This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X50SCM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X50SCM 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 MTAL40X50SCM
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X50SCM is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø40mm bore and 50mm 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X50SCM.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X50SCM
The AirTAC MTAL40X50SCM is a discontinued single-acting pull-type mini cylinder with a 40 mm bore and 50 mm stroke. Air retracts the rod, and an internal spring extends it, providing a fail-safe extended home position. It delivers 439.4 N of usable pull force at 0.5 MPa. The exact drop-in replacement is the MTBL40X50SCM, matching the bore, stroke, G1/4 port, and CM mounting.
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 mechanical damage.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X50SCM Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X50SCM |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X50SCM |
| Bore size | Ø40 mm |
| Stroke | 50 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X50SCM 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 MTAL40X50SCM Is Used
Injection Mold Ejection
Pulls an ejection pin back inside an injection mold against 439.4 N at 0.5 MPa, ensuring the spring-extended fail-safe clears the parting line during an air loss event.
Packaging Flap Folding
Retracts a cardboard flap-folding arm on a packaging line, using the 50 mm stroke to clear the carton path while the spring safely extends the arm when air is cut.
CNC Lathe Chuck Tensioning
Draws back a secondary workpiece tensioning latch on a CNC lathe, utilizing the 16 mm rod and M12x1.25 thread to handle high dynamic pull forces safely.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X50SCM with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X50SCM
Replace the MTAL40X50SCM directly with the MTBL40X50SCM. Confirm the 40 mm bore, 50 mm stroke, G1/4 port, PT thread, CM round-end back cover, and the -S magnet (noting the sensor family change to CMSG/DMSG/EMSG). The system requires a minimum 0.2 MPa operating pressure to overcome the return spring. Remember that the fail-safe home is extended, and never apply external load to the spring extend stroke.
To size correctly, stepping down to the 32 mm bore yields 261.2 N of pull force at 0.5 MPa. As the largest standard size, 40 mm is the maximum bore available, providing 650.4 N at 0.7 MPa. The 16 mm rod and M12x1.25 rod-end thread handle high tension loads.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X50SCM (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X50SCM instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X50SCM FAQ
Yes, the AirTAC MTAL40X50SCM is discontinued. The exact drop-in replacement is the MTBL40X50SCM, which matches the 40 mm bore, 50 mm stroke, G1/4 port, and CM mounting. You must upgrade your sensors from the old CS1-M/DS1-M to the new CMSG/DMSG/EMSG family.
The usable pull force is 439.4 N at 0.5 MPa and 650.4 N at 0.7 MPa. The maximum standard stroke is 100 mm. Operating pressure must be between 0.2 and 1.0 MPa, with a minimum of 0.2 MPa required to overcome the return spring. The fail-safe home position is extended.
