This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL25X40CA, 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 MSAL25X40CA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL25X40CA is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø25mm bore and 40mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X40CA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X40CA
The AirTAC MSAL25X40CA is a discontinued single-acting push, spring-return mini cylinder. Air extends the 25 mm bore rod for a 40 mm stroke, while an internal spring retracts it to a fail-safe home on air loss. It delivers 176.4 N usable push force at 0.5 MPa and requires a minimum 0.2 MPa to overcome the spring. The direct replacement is the MSBL25X40CA, sharing the same bore, stroke, and CA clevis mount.
This non-magnet SKU cannot accept a position sensor. Upgrading to the MSBL25X40CA moves you from the older threaded covers to a riveted rolling-packed body. If you need sensors, the MSBL -S variant uses the newer CMSG/DMSG/EMSG switches instead of the legacy CS1-M/DS1-M family. A fixed rubber bumper absorbs end-of-stroke impact, as no adjustable cushion exists on this series.

| Stroke | 40 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X40CA 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 MSAL25X40CA Is Used
PCB Depaneling Gate
Pushes a routing gate open with 176.4 N at 0.5 MPa to separate populated PCB panels, relying on the spring to safely retract the pin when air drops.
Textile Loom Tensioner
Uses the CA pivot back cover to swing a yarn tensioning arm into place during weaving, absorbing minor arc deviations without binding.
Bottle Cap Sorter
Ejects inverted plastic caps from a vibratory bowl feeder with 274.5 N at 0.7 MPa, letting the fixed rubber bumper absorb the repetitive impact.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X40CA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X40CA
To replace this MSAL25X40CA, specify the MSBL25X40CA and confirm the 25 mm bore, 40 mm stroke, G1/8 PT port, M10x1.25 rod-end thread, and CA pivot back cover. Remember the 0.2 MPa minimum operating pressure and apply no external load on the spring return stroke. Stepping down, the 20 mm bore gives 106.8 N push at 0.5 MPa; stepping up, the 32 mm bore yields 317.7 N at 0.5 MPa. Keep the 40 mm stroke on this small bore, but verify side-load alignment to prevent rod-bending.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X40CA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X40CA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X40CA FAQ
Yes, the MSAL25X40CA is discontinued. The direct replacement is the MSBL25X40CA, matching the 25 mm bore, 40 mm stroke, CA pivot back cover, and G1/8 port. The MSBL upgrades the body to a riveted rolling-packed design.
The 25 mm bore single-acting push force is 176.4 N at 0.5 MPa and 274.5 N at 0.7 MPa. The maximum force is 274.5 N (about 28 kgf). It requires a minimum 0.2 MPa air pressure to beat the return spring and operate.
