This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL25X75SU, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 direct 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 direct 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 direct 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.
