This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X70U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X70U 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 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 drop-in 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 drop-in 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 |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| 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 exact drop-in 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.
