This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X75SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X75SU 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 MSAL25X75SU
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL25X75SU 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X75SU.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X75SU
The AirTAC MSAL25X75SU is a discontinued single-acting push cylinder with a 25mm bore and 75mm stroke. Air extends the rod, 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 (274.5 N at 0.7 MPa). The exact drop-in replacement is the MSBL25X75SU, sharing the same force class, G1/8 port, and mounting footprint.
This U-back-cover SKU includes the -S magnet for position sensing. During the upgrade, the older CS1-M / DS1-M switches used on this threaded-body MSAL are replaced by CMSG / DMSG / EMSG switches on the riveted rolling-packed MSBL. A fixed rubber bumper absorbs end-of-stroke impact, as no adjustable cushion is present in this single-acting design.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X75SU Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL25X75SU |

| Bore size | Ø25 mm |
| Stroke | 75 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X75SU 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 MSAL25X75SU Is Used
PCB Router Ejection
Pushes singulated circuit boards out of a routing fixture with 176.4 N at 0.5 MPa; the spring return clears the path for the next panel without needing continuous air pressure.
Connector Insertion Press
Extends 75mm to seat a wire-to-board connector into a housing, relying on the fixed rubber bumper to stop the stroke safely before the spring retracts the rod.
Packaging Flap Deflector
Acts as a spring-return diverter gate on a carton sealing line, blocking a flap during the air stroke and snapping back to a fail-safe open home if compressed air drops.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X75SU with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X75SU
To replace this MSAL25X75SU, install the MSBL25X75SU after confirming the 25mm bore, 75mm stroke, PT G1/8 port, M10x1.25 rod thread, and U flat-end back cover. Remember the minimum operating pressure is 0.2 MPa to overcome the return spring, and never apply an external load on the spring return stroke. If sizing a new application, step down to a 20mm bore for 106.8 N push at 0.5 MPa, or step up to a 32mm bore for 317.7 N. At 75mm stroke on this compact body, watch for side-load and rod-bending forces.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X75SU (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X75SU instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X75SU FAQ
Yes, the MSAL25X75SU is discontinued. The exact drop-in replacement is the AirTAC MSBL25X75SU, which matches the 25mm bore, 75mm stroke, U back cover, and G1/8 port. You will only need to upgrade your position sensors, as the MSBL uses CMSG / DMSG / EMSG switches instead of the older CS1-M / DS1-M reed switches found on the MSAL.
The usable push force is 12.6 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 push force is roughly 28 kgf. The operating pressure range is 0.2-1.0 MPa, with a 0.2 MPa minimum required to overcome the internal return spring.
