This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL25X150SU, 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 MSAL25X150SU
The AirTAC MSAL Front Single Acting Compact Cylinder MSAL25X150SU is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø25mm bore and 150mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X150SU.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X150SU
The AirTAC MSAL25X150SU is a discontinued single-acting push, spring-return mini cylinder. Air extends the 150mm stroke, while an internal spring retracts it to a fail-safe home on air loss. It delivers 176.4 N of usable push force at 0.5 MPa. The direct replacement is the MSBL25X150SU, matching the 25mm bore, stroke, G1/8 port, and U back cover.
This SKU features a -S magnet for position sensing via older CS1-M or DS1-M switches; the MSBL successor upgrades to CMSG, DMSG, or EMSG sensors. The MSAL uses threaded covers, whereas the MSBL features a riveted rolling-packed body. A fixed rubber bumper absorbs end-of-stroke impact, as no adjustable cushion exists. Apply no external load on the return stroke, as the spring is not designed to pull external weight.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X150SU Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL25X150SU |

| Bore size | Ø25 mm |
| Stroke | 150 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X150SU 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 MSAL25X150SU Is Used
PCB Router Ejector
Pushes cut printed circuit boards out of a routing fixture with 176.4 N at 0.5 MPa; the spring return clears the ejector pin before the next panel loads.
Blister Pack Flap Closer
Presses cardboard backing onto plastic blister trays; the fail-safe retracted home ensures the line can index forward even if air pressure drops.
Conveyor Diverter Gate
Extends a 150mm guide rail to deflect small plastic bottles to a packaging lane, relying on the fixed rubber bumper to absorb the stroke impact.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X150SU with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X150SU
To replace the MSAL25X150SU, use the MSBL25X150SU. Confirm the 25mm bore, 150mm stroke, G1/8 port, PT thread, U flat-end back cover, and -S magnet. Remember the sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG. Maintain a minimum 0.2 MPa air pressure to overcome the return spring. At 150mm stroke on a 25mm bore, prevent rod bending by ensuring strict alignment and avoiding side loads.
For sizing, step down to the 20mm bore (106.8 N push at 0.5 MPa) for lighter ejection tasks. Step up to the 32mm bore (317.7 N push at 0.5 MPa) if your application requires higher pressing force.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X150SU (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X150SU instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X150SU FAQ
Yes, the MSAL25X150SU is discontinued. The direct replacement is the MSBL25X150SU, which matches the 25mm bore, 150mm stroke, G1/8 port, and U back cover. The MSBL upgrades the sensor switches to CMSG/DMSG/EMSG and uses a riveted body instead of threaded covers.
The 25mm bore provides 176.4 N of usable push force 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 to extend the rod.
