This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X15U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X15U 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 MTAL20X15U
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X15U is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø20mm bore and 15mm 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 drop-in replacement is the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X15U.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X15U
The AirTAC MTAL20X15U is a discontinued single-acting pull-type mini cylinder. Air retracts the 8mm rod for a 15mm work stroke, while an internal spring extends it. It yields a usable pull force of 81.7 N at 0.5 MPa. The exact drop-in replacement is the MTBL20X15U, matching the 20mm bore, G1/8 port, and U flat-end cover.
This SKU lacks the -S magnet and cannot take a position sensor. The MTAL uses threaded covers and PT port form, whereas the MTBL upgrade features a riveted rolling-packed body. Both share a fixed rubber bumper and a fail-safe extended home position on air loss.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X15U Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X15U |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X15U |
| Bore size | Ø20 mm |
| Stroke | 15 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X15U 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 MTAL20X15U Is Used
Textile Loom Tension Gate
Pulls a yarn tensioning gate closed against its frame with 81.7 N at 0.5 MPa, releasing the warp automatically via spring-extend on air loss.
Electronic Tester Probe Lift
Retracts a spring-loaded test probe head 15mm away from PCB pads during board transport, extending safely to clear the fixture when air is dropped.
Packaging Carton Flap Catch
Draws back a small mechanical latch to release folded carton side flaps on a 15mm stroke, parking the latch extended out of the way during idle.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X15U with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X15U
To replace this MTAL20X15U, order the MTBL20X15U. Confirm the 20mm bore, 15mm stroke, G1/8 port, PT thread, and U flat-end cover. Because this SKU has no -S magnet, it cannot accept a sensor; the MTBL uses CMSG/DMSG/EMSG switches if you need to add one. Minimum working pressure is 0.2 MPa.
If sizing up, the 25mm bore provides 137.2 N at 0.5 MPa. If sizing down, there is no smaller standard MAL bore. Remember the fail-safe home is extended, and apply no external load on the spring extend stroke.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X15U (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X15U instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X15U FAQ
Yes, the MTAL20X15U is discontinued. The exact drop-in replacement is the MTBL20X15U, matching the 20mm bore, 15mm stroke, G1/8 port, and U flat-end cover. The MTBL upgrades the body to a riveted rolling-packed design but retains the same force class.
It is a single-acting pull cylinder with a fixed rubber bumper. Usable pull force is 81.7 N at 0.5 MPa and 134.4 N at 0.7 MPa, requiring a 0.2 MPa minimum pressure. The fail-safe home is extended, meaning the internal spring pushes the rod out on air loss.
