This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X150SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X150SU 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 MSAL40X150SU
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X150SU is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø40mm bore and 150mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X150SU.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X150SU
The AirTAC MSAL40X150SU is a discontinued single-acting push, spring-return mini cylinder. Air extends the rod for the work stroke, while an internal spring retracts it to a fail-safe home when air is removed. This 40 mm bore 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 MSBL40X150SU, matching the bore, stroke, G1/4 port, and mounting.
This SKU features a -S magnet for position sensing, utilizing the older CS1-M or DS1-M reed switches; the MSBL replacement upgrades to CMSG, DMSG, or EMSG sensors. The MSAL uses threaded covers, whereas the MSBL features a riveted rolling-packed body. End-of-stroke energy is absorbed by a fixed rubber bumper, as no adjustable cushion is present in this single-acting design.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X150SU Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL40X150SU |

| Stroke | 150 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X150SU 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 MSAL40X150SU Is Used
Stamping Press Ejection
Ejects stamped metal sheets from a press bed with 539.9 N at 0.5 MPa, relying on the spring return to safely retract the rod when air is cut.
Board Feeder Gate
Acts as a diverter gate for PCB routing, pushing with 791.1 N at 0.7 MPa to redirect panels while the fail-safe home prevents jams during air loss.
Mold Clamp Release
Holds and releases low-pressure silicone molds in an oven, using the fixed rubber bumper to absorb the 150 mm stroke impact without adjustable cushions.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X150SU with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X150SU
Replace this MSAL40X150SU directly with the MSBL40X150SU. Confirm the 40 mm bore, 150 mm stroke, G1/4 port, PT thread, U flat-end back cover, and -S magnet. Remember that the sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG. 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 for safety. Stepping down, the 32 mm bore provides 317.7 N at 0.5 MPa; stepping up is not possible as 40 mm is the largest MSAL size. Because this 150 mm stroke is the maximum standard length on a small bore, verify your guiding to prevent rod-bending side loads.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X150SU (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X150SU instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X150SU FAQ
Yes, the MSAL40X150SU is discontinued. The exact drop-in replacement is the MSBL40X150SU, which matches the 40 mm bore, 150 mm stroke, U back cover, G1/4 port, and mounting. The MSBL upgrades the body to a riveted rolling-packed design and changes the sensor compatibility from CS1-M/DS1-M to CMSG/DMSG/EMSG.
The usable push force is 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa, yielding a maximum of roughly 80.6 kgf. The minimum operating pressure is 0.2 MPa, which is required for the air to overcome the internal return spring and extend the rod.
