This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X85SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X85SCA 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 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 drop-in 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 exact drop-in 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 exact drop-in 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.
