This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X20SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X20SCA 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 MTAL40X20SCA
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X20SCA is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø40mm bore and 20mm stroke, G1/4 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X20SCA.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X20SCA
The AirTAC MTAL40X20SCA is a discontinued single-acting pull-type mini cylinder. Air retracts the rod while an internal spring extends it, yielding a fail-safe extended home position. This 40mm bore provides a usable pull force of 439.4 N at 0.5 MPa. The exact drop-in replacement is the MTBL40X20SCA, matching the 20mm stroke, G1/4 port, and CA clevis.
This SKU includes the -S magnet for CS1-M or DS1-M switches; the MTBL upgrade uses CMSG, DMSG, or EMSG sensors. The MTAL features threaded covers, while the MTBL uses a riveted rolling-packed body. It uses a fixed rubber bumper for end-of-stroke damping. Apply no external load on the spring extend stroke to avoid damage.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X20SCA Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X20SCA |

| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X20SCA |
| Bore size | Ø40 mm |
| Stroke | 20 mm |
| Acting type | Single acting, pull (spring extend) |
| Port size | G1/4 |
| Rod thread | M12×1.25 |
| 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X20SCA carries the same single-acting ratings.
Usable Pull Force (Ø40mm)
| Pressure | Pull force (net of spring) |
|---|---|
| 0.5 MPa | 439.4 N |
| 0.7 MPa | 650.4 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 MTAL40X20SCA Is Used
Packaging Flap Folder
Pulls cardboard carton flaps down on a packaging line using 439.4 N at 0.5 MPa, relying on the spring-extended fail-safe to release the box cleanly.
Press Brake Tooling Retract
Draws a small upper die back on a sheet metal press. The CA clevis swings on a pin to absorb arcing tool motion during the 20mm pull.
Textile Loom Latch
Retracts a fabric tensioning latch on a weaving loom. The fixed rubber bumper absorbs the 20mm stroke impact without needing adjustment.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X20SCA with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X20SCA
Replace your MTAL40X20SCA with the MTBL40X20SCA. Confirm the 40mm bore, 20mm stroke, M12x1.25 rod-end thread, PT G1/4 port, and CA pivot back cover. Remember the 0.2 MPa minimum operating pressure and that the fail-safe home is extended. The -S magnet requires switching from CS1-M/DS1-M to CMSG/DMSG/EMSG switches.
For sizing, the 40mm bore yields 439.4 N pull at 0.5 MPa. If you need less force, step down to the 32mm bore (261.2 N at 0.5 MPa). If 40mm is the largest standard size here, it provides the maximum 650.4 N at 0.7 MPa. Keep the 20mm stroke short to minimize rod bending and side-load wear.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X20SCA (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X20SCA instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X20SCA FAQ
Yes, the MTAL40X20SCA is discontinued. The exact drop-in replacement is the MTBL40X20SCA. It matches the 40mm bore, 20mm stroke, G1/4 port, and CA clevis. You must update your sensors: the MTAL -S magnet used CS1-M or DS1-M switches, while the MTBL uses CMSG, DMSG, or EMSG switches.
The usable pull force is 439.4 N at 0.5 MPa and 650.4 N at 0.7 MPa. The operating pressure is 0.2-1.0 MPa. It is a single-acting pull cylinder: air retracts the rod and the spring extends it. The fail-safe home position is extended, and you must not apply an external load on the spring extend stroke.
