This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80SCA 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 MSAL20X80SCA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X80SCA is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø20mm bore and 80mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80SCA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X80SCA
The AirTAC MSAL20X80SCA is a discontinued single-acting push, spring-return mini cylinder. Air extends the 8 mm rod for the 80 mm stroke, while an internal spring retracts it to a fail-safe home on air loss. It delivers 106.8 N of usable push force at 0.5 MPa. The exact drop-in replacement is the MSBL20X80SCA, matching the 20 mm bore, G1/8 port, and CA clevis.
This SKU includes the -S magnet for position sensing, which uses the older CS1-M or DS1-M switches. The MSBL successor upgrades this to CMSG, DMSG, or EMSG sensors. The original MSAL features threaded covers, whereas the MSBL uses a riveted rolling-packed body. End-of-stroke damping relies on a fixed rubber bumper, meaning there is no adjustable cushion.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X80SCA Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL20X80SCA |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80SCA |
| Bore size | Ø20 mm |
| Stroke | 80 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80SCA 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 MSAL20X80SCA Is Used
PCB Ejector Pins
Uses the 106.8 N push force at 0.5 MPa to eject populated circuit boards from test fixtures, with the spring return ensuring pins retract safely if air drops.
Pivot Arm Diverter
Leverages the CA clevis back cover to swing a lightweight packaging diverter arm across a conveyor, accommodating the arcing load during the 80 mm stroke.
Small Part Stamper
Applies a brief 169.6 N impact at 0.7 MPa to emboss date codes on plastic bottle caps, relying on the fixed rubber bumper to absorb the end-stroke shock.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X80SCA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80SCA
To replace the MSAL20X80SCA, migrate to the MSBL20X80SCA and verify your 20 mm bore, 80 mm stroke, G1/8 PT thread, and CA pivot back cover. You must update your sensor inventory from CS1-M/DS1-M to CMSG/DMSG/EMSG. Ensure your air supply meets the 0.2 MPa minimum to overcome the return spring, and apply no external load on the return stroke. With an 80 mm stroke on a small 20 mm bore, watch for rod-bending side loads.
If you need to adjust sizing, step down to a 12 mm bore for lighter tasks, or step up to a 25 mm bore, which provides 176.4 N of push force at 0.5 MPa. The 20 mm bore yields 106.8 N at 0.5 MPa and 169.6 N at 0.7 MPa.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80SCA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80SCA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X80SCA FAQ
Yes, the MSAL20X80SCA is discontinued. The exact drop-in replacement is the MSBL20X80SCA, which matches the 20 mm bore, 80 mm stroke, G1/8 port, and CA mounting. You will need to upgrade your 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. The minimum operating pressure is 0.2 MPa because the air must overcome the internal return spring to extend the rod.
