This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X80SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X80SU 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 MSAL40X80SU
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X80SU 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X80SU.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X80SU
The AirTAC MSAL40X80SU is a discontinued single-acting push mini cylinder with an 80mm stroke. Air extends the rod for the work cycle, and an internal spring retracts it to a fail-safe home when air is removed. As the largest standard bore in this series, it 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 MSBL40X80SU, matching the 40mm bore, stroke, G1/4 port, and U flat-end back cover.
This MSAL40X80SU SKU includes the -S magnet for position sensing, which uses the older CS1-M and DS1-M reed switches. When upgrading to the MSBL40X80SU, the sensor family changes to the CMSG, DMSG, or EMSG series. The original MSAL features threaded covers and a fixed rubber bumper for end-of-stroke damping, while the current MSBL replacement uses a riveted rolling-packed body. Always operate above the 0.2 MPa minimum pressure to overcome the return spring, and apply no external load on the return stroke.

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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X80SU 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 MSAL40X80SU Is Used
Stamping Press Ejection
Ejects small stamped metal parts from a die using 539.9 N of push force at 0.5 MPa. The spring return safely retracts the rod when air is lost, preventing press jams.
PCB Router Gate
Actuates a routing gate on a circuit board depaneling line. The G1/4 port provides high flow for rapid 80mm extension, while the U flat-end cover mounts rigidly to the frame.
Plastic Mold Blow-off
Pushes a blow-off air nozzle against a plastic injection mold. The fixed rubber bumper absorbs the 791.1 N impact force at 0.7 MPa without requiring manual adjustment.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X80SU with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X80SU
To replace the MSAL40X80SU, order the MSBL40X80SU. Confirm the 40mm bore, 80mm stroke, G1/4 port, PT thread form, U flat-end back cover, and the -S magnet. Remember the sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG. The 0.2 MPa minimum operating pressure is required to beat the return spring. If sizing down, the 32mm bore yields 317.7 N at 0.5 MPa; if stepping up, this 40mm bore is the largest available in this mini series, providing 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa. For this 80mm stroke on a small bore, ensure adequate guide support to prevent rod bending and side-load damage.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X80SU (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X80SU instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X80SU FAQ
Yes, the MSAL40X80SU is discontinued. The exact drop-in replacement is the MSBL40X80SU, which matches the 40mm bore, 80mm stroke, G1/4 port, and U flat-end back cover. You will need to update your position sensors, as the MSAL -S magnet uses CS1-M/DS1-M switches, while the MSBL uses CMSG/DMSG/EMSG switches.
The 40mm bore single-acting push force is 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa. The maximum equivalent is roughly 80.7 kgf. It requires a minimum operating pressure of 0.2 MPa to overcome the internal return spring, which drives the rod to its fail-safe retracted home on air loss.
