This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL25X30U, 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 MSAL25X30U
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL25X30U is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø25mm bore and 30mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X30U.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X30U
The AirTAC MSAL25X30U is a discontinued single-acting push, spring-return mini cylinder. Air extends the rod for the 30 mm work stroke, and an internal spring retracts it to a fail-safe home when air is released. It delivers a usable push force of 176.4 N at 0.5 MPa. The direct replacement is the MSBL25X30U, sharing the 25 mm bore, stroke, port, and U back cover.
This SKU has no -S magnet and cannot take a position sensor. The MSAL uses older CS1-M / DS1-M switches on magnetized variants, while the MSBL replacement uses CMSG / DMSG / EMSG sensors. The MSAL features threaded covers, whereas the MSBL upgrade uses a riveted rolling-packed body. Both use a fixed rubber bumper, meaning there is no adjustable cushion.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X30U Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL25X30U |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X30U |
| Bore size | Ø25 mm |
| Stroke | 30 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X30U 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 MSAL25X30U Is Used
PCB Ejector Gate
Pushes a thin PCB out of an SMT line fixture with 176.4 N at 0.5 MPa; the spring safely retracts the rod clear of the conveyor when air drops.
Carton Flap Tamp
Tamps a minor carton flap down during a packaging case sealer cycle, using the fail-safe spring return to lift the arm out of the product path.
Stamping Pin Press
Drives a 10 mm rod pin to stamp a 2D barcode on an aluminum extrusion, relying on the fixed rubber bumper to absorb the 30 mm stroke impact.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X30U with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X30U
To replace the MSAL25X30U, order the MSBL25X30U. Confirm the 25 mm bore, 30 mm stroke, G1/8 port, PT thread, and U flat-end back cover. Because this SKU lacks the -S magnet, it cannot hold a sensor; if you need position detection, step up to an MSBL variant with the S suffix and use CMSG / DMSG / EMSG switches. Minimum working pressure is 0.2 MPa to overcome the return spring, and you must apply no external load on the return stroke.
For sizing, if 176.4 N at 0.5 MPa is too much, step down to the 20 mm bore (106.8 N at 0.5 MPa). If you need more force, step up to the 32 mm bore (317.7 N at 0.5 MPa). For this 30 mm stroke, side-load and rod-bending risks are minimal.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X30U (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X30U instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X30U FAQ
Yes, the MSAL25X30U is discontinued. The direct replacement is the MSBL25X30U. It matches the 25 mm bore, 30 mm stroke, G1/8 port, and U back cover. The MSBL upgrades the body to a riveted rolling-packed design and uses CMSG / DMSG / EMSG sensors if you add the -S magnet option.
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 because the air pressure must overcome the internal return spring to extend the rod.
