This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X80U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X80U 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 MTAL40X80U
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X80U is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø40mm bore and 80mm 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X80U.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X80U
The AirTAC MTAL40X80U is a discontinued 40mm bore, 80mm stroke, single-acting pull-type 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 439.4 N at 0.5 MPa. The exact drop-in replacement is the MTBL40X80U, matching the bore, stroke, G1/4 port, and U flat-end cover.
This non-magnet SKU cannot accept a position sensor. The MTAL uses threaded covers and a fixed rubber bumper, whereas the MTBL upgrade features a riveted rolling-packed body. Apply no external load on the spring extend stroke. The original -S magnet used CS1-M or DS1-M switches; the MTBL replacement uses CMSG, DMSG, or EMSG sensors.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X80U Technical Specifications

|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X80U |
| Bore size | Ø40 mm |
| Stroke | 80 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X80U 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 MTAL40X80U Is Used
Packaging Flap Folding
Pulls cardboard carton flaps closed at 439.4 N during case erecting, relying on the spring to safely push the flap back open if air pressure drops.
PCB Test Socket Release
Retracts a 40mm bore test probe plate away from delicate circuit boards, using the fail-safe extended position to clear the test head during faults.
Textile Loom Tension Gate
Draws back a thread tensioning guide under air pressure, letting the internal spring push the guide out to maintain slack when the line stops.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X80U with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X80U
Replace this MTAL40X80U directly with the MTBL40X80U. Confirm the 40mm bore, 80mm stroke, G1/4 port, PT thread, U flat-end back cover, and lack of magnet. Remember the 0.2 MPa minimum operating pressure and the fail-safe extended home position. If stepping down, the 32mm bore neighbor provides 261.2 N pull at 0.5 MPa. If stepping up, 40mm is the largest standard MTAL bore, offering 650.4 N at 0.7 MPa. Never apply external load on the spring extend stroke.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X80U (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X80U instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X80U FAQ
Yes, the MTAL40X80U is discontinued. The exact drop-in replacement is the MTBL40X80U, which matches the 40mm bore, 80mm stroke, G1/4 port, and U flat-end cover. The MTBL upgrades the body to a riveted rolling-packed design.
This single-acting pull cylinder provides a usable pull force of 439.4 N at 0.5 MPa and 650.4 N at 0.7 MPa. It operates between 0.2 and 1.0 MPa. Because it is a pull-type with a fixed rubber bumper, it cannot hold a load mid-stroke, and the spring extends the rod on air loss.
