This model is discontinued
AirTAC has phased out the MTAL series. You can still order this code here: we ship the direct replacement MTBL20X50SCA, 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 MTAL20X50SCA
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X50SCA is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø20mm bore and 50mm 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X50SCA.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X50SCA
The AirTAC MTAL20X50SCA is a discontinued single-acting pull-type mini cylinder. Air retracts the rod while an internal spring extends it, meaning the fail-safe home position is fully extended. It delivers 81.7 N of usable pull force at 0.5 MPa. The direct replacement is the MTBL20X50SCA, matching the 20mm bore, 50mm stroke, G1/8 port, and CA clevis.
This SKU includes the -S magnet for CS1-M or DS1-M switches, whereas the MTBL replacement uses CMSG/DMSG/EMSG sensors. The MTAL features threaded covers and a fixed rubber bumper, while the MTBL upgrades to a riveted rolling-packed body. Apply no external load on the spring-extend stroke to avoid damage.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X50SCA Technical Specifications

| Bore size | Ø20 mm |
| Stroke | 50 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X50SCA 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 MTAL20X50SCA Is Used
Packaging Flap Folder
Pulls a cardboard carton flap down on a packaging line using 81.7 N at 0.5 MPa, letting the spring safely extend the arm clear between cycles.
PCB Router Gate
Retracts a safety guard on a PCB depaneling router, relying on the spring-extended fail-safe to open the gate instantly on air loss.
Textile Tension Arm
Draws back a textile thread tensioning arm out of the weave path, using the CA clevis to swing freely on arc loads.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X50SCA with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X50SCA
To replace the MTAL20X50SCA, install the MTBL20X50SCA. Confirm the 20mm bore, 50mm stroke, M8x1.25 rod thread, G1/8 PT port, CA pivot clevis, and -S magnet. The sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG. Maintain a minimum 0.2 MPa operating pressure and remember the fail-safe home is extended.
If sizing up or down, the next size up is the 25mm bore, yielding 137.2 N pull at 0.5 MPa. As the smallest standard bore, the next size down does not exist in this series. At 50mm stroke, keep the rod aligned to prevent side-load bending.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X50SCA (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X50SCA instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X50SCA FAQ
Yes, the MTAL20X50SCA is discontinued. The direct replacement is the MTBL20X50SCA, matching the 20mm bore, 50mm stroke, G1/8 port, and CA clevis. You only swap the sensor family from CS1-M/DS1-M to CMSG/DMSG/EMSG.
It is a single-acting pull cylinder with a fixed rubber bumper. Usable pull force is 81.7 N at 0.5 MPa and 134.4 N at 0.7 MPa. Operating pressure is 0.2-1.0 MPa, speed is 50-800 mm/s, and it cannot hold a load mid-stroke without an external device.
