This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X15U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X15U in place of this model. 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 MSAL25X15U
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL25X15U is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø25mm bore and 15mm 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 drop-in replacement is the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X15U.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X15U
The AirTAC MSAL25X15U is a discontinued single-acting push cylinder with a 25mm bore and 15mm stroke. 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 and 274.5 N at 0.7 MPa. The exact drop-in replacement is the MSBL25X15U, matching the bore, stroke, G1/8 port, and U flat-end back cover.
This SKU lacks the -S magnet option, so it cannot accept a position sensor. As an upgrade path, the MSAL features threaded covers and uses older CS1-M or DS1-M switches, whereas the modern MSBL replacement features a riveted rolling-packed body and uses CMSG, DMSG, or EMSG sensors. The fixed rubber bumper absorbs end-of-stroke impact without adjustable cushioning.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X15U Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL25X15U |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X15U |
| Bore size | Ø25 mm |
| Stroke | 15 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X15U 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 MSAL25X15U Is Used
PCB Ejector Pins
Uses the 176.4 N push force at 0.5 MPa to eject populated circuit boards from a test fixture, relying on the spring return to clear the bay on air loss.
Packaging Flap Folder
Folds small carton flaps on a packaging line where the 15mm stroke is sufficient, and the fail-safe retracted home prevents jamming during line stoppages.
Bottle Sorting Gate
Acts as a diverter gate for small plastic bottles, using the 274.5 N force at 0.7 MPa to push items into a rejection chute before retracting safely.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X15U with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X15U
Replace this MSAL25X15U directly with the MSBL25X15U, confirming the 25mm bore, 15mm stroke, PT G1/8 port, U flat-end back cover, and lack of magnet. Because this is a single-acting push cylinder, ensure your air supply meets the 0.2 MPa minimum to overcome the return spring, and never apply an external load on the spring return stroke. If sizing down, the 20mm bore offers 106.8 N at 0.5 MPa; if stepping up, the 32mm bore provides 317.7 N at 0.5 MPa. Even at 15mm stroke, keep the rod perfectly aligned to prevent side-load wear on the front-cover guide.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X15U (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X15U instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X15U FAQ
Yes, the MSAL25X15U is discontinued. The exact drop-in replacement is the MSBL25X15U, which matches the 25mm bore, 15mm stroke, G1/8 port, and U flat-end back cover.
The usable push force is 176.4 N at 0.5 MPa and 274.5 N at 0.7 MPa. It requires a minimum operating pressure of 0.2 MPa to overcome the internal return spring. This SKU has no magnet and cannot take a sensor.
