This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30SCA 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 MSAL40X30SCA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X30SCA is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø40mm bore and 30mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30SCA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X30SCA
The AirTAC MSAL40X30SCA is a discontinued 40mm single-acting push cylinder with a 30mm stroke. Air extends the rod while an internal spring retracts it, providing a fail-safe retracted home. It delivers 539.9 N of usable push force at 0.5 MPa. The exact drop-in replacement is the MSBL40X30SCA, matching the bore, stroke, G1/4 port, and CA clevis.
This SKU includes the -S magnet for position sensing. The MSAL uses older CS1-M or DS1-M reed switches, while the MSBL upgrade uses CMSG, DMSG, or EMSG sensors. The MSAL features threaded covers, whereas the MSBL uses a riveted rolling-packed body. Both share a fixed rubber bumper, as no adjustable cushion exists on this single-acting type.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X30SCA Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL40X30SCA |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30SCA |
| Bore size | Ø40 mm |
| Stroke | 30 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30SCA 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 MSAL40X30SCA Is Used
Stamping Press Ejection
Ejects small stamped metal parts from a die using 539.9 N at 0.5 MPa, relying on the spring return to safely retract the pin if air pressure drops.
Pivoted Arc Gate
Uses the CA clevis to swing a heavy diverter gate on a packaging line, with the 40mm bore providing the force needed to overcome friction.
Circuit Board Clamping
Pushes a hold-down fixture against PCB routing decks; the fixed rubber bumper softens the 30mm stroke impact without needing adjustment.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X30SCA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30SCA
To replace this MSAL, install the MSBL40X30SCA. Confirm the 40mm bore, 30mm stroke, G1/4 port, PT thread, CA pivot clevis, and the sensor family change from CS1-M/DS1-M to CMSG/DMSG/EMSG. Maintain the 0.2 MPa minimum working pressure so air can overcome the return spring, and apply no external load on the spring return stroke.
If stepping down, the 32mm bore yields 317.7 N at 0.5 MPa. If stepping up, there is no larger standard MAL size, so the 40mm at 791.1 N (0.7 MPa) is your maximum push force here. At 30mm stroke, side-load risks are low, but always ensure rigid rod-end alignment to prevent guide wear.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30SCA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30SCA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X30SCA FAQ
Yes, the MSAL40X30SCA is discontinued. The exact drop-in replacement is the MSBL40X30SCA, which matches the 40mm bore, 30mm stroke, G1/4 port, and CA clevis. You only need to update your sensors from the older CS1-M/DS1-M to the CMSG/DMSG/EMSG family.
The 40mm bore provides a usable push force of 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa (equivalent to about 80 kgf). Because the internal spring opposes the air stroke, the minimum working pressure is 0.2 MPa to ensure the air can extend the rod.
