This model is discontinued
AirTAC has phased out the MTAL series. You can still order this code here: we ship the direct replacement MTBL20X40SCM, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 MTAL20X40SCM
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X40SCM is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø20mm bore and 40mm stroke, G1/8 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 direct replacement is the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X40SCM.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X40SCM
The AirTAC MTAL20X40SCM is a discontinued single-acting pull, spring-extend mini cylinder. Air retracts the rod while an internal spring extends it. It delivers 81.7 N of usable pull force at 0.5 MPa. The direct replacement is the MTBL20X40SCM.
This 20mm bore unit uses a G1/8 port and an M8x1.25 rod thread. It includes a -S magnet for position sensing. The MTAL uses CS1-M or DS1-M switches with threaded covers. The MTBL upgrade features a riveted rolling-packed body and CMSG, DMSG, or EMSG sensors. A fixed rubber bumper absorbs end-of-stroke impact. Remember to apply no external load on the spring extend stroke.

| Bore size | Ø20 mm |
| Stroke | 40 mm |
| Acting type | Single acting, pull (spring extend) |
| Port size | G1/8 |
| Rod thread | M8×1.25 |
| 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X40SCM carries the same single-acting ratings.
Usable Pull Force (Ø20mm)
| Pressure | Pull force (net of spring) |
|---|---|
| 0.5 MPa | 81.7 N |
| 0.7 MPa | 134.4 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 MTAL20X40SCM Is Used
Packaging Flap Closer
Uses 81.7 N at 0.5 MPa to pull cardboard carton flaps tight during sealing. The spring-extended fail-safe releases the flap if compressed air drops.
Lathe Chuck Ejector
Draws back a small workpiece retention pin on a CNC lathe. The 8mm rod handles the lateral pull while air loss safely pushes the pin out.
PCB Test Fixture Latch
Retracts a locking gate on an electronics test rig. The CS1-M sensor confirms retraction before the test head descends.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X40SCM with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X40SCM
To replace the MTAL20X40SCM, install the MTBL20X40SCM. Confirm the 20mm bore, 40mm stroke, G1/8 port, PT thread, CM round-end cover, and magnet are retained. The sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG. Maintain a minimum 0.2 MPa operating pressure and note the fail-safe home is extended.
If sizing force, stepping down is not possible as 20mm is the smallest bore. Stepping up to the 32mm bore yields 261.2 N of pull force at 0.5 MPa. The 40mm stroke is under the 100mm standard limit, avoiding rod-bending side-load risks.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X40SCM (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X40SCM instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X40SCM FAQ
Yes, the MTAL20X40SCM is discontinued. The direct replacement is the MTBL20X40SCM, matching the 20mm bore, 40mm stroke, G1/8 port, and CM cover. You must upgrade your sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG.
It is single-acting pull with spring extend. Usable pull force is 81.7 N at 0.5 MPa and 134.4 N at 0.7 MPa. The fail-safe home is extended. The maximum standard stroke is 100mm, operating pressure is 0.2-1.0 MPa, and speed is 50-800 mm/s.
