This model is discontinued
AirTAC has phased out the MTAL series. You can still order this code here: we ship the direct replacement MTBL20X30SU, 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 MTAL20X30SU
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X30SU is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø20mm bore and 30mm 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30SU.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X30SU
The AirTAC MTAL20X30SU is a discontinued single-acting pull-type mini cylinder with a 20mm bore and 30mm stroke. Air retracts the rod, while an internal spring extends it. It provides a usable pull force of 81.7 N at 0.5 MPa. The direct replacement is the MTBL20X30SU.
This MTAL features threaded covers and a U flat-end back cover. The -S magnet supports older CS1-M or DS1-M switches, whereas the MTBL replacement uses CMSG, DMSG, or EMSG sensors with a riveted rolling-packed body. It uses a fixed rubber bumper and a self-lubricating front-cover guide. Never apply external load on the spring extend stroke.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X30SU Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X30SU |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30SU |
| Bore size | Ø20 mm |
| Stroke | 30 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30SU 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 MTAL20X30SU Is Used
Thermoformer Film Tension
Pulls a plastic film carrier back against a stop using 81.7 N at 0.5 MPa. The spring-extend fail-safe safely releases web tension during an air loss shutdown.
Packaging Flap Latch
Retracts a mechanical latch pin to release carton flaps. The 20mm bore fits tight machine frames, and the spring-extend design parks the pin safely outboard.
Textile Gripper Draw-Back
Pulls a fabric gripper open against spring pressure. Air retracts the 8mm rod to release material, and the fail-safe extended state holds the grip when air drops.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X30SU with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30SU
To replace this MTAL20X30SU, use the MTBL20X30SU. Confirm the 20mm bore, 30mm stroke, G1/8 PT port, M8x1.25 rod thread, U back cover, and the sensor family change from CS1-M/DS1-M to CMSG/DMSG/EMSG. The minimum working pressure is 0.2 MPa, and the fail-safe home is extended.
If sizing up, the 25mm bore gives 137.2 N at 0.5 MPa. If sizing down, no smaller standard bore exists in this series. For any stroke at or over 100mm, watch for rod-bending side loads.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30SU (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30SU instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X30SU FAQ
Yes, the MTAL20X30SU is discontinued. The direct replacement is the MTBL20X30SU, which matches the 20mm bore, 30mm stroke, G1/8 port, and U back cover. The MTBL upgrades the body to a riveted rolling-packed design and uses CMSG, DMSG, or EMSG sensors instead of the older CS1-M or DS1-M switches.
The usable pull force is 2.6 N at 0.2 MPa, 81.7 N at 0.5 MPa, and 134.4 N at 0.7 MPa. The operating pressure range is 0.2-1.0 MPa, with a proof pressure of 1.5 MPa. It runs at 50-800 mm/s, uses a fixed rubber bumper, and the fail-safe home position is fully extended.
