This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80U 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 MSAL20X80U
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X80U 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80U.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X80U
The AirTAC MSAL20X80U is a discontinued single-acting push cylinder with an 80 mm stroke and 20 mm bore. Air extends the rod to do work, while an internal spring retracts it to a fail-safe home when pressure drops. It delivers 106.8 N of usable push force at 0.5 MPa. The exact drop-in replacement is the MSBL20X80U, matching the bore, stroke, U back cover, and G1/8 port.
This U-coded SKU features a flat-end rear cover for rigid mounting. Because it lacks the -S magnet, it cannot accept a position sensor. The original MSAL body uses threaded covers and the older CS1-M / DS1-M switches, whereas the MSBL upgrade features a riveted rolling-packed body and CMSG / DMSG / EMSG sensors. End-of-stroke deceleration relies on a fixed rubber bumper, as there is no adjustable cushion.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X80U Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL20X80U |

| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80U |
| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80U 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 MSAL20X80U Is Used
PCB Ejector Pins
Pushes finished circuit boards out of test fixtures with 106.8 N at 0.5 MPa, relying on the spring return to clear the area for the next board.
Light-Duty Stamping Guard
Acts as a safety gate interlock on a small pneumatic press, using the fail-safe retracted home to block access instantly upon air loss.
Packaging Flap Deflector
Extends 80 mm to guide cardboard carton flaps during case erecting, retracting automatically to allow box passage without a complex 5/2 valve.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X80U with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80U
To replace this MSAL20X80U, order the MSBL20X80U. Confirm the 20 mm bore, 80 mm stroke, G1/8 PT port, M8x1.25 rod thread, and flat U back cover. Remember the 0.2 MPa minimum operating pressure required to overcome the return spring, and apply no external load on the return stroke. Stepping down is not an option as 20 mm is the smallest available size. If you need more force, step up to the 25 mm bore, which provides 176.4 N of push at 0.5 MPa. For an 80 mm stroke on these small bores, ensure your mounting prevents side-load and rod-bending forces.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80U (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80U instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X80U FAQ
Yes, the MSAL20X80U is discontinued. The exact drop-in replacement is the MSBL20X80U, which matches the 20 mm bore, 80 mm stroke, G1/8 port, and U back cover. The MSBL upgrades the body to a riveted rolling-packed design.
This single-acting push cylinder delivers 106.8 N at 0.5 MPa and 169.6 N at 0.7 MPa (about 17.3 kgf). The minimum operating pressure is 0.2 MPa, which is required to overcome the internal return spring before the rod can extend.
