This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X40CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X40CA 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 MSAL40X40CA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X40CA 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X40CA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X40CA
The AirTAC MSAL40X40CA is a discontinued single-acting push cylinder with a 40mm bore and 40mm stroke. Air extends the rod to do the work, while an internal spring retracts it. This provides a fail-safe home position on air loss. It delivers a usable push force of 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa. The exact drop-in replacement is the MSBL40X40CA, sharing the same bore, stroke, force class, and G1/4 port.
This CA variant features a pivot clevis back cover that swings on a pin, making it ideal for arcing loads. The original MSAL uses threaded covers and a PT tapered port thread. The modern MSBL upgrade features a riveted rolling-packed body. Because this specific SKU lacks the -S magnet option, it cannot accept a position sensor. It uses a fixed rubber bumper for end-of-stroke damping, as single-acting cylinders do not have adjustable cushions.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X40CA Technical Specifications

| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X40CA 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 MSAL40X40CA Is Used
Stamping Press Ejection
Ejects formed metal blanks from a stamping die. The 539.9 N push force at 0.5 MPa reliably knocks heavy parts free, while the spring return ensures the pin clears the die if air pressure drops.
Woodworking Gate Arm
Actuates a routing machine safety gate. The CA pivot clevis accommodates the arcing swing of the arm, and the fail-safe spring return opens the guard automatically on air loss.
Plastic Injection Mold Breaker
Taps injection-molded plastic parts off the core. The fixed rubber bumper absorbs the 791.1 N peak impact force at 0.7 MPa without damaging the mold face.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X40CA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X40CA
To replace this MSAL40X40CA, order the MSBL40X40CA. Confirm the 40mm bore, 40mm stroke, G1/4 port, PT thread, and CA pivot clevis are correct for your mount. Because this old SKU has no -S magnet, it cannot take a sensor; if you need position detection, step up to an MSBL40X40SCA, which uses the newer CMSG, DMSG, or EMSG switches instead of the old CS1-M/DS1-M family. Remember the 0.2 MPa minimum working pressure needed to overcome the return spring, and apply no external load on the spring return stroke for safety.
For sizing, this 40mm bore provides 539.9 N push at 0.5 MPa. If you need less force, step down to the 32mm bore, which yields 317.7 N at 0.5 MPa. If you need more power, there is no larger standard MAL bore, so you would need to jump to a different cylinder family. At a 40mm stroke on this compact body, side-load and rod-bending risks are minimal, but always ensure the CA clevis pin is greased to handle arcing dynamics.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X40CA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X40CA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X40CA FAQ
Yes, the MSAL40X40CA is discontinued. The exact drop-in replacement is the MSBL40X40CA. It matches the 40mm bore, 40mm stroke, 539.9 N push force at 0.5 MPa, G1/4 port, and CA pivot clevis mounting. The MSBL upgrades the body to a riveted rolling-packed design and uses CMSG/DMSG/EMSG sensors if you add the -S magnet option.
The usable push force (already net of the opposing return spring) is 163.1 N at 0.2 MPa, 414.3 N at 0.4 MPa, 539.9 N at 0.5 MPa, and 791.1 N at 0.7 MPa. The minimum working pressure is 0.2 MPa because the air must overcome the internal return spring to extend the rod.
