This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X40U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X40U 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 MSAL40X40U
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X40U is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø40mm bore and 40mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X40U.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X40U
The AirTAC MSAL40X40U is a discontinued single-acting push cylinder with a 40 mm bore and 40 mm stroke. Air extends the rod for the work stroke, while an internal spring retracts it to a fail-safe home when air is removed. It delivers 539.9 N of usable push force at 0.5 MPa and 791.1 N at 0.7 MPa. The exact drop-in replacement is the MSBL40X40U, which matches the bore, stroke, G1/4 port, and U flat-end back cover.
This U-back-cover variant has a rigid flat rear for direct mounting. Because this SKU lacks the -S magnet, it cannot take a position sensor. The original MSAL uses threaded covers and the older CS1-M or DS1-M switches, whereas the MSBL upgrade features a riveted rolling-packed body and uses CMSG, DMSG, or EMSG sensors. End-of-stroke damping relies on a fixed rubber bumper, not an adjustable cushion.

| Stroke | 40 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X40U 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 MSAL40X40U Is Used
Punch Press Ejection
Ejects stamped metal blanks from a die. The 539.9 N push force at 0.5 MPa clears heavy parts, and the spring return ensures the ejector pin retracts clear before the next press cycle.
Packaging Flap Folding
Folds heavy cardboard carton flaps on a sealing line. Air extends the rod to push the flap down, and the fail-safe spring return releases the load if the pneumatic air supply drops.
Injection Mold Parting
Pushes a secondary ejector pin to break small plastic parts from an injection mold. The fixed rubber bumper absorbs the end-of-stroke impact, protecting the mold face.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X40U with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X40U
To replace the MSAL40X40U, use the drop-in MSBL40X40U. Confirm the 40 mm bore, 40 mm stroke, G1/4 port, PT thread, U flat-end back cover, and the lack of a magnet (this no-sensor SKU transitions to a no-sensor MSBL). Remember the 0.2 MPa minimum operating pressure required for air to overcome the return spring. Never apply an external load on the spring return stroke, as this is a fail-safe home, not a lock.
If you need to step down from this 40 mm bore, the 32 mm bore provides 317.7 N of push force at 0.5 MPa. The 40 mm is the largest standard bore in this mini series, so there is no larger neighbour to step up to. For a 40 mm stroke on this bore, the rod is robust against bending, but always avoid side loads to preserve the front-cover guide.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X40U (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X40U instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X40U FAQ
Yes, the MSAL40X40U is discontinued. The exact drop-in replacement is the MSBL40X40U, which matches the 40 mm bore, 40 mm stroke, G1/4 port, and U flat-end back cover. The MSBL upgrade uses a riveted rolling-packed body instead of threaded covers.
The usable push force is 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa (max 80.7 kgf). The minimum operating pressure is 0.2 MPa because the incoming air must overcome the internal return spring to extend the rod.
