This model is discontinued
AirTAC has phased out the MTAL series. You can still order this code here: we ship the direct replacement MTBL20X40CM, 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 MTAL20X40CM
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X40CM 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X40CM.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X40CM
The AirTAC MTAL20X40CM is a discontinued single-acting pull-type mini cylinder with a 20mm bore and 40mm stroke. Air retracts the rod while an internal spring extends it, providing a fail-safe extended home position. It delivers a usable pull force of 81.7 N at 0.5 MPa. The direct replacement is the MTBL20X40CM, which matches the bore, stroke, force, and port.
This MTAL features a CM round back cover, a fixed rubber bumper, and a G1/8 port. It uses threaded covers, whereas the MTBL upgrade uses a riveted rolling-packed body. This SKU lacks the -S magnet, so it cannot take a position sensor; the MTBL upgrade uses CMSG/DMSG/EMSG switches for magnetized versions. Apply no external load on the spring extend stroke.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X40CM Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X40CM |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X40CM |
| 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X40CM 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 MTAL20X40CM Is Used
Electronic Connector Pull
Draws back a test probe in an ICT fixture with 81.7 N at 0.5 MPa, relying on the spring-extended fail-safe to park the probe safely out of the test bed.
Textile Loom Tension
Retracts a yarn guide on a weaving machine; the single-acting pull mechanism and fixed rubber bumper absorb end-of-stroke shock in tight spaces.
PCB DepanelingLatch
Pulls a hold-down latch on a depaneling router; air retracts the 8mm rod to release the board, and the internal spring extends it to lock the part during air loss.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X40CM with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X40CM
To replace the MTAL20X40CM, use the MTBL20X40CM. Confirm the 20mm bore, 40mm stroke, G1/8 port, PT thread, CM round back cover, and 0.2 MPa minimum pressure. The fail-safe home is extended. Since this is the smallest bore, to step up use the 25mm bore (137.2 N at 0.5 MPa). The MTAL uses threaded covers and a fixed rubber bumper, while the MTBL features a riveted body. This no-S SKU cannot take a sensor.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X40CM (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X40CM instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X40CM FAQ
Yes, the MTAL20X40CM is discontinued. The direct replacement is the MTBL20X40CM, which matches the 20mm bore, 40mm stroke, CM cover, and G1/8 port. The MTBL upgrades the threaded covers to a riveted rolling-packed body.
It is a single-acting pull cylinder, so air retracts the rod and the spring extends it. The fail-safe home is extended. The usable pull force is 81.7 N at 0.5 MPa and 134.4 N at 0.7 MPa, with a minimum working pressure of 0.2 MPa. This no-S SKU cannot take a position sensor.
