This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL25X40SCM, 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 MSAL25X40SCM
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL25X40SCM is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø25mm bore and 40mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X40SCM.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X40SCM
The AirTAC MSAL25X40SCM is a discontinued single-acting push, spring-return mini cylinder. Air extends the rod for the 40 mm work stroke, and an internal spring retracts it, providing a fail-safe retracted home on air loss. It delivers a usable push force of 176.4 N at 0.5 MPa (274.5 N at 0.7 MPa) on its 25 mm bore.
The direct replacement is the MSBL25X40SCM, matching the bore, stroke, G1/8 port, and CM round-end cover. This MSAL features a -S magnet for CS1-M / DS1-M switches and threaded covers, whereas the MSBL upgrades to CMSG / DMSG / EMSG sensors and a riveted rolling-packed body. End-of-stroke energy is absorbed by a fixed rubber bumper, not an adjustable cushion.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X40SCM Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL25X40SCM |

| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X40SCM |
| Bore size | Ø25 mm |
| Stroke | 40 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X40SCM 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 MSAL25X40SCM Is Used
PCB Router Clamping
Holds a printed circuit board panel flat against a router fixture with 176.4 N of push force at 0.5 MPa, releasing automatically to a fail-safe home if compressed air drops.
Bottle Capper Ejection
Extends 40 mm to push tightened cosmetic bottles out of a capping spindle station, using the internal spring to retract instantly when the 3/2 valve cuts air.
Sorter Diverter Gate
Actuates a small pneumatic diverter on a conveyor for small electronic relays, locking position via the CS1-M sensor to confirm the push stroke completed.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X40SCM with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X40SCM
To replace this MSAL25X40SCM with the MSBL25X40SCM, confirm the 25 mm bore, 40 mm stroke, G1/8 PT port, M10x1.25 rod-end thread, CM round-end cover, and the -S magnet (noting the switch family changes from CS1-M / DS1-M to CMSG / DMSG / EMSG). Minimum operating pressure is 0.2 MPa to overcome the return spring, and no external load should be applied to the spring return stroke.
For sizing flexibility, stepping down to the 20 mm bore drops the 0.5 MPa push force to 106.8 N, while stepping up to the 32 mm bore raises it to 317.7 N. At 40 mm stroke on these small bores, keep the load axially aligned to prevent rod-bending side loads.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X40SCM (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X40SCM instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X40SCM FAQ
Yes, the MSAL25X40SCM is discontinued. The direct replacement is the MSBL25X40SCM, which matches the 25 mm bore, 40 mm stroke, G1/8 port, and CM mounting. You will only need to update your sensors, as the MSAL -S magnet uses older CS1-M / DS1-M switches while the MSBL uses CMSG / DMSG / EMSG switches.
The usable push force is 176.4 N at 0.5 MPa and 274.5 N at 0.7 MPa (max 28 kgf). Because it is single-acting push with a spring return, the minimum operating pressure is 0.2 MPa to ensure air can overcome the internal return spring. The spring provides a fail-safe retracted home, not a powered mid-stroke lock.
