This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL40X30CM, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 direct 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 direct 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 direct replacement 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 direct 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.
