This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X40SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X40SCA 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 MSAL20X40SCA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X40SCA is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø20mm bore and 40mm stroke, G1/8 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X40SCA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X40SCA
The AirTAC MSAL20X40SCA is a discontinued single-acting push cylinder with a 40 mm stroke. Air extends the Ø8 mm rod to deliver 106.8 N of usable push force at 0.5 MPa, while an internal spring retracts it to a fail-safe home when air is removed. The exact drop-in replacement is the MSBL20X40SCA, matching the bore, stroke, G1/8 port, and CA clevis mount.
This SKU features a -S magnet for legacy CS1-M / DS1-M reed switches; the MSBL successor upgrades to CMSG / DMSG / EMSG sensors. The MSAL uses threaded covers, whereas the MSBL features a riveted rolling-packed body. Both share a fixed rubber bumper, requiring no external load on the spring return stroke, and operate safely from 0.2 to 1.0 MPa.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X40SCA Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL20X40SCA |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X40SCA |
| Bore size | Ø20 mm |
| Stroke | 40 mm |
| Acting type | Single acting, push (spring return) |
| Port size | G1/8 |
| Rod thread | M8×1.25 |
| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X40SCA carries the same single-acting ratings.
Usable Push Force (Ø20mm)
| Pressure | Push force (net of spring) |
|---|---|
| 0.5 MPa | 106.8 N |
| 0.7 MPa | 169.6 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 MSAL20X40SCA Is Used
PCB Ejector Pin
Pushes bare circuit boards out of an inspection fixture with 106.8 N at 0.5 MPa, relying on the spring return to safely retract the pin when air is cut.
Small Parts Diverter
Arcs lightweight plastic caps on a conveyor using the CA pivot clevis, swinging the rod into place to gate flow before springing back to home.
Cassette Latching
Extends to lock a sliding battery tray in a test rack, with the fail-safe retracted home ensuring the latch releases automatically on air loss.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X40SCA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X40SCA
To replace this MSAL20X40SCA, install the MSBL20X40SCA. Confirm the 20 mm bore, 40 mm stroke, PT G1/8 port, M8x1.25 rod thread, CA pivot clevis, and the sensor family change from CS1-M/DS1-M to CMSG/DMSG/EMSG. Maintain a minimum 0.2 MPa air pressure to overcome the return spring, and apply no external load on the return stroke.
If sizing a new application, step down to the smaller bore if less force is needed, or step up to the 25 mm bore which provides 176.4 N of push at 0.5 MPa. At 40 mm of stroke on this compact frame, verify rod alignment to prevent side-loading and premature guide wear.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X40SCA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X40SCA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X40SCA FAQ
Yes, the MSAL20X40SCA is discontinued. The exact drop-in replacement is the MSBL20X40SCA, matching the 20 mm bore, 40 mm stroke, G1/8 port, and CA clevis. You will only need to update your sensors, as the legacy CS1-M / DS1-M switches are replaced by CMSG / DMSG / EMSG models on the MSBL.
This single-acting push cylinder delivers a usable force of 106.8 N at 0.5 MPa and 169.6 N at 0.7 MPa. Because an internal spring opposes the air stroke, the minimum working pressure is 0.2 MPa to ensure the air can overcome the spring to extend the rod.
