This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25U 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 MSAL40X25U
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X25U is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø40mm bore and 25mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25U.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X25U
The AirTAC MSAL40X25U is a discontinued single-acting push cylinder with a 40mm bore and 25mm stroke. Air extends the rod to deliver 539.9 N of usable push force at 0.5 MPa, while an internal spring retracts it to a fail-safe home when air is removed. The exact drop-in replacement is the MSBL40X25U, which matches the bore, stroke, G1/4 port, and U flat-end back cover.
This U-cover SKU lacks the -S magnet option and cannot accept a position sensor. As a legacy unit, it features threaded covers and uses fixed rubber bumpers instead of adjustable cushions. The modern MSBL replacement upgrades the body to a riveted rolling-packed design; if you ever need sensors on the new unit, you must migrate from the older CS1-M / DS1-M switches to the CMSG / DMSG / EMSG family.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X25U Technical Specifications

| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25U |
| Bore size | Ø40 mm |
| Stroke | 25 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25U 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 MSAL40X25U Is Used
Stamping Press Ejection
Ejects formed sheet metal brackets from a stamping die using 539.9 N of push force at 0.5 MPa, relying on the spring return to clear the bed before the next cycle.
Woodworking Door Clamp
Holds cabinet doors steady during hinge routing on a CNC router, using the fail-safe spring return to release the part safely if shop air pressure drops.
Packaging Line Diverter
Pushes corrugated cartons onto a secondary packaging belt, where the short 25mm stroke and fixed rubber bumper absorb the impact without needing adjustable cushions.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X25U with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25U
To replace this MSAL40X25U, migrate to the MSBL40X25U and verify your 40mm bore, 25mm stroke, G1/4 port, PT thread, and U flat-end back cover. Because this is a no-magnet SKU, it cannot hold a sensor; if your upgrade requires position detection, select an MSBL40X25US and use CMSG / DMSG / EMSG switches. Remember the 0.2 MPa minimum operating pressure required to overcome the return spring, and apply no external load on the spring return stroke.
If sizing your force requirements, stepping down to a 32mm bore drops the 0.5 MPa push force to 317.7 N, while this 40mm unit provides 539.9 N. There is no larger standard bore in this mini series, so for higher demands you must jump to an ISO 15552 profile cylinder. The 25mm stroke is compact, but always guard against side-load and rod-bending forces on the 16mm rod.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25U (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25U instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X25U FAQ
Yes, the MSAL40X25U is discontinued. The exact drop-in replacement is the MSBL40X25U, which matches the 40mm bore, 25mm stroke, G1/4 port, and U flat-end back cover. The MSBL upgrades the threaded covers to a riveted rolling-packed body.
The usable push force is 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa, with a maximum of 80.7 kgf. The operating pressure range is 0.2-1.0 MPa; a 0.2 MPa minimum is required because the air must overcome the internal return spring.
