This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30CM 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 MSAL40X30CM
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X30CM 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30CM.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X30CM
The AirTAC MSAL40X30CM is a discontinued single-acting push, spring-return mini cylinder. Air extends the rod for work, while an internal spring retracts it to a fail-safe home on air loss. It delivers 539.9 N usable push force at 0.5 MPa and 791.1 N at 0.7 MPa. The exact drop-in replacement is the MSBL40X30CM, matching the 40 mm bore, 30 mm stroke, G1/4 port, and CM cover.
This SKU has no -S magnet, so it cannot take a position sensor. It uses a fixed rubber bumper for end-of-stroke damping. The older MSAL uses threaded covers and PT port threads; the MSBL40X30CM upgrade shifts to a riveted rolling-packed body. Never apply external load on the spring return stroke.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X30CM Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL40X30CM |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30CM |
| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30CM 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 MSAL40X30CM Is Used
Injection Mold Ejection
Ejects plastic parts from a mold using 539.9 N at 0.5 MPa, with the spring ensuring a fail-safe retracted home so the mold closes safely.
Sheet Metal Clamping
Holds light gauge sheet metal in a press brake jig; the CM round-end cover fits tight spaces, and the 791.1 N force at 0.7 MPa resists vibration.
Packaging Gate Divert
Pushes a mechanical diverter gate on a packaging line using one 3/2 valve, where the spring return guarantees the gate clears on air loss.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X30CM with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30CM
Replace this MSAL40X30CM with the drop-in MSBL40X30CM. Confirm the 40 mm bore, 30 mm stroke, G1/4 port, PT thread, and CM round-end cover. Because this SKU lacks the -S magnet, it cannot hold a sensor; the MSBL upgrade would use CMSG, DMSG, or EMSG switches if needed. Remember the 0.2 MPa minimum air pressure to beat the return spring.
To size either direction: stepping down to the 32 mm bore drops usable push to 317.7 N at 0.5 MPa, while stepping up is impossible as 40 mm is the largest mini bore. At 30 mm stroke, side-load risk is low, but ensure the M12x1.25 rod-end thread aligns true to prevent guide wear.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30CM (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30CM instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X30CM FAQ
Yes, the MSAL40X30CM is discontinued. The exact drop-in replacement is the MSBL40X30CM, matching the 40 mm bore, 30 mm stroke, G1/4 port, and CM cover. The MSBL upgrade uses a riveted rolling-packed body instead of threaded covers.
The usable push force is 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa. The maximum is 791.1 N. The minimum operating pressure is 0.2 MPa because the air must overcome the internal return spring to extend the rod.
