This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X80U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X80U 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 MTAL20X80U
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X80U 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 drop-in replacement is the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X80U.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X80U
The AirTAC MTAL20X80U is a discontinued single-acting pull-type mini cylinder with an 80 mm stroke. Air retracts the rod, and an internal spring extends it. The exact drop-in replacement is the MTBL20X80U, matching the 20 mm bore, stroke, and G1/8 port.
This 20 mm bore delivers a usable pull force of 81.7 N at 0.5 MPa and 134.4 N at 0.7 MPa. It features a fixed rubber bumper and threaded covers, whereas the MTBL upgrade uses a riveted body. This U-flat-end SKU has no -S magnet, so it cannot take a CS1-M or DS1-M position sensor. The fail-safe home is extended.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X80U Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X80U |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X80U |
| 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X80U 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 MTAL20X80U Is Used
Textile Loom Tensioning
Pulls a thread guide back on this 80 mm stroke to maintain warp tension, using 81.7 N at 0.5 MPa.
Gate Valve Actuation
Retracts a small diverting gate in a packaging machine, relying on the spring-extended fail-safe to clear the path on air loss.
PCB Tester Probe
Draws back a spring-loaded test probe from a fixture, ensuring the pin retracts out of the board when pressure drops.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X80U with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X80U
Replace this MTAL20X80U with the MTBL20X80U. Confirm the 20 mm bore, 80 mm stroke, G1/8 port, PT thread, and U flat-end back cover. Because this SKU lacks the -S magnet, it cannot accept a position sensor; the MTBL upgrade uses CMSG/DMSG/EMSG switches. Maintain the 0.2 MPa minimum operating pressure and apply no external load on the spring-extend stroke. To size up, the 25 mm bore offers 137.2 N at 0.5 MPa; to size down, no smaller standard MTAL bore exists.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X80U (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X80U instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X80U FAQ
Yes, the MTAL20X80U is discontinued. The exact drop-in replacement is the MTBL20X80U, which matches the 20 mm bore, 80 mm stroke, U flat-end cover, and G1/8 port. The MTBL uses a riveted rolling-packed body instead of threaded covers.
The usable pull force is 81.7 N at 0.5 MPa and 134.4 N at 0.7 MPa. The operating pressure is 0.2-1.0 MPa, with a 0.2 MPa minimum. The fail-safe home is extended, and speed ranges from 50-800 mm/s.
