This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X15CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X15CA 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 MSAL40X15CA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X15CA is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø40mm bore and 15mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X15CA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X15CA
The AirTAC MSAL40X15CA is a discontinued 40mm bore, single-acting push cylinder with a 15mm stroke and a CA pivot clevis back cover. Air extends the rod to do the work, while an internal spring retracts it when air is removed, providing a fail-safe retracted home on air loss. As a 40mm bore unit, it uses a G1/4 port and a Ø16mm hard-chrome carbon steel rod with an M12x1.25 end thread. 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 MSBL40X15CA, which retains the same bore, stroke, CA clevis, force class, and G1/4 port. Two key upgrade facts: the MSAL uses older threaded covers, whereas the MSBL features a riveted rolling-packed body for better sealing integrity. Additionally, because this specific MSAL40X15CA SKU lacks the -S magnet code, it cannot accept any position sensor; the MSBL upgrade path allows for CMSG/DMSG/EMSG switches if needed on future -S SKUs. End-of-stroke energy is absorbed by a fixed rubber bumper, not an adjustable cushion.

| Stroke | 15 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 |

| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X15CA 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 MSAL40X15CA Is Used
Stamping Press Ejector
Ejects small stamped metal parts from a die using 539.9 N of push force at 0.5 MPa, relying on the spring return to clear the die safely before the next cycle.
Welding Fixture Clamp
Holds a steel bracket in a robotic weld cell; the CA pivot clevis accommodates slight arc misalignment, while the fail-safe retracted home prevents clamp interference if air pressure drops.
Packaging Flap Folder
Pushes cardboard carton flaps closed on a packaging line with 791.1 N at 0.7 MPa, where the short 15mm stroke and fixed rubber bumper provide rapid, cushioned end-stop positioning.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X15CA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X15CA
To replace this MSAL40X15CA, order the MSBL40X15CA. Confirm the 40mm bore, 15mm stroke, G1/4 PT thread, and CA pivot clevis back cover. Because this SKU has no -S magnet, it cannot take a sensor; if you need position feedback on the new MSBL, you must add the -S option and switch to CMSG/DMSG/EMSG sensors. Remember the 0.2 MPa minimum operating pressure required to overcome the return spring, and apply NO external load on the spring return stroke for safety.
For sizing flexibility, you can step down to the 32mm bore (G1/8 port, 317.7 N push at 0.5 MPa) if your clamping force is lower, or step up to a larger double-acting MAL if you need powered retraction. The short 15mm stroke on this 40mm bore minimizes rod-bending side-load risks, but ensure the CA clevis pin is aligned to prevent binding during the arc of motion.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X15CA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X15CA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X15CA FAQ
Yes, the MSAL40X15CA is discontinued. The exact drop-in replacement is the MSBL40X15CA, which matches the 40mm bore, 15mm stroke, CA pivot clevis, G1/4 port, and force class. The MSBL upgrades the construction to a riveted rolling-packed body instead of threaded covers.
This single-acting push cylinder delivers a usable force of 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa (equivalent to roughly 80.6 kgf max). It operates on 0.2-1.0 MPa air pressure, with a 0.2 MPa minimum required to overcome the internal return spring. It has a fixed rubber bumper and no adjustable cushion.
