This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL25X70U, 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 MSAL25X70U
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL25X70U is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø25mm bore and 70mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X70U.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X70U
The AirTAC MSAL25X70U is a discontinued single-acting push, spring-return mini cylinder. Air extends the rod for the 70 mm work stroke, and an internal spring retracts it when air is released, providing a fail-safe retracted home on air loss. The direct replacement is the MSBL25X70U, matching the 25 mm bore, stroke, G1/8 port, and U flat-end back cover.
This 25 mm bore unit delivers 176.4 N of usable push force at 0.5 MPa and 274.5 N at 0.7 MPa (net of the return spring). It uses a fixed rubber bumper for end-of-stroke damping, as single-acting designs lack adjustable cushions. The original MSAL features threaded covers and no -S magnet, meaning this specific SKU cannot accept a position sensor. The modern MSBL replacement upgrades the body to a riveted rolling-packed design.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X70U Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL25X70U |

| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X70U |
| Bore size | Ø25 mm |
| Stroke | 70 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X70U 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 MSAL25X70U Is Used
PCB Router Ejection
Ejects routed printed circuit boards from a machining fixture using 176.4 N of push force at 0.5 MPa, with the spring return ensuring the arm clears the workspace on air loss.
Packaging Flap Fold
Folds minor carton flaps during a continuous packaging line, relying on the fixed rubber bumper to absorb the 70 mm stroke impact without bounce.
Textile Loom Diverter
Deflects yarn threads on a weaving loom; the single-acting 3/2 valve wiring keeps pneumatic control simple, and the U flat-end cover mounts flush against the machine frame.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X70U with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X70U
To replace the MSAL25X70U, specify the MSBL25X70U to retain the 25 mm bore, 70 mm stroke, PT G1/8 port, U flat-end back cover, and non-magnet configuration. Remember the minimum operating pressure is 0.2 MPa to overcome the return spring, and apply no external load on the return stroke. At 70 mm stroke on a mini bore, rod side-loads can cause bending; ensure rigid guiding.
If sizing force, step down to the 20 mm bore (106.8 N push at 0.5 MPa) for lighter tasks, or step up to the 32 mm bore (317.7 N push at 0.5 MPa) if you need more ejection power. The 25 mm bore provides 176.4 N at 0.5 MPa and 274.5 N at 0.7 MPa.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X70U (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X70U instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X70U FAQ
Yes, the MSAL25X70U is discontinued. The direct replacement is the AirTAC MSBL25X70U, which matches the 25 mm bore, 70 mm stroke, G1/8 port, and U back cover. The MSBL upgrades the body to a riveted rolling-packed design.
The usable push force is 176.4 N at 0.5 MPa and 274.5 N at 0.7 MPa. The minimum operating pressure is 0.2 MPa, which is required to overcome the internal return spring. This specific SKU lacks a -S magnet, so it cannot accept a position sensor.
