This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL25X50SCA, 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 MSAL25X50SCA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL25X50SCA is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø25mm bore and 50mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X50SCA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X50SCA
The AirTAC MSAL25X50SCA is a discontinued single-acting push, spring-return mini cylinder. Air extends the rod to do work, while an internal spring retracts it when air is removed, providing a fail-safe retracted home. It delivers a usable push force of 176.4 N at 0.5 MPa and 274.5 N at 0.7 MPa. The direct replacement is the MSBL25X50SCA, matching the 25mm bore, 50mm stroke, G1/8 port, and CA clevis mount.
This SKU includes the -S magnet for position sensing with CS1-M or DS1-M switches; the MSBL upgrade uses CMSG, DMSG, or EMSG sensors. The MSAL features threaded covers, whereas the MSBL body uses a riveted rolling-packed construction. A fixed rubber bumper absorbs end-of-stroke impact, and the CA back cover provides a pivot pin for arcing loads.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X50SCA Technical Specifications

| Bore size | Ø25 mm |
| Stroke | 50 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X50SCA 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 MSAL25X50SCA Is Used
PCB Router Clamp
Pushes a hold-down arm to secure circuit boards during routing, using 176.4 N at 0.5 MPa. The spring return releases the board safely if air drops.
Bottle Sorting Diverter
Extends a guide flap to push bottles between conveyor lanes. The CA clevis mount allows the arm to swing naturally during the 50mm stroke.
Light Stamping Ejector
Drives a small pin to stamp and eject aluminum tags. The fixed rubber bumper handles the 274.5 N peak impact force at 0.7 MPa.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X50SCA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X50SCA
To replace the MSAL25X50SCA, order the MSBL25X50SCA. Confirm the 25mm bore, 50mm stroke, M10x1.25 rod thread, G1/8 PT port, CA pivot back cover, and magnet. Note the sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG. A minimum of 0.2 MPa air pressure is required to overcome the return spring, and you must apply no external load on the return stroke.
If sizing a new actuator, step down to the 20mm bore (106.8 N push at 0.5 MPa) for lighter ejecting, or step up to the 32mm bore (317.7 N push at 0.5 MPa) for heavier pressing. For a 50mm stroke on these compact bores, watch for side-load and rod-bending forces.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X50SCA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X50SCA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X50SCA FAQ
Yes, the MSAL25X50SCA is discontinued. The direct replacement is the MSBL25X50SCA. It matches the 25mm bore, 50mm stroke, single-acting push function, G1/8 port, and CA clevis mount. You only need to update your sensors, as the MSBL uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M.
The usable push force (already net of the opposing return spring) is 29.2 N at 0.2 MPa, 127.4 N at 0.4 MPa, 176.4 N at 0.5 MPa, 225.5 N at 0.6 MPa, and 274.5 N at 0.7 MPa. The maximum real-world holding is roughly 28 kgf. Operating pressure is 0.2-1.0 MPa, requiring a minimum of 0.2 MPa to overcome the spring.
