This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X20SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X20SCA 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 MSAL40X20SCA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X20SCA is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø40mm bore and 20mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X20SCA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X20SCA
The AirTAC MSAL40X20SCA 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. Bore 40 mm yields 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 MSBL40X20SCA, matching the bore, stroke, port, and force.
This SKU includes the CA pivot back cover, which swings on a pin to accommodate arcing loads. The -S magnet works with older CS1-M / DS1-M switches; the MSBL replacement upgrades to CMSG / DMSG / EMSG sensors and a riveted rolling-packed body. It uses a G1/4 port, an M12x1.25 rod-end thread, and fixed rubber bumpers instead of adjustable cushions. Apply no external load on the spring return stroke.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X20SCA Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL40X20SCA |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X20SCA |
| Bore size | Ø40 mm |
| Stroke | 20 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X20SCA 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 MSAL40X20SCA Is Used
Stamping Press Ejector
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 die before the next cycle.
Woodworking Clamp
Holds a wooden workpiece against a router fence during machining, with the fail-safe home releasing the clamp automatically if shop air drops.
Packaging Gate Diverter
Pushes a mechanical diverter gate to route cardboard cartons, where the CA pivot back cover accommodates the slight arcing load of the swing mechanism.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X20SCA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X20SCA
To replace this MSAL40X20SCA, order the MSBL40X20SCA. Confirm the 40 mm bore, 20 mm stroke, G1/4 port, PT thread, CA pivot back cover, and the sensor family change from CS1-M / DS1-M to CMSG / DMSG / EMSG. Maintain the 0.2 MPa minimum air pressure to beat the return spring, and never apply external load on the return stroke.
For sizing, stepping down to the 32 mm bore drops usable push to 317.7 N at 0.5 MPa, while stepping up is unavailable as 40 mm is the largest mini bore. The 20 mm stroke resists rod-bending well, but ensure side loads are minimized.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X20SCA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X20SCA instead of this discontinued model.
