This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X15SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X15SU 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 MSAL25X15SU
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL25X15SU is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø25mm bore and 15mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X15SU.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X15SU
The AirTAC MSAL25X15SU is a discontinued single-acting push, spring-return mini cylinder. Air extends the rod for the 15mm work stroke, and an internal spring retracts it when air is released, 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). The exact drop-in replacement is the MSBL25X15SU, matching the 25mm bore, 15mm stroke, G1/8 port, and U flat-end back cover.
This SKU includes the -S magnet for position sensing. On the MSAL, the magnet works with the older CS1-M / DS1-M switches, whereas the MSBL replacement uses the modern CMSG / DMSG / EMSG family. The MSAL features threaded covers and a fixed rubber bumper, while the MSBL upgrade utilizes a riveted rolling-packed body. Apply no external load on the spring return stroke to avoid damaging the internal mechanism.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X15SU Technical Specifications

| Stroke | 15 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X15SU 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 MSAL25X15SU Is Used
PCB Ejector Station
Uses the 176.4 N push force at 0.5 MPa to eject finished circuit boards from an SMT conveyor, relying on the spring return to clear the workspace during downtime.
Packaging Flap Tucking
Tucks carton flaps on a packaging line where the 15mm stroke is sufficient, and the fail-safe retracted home prevents jams during an air loss event.
Textile Loom Diverter
Acts as a short-stroke thread diverter on a textile loom, using the G1/8 port and 50-800 mm/s speed range to rapidly shift yarn guides with a single 3/2 valve.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X15SU with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X15SU
To replace the MSAL25X15SU, select the MSBL25X15SU and confirm the 25mm bore, 15mm stroke, PT G1/8 port, U flat-end back cover, and -S magnet. Remember the sensor family changes from CS1-M / DS1-M to CMSG / DMSG / EMSG. The system needs a 3/2 valve and a minimum 0.2 MPa operating pressure to overcome the return spring. Never apply an external load on the spring return stroke.
For sizing both ways: if you need less push force, step down to the 20mm bore (106.8 N at 0.5 MPa); if you need more force, step up to the 32mm bore (317.7 N at 0.5 MPa). The 15mm stroke is short, keeping rod bending stress low, but always ensure the load is axially aligned to prevent side-load wear on the self-lubricating front-cover guide.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X15SU (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X15SU instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X15SU FAQ
Yes, the MSAL25X15SU is discontinued. The exact drop-in replacement is the MSBL25X15SU, which matches the 25mm bore, 15mm stroke, G1/8 port, U back cover, and single-acting push function. You only need to update your sensors from the older CS1-M / DS1-M to the modern CMSG / DMSG / EMSG family.
The usable push force is 176.4 N at 0.5 MPa and 274.5 N at 0.7 MPa (maximum 274.5 N, roughly 28 kgf). The minimum operating pressure is 0.2 MPa because the air must overcome the internal return spring to extend the rod.
