This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X60U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X60U 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 MSAL20X60U
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X60U is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø20mm bore and 60mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X60U.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X60U
The AirTAC MSAL20X60U is a discontinued single-acting push, spring-return mini cylinder. Air extends the 8 mm rod for the 60 mm stroke, while an internal spring retracts it to a fail-safe home when air is released. The exact drop-in replacement is the MSBL20X60U, matching the 20 mm bore, G1/8 port, and U flat-end back cover. This U-groove cover provides a rigid, flush rear mounting face.
At 20 mm bore, this SKU delivers a usable push force of 106.8 N at 0.5 MPa (169.6 N at 0.7 MPa), already net of the return spring. It features a fixed rubber bumper for end-of-stroke damping and a carbon-steel rod with 20 um hard chrome. Because this specific code lacks the -S suffix, it has no magnet and cannot accept a position sensor. The legacy MSAL uses threaded covers and CS1-M switches, whereas the MSBL upgrade features a riveted rolling-packed body and CMSG sensors.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X60U Technical Specifications

| Bore size | Ø20 mm |
| Stroke | 60 mm |
| Acting type | Single acting, push (spring return) |
| Port size | G1/8 |
| Rod thread | M8×1.25 |
| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X60U carries the same single-acting ratings.
Usable Push Force (Ø20mm)
| Pressure | Push force (net of spring) |
|---|---|
| 0.5 MPa | 106.8 N |
| 0.7 MPa | 169.6 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 MSAL20X60U Is Used
PCB Router Ejector
Pushes singulated circuit boards out of a router fixture with 106.8 N at 0.5 MPa, relying on the spring return to clear the workspace for the next panel.
Light Film Gate
Actuates a thin packaging film diverter gate; the fail-safe spring home opens the gate on air loss to prevent film tearing jams.
Aluminum Extrusion Clamp
Holds a 20 mm aluminum profile against a manual saw stop. The fixed rubber bumper absorbs the 60 mm stroke impact without marking the soft metal.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X60U with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X60U
To replace the MSAL20X60U with the MSBL20X60U, confirm the 20 mm bore, 60 mm stroke, G1/8 PT port, M8x1.25 rod-end thread, and the flat U back cover. The minimum working pressure is 0.2 MPa to overcome the spring. Never apply an external load on the spring return stroke, as the retraction force is small and unpowered. For a 60 mm stroke on this compact bore, verify guide alignment to prevent rod-bending side loads.
If sizing force, stepping down is not an option as 20 mm is the smallest bore. Stepping up to the 32 mm bore provides a 317.7 N push at 0.5 MPa if you need higher clamping pressure. The MSBL20X60U is a direct physical drop-in, but note the sensor family changes from CS1-M to CMSG if you later need a magnet-equipped variant.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X60U (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X60U instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X60U FAQ
Yes, the MSAL20X60U is discontinued. The exact drop-in replacement is the MSBL20X60U, which matches the 20 mm bore, 60 mm stroke, G1/8 port, and U flat-end cover. The MSBL upgrades the body to a riveted rolling-packed design but maintains the same force class.
The usable push force (net of the return spring) is 12.6 N at 0.2 MPa, 106.8 N at 0.5 MPa, and 169.6 N at 0.7 MPa (max 17.3 kgf). The minimum operating pressure is 0.2 MPa because the air pressure must overcome the internal return spring to extend the rod.
