This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X20SCM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X20SCM 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 MTAL20X20SCM
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X20SCM is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø20mm bore and 20mm 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X20SCM.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X20SCM
The AirTAC MTAL20X20SCM is a discontinued single-acting pull, spring-extend mini cylinder. Air retracts the rod, while an internal spring extends it, yielding a fail-safe extended home position. It delivers a usable pull force of 81.7 N at 0.5 MPa and requires a minimum 0.2 MPa operating pressure.
The exact drop-in replacement is the MTBL20X20SCM, matching the 20 mm bore, 20 mm stroke, G1/8 port, and CM mounting. This MTAL features a CS1-M/DS1-M compatible magnet and threaded covers, whereas the MTBL upgrades to CMSG/DMSG/EMSG sensors and a riveted rolling-packed body. A fixed rubber bumper absorbs end-of-stroke impact.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X20SCM Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X20SCM |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X20SCM |
| Bore size | Ø20 mm |
| Stroke | 20 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X20SCM 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 MTAL20X20SCM Is Used
Electronic Component Test Handler
Pulls a delicate testing probe arm back to a safe home position. The 81.7 N pull force at 0.5 MPa is ideal for precise retraction, and the spring-extend fail-safe ensures the probe clears the workspace on air loss.
PCB Conveyor Gate Latch
Retracts a latch pin to release a downstream conveyor gate. The 20 mm stroke provides just enough movement, while the fail-safe extended position mechanically locks the gate during an emergency air shutdown.
Small Part Ejector Mechanism
Draws back an ejection finger inside a compact packaging machine. The single-acting pull design requires only one 3/2 valve, simplifying the pneumatic circuit while delivering reliable 134.4 N pull force at 0.7 MPa.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X20SCM with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X20SCM
To replace this MTAL20X20SCM, confirm the 20 mm bore, 20 mm stroke, PT G1/8 port, M8x1.25 rod thread, CM round-end back cover, and the -S magnet. The MTBL20X20SCM is the drop-in upgrade, but note the sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG. Remember the 0.2 MPa minimum pressure and apply no external load on the spring extend stroke, as the fail-safe home is extended.
For sizing, stepping down is not an option as 20 mm is the smallest available bore. Stepping up to the 32 mm bore provides a 261.2 N pull force at 0.5 MPa, offering a significant margin if your 81.7 N requirement grows.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X20SCM (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X20SCM instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X20SCM FAQ
Yes, the MTAL20X20SCM is discontinued. The exact drop-in replacement is the MTBL20X20SCM, which matches the 20 mm bore, 20 mm stroke, G1/8 port, and CM mounting. You will need to upgrade your sensors, as the MTAL uses CS1-M/DS1-M switches while the MTBL uses CMSG/DMSG/EMSG switches.
It is a single-acting pull cylinder where air retracts the rod and a spring extends it. The fail-safe home position is extended. The usable pull force is 81.7 N at 0.5 MPa and 134.4 N at 0.7 MPa, with a minimum operating pressure of 0.2 MPa.
