This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL25X5SU, 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 MSAL25X5SU
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL25X5SU is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø25mm bore and 5mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X5SU.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X5SU
The AirTAC MSAL25X5SU is a discontinued single-acting push mini cylinder with a 5 mm stroke and 25 mm bore. Air extends the rod while an internal spring retracts it, providing a fail-safe home position on air loss. It yields a usable push force of 176.4 N at 0.5 MPa. The direct replacement is the MSBL25X5SU, matching the bore, stroke, force, and G1/8 port.
This SKU includes the -S magnet for CS1-M or DS1-M switches; the MSBL upgrade uses CMSG, DMSG, or EMSG sensors. The MSAL features threaded covers, whereas the MSBL uses a riveted rolling-packed body. It has a fixed rubber bumper, a PT tapered port thread, and a U flat-end back cover for rigid rear mounting.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X5SU Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL25X5SU |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X5SU |
| Bore size | Ø25 mm |
| Stroke | 5 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X5SU 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 MSAL25X5SU Is Used
PCB Ejector Pin
Uses the 176.4 N push force at 0.5 MPa to eject finished printed circuit boards from a test fixture, relying on the spring return to clear the pin for the next panel.
Small Part Stamping
Provides a short 5 mm work stroke for light-duty contact stamping in electronic connector manufacturing, where the fail-safe retracted home prevents double-hits on air loss.
Pneumatic Detent Gate
Shifts a short diverter gate in packaging machinery; the U flat-end cover mounts rigidly to the machine frame while the spring holds the gate closed during pressure drops.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X5SU with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X5SU
To replace this MSAL25X5SU, order the MSBL25X5SU to match the 25 mm bore, 5 mm stroke, G1/8 port, PT thread, U back cover, and -S magnet (noting the sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG). Ensure your air supply meets the 0.2 MPa minimum to overcome the return spring, and apply no external load on the return stroke.
For sizing, step down to the 20 mm bore if 106.8 N at 0.5 MPa is sufficient, or step up to the 32 mm bore if you need 317.7 N at 0.5 MPa. The 5 mm stroke is highly compact, minimizing rod-bending side-load risks common in longer small-bore cylinders.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X5SU (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X5SU instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X5SU FAQ
Yes, the MSAL25X5SU is discontinued. The direct replacement is the MSBL25X5SU, which matches the 25 mm bore, 5 mm stroke, G1/8 port, and U back cover. You will need to update your sensors, as the MSAL -S magnet uses CS1-M/DS1-M switches while the MSBL uses CMSG/DMSG/EMSG.
The usable push force is 176.4 N at 0.5 MPa and 274.5 N at 0.7 MPa. The operating pressure range is 0.2-1.0 MPa, with a 0.2 MPa minimum required to overcome the internal return spring. The maximum force is 274.5 N (about 28 kgf).
