This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25SCA 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 MSAL40X25SCA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X25SCA 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25SCA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X25SCA
The AirTAC MSAL40X25SCA is a discontinued single-acting push cylinder with a 40mm bore and 25mm stroke. Air extends the rod for the work stroke, while an internal spring retracts it when air is released, 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 direct drop-in replacement is the MSBL40X25SCA, which matches the G1/4 port, CA pivot clevis, and force class exactly.
This SKU includes the -S magnet for position sensing with older CS1-M or DS1-M reed switches; the MSBL replacement upgrades this to CMSG, DMSG, or EMSG sensors. The MSAL features threaded covers and a fixed rubber bumper, whereas the modern MSBL uses a riveted rolling-packed body. A minimum working pressure of 0.2 MPa is required to overcome the return spring, and you must apply no external load on the spring return stroke.

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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25SCA 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 MSAL40X25SCA Is Used
Stamping Press Ejection
Ejects small stamped metal parts from a die using 539.9 N of push force at 0.5 MPa. The spring return guarantees the ejector pin retracts clear of the tool before the next cycle.
Packaging Flap Folding
Pushes cardboard carton flaps closed on a packaging line. The CA clevis allows the cylinder to swing naturally as the flap angle changes during the 25mm stroke.
Woodworking Gate Diversion
Actuates a diverter gate to route wood offcuts on a conveyor. Air loss triggers the spring return, pulling the gate to a fail-safe home position to prevent material jams.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X25SCA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25SCA
To replace this MSAL40X25SCA, use the drop-in MSBL40X25SCA. Confirm your 40mm bore, 25mm stroke, G1/4 port, PT thread, CA back cover, and mounting. The -S magnet means your old CS1-M/DS1-M switches must change to the CMSG/DMSG/EMSG family on the new body. Remember the 0.2 MPa minimum air pressure and never apply external load on the return stroke. If sizing down, the 32mm bore neighbor yields 317.7 N at 0.5 MPa. If stepping up, 40mm is the largest MAL series bore, so this is your maximum force option. For this 25mm stroke on a 40mm bore, side-load and rod-bending risks are minimal, but always ensure rigid front mounting.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25SCA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25SCA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X25SCA FAQ
Yes, the MSAL40X25SCA is discontinued. The exact drop-in replacement is the MSBL40X25SCA, matching the 40mm bore, 25mm stroke, CA clevis, G1/4 port, and force class. You only need to update your sensors from the older CS1-M/DS1-M switches to the CMSG/DMSG/EMSG family used on the MSBL.
The 40mm bore single-acting push force is 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa. It requires a minimum operating pressure of 0.2 MPa to overcome the internal return spring. The cylinder uses a fixed rubber bumper for end-of-stroke damping and cannot hold a load mid-stroke without an external device.
