This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL25X30SU, 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 MSAL25X30SU
The AirTAC MSAL Front Single Acting Compact Cylinder MSAL25X30SU is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø25mm bore and 30mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X30SU.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X30SU
The AirTAC MSAL25X30SU is a discontinued single-acting push, spring-return mini cylinder. Air extends the 25mm bore rod for a 30mm stroke, while an internal spring retracts it to a fail-safe home on air loss, requiring only a 3/2 valve and a 0.2 MPa minimum pressure. It delivers a usable push force of 176.4 N at 0.5 MPa. The direct replacement is the MSBL25X30SU, retaining the same bore, stroke, G1/8 port, and U flat-end back cover.
This SKU includes the -S magnet, which pairs with the older CS1-M / DS1-M switches; the MSBL successor upgrades to CMSG / DMSG / EMSG sensors. The legacy MSAL body uses threaded covers, whereas the MSBL features a riveted rolling-packed body. Both generations use a fixed rubber bumper for end-of-stroke damping and cannot hold a load mid-stroke.

| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X30SU 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 MSAL25X30SU Is Used
PCB Ejector Station
Pushes finished printed circuit boards out of a test fixture with 176.4 N at 0.5 MPa; the spring return guarantees the ejector pin clears the lane during a pneumatic power loss.
Small Part Sorter Gate
Acts as a diverter arm for electronic components on a conveyor, using the 30mm stroke to extend and block parts before the internal spring safely retracts the barrier.
Light-Duty Staking Press
Provides 274.5 N of push force at 0.7 MPa to seat small connector pins into plastic housings, relying on the fixed rubber bumper to absorb the end-stop impact.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X30SU with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X30SU
To replace the MSAL25X30SU, order the MSBL25X30SU and confirm the 25mm bore, 30mm stroke, G1/8 PT port, U flat-end back cover, and -S magnet. Remember the sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG. Maintain the 0.2 MPa minimum operating pressure to overcome the return spring, and apply no external load on the return stroke.
For sizing flexibility, stepping down to the 20mm bore yields 106.8 N of push force at 0.5 MPa, while stepping up to the 32mm bore provides 317.7 N at 0.5 MPa. The 30mm stroke is short enough to avoid rod-bending side-load issues, but always ensure rigid mounting via the U back cover.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X30SU (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X30SU instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X30SU FAQ
Yes, the MSAL25X30SU is discontinued. The direct replacement is the MSBL25X30SU, which matches the 25mm bore, 30mm stroke, G1/8 port, U back cover, and -S magnet. The MSBL upgrades the body to a riveted rolling-packed design and uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M.
The 25mm bore single-acting push force is 29.2 N at 0.2 MPa, 127.4 N at 0.4 MPa, 176.4 N at 0.5 MPa, and 274.5 N at 0.7 MPa (maximum). It requires a 0.2-1.0 MPa air supply to beat the return spring, operates at 50-800 mm/s, and uses a fixed rubber bumper.
