This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X125SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X125SCA 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 MSAL Front Single Acting Compact Cylinder MSAL20X125SCA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X125SCA is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø20mm bore and 125mm stroke, G1/8 ports and a fixed rubber bumper. Air drives the push (work) stroke and the spring returns the rod — it rests retracted on air loss. This model is discontinued; the drop-in replacement is the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X125SCA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X125SCA
The AirTAC MSAL20X125SCA is a discontinued single-acting push mini cylinder with a 125 mm stroke. Air extends the rod, and an internal spring retracts it to a fail-safe home when pressure drops. The 20 mm bore generates 106.8 N of usable push force at 0.5 MPa and 169.6 N at 0.7 MPa. The exact drop-in replacement is the MSBL20X125SCA, matching the bore, stroke, force, and CA clevis.
This SKU includes the -S magnet for position sensing. The older MSAL works with CS1-M and DS1-M reed switches, while the MSBL replacement upgrades to CMSG, DMSG, and EMSG sensors. The MSAL features threaded covers, whereas the MSBL uses a riveted rolling-packed body. Both retain a fixed rubber bumper, as single-acting mini cylinders lack adjustable cushions.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X125SCA Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL20X125SCA |

| Bore size | Ø20 mm |
| Stroke | 125 mm |
| Acting type | Single acting, push (spring return) |
| 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 150 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X125SCA carries the same single-acting ratings.
Usable Push Force (Ø20mm)
| Pressure | Push force (net of spring) |
|---|---|
| 0.5 MPa | 106.8 N |
| 0.7 MPa | 169.6 N |
Usable single-acting force after the return spring — lower than a same-bore double-acting cylinder. Size with a margin.

Where the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X125SCA Is Used
PCB Ejector Pins
Pushes finished printed circuit boards out of an assembly fixture using 106.8 N at 0.5 MPa, with the spring safely retracting the pin before the next panel loads.
Textile Loom Diverter
Arcs a thread guide out of the weave path. The CA pivot clevis accommodates the swing, while the fail-safe spring home clears the loom on air loss.
Light Packaging Flap
Holds a carton flap open for product insertion. The 125 mm stroke reaches across small boxes, and the spring returns the arm without needing a second air line.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X125SCA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X125SCA
Replace this MSAL20X125SCA directly with the MSBL20X125SCA. Confirm the 20 mm bore, 125 mm stroke, G1/8 PT port, M8x1.25 rod-end thread, and CA pivot back cover. Swap your CS1-M or DS1-M sensors for CMSG, DMSG, or EMSG switches. Remember the 0.2 MPa minimum operating pressure required to overcome the return spring, and never apply an external load on the spring return stroke.
For sizing flexibility, stepping down is not an option as 20 mm is the smallest bore. Stepping up to a 25 mm bore increases the push force to 176.4 N at 0.5 MPa. Because this 125 mm stroke is long for a 20 mm bore, be cautious of side loads that could cause rod bending.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X125SCA (same bore/stroke/force)
- ✓ Same push direction and retracted 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X125SCA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X125SCA FAQ
Yes, the MSAL20X125SCA is discontinued. The exact drop-in replacement is the MSBL20X125SCA, which matches the 20 mm bore, 125 mm stroke, CA clevis, and force class. You will only need to update your position sensors from the older CS1-M or DS1-M to the newer CMSG, DMSG, or EMSG switches.
This single-acting push cylinder provides a usable force of 12.6 N at 0.2 MPa, 106.8 N at 0.5 MPa, and a maximum of 169.6 N at 0.7 MPa. It requires a minimum operating pressure of 0.2 MPa to overcome the internal return spring. The maximum force is approximately 17.3 kgf.
