This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X20CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X20CA 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 MSAL25X20CA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL25X20CA 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 drop-in replacement is the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X20CA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X20CA
The AirTAC MSAL25X20CA is a discontinued single-acting push cylinder with a 25mm bore and 20mm stroke. Air extends the rod to do its work, while an internal spring retracts it to a fail-safe home when air is removed. It delivers a usable push force of 176.4 N at 0.5 MPa. The exact drop-in replacement is the MSBL25X20CA, matching the bore, stroke, and CA clevis mounting.
This SKU uses a G1/8 port and an M10x1.25 rod end. Because it lacks the -S suffix, it cannot accept a position sensor. As an upgrade fact, the older MSAL uses threaded covers and CS1-M switches, whereas the MSBL replacement features a riveted rolling-packed body and CMSG sensors. End-of-stroke deceleration relies on a fixed rubber bumper, not an adjustable cushion.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X20CA Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL25X20CA |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X20CA |
| Bore size | Ø25 mm |
| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X20CA 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 MSAL25X20CA Is Used
PCB Ejector Pin
Pushes bare circuit boards out of an inspection fixture using 176.4 N at 0.5 MPa, relying on the spring return to clear the bay for the next panel.
Bag Flap Folder
Extends 20mm to tuck packaging material on a form-fill-seal machine, with the fail-safe home preventing jams during an air loss event.
Clevis-Mounted Arc Stop
Uses the CA pivot back cover to swing with an arcing lever arm on a textile loom, arresting a shuttle mechanism cleanly.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X20CA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X20CA
To replace this MSAL25X20CA with the MSBL25X20CA, confirm the 25mm bore, 20mm stroke, G1/8 PT thread, and CA pivot back cover. Remember the 0.2 MPa minimum operating pressure required to overcome the return spring, and apply no external load on the return stroke. If you need to step down, the 20mm bore offers 106.8 N at 0.5 MPa; if you need to step up, the 32mm bore provides 317.7 N at 0.5 MPa. Even at this short 20mm stroke, ensure your mounting guards against side-load rod-bending.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X20CA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X20CA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X20CA FAQ
Yes, the MSAL25X20CA is discontinued. The exact drop-in replacement is the MSBL25X20CA, which matches the 25mm bore, 20mm stroke, CA clevis mount, and G1/8 port. The MSBL upgrades the body to a riveted rolling-packed design but retains the same force class.
This single-acting push cylinder delivers 176.4 N of usable force at 0.5 MPa and 274.5 N at 0.7 MPa. It requires a minimum operating pressure of 0.2 MPa to overcome the internal return spring. The maximum force is 274.5 N (about 28 kgf) at 0.7 MPa.
