This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X150SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X150SU 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 MSAL20X150SU
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X150SU is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø20mm bore and 150mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X150SU.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X150SU
The AirTAC MSAL20X150SU is a discontinued single-acting push, spring-return mini cylinder. Air extends the rod for the work stroke, while an internal spring retracts it to a fail-safe home when air is released. At bore 20, it yields a usable push force of 106.8 N at 0.5 MPa (169.6 N at 0.7 MPa). The exact drop-in replacement is the MSBL20X150SU, matching the 150 mm stroke, G1/8 port, and U back cover.
This SKU includes the -S magnet, which uses the older CS1-M / DS1-M switches; the MSBL replacement upgrades to CMSG / DMSG / EMSG sensors. The MSAL features threaded covers and a fixed rubber bumper, whereas the MSBL uses a riveted rolling-packed body. Apply no external load on the spring return stroke, as the spring only manages its own mass.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X150SU Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL20X150SU |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X150SU |
| Bore size | Ø20 mm |
| Stroke | 150 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X150SU 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 MSAL20X150SU Is Used
PCB ejection gate
Pushes finished printed circuit boards out of a test fixture using 106.8 N at 0.5 MPa, relying on the spring return to clear the gate for the next board.
Sensor arm reject
Extends a small reject flap on a chip conveyor; the fail-safe spring home ensures the flap retracts on air loss, preventing downstream pile-ups.
Light press pin
Drives a locating pin into a plastic housing assembly, where the fixed rubber bumper absorbs the end-of-stroke impact without needing adjustment.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X150SU with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X150SU
To replace the MSAL20X150SU with the MSBL20X150SU, confirm the 20 mm bore, 150 mm stroke, PT G1/8 port, U flat-end back cover, and M8x1.25 rod-end thread. You must also swap the CS1-M / DS1-M sensors for CMSG / DMSG / EMSG switches. Maintain a minimum 0.2 MPa operating pressure to beat the return spring, and never apply external load on the return stroke.
For sizing, stepping down to the 12 mm bore gives 45 N at 0.5 MPa, while stepping up to the 25 mm bore provides 176.4 N at 0.5 MPa. Because this 150 mm stroke is the maximum standard length for this small 8 mm rod, verify your guiding to prevent rod-bending side loads.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X150SU (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X150SU instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X150SU FAQ
Yes, the MSAL20X150SU is discontinued. The exact drop-in replacement is the MSBL20X150SU, which matches the 20 mm bore, 150 mm stroke, U back cover, and G1/8 port. You only need to upgrade the -S magnet sensors from CS1-M / DS1-M to CMSG / DMSG / EMSG.
The usable push force is 106.8 N at 0.5 MPa and 169.6 N at 0.7 MPa, with a maximum force of 17.3 kgf. It requires a minimum operating pressure of 0.2 MPa to overcome the return spring and extend the rod.
