This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL25X25SU, 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 MSAL25X25SU
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL25X25SU is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø25mm bore and 25mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X25SU.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X25SU
The AirTAC MSAL25X25SU is a discontinued single-acting push cylinder with a 25mm bore and 25mm stroke. Air extends the rod to do work, while an internal spring retracts it to a fail-safe home when air is removed. It delivers a usable push force of 176.4 N at 0.5 MPa. The direct replacement is the MSBL25X25SU, matching the bore, stroke, G1/8 port, and U back cover.
This U-coded SKU features a flat-end rear cover for rigid mounting. It includes the -S magnet for position sensing, but the older MSAL uses CS1-M or DS1-M switches, whereas the current MSBL uses CMSG, DMSG, or EMSG sensors. The legacy MSAL has threaded covers, while the MSBL features a riveted rolling-packed body. Both use a fixed rubber bumper, as there is no adjustable cushion on this single-acting type.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X25SU Technical Specifications

| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X25SU |
| Bore size | Ø25 mm |
| Stroke | 25 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X25SU 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 MSAL25X25SU Is Used
PCB Ejector Pin
Pushes finished printed circuit boards out of a test fixture using 176.4 N at 0.5 MPa, relying on the spring to retract the pin safely when air is cut.
Packaging Flap Hold
Extends to hold a carton flap stationary during a taping cycle, with the fail-safe home ensuring the flap releases automatically if air pressure drops.
Light Stamping Detent
Provides a short 25mm work stroke to press a small detent into a sheet metal bracket, benefiting from the fixed rubber bumper to absorb end-of-stroke impact.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X25SU with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X25SU
To replace this MSAL25X25SU, install the MSBL25X25SU. Confirm the 25mm bore, 25mm stroke, M10x1.25 rod thread, PT port, and the U flat-end back cover. If you need to step down, the 20mm bore offers 106.8 N at 0.5 MPa. If you need to step up, the 32mm bore provides 317.7 N at 0.5 MPa. Remember the 0.2 MPa minimum pressure required to overcome the return spring, and never apply an external load on the spring return stroke.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X25SU (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X25SU instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X25SU FAQ
Yes, the MSAL25X25SU is discontinued. The direct replacement is the AirTAC MSBL25X25SU. It matches the 25mm bore, 25mm stroke, single-acting push function, and G1/8 port. You will only need to update your position sensors, as the MSBL uses CMSG, DMSG, or EMSG switches instead of the older CS1-M or DS1-M.
The usable push force is 176.4 N at 0.5 MPa and 274.5 N at 0.7 MPa, with a maximum of about 28 kgf. The minimum operating pressure is 0.2 MPa because the air must overcome the internal return spring. The operating pressure range is 0.2-1.0 MPa.
