This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL25X40SCA, 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 MSAL25X40SCA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL25X40SCA is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø25mm bore and 40mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X40SCA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X40SCA
The AirTAC MSAL25X40SCA is a discontinued single-acting push cylinder with a 40mm stroke and spring return. Air extends the rod to deliver 176.4 N of usable push force at 0.5 MPa, while an internal spring retracts it to a fail-safe home when air is removed. The direct replacement is the MSBL25X40SCA, matching the bore, stroke, G1/8 port, and CA clevis mount.
This -S variant includes a magnet for position sensing. The legacy MSAL uses threaded covers and CS1-M or DS1-M switches, whereas the MSBL upgrade features a riveted rolling-packed body and uses CMSG, DMSG, or EMSG sensors. A fixed rubber bumper absorbs end-of-stroke impact, requiring no adjustment. Remember that the return spring opposes the air stroke, so never apply an external load on the retract motion.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X40SCA Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL25X40SCA |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |

| Bore size | Ø25 mm |
| Stroke | 40 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X40SCA 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 MSAL25X40SCA Is Used
PCB Router Clamping
Holds a printed circuit board panel against a router fixture using 176.4 N of push force at 0.5 MPa, releasing instantly via spring return when routing completes.
Packaging Flap Deflector
Extends 40mm to guide a carton flap during automated case erecting, relying on the fail-safe spring return to clear the path if compressed air drops out.
Textile Loom Tensioner
Pivots on the CA clevis to apply steady single-direction tension on a yarn guide, absorbing end-of-stroke shock through the fixed rubber bumper.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X40SCA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X40SCA
To replace this MSAL25X40SCA, install the MSBL25X40SCA and confirm the 25mm bore, 40mm stroke, M10x1.25 rod thread, PT port thread, and CA pivot clevis. Swap your CS1-M/DS1-M sensors for the MSBL's CMSG/DMSG/EMSG family. Maintain at least 0.2 MPa air pressure to overcome the return spring. If sizing a new application, step down to a 20mm bore for 106.8 N push at 0.5 MPa, or step up to a 32mm bore for 317.7 N. At this 40mm stroke, side-load risk is low, but ensure the CA clevis pin swings freely to prevent rod binding.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X40SCA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X40SCA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X40SCA FAQ
Yes, the MSAL25X40SCA is discontinued. The direct replacement is the AirTAC MSBL25X40SCA, matching the 25mm bore, 40mm stroke, G1/8 port, and CA mounting. You will need to upgrade your position sensors from the old CS1-M/DS1-M series to the CMSG/DMSG/EMSG series.
The usable push force is 176.4 N at 0.5 MPa and 274.5 N at 0.7 MPa, with a maximum force equivalent to 28 kgf. The operating pressure range is 0.2-1.0 MPa, and you must maintain at least 0.2 MPa for the air to overcome the internal return spring. It provides 29.2 N at this 0.2 MPa minimum.
