This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X15SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X15SCA 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 MTAL20X15SCA
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X15SCA 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X15SCA.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X15SCA
The AirTAC MTAL20X15SCA is a discontinued single-acting pull-type mini cylinder with a 20 mm bore and 15 mm stroke. Air retracts the rod, while an internal spring extends it, yielding a fail-safe extended home position. It delivers a usable pull force of 81.7 N at 0.5 MPa. The exact drop-in replacement is the MTBL20X15SCA, matching the bore, stroke, G1/8 port, and CA mounting.
This SKU includes the -S magnet for position sensing. On the MTAL, this uses the older CS1-M or DS1-M switches, while the MTBL20X15SCA upgrade requires CMSG, DMSG, or EMSG sensors. The MTAL features threaded covers and a fixed rubber bumper, whereas the current MTBL uses a riveted rolling-packed body. The CA back cover provides a pivot clevis that swings on a pin, ideal for arcing loads.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X15SCA Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X15SCA |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X15SCA |
| 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X15SCA 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 MTAL20X15SCA Is Used
Packaging Flap Pull-down
Retracts a carton sealing flap using 81.7 N of pull at 0.5 MPa. The spring-extend fail-safe clears the mechanism during an air loss event.
Lathe Chuck Guard
Pulls a safety guard closed during machining. The CA pivot clevis accommodates the arcing swing of the guard arm.
PCB Test Socket Release
Draws back an electronics test probe plate. The short 15 mm stroke and fixed rubber bumper ensure rapid, soft stops.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X15SCA with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X15SCA
To replace the MTAL20X15SCA, install the MTBL20X15SCA. Confirm the 20 mm bore, 15 mm stroke, M8x1.25 rod thread, G1/8 port, CA pivot back cover, and PT thread form. You must also swap your CS1-M or DS1-M sensors for CMSG, DMSG, or EMSG switches. Remember the 0.2 MPa minimum operating pressure and apply no external load on the spring-extend stroke, as the fail-safe home is extended.
When sizing, step down to the 20 mm bore if you need exactly 81.7 N of pull at 0.5 MPa. If your load requires more force, step up to the 25 mm bore, which provides 137.2 N of pull at 0.5 MPa. This 15 mm stroke is well under the 100 mm standard maximum, so rod bending is not a concern.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X15SCA (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X15SCA instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X15SCA FAQ
Yes, the MTAL20X15SCA is discontinued. The exact drop-in replacement is the MTBL20X15SCA, which matches the 20 mm bore, 15 mm stroke, G1/8 port, and CA mounting. You will need to upgrade your position sensors from the old CS1-M or DS1-M to the newer CMSG, DMSG, or EMSG switches.
It is a single-acting pull cylinder where air retracts the rod and a spring extends it. The fail-safe home position is extended. The usable pull force is 81.7 N at 0.5 MPa and 134.4 N at 0.7 MPa. It requires a minimum operating pressure of 0.2 MPa and uses a fixed rubber bumper.
