveted rolling-packed body and CMSG / DMSG / EMSG switches. The CA back cover provides a pivot clevis for arcing loads, and end-of-stroke damping relies on a fixed rubber bumper.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X80SCA Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X80SCA |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X80SCA |
| 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X80SCA 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 MTAL20X80SCA Is Used
Packaging Flap Folder
Retracts a folding arm to tuck cardboard box flaps on a packaging line, using 81.7 N pull at 0.5 MPa, while the spring-extend safely parks the arm out of the way.
Textile Tension Gate
Draws back a tensioning pin on a weaving loom; the CA pivot clevis accommodates slight arcing motion as the fabric feeds through the machine.
Electronic Component Sorter
Pulls a diverter gate to route PCBs on an SMT conveyor, relying on the fail-safe extended position to keep the default lane open during air loss.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X80SCA with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X80SCA
To replace the MTAL20X80SCA, order the MTBL20X80SCA. Confirm the 20mm bore, 80mm stroke, G1/8 port, PT thread, CA pivot back cover, and the -S magnet (requiring a sensor swap from CS1-M/DS1-M to CMSG/DMSG/EMSG). Maintain the 0.2 MPa minimum operating pressure and apply NO external load on the spring-extend stroke, as the fail-safe home is EXTENDED.
For sizing flexibility, stepping down is not an option below 20mm. Stepping up to the 32mm bore raises the 0.5 MPa pull force to 261.2 N if your application needs more retract strength. At 80mm stroke, watch for side loads that could bend the 8mm rod.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X80SCA (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X80SCA instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X80SCA FAQ
Yes, the MTAL20X80SCA is discontinued. The direct replacement is the MTBL20X80SCA, matching the 20mm bore, 80mm stroke, CA cover, and force. You must swap the CS1-M / DS1-M sensors for CMSG / DMSG / EMSG switches.
It is a single-acting pull cylinder (air retracts, spring extends) with a fail-safe extended home. Usable pull force is 81.7 N at 0.5 MPa and 134.4 N at 0.7 MPa (max 13.7 kgf). Operating pressure is 0.2-1.0 MPa, speed is 50-800 mm/s, and it uses a fixed rubber bumper.
