This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X110U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X110U 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 MSAL25X110U
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL25X110U is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø25mm bore and 110mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X110U.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X110U
The AirTAC MSAL25X110U is a discontinued single-acting push, spring-return mini cylinder. Air extends the rod for the work stroke, and 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 MSBL25X110U, matching the 25 mm bore, 110 mm stroke, G1/8 port, and U flat-end back cover.
This non-magnet SKU cannot accept a position sensor. As an upgrade fact, the MSAL uses older CS1-M/DS1-M switches and threaded covers, while the MSBL replacement uses CMSG/DMSG/EMSG sensors and a riveted rolling-packed body. A fixed rubber bumper absorbs end-of-stroke impact, and the hard-chrome carbon-steel rod resists wear.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X110U Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL25X110U |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X110U |
| Bore size | Ø25 mm |
| Stroke | 110 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X110U 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 MSAL25X110U Is Used
PCB Router Ejector
Pushes freshly milled circuit boards from a router bed with 176.4 N at 0.5 MPa, relying on the spring return to clear the workspace before the next cycle.
Packaging Flap Deflector
Extends to hold a cardboard carton flap during case packing, then releases to a fail-safe home on air loss so the line does not jam.
Stamping Pin Withdrawal
Drives a small marking pin into thin aluminum tags; the fixed rubber bumper stops the stroke, and the spring safely pulls the pin back out.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X110U with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X110U
To replace the MSAL25X110U, install the drop-in MSBL25X110U. Confirm the 25 mm bore, 110 mm stroke, G1/8 port, PT thread, U flat-end back cover, and lack of a magnet (no sensor). Remember the 0.2 MPa minimum operating pressure required to overcome the return spring, and apply no external load on the return stroke.
For sizing flexibility, stepping down to the 20 mm bore yields 106.8 N at 0.5 MPa, while stepping up to the 32 mm bore provides 317.7 N at 0.5 MPa. Because this 110 mm stroke is long for a small bore, prevent side loads to avoid rod bending and premature guide wear.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X110U (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X110U instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X110U FAQ
Yes, the MSAL25X110U is discontinued. The exact drop-in replacement is the MSBL25X110U, which matches the 25 mm bore, 110 mm stroke, G1/8 port, and U flat-end back cover. The MSBL upgrades the body to a riveted rolling-packed design.
The usable push force is 29.2 N at 0.2 MPa, 78.3 N at 0.3 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 operating pressure range is 0.2-1.0 MPa, requiring a minimum of 0.2 MPa to beat the return spring.
