This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X80U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X80U 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 MSAL40X80U
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X80U is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø40mm bore and 80mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X80U.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X80U
The AirTAC MSAL40X80U is a discontinued single-acting push, spring-return mini cylinder. Air extends the 16 mm rod for the 80 mm work stroke, while an internal spring retracts it to a fail-safe home when air is removed. This 40 mm bore model uses a G1/4 port and a U-style flat-end back cover. It delivers a usable push force of 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa (already net of the opposing spring).
The exact drop-in replacement is the MSBL40X80U, matching the bore, stroke, force, port, and U-cover. Upgrading brings a riveted rolling-packed body instead of the older MSAL threaded covers. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor; if sensing is needed on the replacement, specify an MSBL40X80US to use modern CMSG, DMSG, or EMSG switches instead of the legacy CS1-M or DS1-M.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X80U Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL40X80U |

| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X80U |
| Bore size | Ø40 mm |
| Stroke | 80 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X80U 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 MSAL40X80U Is Used
Stamping Press Ejector
Ejects stamped sheet metal parts from a die using 539.9 N of push at 0.5 MPa, with the spring ensuring the retracted home position clears the next blank.
Woodworking Gate Deflector
Pushes a flap to divert cut lumber down a sorting chute; the fail-safe spring return opens the gate on air loss to prevent machine jams.
Bearing Press Fit
Presses small bearings into housings using the 791.1 N available at 0.7 MPa, relying on the fixed rubber bumper to absorb the end-of-stroke impact.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X80U with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X80U
Replace this MSAL40X80U with the MSBL40X80U. Confirm the 40 mm bore, 80 mm stroke, G1/4 port, PT thread, and U flat-end back cover. Remember the 0.2 MPa minimum operating pressure required for air to beat the return spring, and apply NO external load on the unpowered return stroke. With an 80 mm stroke on this small bore, watch for rod-bending side loads and guide the load.
To size either direction: step down to a 32 mm bore for 317.7 N push at 0.5 MPa, or step up to a larger double-acting MAL if you need powered retraction, as 40 mm is the largest single-acting MSAL bore.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X80U (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X80U instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X80U FAQ
Yes, the MSAL40X80U is discontinued. The exact drop-in replacement is the MSBL40X80U, which matches the 40 mm bore, 80 mm stroke, G1/4 port, and U flat-end back cover. The MSBL upgrades the body to a riveted rolling-packed design.
This single-acting push cylinder provides a usable force of 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa (net of the return spring). The minimum operating pressure is 0.2 MPa, required for the air to overcome the internal spring. The maximum push force is 791.1 N (about 80.6 kgf).
