This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X25SCM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X25SCM 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 MTAL40X25SCM
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X25SCM is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø40mm bore and 25mm 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X25SCM.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X25SCM
The AirTAC MTAL40X25SCM is a discontinued single-acting pull mini cylinder with a 40 mm bore and 25 mm stroke. Air retracts the rod while an internal spring extends it, yielding 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 MTBL40X25SCM, matching the G1/4 port, M12x1.25 rod thread, and CM round-end back cover.
This SKU includes the -S magnet for CS1-M or DS1-M switches, whereas the MTBL replacement uses CMSG, DMSG, or EMSG sensors. The MTAL features threaded covers and a fixed rubber bumper, while the current MTBL uses a riveted rolling-packed body. The fail-safe home is extended, meaning air loss pushes the rod out.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X25SCM Technical Specifications

| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X25SCM |
| Bore size | Ø40 mm |
| Stroke | 25 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X25SCM 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 MTAL40X25SCM Is Used
Injection Mold Ejector
Pulls an injection mold ejector pin back against 439.4 N at 0.5 MPa, using the spring-extend fail-safe to safely clear the mold cavity on air loss.
Packaging Flap Tensioner
Draws back a packaging carton flap tensioner with a 25 mm stroke, relying on the fixed rubber bumper to absorb the 650.4 N peak force at 0.7 MPa.
Stamping Press Blank Holder
Retracts a stamping press blank holder using the 40 mm bore, ensuring the mechanism parks extended via the internal spring during an emergency stop.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X25SCM with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X25SCM
To replace this MTAL40X25SCM with the MTBL40X25SCM, verify the 40 mm bore, 25 mm stroke, PT G1/4 port, and CM round-end back cover. Remember the sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG. Operating pressure must be at least 0.2 MPa. Apply no external load on the spring extend stroke, and expect the rod to park extended upon air loss.
For sizing, stepping down to the 32 mm bore gives a 261.2 N pull at 0.5 MPa. If you need more force, 40 mm is the largest standard MTAL bore, delivering 650.4 N at 0.7 MPa. The fixed rubber bumper absorbs end-of-stroke impact without mid-stroke load holding.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X25SCM (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X25SCM instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X25SCM FAQ
Yes, the MTAL40X25SCM is discontinued. The exact drop-in replacement is the MTBL40X25SCM, which matches the 40 mm bore, 25 mm stroke, G1/4 port, and CM mounting. You only need to upgrade your CS1-M/DS1-M sensors to the CMSG/DMSG/EMSG family.
The single-acting pull force is 439.4 N at 0.5 MPa and 650.4 N at 0.7 MPa. It operates on 0.2 to 1.0 MPa pressure with a 50-800 mm/s speed range. The maximum standard stroke is 100 mm, and it uses a fixed rubber bumper.
