This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25SCA 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 MSAL20X25SCA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X25SCA is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø20mm bore and 25mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25SCA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X25SCA
The AirTAC MSAL20X25SCA is a discontinued single-acting push cylinder with a 20mm bore and 25mm stroke. Air extends the 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 MSBL20X25SCA, matching the bore, stroke, G1/8 port, and CA clevis mount.
This -S variant includes a magnet for legacy CS1-M or DS1-M reed switches; the MSBL replacement upgrades this to CMSG, DMSG, or EMSG sensors. The original MSAL features threaded covers, whereas the MSBL uses a riveted rolling-packed body. Both share a fixed rubber bumper, as single-acting models lack adjustable cushions. The CA back cover provides a pivot pin interface, ideal for arcing rod paths.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X25SCA Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL20X25SCA |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25SCA |
| Bore size | Ø20 mm |
| Stroke | 25 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25SCA 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 MSAL20X25SCA Is Used
PCB Ejector Pin
Pushes bare circuit boards out of an SMT testing fixture using 106.8 N at 0.5 MPa, relying on the spring return to retract the pin safely during panel transfers.
Pivot Arm Diverter
Swings a lightweight aluminum sorting gate on a packaging conveyor; the CA clevis accommodates the arcing motion while air extends the rod.
Connector Press
Applies a brief 169.6 N push at 0.7 MPa to seat ribbon cable headers, with the fail-safe home ensuring the tool retracts if compressed air drops.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X25SCA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25SCA
To replace this MSAL20X25SCA, order the MSBL20X25SCA and confirm the 20mm bore, 25mm stroke, PT G1/8 port, M8x1.25 rod thread, CA clevis, and -S magnet (noting the sensor switch family change). Minimum operating pressure is 0.2 MPa to overcome the return spring, and you must apply no external load on the return stroke. If sizing alternatives, stepping up to the 25mm bore yields 176.4 N at 0.5 MPa, while no smaller standard bore exists in this family. At this 25mm stroke, rod bending is minimal, but always verify side-load limits.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25SCA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25SCA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X25SCA FAQ
Yes, the MSAL20X25SCA is discontinued. The exact drop-in replacement is the MSBL20X25SCA, matching the 20mm bore, 25mm stroke, CA clevis, and G1/8 port. You will only need to upgrade your CS1-M/DS1-M switches to CMSG/DMSG/EMSG sensors for the new magnet.
The usable push force is 106.8 N at 0.5 MPa and 169.6 N at 0.7 MPa (about 17.3 kgf). Because it is single-acting push with a return spring, the minimum working pressure is 0.2 MPa to ensure air can overcome the spring.
