This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25SCM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25SCM 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 MSAL40X25SCM
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X25SCM 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25SCM.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X25SCM
The AirTAC MSAL40X25SCM is a discontinued single-acting push cylinder. Air extends the 16 mm rod, while an internal spring retracts it to a fail-safe home. 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 MSBL40X25SCM, matching the 40 mm bore, 25 mm stroke, G1/4 port, and CM mounting.
This MSAL features a -S magnet compatible with older CS1-M and DS1-M reed switches. The modern MSBL replacement upgrades you to CMSG, DMSG, or EMSG sensors and uses a riveted rolling-packed body instead of the MSAL's threaded covers. Both generations use a fixed rubber bumper for end-of-stroke damping, meaning there is no adjustable cushion.

| Stroke | 25 mm |
| Acting type | Single acting, push (spring return) |
| Port size | G1/4 |
| Rod thread | M12×1.25 |
| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25SCM 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 MSAL40X25SCM Is Used
PCB Router Ejection
Uses the 539.9 N push force at 0.5 MPa to positively eject cut printed circuit boards from a router fixture. The spring return ensures the ejector retracts clear of the spindle, even on sudden air loss.
Stamping Press Feed
Pushes a metal strip forward into a mechanical stamping press. The fail-safe spring return pulls the feed finger back to home, preventing double-feeding if the air supply drops.
Casting Mold Gate
Acts as a diverter gate at a die-casting machine outlet. The CM round-end mount and 25 mm stroke provide a fast, short pivot to sort good parts from flash.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X25SCM with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25SCM
To replace the MSAL40X25SCM with the MSBL40X25SCM, confirm the 40 mm bore, 25 mm stroke, PT G1/4 port, M12x1.25 rod-end thread, and CM round-end back cover. Note the sensor family change: your old CS1-M or DS1-M switches will not fit the MSBL, requiring CMSG, DMSG, or EMSG sensors. Minimum operating pressure is 0.2 MPa to overcome the return spring.
If you need less force, step down to the 32 mm bore, which provides 317.7 N at 0.5 MPa. If you need more power, note that 40 mm is the largest standard MSAL size. Because the 25 mm stroke is very short, keep side-load strictly controlled to prevent rod-bending and premature seal wear. Never apply an external load on the unpowered spring return stroke.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25SCM (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25SCM instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X25SCM FAQ
Yes, the MSAL40X25SCM is discontinued. The exact drop-in replacement is the MSBL40X25SCM. It matches the 40 mm bore, 25 mm stroke, G1/4 port, and CM mounting. You will need to upgrade your sensors from the old CS1-M or DS1-M to the modern CMSG, DMSG, or EMSG switches.
The usable push force 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. The cylinder provides a fail-safe retracted home on air loss, but it cannot hold a load mid-stroke without an external locking device.
