This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL25X25U, 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 MSAL25X25U
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL25X25U 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X25U.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X25U
The AirTAC MSAL25X25U is a discontinued single-acting push, spring-return mini cylinder. Air extends the rod for the work stroke, while an internal spring retracts it, providing a fail-safe retracted home on air loss. It delivers a usable push force of 176.4 N at 0.5 MPa (274.5 N at 0.7 MPa) through a 25 mm bore. The direct replacement is the MSBL25X25U, which shares the same bore, stroke, U back cover, and force class.
This SKU lacks the -S magnet, so it cannot accept a position sensor. The original MSAL uses threaded covers and a PT port, whereas the MSBL upgrade features a riveted rolling-packed body. Both share a fixed rubber bumper for end-of-stroke damping. Remember that the return spring only manages the rod's mass; apply no external load on the return stroke.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X25U Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL25X25U |

| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X25U 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 MSAL25X25U Is Used
PCB Ejector Pins
Pushes finished circuit boards out of an assembly fixture with 176.4 N at 0.5 MPa, relying on the spring return to retract the pin safely for the next panel load.
Packaging Flap Deflector
Extends to hold a cardboard carton flap clear during product drop, then springs back to its fail-safe home when the 3/2 valve exhausts.
Textile Loom Tensioner
Applies 274.5 N of push force at 0.7 MPa to shift a yarn guide rail, with the spring ensuring the mechanism rests at a defined retracted position during air loss.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X25U with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X25U
To replace the MSAL25X25U with the MSBL25X25U, confirm the 25 mm bore, 25 mm stroke, G1/8 port, PT thread, and the flat-end U back cover. Because this SKU lacks the -S magnet, no sensor migration is needed. Ensure your 3/2 valve supplies at least the 0.2 MPa minimum operating pressure to overcome the return spring. If sizing down, the 20 mm bore offers 106.8 N at 0.5 MPa; if stepping up, the 32 mm bore provides 317.7 N at 0.5 MPa. For this 25 mm stroke, side-load risks are minimal, but always maintain rod alignment to prevent guide wear.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X25U (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X25U instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X25U FAQ
Yes, the MSAL25X25U is discontinued. The direct replacement is the MSBL25X25U, which matches the 25 mm bore, 25 mm stroke, G1/8 port, and U back cover. The MSBL upgrade changes the body construction to a riveted rolling-packed design.
The 25 mm bore single-acting push cylinder requires a minimum operating pressure of 0.2 MPa. It delivers a usable push force of 176.4 N at 0.5 MPa and 274.5 N at 0.7 MPa. The maximum operating pressure is 1.0 MPa, with speeds of 50-800 mm/s.
