This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL25X35U, 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 MSAL25X35U
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL25X35U is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø25mm bore and 35mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X35U.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X35U
The AirTAC MSAL25X35U is a discontinued single-acting push cylinder with a 25mm bore and 35mm stroke. Air extends the rod, while an internal spring retracts it to a fail-safe home when pressure drops. It delivers a usable push force of 176.4 N at 0.5 MPa. The direct replacement is the MSBL25X35U, matching the bore, stroke, G1/8 port, and U flat-end back cover.
This U-cover SKU lacks the -S magnet option, meaning it cannot accept a position sensor. Upgrading to the MSBL25X35U moves you from threaded covers to a riveted rolling-packed body. The original fixed rubber bumper absorbs end-of-stroke impact without adjustable cushioning. Remember that the return spring provides a small retraction force only; apply no external load on the return stroke.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X35U Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL25X35U |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X35U |
| Bore size | Ø25 mm |
| Stroke | 35 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X35U 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 MSAL25X35U Is Used
PCB Ejector Pin
Pushes bare printed circuit boards out of a test fixture using 176.4 N at 0.5 MPa, relying on the spring return to retract the pin safely during board loading.
Packaging Flap Deflector
Extends to hold a cardboard carton flap clear during product drop, then spring-retracts to a fail-safe home when air is removed to allow carton transit.
Light-Part Sorting Gate
Diverts small plastic injection-moulded parts down a conveyor chute; the single-acting push design requires only one 3/2 valve to actuate the gate.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X35U with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X35U
To replace this MSAL25X35U with the MSBL25X35U, verify your 25mm bore, 35mm stroke, PT G1/8 port, M10x1.25 rod-end thread, and the rigid U flat-end back cover. Because this SKU has no -S magnet, you lose position sensing; if you need a sensor on the MSBL, add the -S suffix and switch to the modern CMSG/DMSG/EMSG switches (the MSAL used older CS1-M/DS1-M). Maintain a minimum 0.2 MPa operating pressure to overcome the return spring.
If sizing a new application, step down to the 20mm bore for 106.8 N push at 0.5 MPa, or step up to the 32mm bore for 317.7 N at 0.5 MPa. With a 35mm stroke on these small bores, side-load and rod-bending risks are low, but always ensure the load is axially aligned.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X35U (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X35U instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X35U FAQ
Yes, the MSAL25X35U is discontinued. The direct replacement is the MSBL25X35U, which matches the 25mm bore, 35mm stroke, G1/8 port, and U flat-end back cover. You will move from threaded covers to a riveted rolling-packed body.
The usable push force is 29.2 N at 0.2 MPa, 176.4 N at 0.5 MPa, and 274.5 N at 0.7 MPa. The minimum operating pressure is 0.2 MPa because the air pressure must overcome the internal return spring to extend the rod.
