This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL25X20SU, 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 MSAL25X20SU
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL25X20SU is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø25mm 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 direct replacement is the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X20SU.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X20SU
The AirTAC MSAL25X20SU is a discontinued single-acting push mini cylinder with a 25mm bore and 20mm stroke. Air extends the rod, while an internal spring retracts it to a fail-safe home. The direct replacement is the MSBL25X20SU, which matches the bore, stroke, port, and mounting. This 25mm bore yields a usable push force of 176.4 N at 0.5 MPa and 274.5 N at 0.7 MPa.
This SKU includes the -S magnet for position sensing, originally using CS1-M or DS1-M switches; the MSBL upgrade uses the newer CMSG, DMSG, or EMSG families. The MSAL features threaded covers and a fixed rubber bumper, whereas the MSBL replacement utilizes a riveted rolling-packed body. Operating pressure is 0.2-1.0 MPa, and the U back cover provides a flat rigid rear mounting face.

| Stroke | 20 mm |
| Acting type | Single acting, push (spring return) |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X20SU carries the same single-acting ratings.
Usable Push Force (Ø25mm)
| Pressure | Push force (net of spring) |
|---|---|
| 0.5 MPa | 176.4 N |
| 0.7 MPa | 274.5 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 MSAL25X20SU Is Used
PCB Ejector Pins
Pushes finished circuit boards out of test fixtures using 176.4 N at 0.5 MPa. The spring return safely retracts the pin when air is removed, preventing fixture damage.
Packaging Flap Deflector
Extends to guide carton flaps during case packing. The fail-safe spring-return home ensures the deflector never jams the line if air pressure drops.
Sensor Alignment Stop
Provides a temporary hard stop for moving pallets. The fixed rubber bumper absorbs the 20mm stroke impact quietly without needing adjustment.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X20SU with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X20SU
To replace this MSAL25X20SU, order the MSBL25X20SU. Confirm the 25mm bore, 20mm stroke, G1/8 port, PT thread, U flat-end back cover, and the -S magnet. Remember that the sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG. Minimum working pressure is 0.2 MPa to overcome the return spring, and you must apply no external load on the return stroke. If you need less force, step down to the 20mm bore (106.8 N at 0.5 MPa); if you need more, step up to the 32mm bore (317.7 N at 0.5 MPa).
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X20SU (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X20SU instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X20SU FAQ
Yes, the MSAL25X20SU is discontinued. The direct replacement is the MSBL25X20SU, which matches the 25mm bore, 20mm stroke, single-acting push function, and G1/8 port. You will only need to update your sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG.
The usable push force is 29.2 N at 0.2 MPa, 127.4 N at 0.4 MPa, 176.4 N at 0.5 MPa, and 274.5 N at 0.7 MPa (max kgf is roughly 28 kgf). The operating pressure is 0.2-1.0 MPa, with 0.2 MPa as the minimum to overcome the return spring.
