This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL25X5U, 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 MSAL25X5U
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL25X5U 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X5U.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X5U
The AirTAC MSAL25X5U is a discontinued single-acting push-type mini cylinder with a 25mm bore and 5mm stroke. Air extends the rod while an internal spring retracts it, providing a fail-safe home position upon air loss. It yields a usable push force of 176.4 N at 0.5 MPa and 274.5 N at 0.7 MPa. The direct replacement is the MSBL25X5U, matching the bore, stroke, G1/8 port, and U back cover.
This SKU lacks the -S magnet and cannot accept a position sensor. The older MSAL uses threaded covers and CS1-M/DS1-M switches, whereas the MSBL upgrade features a riveted rolling-packed body and CMSG/DMSG/EMSG sensors. End-of-stroke damping relies on a fixed rubber bumper, not an adjustable cushion.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X5U Technical Specifications

| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X5U 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 MSAL25X5U Is Used
PCB Ejector Pins
Brief 5mm stroke pops populated circuit boards from test fixtures using 176.4 N at 0.5 MPa, with the spring safely retracting the pin during board loading.
Chip Tray Stops
Acts as a short physical barrier in semiconductor handling lines, extending to halt a tray and retracting out of the path on air release.
Small Part Sorting Gates
Diverts small plastic hardware in vibratory bowl feeders; the fail-safe spring-return design clears the path automatically if compressed air drops.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X5U with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X5U
To replace this MSAL25X5U with the MSBL25X5U, confirm the 25mm bore, 5mm stroke, PT G1/8 port, M10x1.25 rod thread, and the flat-end U back cover. Because this SKU has no -S magnet, it cannot hold a sensor; if you need position detection, step up to the MSBL25X5US and use CMSG/DMSG/EMSG switches. A 3/2 valve drives the push side, requiring a minimum 0.2 MPa to overcome the return spring. Never apply an external load on the spring return stroke. If sizing force, the 20mm bore pushes 106.8 N at 0.5 MPa, while the 32mm bore yields 317.7 N at 0.5 MPa.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X5U (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X5U instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X5U FAQ
Yes, the MSAL25X5U is discontinued. The direct replacement is the MSBL25X5U, matching the 25mm bore, 5mm stroke, G1/8 port, and U back cover. The MSBL upgrades the body to a riveted rolling-packed design.
The 25mm bore single-acting push force is 29.2 N at 0.2 MPa, 127.4 N at 0.4 MPa, 176.4 N at 0.5 MPa, and 274.5 N at 0.7 MPa (max). Operating pressure is 0.2-1.0 MPa; the 0.2 MPa minimum is required for air to overcome the return spring.
