This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X150SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X150SCA 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 MSAL40X150SCA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X150SCA is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø40mm bore and 150mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X150SCA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X150SCA
The AirTAC MSAL40X150SCA is a discontinued 40mm bore, 150mm stroke single-acting push cylinder with a spring return. Air extends the rod, while the internal spring retracts it to a fail-safe home when pressure drops. It delivers a usable push force of 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa. The exact drop-in replacement is the MSBL40X150SCA, matching the bore, stroke, G1/4 port, and CA pivot cover.
This MSAL features a -S magnet compatible with older CS1-M and DS1-M reed switches; the MSBL upgrade uses CMSG, DMSG, or EMSG sensors. The legacy body uses threaded covers, whereas the modern MSBL features a riveted rolling-packed body. Both share a fixed rubber bumper for end-of-stroke damping, requiring no external air cushioning adjustments.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X150SCA Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL40X150SCA |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X150SCA |
| Bore size | Ø40 mm |
| Stroke | 150 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X150SCA 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 MSAL40X150SCA Is Used
Stamping Press Ejection
Ejects stamped metal blanks from a press die using 539.9 N of push force at 0.5 MPa, with the spring ensuring the arm safely retracts before the next cycle.
Welding Fixture Clamping
Holds a steel chassis tube in a robotic welding cell; the CA pivot accommodates slight arc misalignment while the spring returns the clamp on air loss.
Packaging Gate Diversion
Pushes cartons onto a secondary packaging belt using a 150mm stroke, relying on the fixed rubber bumper to absorb the impact at full extension.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X150SCA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X150SCA
To replace the MSAL40X150SCA, install the MSBL40X150SCA. Confirm the 40mm bore, 150mm stroke, M12x1.25 rod-end thread, PT G1/4 port, CA pivot back cover, and the sensor family change from CS1-M/DS1-M to CMSG/DMSG/EMSG. Maintain a minimum 0.2 MPa operating pressure to overcome the return spring, and apply no external load on the spring return stroke.
At 150mm stroke on a 40mm bore, prevent rod bending by ensuring strict alignment and minimizing side loads. If 539.9 N push at 0.5 MPa is insufficient, step up to the next available bore. If you need less force, step down to a 32mm bore providing 317.7 N at 0.5 MPa.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X150SCA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X150SCA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X150SCA FAQ
Yes, the MSAL40X150SCA is discontinued. The exact drop-in replacement is the MSBL40X150SCA, which matches the 40mm bore, 150mm stroke, CA pivot cover, and G1/4 port. You only need to update your sensors from the older CS1-M/DS1-M switches to CMSG/DMSG/EMSG models.
The usable push force is 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa, equating to roughly 80.6 kgf at maximum pressure. Because it is single-acting, the minimum working pressure is 0.2 MPa to ensure air overcomes the internal return spring.
