This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X140CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X140CA 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 MSAL40X140CA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X140CA is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø40mm bore and 140mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X140CA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X140CA
The AirTAC MSAL40X140CA is a discontinued single-acting push cylinder with a 40 mm bore and 140 mm stroke. Air extends the rod to do work, while an internal spring retracts it to a fail-safe home when air is released. This CA pivot-cover version delivers a usable push force of 539.9 N at 0.5 MPa (791.1 N at 0.7 MPa), net of the return spring.
The exact drop-in replacement is the MSBL40X140CA, matching the bore, stroke, G1/4 port, and CA clevis mount. The MSAL features threaded covers and a fixed rubber bumper, whereas the MSBL upgrades to a riveted rolling-packed body. Note this SKU lacks the -S magnet, so it cannot accept a position sensor.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X140CA Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL40X140CA |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X140CA |
| Bore size | Ø40 mm |
| Stroke | 140 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X140CA 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 MSAL40X140CA Is Used
Stamping Press Ejection
Ejects formed sheet metal brackets from a stamping die. The 539.9 N push force at 0.5 MPa clears the part, and the spring return guarantees the ejector pin retracts before the next cycle.
Pivoting Gate Diversion
Arcs a heavy cardboard packaging diverter gate on a conveyor line. The CA clevis accommodates the swinging motion, while the fail-safe spring return pulls the gate back on air loss.
Plastic Mold Clamping
Holds injection mold halves closed during a low-pressure secondary operation. The 140 mm stroke reaches across the mold base, with the fixed rubber bumper absorbing the extend impact.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X140CA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X140CA
To replace this MSAL40X140CA, install the MSBL40X140CA. Verify your 3/2 valve supplies the 0.2 MPa minimum pressure required to overcome the return spring, and apply no external load on the non-powered return stroke. If you need a position sensor, you must step up to an -S MSBL model and switch from the legacy CS1-M/DS1-M switches to the modern CMSG/DMSG/EMSG family.
For sizing flexibility, stepping down to a 32 mm bore drops the 0.5 MPa push force to 317.7 N, while stepping up is unavailable as 40 mm is the largest in this series. Because this 140 mm stroke is long for a mini cylinder, ensure your CA clevis pin swings freely to prevent side-load rod bending.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X140CA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X140CA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X140CA FAQ
Yes, the MSAL40X140CA is discontinued. The exact drop-in replacement is the MSBL40X140CA, which matches the 40 mm bore, 140 mm stroke, G1/4 port, and CA clevis mount. The MSBL upgrades the body to a riveted rolling-packed design.
This single-acting push cylinder delivers 539.9 N of usable force at 0.5 MPa and 791.1 N at 0.7 MPa (roughly 80 kgf). It requires a minimum operating pressure of 0.2 MPa to overcome the internal return spring and extend the rod.
