This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL20X25U, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 MSAL20X25U
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X25U 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 direct replacement is the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25U.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X25U
The AirTAC MSAL20X25U is a discontinued single-acting push mini cylinder with a 20mm bore and 25mm stroke. Air extends the rod while an internal spring retracts it, providing a fail-safe retracted home on air loss. It delivers 106.8 N of usable push force at 0.5 MPa (169.6 N at 0.7 MPa) and requires a minimum 0.2 MPa to overcome the return spring.
The direct replacement is the MSBL20X25U, matching the bore, stroke, U flat-end back cover, and G1/8 PT port. This SKU lacks the -S magnet and cannot take a position sensor. Upgrade facts: the MSAL uses threaded covers and older CS1-M/DS1-M switches, while the MSBL features a riveted rolling-packed body and CMSG/DMSG/EMSG sensors.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X25U Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL20X25U |

| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25U |
| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25U 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 MSAL20X25U Is Used
PCB Ejector Pins
Pushes thin printed circuit boards out of a test fixture with 106.8 N at 0.5 MPa, using the spring return to safely retract the pin when air is cut.
Chip Tray Stops
Acts as a stop gate for semiconductor chip trays, extending to block flow and spring-retracting to a fail-safe open home during an air loss event.
Light Plastic Pressing
Provides a short 25mm stroke to press light plastic caps into housings, relying on the fixed rubber bumper to absorb end-of-stroke impact.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X25U with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25U
Replace this MSAL20X25U with the MSBL20X25U, confirming the 20mm bore, 25mm stroke, G1/8 PT port, U flat-end back cover, and non-magnet setup. Operating pressure is 0.2-1.0 MPa. Apply NO external load on the spring return stroke. If you need less force, step down to the 12mm bore class; if you need more, step up to the 25mm bore, which provides 176.4 N at 0.5 MPa. At this 25mm stroke, side-load risk is low, but maintain straight alignment to protect the 8mm rod.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25U (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25U instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X25U FAQ
Yes, the MSAL20X25U is discontinued. The direct replacement is the MSBL20X25U, which matches the 20mm bore, 25mm stroke, U flat-end back cover, and G1/8 port. The MSBL upgrades the body to a riveted rolling-packed design.
The usable push force is 106.8 N at 0.5 MPa and 169.6 N at 0.7 MPa. The minimum operating pressure is 0.2 MPa because the air must overcome the internal return spring. This SKU has no -S magnet and cannot accept a position sensor.
