This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X30SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X30SU 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 MTAL40X30SU
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X30SU is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø40mm bore and 30mm 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X30SU.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X30SU
The AirTAC MTAL40X30SU is a discontinued single-acting pull-type mini cylinder with a 40mm bore and 30mm stroke. Air retracts the rod to do the work, while an internal spring extends it back out when air is released. The fail-safe home position is extended. It delivers a usable pull force of 439.4 N at 0.5 MPa and 650.4 N at 0.7 MPa.
The exact drop-in replacement is the MTBL40X30SU, matching the bore, stroke, G1/4 port, and U back cover. This MTAL40X30SU features a -S magnet for CS1-M or DS1-M switches; the MTBL replacement upgrades this to CMSG, DMSG, or EMSG sensors. This older MTAL uses threaded covers, whereas the MTBL features a riveted rolling-packed body. Apply no external load on the spring extend stroke.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X30SU Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X30SU |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X30SU |
| Bore size | Ø40 mm |
| Stroke | 30 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X30SU 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 MTAL40X30SU Is Used
Injection Mold Ejector Pull
Retracts an ejection pin in a 40mm bore injection molding setup with 439.4 N pull at 0.5 MPa, relying on spring extend to clear the mold safely on air loss.
Packaging Flap Drawbar
Pulls a carton sealing flap closed using 650.4 N at 0.7 MPa. The U flat-end back cover mounts rigidly to the packaging frame while the spring extends to release the flap.
Press Brake Tension Release
Draws back a heavy mechanical tension latch on a press brake. The 40mm bore handles the high load, and the fail-safe extended position unlocks the brake during an air loss event.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X30SU with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X30SU
To replace this MTAL40X30SU, specify the MTBL40X30SU. Confirm the 40mm bore, 30mm stroke, G1/4 port, PT thread, U flat-end back cover, and the -S magnet (noting the sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG). Remember the 0.2 MPa minimum operating pressure and that the fail-safe home is extended.
If sizing up or down, the next size down is the 32mm bore (G1/8 port, 261.2 N pull at 0.5 MPa), and the next size up is not available in this mini series as 40mm is the largest. The 40mm bore provides the highest standard pull force available. At 30mm stroke, end-of-stroke impact is low, but the fixed rubber bumper still absorbs the retract energy.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X30SU (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X30SU instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X30SU FAQ
Yes, the MTAL40X30SU is discontinued. The exact drop-in replacement is the MTBL40X30SU, which matches the 40mm bore, 30mm stroke, G1/4 port, and U back cover. The MTBL upgrades the body to a riveted rolling-packed design and changes the -S magnet compatibility from CS1-M/DS1-M switches to CMSG/DMSG/EMSG sensors.
The usable pull force is 439.4 N at 0.5 MPa and 650.4 N at 0.7 MPa. It is a single-acting pull cylinder, meaning air retracts the rod and an internal spring extends it. The fail-safe home position is extended, requiring a minimum of 0.2 MPa to retract. The fixed rubber bumper absorbs the retract impact.
