This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL25X40U, 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 MSAL25X40U
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL25X40U 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X40U.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X40U
The AirTAC MSAL25X40U is a discontinued 25mm bore, 40mm stroke single-acting push cylinder. 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 MSBL25X40U, matching the bore, stroke, PT G1/8 port, and U flat-end back cover.
Because this SKU lacks the -S suffix, it has no magnet and cannot accept a position sensor. Upgrading to the MSBL25X40U brings a riveted rolling-packed body instead of the older MSAL threaded covers. If you ever need a sensor, the MSBL uses modern CMSG/DMSG/EMSG switches rather than the legacy CS1-M/DS1-M family.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X40U Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL25X40U |

| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X40U |
| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X40U 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 MSAL25X40U Is Used
PCB Router Ejector
Deploys 40mm to push singulated circuit boards out of a routing fixture with 176.4 N at 0.5 MPa, retracting automatically when the 3/2 valve vents.
Bottle Flap Folder
Tucks carton flaps on a packaging line; the spring return provides a fail-safe retracted home if the air supply drops, preventing jams.
Indexer Detent Pin
Extends a 10mm rod to lock a rotary table in place, using the fixed rubber bumper to absorb the stop impact without adjustable cushions.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X40U with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X40U
To replace this MSAL25X40U, order the MSBL25X40U and confirm the 25mm bore, 40mm stroke, PT G1/8 port, and U flat-end back cover. The minimum working pressure remains 0.2 MPa to overcome the return spring, and you must apply no external load on the spring return stroke. At 40mm stroke on this compact bore, rod-bending side loads are a real risk—keep the load purely axial.
To size either way: stepping down to a 20mm bore drops your 0.5 MPa push force to 106.8 N, while stepping up to a 32mm bore raises it to 317.7 N. This 25mm bore gives 176.4 N at 0.5 MPa and 274.5 N at 0.7 MPa, hitting a solid middle ground for light-duty ejection.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X40U (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X40U instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X40U FAQ
Yes, the MSAL25X40U is discontinued. The direct replacement is the MSBL25X40U, which matches the 25mm bore, 40mm stroke, PT G1/8 port, and U back cover. The MSBL upgrades the body to a riveted rolling-packed design and uses CMSG/DMSG/EMSG sensors if you add a magnet.
The 25mm bore single-acting push force is 176.4 N at 0.5 MPa and 274.5 N at 0.7 MPa. The minimum operating pressure is 0.2 MPa because the air must overcome the internal return spring. This SKU has no -S magnet, so it cannot take a position sensor.
