This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30SCA 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 MSAL20X30SCA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X30SCA is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø20mm bore and 30mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30SCA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X30SCA
The AirTAC MSAL20X30SCA is a discontinued single-acting push mini cylinder with a 20 mm bore and 30 mm stroke. Air extends the rod for the work stroke, while an internal spring retracts it to a fail-safe home when air is released. This SKU includes the -S magnet for position sensing and the CA back cover, which provides a pivot clevis for arcing loads. The exact drop-in replacement is the MSBL20X30SCA, matching the bore, stroke, force, and port.
At 0.5 MPa, this bore provides 106.8 N of usable push force (169.6 N at 0.7 MPa), already net of the return spring. The MSAL uses older CS1-M or DS1-M reed switches with its magnet, whereas the MSBL replacement upgrades to CMSG, DMSG, or EMSG sensors. Additionally, the MSAL features threaded covers, while the MSBL uses a riveted rolling-packed body. A fixed rubber bumper absorbs end-of-stroke impact, as there is no adjustable cushion.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X30SCA Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL20X30SCA |

| Bore size | Ø20 mm |
| Stroke | 30 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30SCA 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 MSAL20X30SCA Is Used
PCB Router Ejector
Pushes singulated printed circuit boards out of a routing fixture with 106.8 N at 0.5 MPa, relying on the spring return to retract the 8 mm rod clear of the workspace.
Packaging Flap Folder
Extends to fold cardboard carton flaps during continuous motion, using the CA pivot clevis to absorb the arcing load as the packaging moves downstream.
Sensor Tray Sorter
Indexes shallow plastic trays at an inspection station; the fail-safe spring return guarantees the mechanism pulls back to a safe home position on air loss.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X30SCA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30SCA
To replace the MSAL20X30SCA, specify the MSBL20X30SCA and confirm the 20 mm bore, 30 mm stroke, G1/8 port, PT thread, CA pivot back cover, and the -S magnet. Remember that the MSBL sensor family changes to CMSG, DMSG, or EMSG. Minimum working pressure is 0.2 MPa to overcome the spring. Apply no external load on the spring return stroke.
For sizing flexibility, stepping down is not an option as 20 mm is the smallest available bore. Stepping up to the 25 mm bore increases the 0.5 MPa push force to 176.4 N, providing extra margin if your 106.8 N output is insufficient. At this 30 mm stroke, side-load and rod-bending risks are minimal, but ensure the CA clevis pin is lubricated to handle any angular arc.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30SCA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30SCA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X30SCA FAQ
Yes, the AirTAC MSAL20X30SCA is discontinued. The exact drop-in replacement is the MSBL20X30SCA, matching the 20 mm bore, 30 mm stroke, G1/8 port, CA back cover, and single-acting push function. You only need to update your position sensors, as the MSBL uses CMSG, DMSG, or EMSG switches instead of the older CS1-M or DS1-M.
The 20 mm bore single-acting push force is 12.6 N at 0.2 MPa, 44.0 N at 0.3 MPa, 75.4 N at 0.4 MPa, 106.8 N at 0.5 MPa, 138.2 N at 0.6 MPa, and 169.6 N at 0.7 MPa (max 17.3 kgf). These figures are net of the return spring. The cylinder requires a minimum of 0.2 MPa air pressure to overcome the spring and extend the rod.
