This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X50SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X50SU 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 MSAL40X50SU
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X50SU is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø40mm bore and 50mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X50SU.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X50SU
The AirTAC MSAL40X50SU is a discontinued 40mm bore, 50mm stroke single-acting push cylinder. Air extends the rod to do work, while an internal spring retracts it to a fail-safe home when pressure drops. It delivers 539.9 N of usable push force at 0.5 MPa and 791.1 N at 0.7 MPa. The exact drop-in replacement is the MSBL40X50SU, matching the bore, stroke, G1/4 port, and U back cover.
This SKU features a -S magnet for position sensing via older CS1-M or DS1-M switches; the MSBL successor uses CMSG, DMSG, or EMSG sensors. The MSAL relies on threaded covers, whereas the MSBL features a riveted rolling-packed body. End-of-stroke energy is absorbed by a fixed rubber bumper, not an adjustable cushion.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X50SU Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL40X50SU |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X50SU |
| Bore size | Ø40 mm |
| Stroke | 50 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X50SU 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 MSAL40X50SU Is Used
Stamping Press Ejector
Ejects formed sheet metal blanks from a die using 539.9 N of push at 0.5 MPa, relying on the spring return to clear the bed before the next cycle.
Injection Mold Gate
Actuates a diverter gate on an injection molding hopper, where the single-acting design ensures the chute closes to a safe home position on air loss.
Bottling Line Diverter
Pushes glass bottles onto a packaging conveyor lane using 791.1 N at 0.7 MPa, with the fixed rubber bumper absorbing the impact at full extension.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X50SU with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X50SU
To replace the MSAL40X50SU, install the MSBL40X50SU. Confirm the 40mm bore, 50mm stroke, G1/4 port, PT thread, U flat-end back cover, and -S magnet. Remember that the MSBL requires CMSG, DMSG, or EMSG switches instead of the older CS1-M/DS1-M. Operating pressure must be at least 0.2 MPa to overcome the return spring, and you must apply no external load on the return stroke.
If sizing down, the 32mm bore neighbor yields 317.7 N at 0.5 MPa. If stepping up, 40mm is the largest MSAL size, so for higher force you must migrate to a different cylinder family. For this 50mm stroke on a small body, ensure the front-cover guide handles any side-load to prevent rod-bending.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X50SU (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X50SU instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X50SU FAQ
Yes, the MSAL40X50SU is discontinued. The exact drop-in replacement is the MSBL40X50SU, which matches the 40mm bore, 50mm stroke, G1/4 port, and U back cover. Note that if you use the -S magnet for sensing, you must upgrade from the older CS1-M/DS1-M switches to the CMSG/DMSG/EMSG family.
The usable push force 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 compressed air must first overcome the internal return spring to extend the rod.
