This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL25X85SCA, 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 MSAL25X85SCA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL25X85SCA is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø25mm bore and 85mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X85SCA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X85SCA
The AirTAC MSAL25X85SCA is a discontinued single-acting push cylinder where air extends the rod and an internal spring retracts it to a fail-safe home. It delivers 176.4 N of usable push force at 0.5 MPa. The direct replacement is the MSBL25X85SCA, matching the 25 mm bore, 85 mm stroke, G1/8 port, and CA mounting.
This SKU features a -S magnet for position sensing. The legacy MSAL uses older CS1-M or DS1-M reed switches, whereas the MSBL upgrade accepts CMSG, DMSG, or EMSG sensors. The MSAL body uses threaded covers, while the modern MSBL features a riveted rolling-packed body. Both generations use a fixed rubber bumper for end-of-stroke damping, meaning there is no adjustable cushion.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X85SCA Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL25X85SCA |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X85SCA |
| Bore size | Ø25 mm |
| Stroke | 85 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X85SCA 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 MSAL25X85SCA Is Used
Circuit Board Ejection
Pushes finished PCBs out of an SMT testing fixture with 176.4 N at 0.5 MPa; the spring return guarantees the ejector clears the bay if plant air drops.
Packaging Flap Guide
Extends to fold carton side flaps on a rotary packer; the CA clevis accommodates the arcing motion while the fixed bumper absorbs the stroke end impact.
Textile Loom Deflector
Extends 85 mm to route high-speed yarn threads to a secondary cone; the fail-safe retracted home prevents yarn tangles during an emergency air loss stop.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X85SCA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X85SCA
To replace this MSAL25X85SCA, install the MSBL25X85SCA. Confirm the 25 mm bore, 85 mm stroke, PT G1/8 port, M10x1.25 rod thread, CA pivot clevis, and the sensor family change (CS1-M/DS1-M to CMSG/DMSG/EMSG). Remember the 0.2 MPa minimum pressure required to overcome the return spring, and apply no external load on the return stroke.
If sizing a new application, step down to a 20 mm bore for 106.8 N push at 0.5 MPa, or step up to a 32 mm bore for 317.7 N at 0.5 MPa. Because this 85 mm stroke is relatively long for a 25 mm bore, watch for side-load and rod-bending forces during extension.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X85SCA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X85SCA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X85SCA FAQ
Yes, the MSAL25X85SCA is discontinued. The direct replacement is the MSBL25X85SCA, which matches the 25 mm bore, 85 mm stroke, CA clevis, G1/8 port, and single-acting push function. You will only need to update your sensors from the old CS1-M/DS1-M switches to the CMSG/DMSG/EMSG series.
The usable push force is 176.4 N at 0.5 MPa and 274.5 N at 0.7 MPa, with a maximum of roughly 28 kgf. The operating pressure range is 0.2-1.0 MPa; 0.2 MPa is the minimum because air pressure must overcome the internal return spring to extend the rod.
