This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25CA 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 MSAL40X25CA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X25CA 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25CA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X25CA
The AirTAC MSAL40X25CA is a discontinued single-acting push mini cylinder with spring return. Air extends the rod for the work stroke, while an internal spring retracts it, providing a fail-safe retracted home on air loss. For this 40mm bore, usable push force is 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa, with a minimum operating pressure of 0.2 MPa. The exact drop-in replacement is the MSBL40X25CA, matching the bore, stroke, port, and force.
This SKU features a CA pivot clevis back cover that swings on a pin to absorb arcing loads. It has no magnet (-S), meaning it cannot accept a position sensor. The legacy MSAL uses threaded covers and older CS1-M/DS1-M switches, while the MSBL replacement upgrades to a riveted rolling-packed body and CMSG/DMSG/EMSG sensors. A fixed rubber bumper absorbs end-of-stroke impact, and you must apply no external load on the spring return stroke.

| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25CA 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 MSAL40X25CA Is Used
Stamping Press Ejection
Uses the 539.9 N push force at 0.5 MPa to eject small stamped metal parts from a die, with the spring safely returning the rod when air is removed.
Packaging Flap Folding
Extends to fold cardboard carton flaps on a packaging line; the CA pivot clevis absorbs arcing motion as the rod travels through the arc.
Pneumatic Gate Diverter
Shifts a diverter gate on a conveyor system; the spring-return fail-safe home ensures the gate moves back to the retracted rest position during an air loss event.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X25CA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25CA
To replace this MSAL40X25CA, install the MSBL40X25CA. Confirm the 40mm bore, 25mm stroke, G1/4 port, PT thread, and CA pivot clevis. Because this SKU lacks the -S magnet, it cannot take a sensor; if you need position detection, step up to an MSBL40X25SCA and use CMSG/DMSG/EMSG switches. Maintain the 0.2 MPa minimum air pressure to overcome the return spring, and never apply external load on the return stroke.
For sizing both ways: if you need less force, the next size down is bore 32, yielding 317.7 N push at 0.5 MPa. If you need more force, 40mm is the largest standard MSAL bore, so you would step up to a larger ISO 15552 series cylinder. With a 25mm stroke on this 40mm bore, side-load and rod-bending risks are minimal, but ensure the CA clevis pin is lubricated for smooth articulation.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25CA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X25CA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X25CA FAQ
Yes, the MSAL40X25CA is discontinued. The exact drop-in replacement is the MSBL40X25CA, which matches the 40mm bore, 25mm stroke, G1/4 port, CA clevis, and force class. The MSBL upgrades the body to a riveted rolling-packed design.
The usable push force (net of the return spring) is 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa. The minimum operating pressure is 0.2 MPa because the air must overcome the internal return spring to extend the rod.
