This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80SCM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80SCM 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 MSAL20X80SCM
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X80SCM 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80SCM.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X80SCM
The AirTAC MSAL20X80SCM 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. It delivers 106.8 N of usable push force at 0.5 MPa and requires a minimum operating pressure of 0.2 MPa to overcome the spring.
The exact drop-in replacement is the MSBL20X80SCM, matching the 20 mm bore, 80 mm stroke, G1/8 port, and CM round-end back cover. This MSAL features threaded covers and an -S magnet for older CS1-M or DS1-M switches. The MSBL upgrade shifts to a riveted rolling-packed body and uses CMSG, DMSG, or EMSG sensors.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X80SCM Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL20X80SCM |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80SCM |
| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80SCM 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 MSAL20X80SCM Is Used
PCB Ejector Pins
Uses the 106.8 N push force at 0.5 MPa to eject populated printed circuit boards from test fixtures, relying on the spring return to clear the workspace for the next panel.
Packaging Flap Deflectors
Extends 80 mm to hold cardboard flaps open during automated carton filling, with the fail-safe retracted home preventing jams if the air supply drops.
Connector Seating Stops
Acts as a hard stop for seating electronic connectors, where the fixed rubber bumper absorbs the impact and the spring return resets the stop without continuous air.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X80SCM with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80SCM
To replace this MSAL20X80SCM, install the MSBL20X80SCM. Confirm the 20 mm bore, 80 mm stroke, PT G1/8 port, M8x1.25 rod-end thread, CM round-end back cover, and the -S magnet. Remember that the MSBL requires CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M. Maintain the 0.2 MPa minimum pressure and apply no external load on the spring return stroke.
For sizing flexibility, stepping down is not an option as 20 mm is the smallest available bore. Stepping up to the 32 mm bore increases usable push force to 317.7 N at 0.5 MPa. Since this 80 mm stroke is relatively long for a 20 mm bore, carefully manage side loads to prevent rod bending.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80SCM (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80SCM instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X80SCM FAQ
Yes, the MSAL20X80SCM is discontinued. The exact drop-in replacement is the MSBL20X80SCM, which matches the 20 mm bore, 80 mm stroke, G1/8 port, and CM mounting. You will need to update your sensors, as the MSBL uses CMSG, DMSG, or EMSG switches instead of the older CS1-M/DS1-M type.
This single-acting push cylinder provides 106.8 N of usable force at 0.5 MPa and 169.6 N at 0.7 MPa. It requires a minimum operating pressure of 0.2 MPa to overcome the internal return spring. It uses a fixed rubber bumper for end-of-stroke cushioning and cannot hold a load mid-stroke without external mechanical locking.
