This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25CM 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 MSAL40X25CM
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X25CM 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25CM.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X25CM
The AirTAC MSAL40X25CM is a discontinued single-acting push cylinder with a 40 mm bore and 25 mm 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 MSBL40X25CM, which matches the bore, stroke, G1/4 port, and CM round-end back cover.
This CM-cover SKU has no -S magnet, so it cannot accept a position sensor. As an upgrade path, the MSAL uses older threaded covers and CS1-M/DS1-M switches, whereas the MSBL features a riveted rolling-packed body and CMSG/DMSG/EMSG sensors. Impact absorption relies on a fixed rubber bumper, meaning there is no adjustable cushion. Never apply an external load on the unpowered spring return stroke.

| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25CM 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 MSAL40X25CM Is Used
Stamping Press Ejection
Ejects formed sheet metal parts from a stamping die using 539.9 N of push force at 0.5 MPa, relying on the spring return to clear the die cavity during air loss.
PCB Router Clamping
Secures printed circuit board panels inside a CNC routing fixture; the fail-safe retracted home prevents the clamp from crushing boards if shop air drops.
Packaging Diverter Gate
Pushes a mechanical diverter gate to route cartons on a packaging conveyor, where the fixed rubber bumper absorbs the repetitive end-of-stroke impact.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X25CM with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25CM
To replace this MSAL40X25CM, specify the MSBL40X25CM and confirm the 40 mm bore, 25 mm stroke, PT G1/4 port, M12x1.25 rod-end thread, and CM round-end cover. Because this SKU lacks the -S magnet, you cannot mount a sensor without changing the cylinder; the MSBL equivalent would use CMSG/DMSG/EMSG switches. Remember the 0.2 MPa minimum working pressure required to overcome the return spring, and never apply external load on the return stroke.
For sizing flexibility, stepping down to the 32 mm bore drops the 0.5 MPa push force to 317.7 N. If you need more power, note that 40 mm is the largest standard MSAL size, so exceeding 791.1 N at 0.7 MPa requires migrating to a double-acting MAL series. With a 25 mm stroke on this 40 mm bore, side-load and rod-bending risks are minimal, but always verify rigid rod-end alignment.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25CM (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25CM instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X25CM FAQ
Yes, the MSAL40X25CM is discontinued. The exact drop-in replacement is the MSBL40X25CM, which matches the 40 mm bore, 25 mm stroke, G1/4 port, and CM mounting. You will need to upgrade to CMSG/DMSG/EMSG sensors if you previously used CS1-M/DS1-M switches, though this specific no-magnet SKU cannot take a sensor.
This single-acting push cylinder delivers 539.9 N of usable force at 0.5 MPa and 791.1 N at 0.7 MPa (roughly 80.6 kgf). The operating pressure range is 0.2-1.0 MPa, with a 0.2 MPa minimum required to overcome the internal return spring. There is no powered retraction force; the spring only provides a small fail-safe return.
