This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL25X20SCA, 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 MSAL Front Single Acting Compact Cylinder MSAL25X20SCA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL25X20SCA is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø25mm bore and 20mm 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 direct replacement is the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X20SCA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X20SCA
The AirTAC MSAL25X20SCA is a discontinued single-acting push mini cylinder with a 25 mm bore and 20 mm stroke. Air extends the rod to deliver 176.4 N of usable push force at 0.5 MPa, while an internal spring retracts it for a fail-safe home on air loss. The direct replacement is the MSBL25X20SCA, matching your bore, stroke, G1/8 port, and CA mounting.
This SKU features a -S magnet for position sensing, but the older MSAL uses CS1-M or DS1-M switches while the MSBL upgrade takes CMSG, DMSG, or EMSG sensors. The MSAL uses threaded covers, whereas the MSBL features a riveted rolling-packed body. A CA back cover provides a pivot clevis for arcing loads, and end-of-stroke energy is absorbed by a fixed rubber bumper.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X20SCA Technical Specifications

| Bore size | Ø25 mm |
| Stroke | 20 mm |
| Acting type | Single acting, push (spring return) |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X20SCA carries the same single-acting ratings.
Usable Push Force (Ø25mm)
| Pressure | Push force (net of spring) |
|---|---|
| 0.5 MPa | 176.4 N |
| 0.7 MPa | 274.5 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 MSAL25X20SCA Is Used
PCB Router Clamping
Holds a printed circuit board flat against a vacuum fixture during routing, using 176.4 N of push at 0.5 MPa and retracting instantly when the 3/2 valve vents to release the panel.
Packaging Flap Fold
Pushes a cardboard carton flap into position at 274.5 N under 0.7 MPa, with the spring ensuring the mechanism retracts safely out of the product flow path during idle cycles.
Textile Yarn Tensioner
Applies steady outward pressure on a yarn tensioning bar; the CA pivot clevis accommodates the slight angular swing of the lever while the spring returns the bar if compressed air fails.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X20SCA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X20SCA
To replace the MSAL25X20SCA, install the direct replacement MSBL25X20SCA. Confirm the 25 mm bore, 20 mm stroke, PT G1/8 port, M10x1.25 rod thread, CA pivot back cover, and the sensor family change from CS1-M/DS1-M to CMSG/DMSG/EMSG. Maintain a minimum 0.2 MPa operating pressure to overcome the return spring, and apply no external load on the spring return stroke.
For sizing flexibility, stepping down to the 20 mm bore drops the 0.5 MPa push force to 106.8 N, while stepping up to the 32 mm bore increases it to 317.7 N. Given the 20 mm stroke on this small bore, keep the load perfectly axial to prevent rod binding and premature guide wear.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X20SCA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X20SCA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X20SCA FAQ
Yes, the MSAL25X20SCA is discontinued. The direct replacement is the MSBL25X20SCA, which matches the 25 mm bore, 20 mm stroke, 176.4 N push force at 0.5 MPa, 274.5 N at 0.7 MPa, and G1/8 port. You must only update your position sensors, as the MSBL uses CMSG, DMSG, or EMSG switches instead of the older CS1-M or DS1-M.
The minimum operating pressure is 0.2 MPa because the incoming air must first overcome the internal return spring. At 0.5 MPa the usable push force is 176.4 N, and at 0.7 MPa it reaches 274.5 N. These figures are already net of the spring force, which is not rated to hold external loads mid-stroke or on the return stroke.
