This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25SU 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 MSAL40X25SU
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X25SU is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø40mm bore and 25mm stroke, G1/4 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25SU.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X25SU
The AirTAC MSAL40X25SU is a discontinued single-acting push mini cylinder with a 40 mm bore and 25 mm stroke. Air extends the rod while an internal spring retracts it, providing a fail-safe retracted home on air loss. It delivers 539.9 N of usable push force at 0.5 MPa and 791.1 N at 0.7 MPa. The drop-in replacement is the MSBL40X25SU, matching the bore, stroke, G1/4 port, and U flat-end back cover.
This SKU includes the -S magnet, which pairs with the older CS1-M / DS1-M reed switches. The MSBL upgrade shifts to CMSG / DMSG / EMSG sensors and replaces the MSAL's threaded covers with a riveted rolling-packed body. End-of-stroke damping relies on a fixed rubber bumper, and the minimum operating pressure is 0.2 MPa to overcome the return spring. Apply no external load on the return stroke.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X25SU Technical Specifications

| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25SU carries the same single-acting ratings.
Usable Push Force (Ø40mm)
| Pressure | Push force (net of spring) |
|---|---|
| 0.5 MPa | 539.9 N |
| 0.7 MPa | 791.1 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 MSAL40X25SU Is Used
Injection Mold Ejection
Ejects small plastic parts from a mold using 539.9 N push at 0.5 MPa. The spring return guarantees the ejector pin retracts safely before the mold closes.
PCB Stencil Wiping
Presses a wiper blade down onto a solder paste stencil. The fixed rubber bumper absorbs the end-stroke impact, protecting the delicate mesh.
Packaging Flap Folding
Folds corrugated carton flaps on a packaging line. The fail-safe spring return drops the flap if air pressure drops, preventing machine jams.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X25SU with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25SU
To replace the MSAL40X25SU, install the MSBL40X25SU and confirm the 40 mm bore, 25 mm stroke, PT G1/4 port, and U flat-end back cover. Swap the -S magnet's CS1-M / DS1-M switches for CMSG / DMSG / EMSG sensors. Maintain at least 0.2 MPa air pressure to beat the return spring, and never apply external load on the return stroke.
For sizing flexibility, stepping down to the 32 mm bore yields 317.7 N push at 0.5 MPa, while stepping up is not possible as 40 mm is the largest in this mini family. With a 25 mm stroke on this 40 mm bore, side-load and rod-bending risks are minimal, but ensure rigid front-cover guide alignment.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25SU (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25SU instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X25SU FAQ
Yes, the MSAL40X25SU is discontinued. The exact drop-in replacement is the MSBL40X25SU, which matches the 40 mm bore, 25 mm stroke, G1/4 port, and U flat-end back cover. You will need to upgrade your sensors from the older CS1-M / DS1-M to the CMSG / DMSG / EMSG family.
The usable push force, already net of the return spring, is 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa. The minimum operating pressure is 0.2 MPa because the compressed air must overcome the internal return spring to extend the rod.
