This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X100U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X100U 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 MSAL25X100U
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL25X100U is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø25mm bore and 100mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X100U.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X100U
The AirTAC MSAL25X100U is a discontinued single-acting push cylinder with a 25mm bore and 100mm 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 MSBL25X100U, matching the bore, stroke, G1/8 port, and U back cover.
This U-cover SKU lacks the -S magnet option, so it cannot accept a position sensor. When upgrading to the MSBL, note the construction change: the older MSAL uses threaded covers, while the MSBL features a riveted rolling-packed body. End-of-stroke deceleration relies on a fixed rubber bumper, as single-acting models do not use adjustable cushions. Apply no external load on the spring return stroke to avoid damaging the internal mechanism.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X100U Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL25X100U |

| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X100U |
| Bore size | Ø25 mm |
| Stroke | 100 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X100U 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 MSAL25X100U Is Used
PCB Ejector Pin
Pushes bare circuit boards out of an assembly fixture with 176.4 N at 0.5 MPa; the spring return retracts the pin clear of the board for the next cycle.
Textile Loom Diverter
Extends 100mm to guide a thread strand into a secondary winding path; air removal instantly springs the gate back to a safe home position during a jam.
Lightweight Carton Flap Press
Holds a glued cardboard flap down for 1 second during packaging; the fail-safe spring return lifts the rod automatically if the factory air supply drops.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X100U with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X100U
To replace this MSAL25X100U, specify the MSBL25X100U and confirm the 25mm bore, 100mm stroke, G1/8 PT port, and flat U back cover. Because this SKU has no -S magnet, you cannot mount a sensor; if you need position detection, step up to an MSBL25X100S model and use the newer CMSG / DMSG / EMSG switches instead of the older CS1-M / DS1-M types. Maintain a minimum 0.2 MPa operating pressure to overcome the return spring.
For sizing flexibility, stepping down to a 20mm bore yields 106.8 N of push force at 0.5 MPa, while stepping up to a 32mm bore provides 317.7 N. Because this 100mm stroke is relatively long for a 25mm bore, ensure your mounting resists side-load to prevent rod bending and premature seal wear.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X100U (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X100U instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X100U FAQ
Yes, the MSAL25X100U is discontinued. The exact drop-in replacement is the MSBL25X100U, which matches the 25mm bore, 100mm stroke, G1/8 port, and flat U back cover. You will just need to update your switch family if you use sensors.
The usable push force is 176.4 N at 0.5 MPa and 274.5 N at 0.7 MPa (max 28 kgf). Because it is single-acting push with a return spring, the minimum operating pressure is 0.2 MPa to ensure the air can overcome the spring.
