This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL25X25SCM, 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 MSAL25X25SCM
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL25X25SCM is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø25mm bore and 25mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X25SCM.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X25SCM
The AirTAC MSAL25X25SCM is a discontinued single-acting push mini cylinder with a 25 mm bore and 25 mm stroke. Air extends the rod for work, while an internal spring retracts it to a fail-safe home on air loss. The direct replacement is the MSBL25X25SCM, sharing the same force, G1/8 port, and CM mounting. This bore delivers a usable push force of 176.4 N at 0.5 MPa and 274.5 N at 0.7 MPa.
This SKU includes the -S magnet for position sensing, originally using CS1-M or DS1-M switches; the MSBL upgrade transitions to CMSG, DMSG, or EMSG sensors. The MSAL features threaded covers and a fixed rubber bumper, whereas the MSBL uses a riveted rolling-packed body. Minimum operating pressure is 0.2 MPa to overcome the return spring, and you must apply no external load on the return stroke.

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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X25SCM 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 MSAL25X25SCM Is Used
PCB Ejector Pins
Uses the 176.4 N push force at 0.5 MPa to positively eject populated circuit boards from test fixtures, with the spring ensuring a safe retracted home when air is removed.
Sensor Gate Diverter
The CS1-M reed switch feedback tracks the 25 mm stroke to confirm gate position on a chip-feeding conveyor, diverting parts only when the rod is fully extended.
Light Assembly Press
Presses small plastic clips into housings using the 274.5 N available at 0.7 MPa, relying on the fixed rubber bumper to absorb the end-of-stroke impact without adjustment.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X25SCM with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X25SCM
To replace the MSAL25X25SCM, install the direct replacement MSBL25X25SCM, confirming the 25 mm bore, 25 mm stroke, PT G1/8 port, CM round-end back cover, and -S magnet. Remember the sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG, and ensure your air supply meets the 0.2 MPa minimum. Never apply external load on the spring return stroke.
For sizing flexibility, stepping down to the 20 mm bore drops your push force to 106.8 N at 0.5 MPa, while stepping up to the 32 mm bore increases it to 317.7 N at 0.5 MPa. Even at a 25 mm stroke on these compact bores, mind potential side-load and rod-bending forces during ejection.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X25SCM (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X25SCM instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X25SCM FAQ
Yes, the MSAL25X25SCM is discontinued. The direct replacement is the MSBL25X25SCM, which matches the 25 mm bore, 25 mm stroke, G1/8 port, CM cover, and single-acting push function. You only need to update your sensors from the older CS1-M/DS1-M switches to the CMSG/DMSG/EMSG family.
The 25 mm 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, 225.5 N at 0.6 MPa, and 274.5 N at 0.7 MPa (max 27.9 kgf). The absolute minimum operating pressure is 0.2 MPa because the air must overcome the internal return spring.
