This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X40U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X40U 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 MTAL40X40U
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X40U is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø40mm bore and 40mm 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X40U.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X40U
The AirTAC MTAL40X40U is a discontinued single-acting pull-type mini cylinder. Air retracts the rod to do work, while an internal spring extends it back out. It delivers 439.4 N of usable pull force at 0.5 MPa. The exact drop-in replacement is the MTBL40X40U, matching the 40 mm bore, 40 mm stroke, G1/4 port, and U back cover.
This SKU has no magnet and cannot take a position sensor. If upgrading to the MTBL40X40U with a magnet, note the switch family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG. The MTAL uses threaded covers, whereas the MTBL features a riveted rolling-packed body. A fixed rubber bumper absorbs end-of-stroke impact, and the fail-safe home position is extended.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X40U Technical Specifications

| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X40U |
| Bore size | Ø40 mm |
| Stroke | 40 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X40U 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 MTAL40X40U Is Used
Injection Mold Ejection
Pulls a mold ejector pin back against the 439.4 N load at 0.5 MPa, using the spring-extended fail-safe to keep the pin clear during mold open.
Packaging Flap Tensioning
Draws back a carton flap tensioner on a packaging line, relying on the 40 mm bore and fixed rubber bumper to absorb the pull impact.
Textile Loom Lever Reset
Retracts a loom tensioning lever out of the warp threads, allowing the internal spring to safely push the lever back to its extended home on air loss.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X40U with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X40U
To replace this MTAL40X40U with the MTBL40X40U, confirm the 40 mm bore, 40 mm stroke, G1/4 port, PT thread, and U flat-end back cover. Because this SKU lacks an -S magnet, it cannot accept a sensor. The minimum operating pressure is 0.2 MPa, and you must apply no external load on the spring extend stroke. On air loss, the rod fails safe to the extended position.
If sizing up or down, the next size down is the 32 mm bore (G1/8 port, 261.2 N pull at 0.5 MPa). The 40 mm bore is the largest in this series, delivering 650.4 N at 0.7 MPa. Since the stroke is under 100 mm, standard rod-bending limits apply.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X40U (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X40U instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X40U FAQ
Yes, the MTAL40X40U is discontinued. The exact drop-in replacement is the MTBL40X40U, which matches the 40 mm bore, 40 mm stroke, G1/4 port, and U back cover. The MTBL upgrades the body to a riveted rolling-packed design.
It is a single-acting pull cylinder with a fixed rubber bumper. Usable pull force is 439.4 N at 0.5 MPa and 650.4 N at 0.7 MPa. The fail-safe home is extended, meaning the spring pushes the rod out on air loss. It requires a minimum of 0.2 MPa to retract the rod.
