This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X90CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X90CA 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 MSAL25X90CA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL25X90CA is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø25mm bore and 90mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X90CA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X90CA
The AirTAC MSAL25X90CA is a discontinued single-acting push, spring-return mini cylinder. Air extends the 25mm bore rod for the 90mm work stroke, while an internal spring retracts it to a fail-safe home on air loss. It delivers 176.4 N of usable push force at 0.5 MPa and 274.5 N at 0.7 MPa. The exact drop-in replacement is the MSBL25X90CA, which matches the bore, stroke, G1/8 port, and CA pivot back cover.
This CA-coded SKU features a pivot clevis back cover that swings on a pin to accommodate arcing loads. It has no -S magnet and cannot accept a position sensor. The older MSAL uses threaded covers and CS1-M/DS1-M switches, while the MSBL upgrade features a riveted rolling-packed body and CMSG/DMSG/EMSG sensors. End-of-stroke damping relies on a fixed rubber bumper, not an adjustable cushion.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X90CA Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL25X90CA |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X90CA |
| Bore size | Ø25 mm |
| Stroke | 90 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X90CA 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 MSAL25X90CA Is Used
PCB Router Ejector
Pushes cut printed circuit boards out of a routing fixture with 176.4 N at 0.5 MPa, relying on the spring return to retract the pin clear of the next panel.
Pivot-Link Clamp
Uses the CA clevis back cover to swing an arcing hold-down arm onto aluminum extrusions, with the fail-safe home releasing the clamp on air loss.
Bottle Sorting Gate
Strokes 90mm to deflect glass bottles on a conveyor line, where the fixed rubber bumper absorbs the stop impact without requiring adjustment.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X90CA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X90CA
To replace this MSAL25X90CA, order the MSBL25X90CA. Confirm the 25mm bore, 90mm stroke, G1/8 PT thread, and CA pivot back cover. Because this SKU lacks the -S magnet, it cannot hold a sensor; if you need position detection on the new MSBL, add the -S suffix and switch to CMSG/DMSG/EMSG switches. Maintain a 0.2 MPa minimum air pressure to overcome the return spring, and apply no external load on the return stroke.
For sizing flexibility, stepping down to the 20mm bore drops usable push to 106.8 N at 0.5 MPa, while stepping up to the 32mm bore increases it to 317.7 N. With a 90mm stroke on this compact 25mm bore, minimize side loads to prevent rod bending.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X90CA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X90CA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X90CA FAQ
Yes, the MSAL25X90CA is discontinued. The exact drop-in replacement is the MSBL25X90CA, which matches the 25mm bore, 90mm stroke, G1/8 port, and CA pivot back cover. You only need to update the sensor family if you use one.
The 25mm bore single-acting push force is 176.4 N at 0.5 MPa and 274.5 N at 0.7 MPa. The minimum operating pressure is 0.2 MPa to overcome the internal return spring.
