This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X100SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X100SU 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 MSAL40X100SU
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X100SU is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø40mm bore and 100mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X100SU.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X100SU
The AirTAC MSAL40X100SU is a discontinued single-acting push, spring-return mini cylinder. Air extends the rod to perform work, while an internal spring retracts it to a fail-safe home when air is removed. 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 MSBL40X100SU, matching the 40mm bore, 100mm stroke, G1/4 port, and U back cover.
This SKU features a -S magnet for position sensing using the older CS1-M or DS1-M switches; the MSBL successor upgrades to CMSG, DMSG, or EMSG sensors. The MSAL uses threaded covers, whereas the MSBL features a riveted rolling-packed body. End-of-stroke deceleration relies on a fixed rubber bumper, as no adjustable cushion exists on this series.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X100SU Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL40X100SU |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X100SU |
| Bore size | Ø40 mm |
| Stroke | 100 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X100SU 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 MSAL40X100SU Is Used
Sheet Metal Stamping Ejector
Uses the 539.9 N push force at 0.5 MPa to knock stamped brackets out of a press die, relying on the spring return to clear the tooling before the next cycle.
PCB Router Gate
Extends 100mm to block off a conveyor lane during board routing, with the fail-safe retracted home ensuring lanes stay open during an air loss event.
Bottle Divert Arm
Pushes a mechanical diverter to route glass containers on a packaging line, using the fixed rubber bumper to absorb the 50-800 mm/s end-of-stroke impact.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X100SU with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X100SU
To replace this MSAL40X100SU, specify the MSBL40X100SU to retain the 40mm bore, 100mm stroke, PT G1/4 port, M12x1.25 rod thread, U flat-end back cover, and magnet. Remember the sensor family change from CS1-M/DS1-M to CMSG/DMSG/EMSG. A minimum 0.2 MPa operating pressure is required to overcome the return spring, and you must apply no external load on the return stroke.
If sizing force, step down to a 32mm bore providing 317.7 N at 0.5 MPa, or step up if you need more power. At 100mm of travel on this 40mm body, verify side-load alignment to prevent rod-bending and guide wear.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X100SU (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X100SU instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X100SU FAQ
Yes, the MSAL40X100SU is discontinued. The exact drop-in replacement is the MSBL40X100SU, which matches the 40mm bore, 100mm stroke, G1/4 port, U back cover, and magnet. You will need to upgrade your position sensors from the older CS1-M/DS1-M 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, yielding a maximum of about 80.7 kgf. Operating pressure must be 0.2-1.0 MPa, with a 0.2 MPa minimum required to overcome the return spring and extend the rod.
