This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X75U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X75U 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 MSAL25X75U
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL25X75U is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø25mm bore and 75mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X75U.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X75U
The AirTAC MSAL25X75U 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 pressure drops. It delivers a usable push force of 176.4 N at 0.5 MPa and 274.5 N at 0.7 MPa. The direct drop-in replacement is the MSBL25X75U, matching the 25 mm bore, 75 mm stroke, G1/8 port, and U flat-end back cover.
This SKU lacks the -S magnet and cannot accept a position sensor. As an upgrade fact, the MSAL uses threaded covers and the older CS1-M/DS1-M switches, while the MSBL replacement features a riveted rolling-packed body and uses CMSG/DMSG/EMSG sensors. A fixed rubber bumper absorbs end-of-stroke impact, and a minimum air pressure of 0.2 MPa is required to overcome the return spring.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X75U Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL25X75U |

| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X75U 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 MSAL25X75U Is Used
PCB Router Ejector
Ejects routed circuit boards from a machining nest with 176.4 N at 0.5 MPa, relying on the spring return to retract the pin safely when air is cut.
Carton Flap Folder
Folds corrugated carton flaps on a packaging line; the U flat-end back cover mounts rigidly while the fixed rubber bumper absorbs the 75 mm stroke impact.
Bottle Divert Gate
Pushes a diverter arm to route plastic bottles on a conveyor, using the fail-safe retracted home to clear the path during an air-loss event.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X75U with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X75U
To replace the MSAL25X75U, specify the MSBL25X75U to match the 25 mm bore, 75 mm stroke, PT G1/8 port, U flat-end back cover, and no-magnet configuration. Remember the minimum operating pressure of 0.2 MPa. Apply no external load on the spring return stroke, as the spring drives the rod home but does not lock it. At 75 mm stroke on this compact bore, mind potential side loads that could cause rod-bending.
For sizing flexibility, step down to the 20 mm bore for lighter tasks (106.8 N push at 0.5 MPa) or step up to the 32 mm bore for heavier jobs (317.7 N push at 0.5 MPa). The 25 mm bore uses an Ø10 mm rod with an M10x1.25 rod-end thread.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X75U (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X75U instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X75U FAQ
Yes, the MSAL25X75U is discontinued. The exact drop-in replacement is the MSBL25X75U, which matches the 25 mm bore, 75 mm stroke, G1/8 port, and U back cover. The MSBL upgrades the body to a riveted rolling-packed design instead of threaded covers.
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 maximum force is about 28 kgf. It requires a minimum of 0.2 MPa to overcome the return spring.
