This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X20CASDB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X20CASDB 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 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 drop-in 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 exact drop-in 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 exact drop-in 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.
