This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X20CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X20CA 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 MSAL20X20CA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X20CA 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X20CA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X20CA
The AirTAC MSAL20X20CA 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. Bore 20mm yields 106.8N usable push at 0.5MPa. The exact drop-in replacement is the MSBL20X20CA, matching the bore, stroke, G1/8 port, and CA mounting.
This CA back cover is a pivot clevis that swings on a pin for arcing loads. The MSAL20X20CA uses threaded covers and a fixed rubber bumper, whereas the MSBL20X20CA upgrade features a riveted rolling-packed body. This SKU has no -S magnet and cannot take a position sensor. Minimum working pressure is 0.2MPa to overcome the return spring.

| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X20CA 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 MSAL20X20CA Is Used
PCB Ejector Pins
Pushes finished printed circuit boards out of an SMT pick-and-place fixture using 106.8N at 0.5MPa, relying on the spring return to retract the pin clear of the conveyor.
Wire Crimp Stop
Acts as a hard stop for a wire crimping head, applying up to 169.6N at 0.7MPa to halt the cycle, with the CA pivot absorbing any slight arcing misalignment.
Packaging Flap Folder
Extends to fold cardboard carton flaps during a packaging line transition, using the fail-safe spring return to guarantee the folder retracts on air loss.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X20CA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X20CA
To replace the MSAL20X20CA, order the MSBL20X20CA. Confirm the 20mm bore, 20mm stroke, G1/8 PT port, M8x1.25 rod, and CA pivot back cover are retained. The MSBL20X20CA is a true drop-in upgrade. Since this SKU lacks the -S magnet, it cannot accept a sensor; if you need position detection on the new MSBL, add the -S suffix to use CMSG/DMSG/EMSG switches (the older MSAL used CS1-M/DS1-M).
For sizing, step down is unavailable as 20mm is the smallest bore. Stepping up to the 32mm bore yields 317.7N at 0.5MPa. Maintain a 0.2MPa minimum supply pressure. Apply NO external load on the spring return stroke, as the return force is small and unpowered. At 20mm stroke, side-load and rod-bending risks are minimal.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X20CA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X20CA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X20CA FAQ
Yes, the MSAL20X20CA is discontinued. The exact drop-in replacement is the MSBL20X20CA, which matches the 20mm bore, 20mm stroke, G1/8 port, and CA pivot cover. The MSBL20X20CA upgrades the body to a riveted rolling-packed design.
The usable push force is 12.6N at 0.2MPa, 106.8N at 0.5MPa, and 169.6N at 0.7MPa (max 17.3 kgf). These forces are net of the opposing return spring. A minimum air pressure of 0.2MPa is required to overcome the spring and extend the rod.
