This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X15U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X15U 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 MSAL40X15U
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X15U 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X15U.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X15U
The AirTAC MSAL40X15U is a discontinued single-acting push mini cylinder with a 40 mm bore and 15 mm stroke. Air extends the rod for the work stroke, while an internal spring retracts it when air is released, providing a fail-safe retracted home position upon air loss. This specific SKU delivers a usable push force of 539.9 N at 0.5 MPa (791.1 N at 0.7 MPa) and requires a minimum operating pressure of 0.2 MPa to overcome the return spring. The exact drop-in replacement is the MSBL40X15U, which matches the bore, stroke, force class, G1/4 port, and flat-end U mounting.
This MSAL40X15U unit features a fixed rubber bumper for end-of-stroke damping (no adjustable cushion) and a 16 mm hard-chrome carbon steel rod with an M12x1.25 rod-end thread. Because this configuration lacks the -S magnet option, it cannot accept a position sensor. As an upgrade path, the MSBL replacement shifts from the older MSAL threaded covers to a riveted rolling-packed body, and if a sensor were needed on the MSBL, it would use the newer CMSG/DMSG/EMSG switches rather than the legacy CS1-M/DS1-M family. Apply no external load on the spring return stroke to prevent mechanical damage.

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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X15U 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 MSAL40X15U Is Used
PCB Router Ejector
Deploys a short 15 mm stroke to push cut printed circuit boards from a routing machine fixture, yielding to the spring return when the 3/2 valve vents for fail-safe retraction.
Stamping Press Feed Gate
Actuates a heavy-duty material stop gate in a metal stamping line, using the 539.9 N at 0.5 MPa to positively index thick steel blanks before the press cycles.
Bearing Seating Press
Applies a brief 791.1 N push at 0.7 MPa to lightly seat small bearings into housings on an assembly carousel, with the fixed rubber bumper absorbing the metal-to-metal impact.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X15U with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X15U
To replace the MSAL40X15U, install the MSBL40X15U as a direct drop-in. Confirm the 40 mm bore, 15 mm stroke, G1/4 port, PT thread form, and flat-end U back cover. Since this MSAL SKU has no -S magnet, it cannot take a sensor; if your machine now requires position feedback, specify an MSBL40X15US and migrate to CMSG/DMSG/EMSG switches. Remember the 0.2 MPa minimum operating pressure and never apply external load on the spring return stroke.
For sizing flexibility, if 539.9 N of push at 0.5 MPa is excessive, step down to the 32 mm bore which yields 317.7 N at the same pressure. If you need more force, note that 40 mm is the largest standard bore in this mini series, so exceeding 791.1 N at 0.7 MPa requires migrating to a larger ISO profile cylinder family.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X15U (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X15U instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X15U FAQ
Yes, the MSAL40X15U is discontinued. The exact drop-in replacement is the MSBL40X15U, which shares the same 40 mm bore, 15 mm stroke, single-acting push function, G1/4 port, and flat-end U back cover. The MSBL upgrades the body to a riveted rolling-packed design instead of threaded covers.
The usable push force, already net of the return spring, is 163.1 N at 0.2 MPa, 414.3 N at 0.4 MPa, 539.9 N at 0.5 MPa, 665.5 N at 0.6 MPa, and 791.1 N at 0.7 MPa (max 80.6 kgf). It requires a minimum operating pressure of 0.2 MPa to overcome the internal spring and extend the rod.
