This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL40X125CMFA, 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 MSAL40X125CMFA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X125CMFA is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø40mm bore and 125mm 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 direct replacement is the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X125CMFA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X125CMFA
The AirTAC MSAL40X125CMFA is a discontinued single-acting push, spring-return mini cylinder. Air extends the 16mm rod for the 125mm work stroke, while an internal spring retracts it to a fail-safe home when air drops. This 40mm bore yields a usable push force of 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa. The direct replacement is the MSBL40X125CMFA, matching the G1/4 port, CM cover, and FA flange.
This SKU has no -S magnet and cannot take a position sensor. The original MSAL uses threaded covers and PT tapered port threads; the MSBL upgrade features a riveted rolling-packed body. End-of-stroke deceleration uses a fixed rubber bumper, not an adjustable cushion. On air loss, the spring drives the rod to its retracted rest, which is a defined home position, not a locked load.

| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X125CMFA 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 MSAL40X125CMFA Is Used
Stamping Press Ejection
Ejects small stamped metal parts from a die using 539.9 N of push force at 0.5 MPa, relying on the spring return to clear the tooling before the next cycle.
Packaging Flap Folding
Pushes cardboard flaps down during carton erecting, where the fail-safe spring retraction ensures the folder retracts out of the way if air pressure drops.
Pneumatic Gate Diversion
Actuates a diverter gate on a conveyor line, using the G1/4 port's high flow for rapid 125mm extension to route packages into packing lanes.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X125CMFA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X125CMFA
To replace this MSAL40X125CMFA with the MSBL40X125CMFA, verify the 40mm bore, 125mm stroke, G1/4 port, CM round-end cover, and FA flange stay identical. Because this SKU lacks the -S magnet, it cannot accept a sensor; if you need position detection, step up to an MSBL40X125SMFA which uses the modern CMSG/DMSG/EMSG switch family. Minimum operating pressure is 0.2 MPa to overcome the return spring.
For sizing flexibility, stepping down to the 32mm bore gives 317.7 N push at 0.5 MPa, while stepping up is not available as 40mm is the largest in this mini series. With a 125mm stroke on this compact body, minimize side loads to prevent rod-bending and premature seal wear. Never apply an external load on the spring return stroke.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X125CMFA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X125CMFA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X125CMFA FAQ
Yes, the MSAL40X125CMFA is discontinued. The direct replacement is the MSBL40X125CMFA, which matches the 40mm bore, 125mm stroke, G1/4 port, CM cover, and FA mounting. The MSBL upgrades the body to a riveted rolling-packed design while maintaining the same force class.
The usable push force (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, as the air supply must overcome the internal return spring to extend the rod.
