This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X20SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X20SCA 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 MSAL20X20SCA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X20SCA 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X20SCA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X20SCA
The AirTAC MSAL20X20SCA is a discontinued single-acting push, spring-return mini cylinder. Air extends the 8 mm rod for the 20 mm work stroke, while an internal spring retracts it to a fail-safe home when air is removed. It delivers a usable push force of 106.8 N at 0.5 MPa. The exact drop-in replacement is the MSBL20X20SCA, matching the bore, stroke, G1/8 port, and CA clevis mount.
This SKU features a -S magnet for position sensing. The legacy MSAL uses older CS1-M or DS1-M reed switches, whereas the MSBL successor upgrades to CMSG, DMSG, or EMSG sensors. The original MSAL body uses threaded covers, while the current MSBL features a riveted rolling-packed body. Both generations use a fixed rubber bumper for end-of-stroke damping, meaning there is no adjustable cushion.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X20SCA Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL20X20SCA |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X20SCA |
| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X20SCA 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 MSAL20X20SCA Is Used
PCB Ejector Pin
Pushes populated circuit boards out of an SMT testing fixture using 106.8 N at 0.5 MPa, relying on the spring return to clear the lane for the next panel.
Light-Part Diverter
Actuates a lightweight plastic flap on a packaging conveyor to sort small bottles, using the fail-safe retracted home to keep the lane open during air loss.
Sensor Calibration Clamp
Holds a small MEMS sensor against a calibration probe with a soft 20 mm stroke, releasing instantly when the 3/2 valve drops air pressure.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X20SCA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X20SCA
To replace this MSAL20X20SCA, install the MSBL20X20SCA. Confirm the 20 mm bore, 20 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. Remember the 0.2 MPa minimum operating pressure is required for air to beat the return spring, and apply no external load on the spring return stroke.
For sizing flexibility, stepping down is not an option as 20 mm is the smallest available bore. If you need more force, step up to the 25 mm bore, which provides 176.4 N of usable push at 0.5 MPa. Because this is a short 20 mm stroke on a small bore, side-load and rod-bending risks are minimal, but you must still align the CA clevis pin precisely to avoid binding.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X20SCA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X20SCA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X20SCA FAQ
Yes, the MSAL20X20SCA is discontinued. The exact drop-in replacement is the MSBL20X20SCA. It matches the 20 mm bore, 20 mm stroke, G1/8 port, and CA clevis. You only need to update your sensors from the old CS1-M/DS1-M to the new CMSG/DMSG/EMSG switches.
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, with a maximum of 17.3 kgf. It requires a minimum operating pressure of 0.2 MPa for the air to overcome the internal return spring. There is no powered pull force, and the fixed rubber bumper cannot be adjusted.
