This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30SCM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30SCM 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 MSAL20X30SCM
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X30SCM is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø20mm bore and 30mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30SCM.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X30SCM
The AirTAC MSAL20X30SCM is a discontinued single-acting push cylinder where air extends the rod and an internal spring retracts it to a fail-safe home. On this 20mm bore, usable push force is 106.8N at 0.5MPa and 169.6N at 0.7MPa. The exact drop-in replacement is the MSBL20X30SCM, matching the 30mm stroke, G1/8 port, and CM round-end cover.
This -S SKU includes a magnet for CS1-M/DS1-M switches; the MSBL upgrade shifts to CMSG/DMSG/EMSG sensors. The MSAL uses threaded covers, whereas the MSBL features a riveted rolling-packed body. End-of-stroke damping relies on a fixed rubber bumper, not an adjustable cushion, and you must apply no external load on the return stroke.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X30SCM Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL20X30SCM |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30SCM |
| Bore size | Ø20 mm |
| Stroke | 30 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30SCM 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 MSAL20X30SCM Is Used
PCB Ejector Pin
Pushes delicate printed circuit boards out of a test fixture using 106.8N at 0.5MPa, relying on the spring return to clear the area when air is removed.
Packaging Flap Deflector
Extends to guide carton flaps on a packing line, with the fail-safe retracted home preventing jams during air pressure drops.
Sensor Test Probe
Applies a precise 169.6N thrust at 0.7MPa to seat electronic components, using the fixed rubber bumper to soften the impact at the test position.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X30SCM with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30SCM
To replace this MSAL20X30SCM, specify the MSBL20X30SCM to retain the 20mm bore, 30mm stroke, PT G1/8 port, M8x1.25 rod thread, CM cover, and magnet (noting the switch change to CMSG/DMSG/EMSG). Ensure your air supply beats the 0.2MPa minimum to overcome the spring. If you need less force, no smaller bore exists in this series. If you need more power, step up to the 25mm bore, which provides 176.4N at 0.5MPa. With this 30mm stroke, side-load risks are low, but maintain rod alignment to prevent guide wear.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30SCM (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30SCM instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X30SCM FAQ
Yes, the MSAL20X30SCM is discontinued. The exact drop-in replacement is the MSBL20X30SCM, which matches the 20mm bore, 30mm stroke, G1/8 port, and CM mounting. You will only need to update your sensors, as the MSBL uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M type.
This single-acting push cylinder delivers a usable force of 106.8N at 0.5MPa and 169.6N at 0.7MPa (max 17.3 kgf). Because an internal spring opposes the air stroke, the minimum working pressure is 0.2MPa to ensure the air can beat the spring and extend the rod.
