This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL20X30U, 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 MSAL20X30U
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X30U is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø20mm bore and 30mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30U.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X30U
The AirTAC MSAL20X30U is a discontinued single-acting push mini cylinder. Air extends the rod for the 30 mm work stroke, while an internal spring retracts it to a fail-safe home when air drops. It yields a usable push force of 106.8 N at 0.5 MPa (169.6 N at 0.7 MPa). The direct replacement is the MSBL20X30U, matching the 20 mm bore, stroke, G1/8 port, and U flat-end cover.
This SKU lacks the -S magnet and cannot take a position sensor. The older MSAL uses threaded covers and CS1-M / DS1-M switches, whereas the MSBL replacement features a riveted rolling-packed body and CMSG / DMSG / EMSG sensors. It relies on a fixed rubber bumper for end-of-stroke damping, not an adjustable cushion. Never apply external load on the spring return stroke.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X30U Technical Specifications

| Bore size | Ø20 mm |
| Stroke | 30 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30U 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 MSAL20X30U Is Used
PCB Ejector Pins
Pushes delicate printed circuit boards out of an assembly fixture with 106.8 N at 0.5 MPa, using the spring return to safely retract the pin when air is cut.
Light Stamping Press
Provides a compact 30 mm stamping stroke for thin foil packaging, relying on the fixed rubber bumper to absorb the impact at the end of the push stroke.
Pneumatic Diverter Flap
Actuates a lightweight routing gate on a small-parts conveyor, where the spring-return fail-safe home automatically clears the lane on air loss.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X30U with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30U
To replace the MSAL20X30U with an MSBL20X30U, confirm the 20 mm bore, 30 mm stroke, G1/8 PT port, and U flat-end back cover. This non-magnet SKU cannot hold a sensor, but if you previously used an -S variant, note the switch family changes from CS1-M / DS1-M to CMSG / DMSG / EMSG. Ensure your air supply meets the 0.2 MPa minimum to beat the return spring.
If sizing force, stepping down is not an option as 20 mm is the smallest bore. Stepping up to the 32 mm bore gives 317.7 N at 0.5 MPa. With a 30 mm stroke on this compact body, rod-bending side loads are minimal, but always avoid lateral loads on the spring return.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30U (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30U instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X30U FAQ
Yes, the MSAL20X30U is discontinued. The direct replacement is the MSBL20X30U, which matches the 20 mm bore, 30 mm stroke, G1/8 port, and U flat-end cover. The MSBL upgrades the body to a riveted rolling-packed design.
The usable push force is 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 must overcome the internal return spring to extend the rod.
