This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30SCM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30SCM 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 MSAL40X30SCM
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X30SCM 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30SCM.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X30SCM
The AirTAC MSAL40X30SCM 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 40 mm bore 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 MSBL40X30SCM, matching the 30 mm stroke, G1/4 port, and CM round-end cover.
This SKU includes the -S magnet for position sensing. On this legacy body, the magnet uses older CS1-M or DS1-M switches; the MSBL replacement upgrades to CMSG, DMSG, or EMSG sensors. The MSAL features threaded covers, whereas the current MSBL uses a riveted rolling-packed body. End-of-stroke deceleration relies on a fixed rubber bumper, as no adjustable cushion exists on this type. Apply no external load on the spring return stroke to prevent rod damage.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X30SCM Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL40X30SCM |

| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30SCM 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 MSAL40X30SCM Is Used
Sheet Metal Stamping Ejector
Pushes formed aluminum panels out of a stamping die using 539.9 N at 0.5 MPa, with the spring safely retracting the rod clear of the tool.
Injection Mold Parting Gate
Actuates a diverter gate to route plastic parts down a chute; air loss drops the gate to a fail-safe closed rest via the internal spring.
PCB Router Clamping Jig
Holds a printed circuit board panel against a router fixture, using the -S magnet with a CS1-M switch to confirm clamp extension before cutting.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X30SCM with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30SCM
To replace the MSAL40X30SCM, order the MSBL40X30SCM. Confirm the 40 mm bore, 30 mm stroke, G1/4 port, PT thread, CM round-end cover, and -S magnet. Remember that the sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG on the new body. Operating pressure must remain at least 0.2 MPa to overcome the return spring.
If sizing this 40 mm bore, step down to the 32 mm bore for lighter tasks, which provides 317.7 N of push force at 0.5 MPa. Step up is not available as 40 mm is the largest standard size in this mini series. The 30 mm stroke is short, but always ensure rigid mounting to prevent side-load and rod-bending stress.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30SCM (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30SCM instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X30SCM FAQ
Yes, the MSAL40X30SCM is discontinued. The exact drop-in replacement is the MSBL40X30SCM, which matches the 40 mm bore, 30 mm stroke, G1/4 port, and CM cover. You will need to upgrade your position sensors, as the MSBL uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M.
This single-acting push cylinder requires a minimum of 0.2 MPa to overcome the return spring. The usable push force is 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa. The maximum push force is approximately 80.7 kgf at 0.7 MPa.
