This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X15SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X15SU 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 MSAL40X15SU
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X15SU is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø40mm bore and 15mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X15SU.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X15SU
The AirTAC MSAL40X15SU is a discontinued single-acting push, spring-return mini cylinder. Air extends the 16mm rod to deliver 539.9 N of usable push force at 0.5 MPa, while an internal spring retracts it for a fail-safe home on air loss. The exact drop-in replacement is the MSBL40X15SU, matching the 40mm bore, 15mm stroke, G1/4 port, and U flat-end back cover.
This SKU includes the -S magnet for position sensing, using the older CS1-M or DS1-M switches. The MSBL upgrade switches to CMSG, DMSG, or EMSG sensors and replaces the MSAL's threaded covers with a riveted rolling-packed body. The fixed rubber bumper absorbs end-of-stroke impact, and a minimum 0.2 MPa air pressure is required to overcome the return spring.

| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X15SU 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 MSAL40X15SU Is Used
Injection Mold Ejector
Ejects small plastic parts from injection molds using 539.9 N push force at 0.5 MPa, with the spring return ensuring the rod clears the mold plate during air loss.
Stator Lamination Press
Performs short 15mm stamping strokes on electric motor stator laminations, relying on the fixed rubber bumper to absorb the high-frequency end impacts.
Packaging Flap Deflector
Pushes corrugated cardboard flaps clear of sealing jaws on cartoners, where the fail-safe spring return guarantees the deflector retracts before the next box passes.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X15SU with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X15SU
To replace this MSAL40X15SU, order the MSBL40X15SU. Confirm the 40mm bore, 15mm stroke, G1/4 port, PT thread, U flat-end back cover, and -S magnet. Note the sensor family change from CS1-M/DS1-M to CMSG/DMSG/EMSG. Maintain the 0.2 MPa minimum pressure and apply no external load on the return stroke.
For sizing flexibility, step down to the 32mm bore (317.7 N push at 0.5 MPa) for lighter ejection tasks, or step up if unavailable. At 15mm stroke, side-load and rod-bending risks are minimal, but ensure axial load alignment to protect the 16mm rod and front-cover guide.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X15SU (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X15SU instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X15SU FAQ
Yes, the MSAL40X15SU is discontinued. The exact drop-in replacement is the MSBL40X15SU. It matches the 40mm bore, 15mm stroke, G1/4 port, and U flat-end back cover. The MSBL also upgrades the body to a riveted rolling-packed design and uses CMSG/DMSG/EMSG sensors instead of the older CS1-M/DS1-M switches.
The single-acting push force is net of the return spring. It delivers 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa. The maximum push force is 791.1 N (about 80.6 kgf). A minimum operating pressure of 0.2 MPa is required to overcome the internal return spring and extend the rod.
