This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL40X15SCM, 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 MSAL40X15SCM
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X15SCM is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø40mm bore and 15mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X15SCM.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X15SCM
The AirTAC MSAL40X15SCM is a discontinued single-acting push, spring-return mini cylinder. Air extends the rod for the work stroke, while an internal spring retracts it to a fail-safe home when air is released. This 40mm bore delivers 539.9N of usable push force at 0.5MPa and 791.1N at 0.7MPa. The direct replacement is the MSBL40X15SCM, retaining the same bore, 15mm stroke, G1/4 port, and CM round-end cover.
This MSAL features a -S magnet for position sensing using the older CS1-M or DS1-M switches; the MSBL replacement upgrades this to CMSG, DMSG, or EMSG sensors. The MSAL body uses threaded covers, whereas the current MSBL utilizes a riveted rolling-packed body. End-of-stroke deceleration is handled by a fixed rubber bumper, as no adjustable cushion exists on this single-acting series.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X15SCM Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL40X15SCM |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X15SCM |
| Bore size | Ø40 mm |
| Stroke | 15 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X15SCM 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 MSAL40X15SCM Is Used
PCB Edge Connector Seating
Delivers 539.9N at 0.5MPa to press gold-edge connectors flush onto printed circuit boards, using the short 15mm stroke for rapid, precise insertion without over-travel.
Aluminum Extrusion End-Capping
Pushes plastic end caps into aluminum extrusion profiles on an assembly line, relying on the spring return to instantly retract and clear the part path on air loss.
Packaging Flap Deflection
Extends to briefly hold a cardboard carton flap open during automated product insertion, where the fail-safe retracted home ensures the packaging line jams clear safely.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X15SCM with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X15SCM
To replace this MSAL40X15SCM, specify the MSBL40X15SCM. Confirm the 40mm bore, 15mm stroke, PT G1/4 port, M12x1.25 rod-end thread, CM round-end back cover, and the -S magnet (noting the sensor family change to CMSG/DMSG/EMSG). Maintain the 0.2MPa minimum operating pressure required to overcome the return spring, and apply NO external load on the spring return stroke.
If sizing force, step down to a 32mm bore for 317.7N at 0.5MPa, or step up if you need more power (40mm is the largest MAL mini bore). The 15mm stroke is highly compact, keeping rod-bending side-load risks low, but always verify rigid alignment for the 16mm carbon-steel rod.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X15SCM (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X15SCM instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X15SCM FAQ
Yes, the MSAL40X15SCM is discontinued. The direct replacement is the MSBL40X15SCM, matching the 40mm bore, 15mm stroke, G1/4 port, and CM mounting. You will need to upgrade your position sensors, as the MSAL -S magnet uses older CS1-M/DS1-M switches while the MSBL uses CMSG/DMSG/EMSG switches.
The usable single-acting push force (already net of the return spring) is 539.9N at 0.5MPa and 791.1N at 0.7MPa, with a maximum of roughly 80.7 kgf. The operating pressure range is 0.2-1.0 MPa; a 0.2MPa minimum is required because the air pressure must overcome the internal return spring to extend the rod.
