This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X20CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X20CM 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 MSAL20X20CM
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X20CM is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø20mm bore and 20mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X20CM.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X20CM
The AirTAC MSAL20X20CM is a discontinued single-acting push mini cylinder with a 20mm bore and 20mm stroke. Air extends the rod to provide a usable push force of 106.8 N at 0.5 MPa, while an internal spring retracts it for a fail-safe home on air loss. The exact drop-in replacement is the MSBL20X20CM, matching the bore, stroke, G1/8 port, and CM round-end cover.
This CM round-end SKU lacks the -S suffix, so it cannot take a position sensor. As an upgrade fact, the MSAL uses threaded covers and older switches, while the MSBL replacement features a riveted rolling-packed body. The fixed rubber bumper absorbs end-of-stroke impact, and the minimum operating pressure is 0.2 MPa to overcome the return spring.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X20CM Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL20X20CM |

| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X20CM |
| Bore size | Ø20 mm |
| Stroke | 20 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X20CM 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 MSAL20X20CM Is Used
PCB Ejector Pins
Pushes delicate printed circuit boards out of an SMT pick-and-place fixture using 106.8 N at 0.5 MPa, with the spring safely retracting the pin when air is removed.
Sensor Gate Diverter
Acts as a fail-safe gate in a small electronics testing line, blocking parts under power and snapping back to clear the path on air loss.
Light-Part Stamper
Applies a short 20mm stamping motion to thin foil labels, relying on the fixed rubber bumper to halt the stroke cleanly without adjustable cushioning.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X20CM with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X20CM
To replace this MSAL20X20CM, specify the MSBL20X20CM to match the 20mm bore, 20mm stroke, PT G1/8 port, CM round-end cover, and non-magnet configuration. Remember the 0.2 MPa minimum air pressure requirement, and apply no external load on the spring return stroke. If you need less force, there is no smaller standard bore in this family. If you need more force, step up to the 25mm bore, which provides 176.4 N at 0.5 MPa. For this 20mm stroke, side-load and rod-bending risks are minimal.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X20CM (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X20CM instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X20CM FAQ
Yes, the MSAL20X20CM is discontinued. The exact drop-in replacement is the MSBL20X20CM, which matches the 20mm bore, 20mm stroke, G1/8 port, and CM round-end cover. The MSBL upgrades the body to a riveted rolling-packed design.
It provides a usable push force of 106.8 N at 0.5 MPa and 169.6 N at 0.7 MPa. The operating pressure range is 0.2-1.0 MPa, with a 0.2 MPa minimum required to overcome the internal return spring. This SKU has no magnet and cannot support a sensor.
