This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL20X20CASDB, 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 MSAL20X20CASDB
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X20CASDB is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø20mm bore and 20mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X20CASDB.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X20CASDB
The AirTAC MSAL20X20CASDB is a discontinued 20mm bore, 20mm stroke single-acting push cylinder. Air extends the rod for work, while an internal spring retracts it to a fail-safe home on air loss. 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 MSBL20X20CASDB, matching the bore, stroke, G1/8 port, and SDB mounting.
This SKU includes a CA pivot back cover and an SDB pivot bracket for arcing loads. It has no -S magnet, so it cannot take a position sensor. The MSAL uses older threaded covers, while the MSBL upgrade features a riveted rolling-packed body. End-of-stroke damping is a fixed rubber bumper, not an adjustable cushion.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X20CASDB Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL20X20CASDB |

| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X20CASDB |
| Bore size | Ø20 mm |
| Stroke | 20 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X20CASDB 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 MSAL20X20CASDB Is Used
PCB Ejector
Pushes populated printed circuit boards out of a test fixture using 106.8 N at 0.5 MPa, relying on the spring return to clear the bay for the next panel.
Bag Flap Folder
Uses the CA pivot and SDB bracket to swing a packaging flap down during intermittent paper feed, safely returning home when air drops.
Wire Guide Stop
Acts as a hard stop for wire harness routing, holding the part with 169.6 N at 0.7 MPa before the spring retracts for the next cycle.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X20CASDB with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X20CASDB
To replace the MSAL20X20CASDB, install the MSBL20X20CASDB. Confirm the 20mm bore, 20mm stroke, G1/8 port, PT thread, CA pivot cover, and SDB bracket. Since this SKU lacks the -S magnet, it cannot accept a sensor; the MSBL also requires CMSG/DMSG/EMSG switches if you add the -S option later. Minimum operating pressure is 0.2 MPa to overcome the spring. Apply no external load on the return stroke.
If sizing force, the 20mm bore gives 106.8 N at 0.5 MPa. Stepping up to the 25mm bore yields 176.4 N at 0.5 MPa. Stepping down is not possible as 20mm is the smallest size. For a 20mm stroke on this compact body, ensure straight-line alignment to prevent side-load rod bending.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X20CASDB (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X20CASDB instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X20CASDB FAQ
Yes, the MSAL20X20CASDB is discontinued. The direct replacement is the MSBL20X20CASDB. It matches the 20mm bore, 20mm stroke, G1/8 port, CA pivot cover, and SDB bracket. 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. The maximum force is 169.6 N (17.3 kgf). Minimum operating pressure is 0.2 MPa because the air must overcome the internal return spring.
