This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X150CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X150CA 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 MSAL20X150CA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X150CA is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø20mm bore and 150mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X150CA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X150CA
The AirTAC MSAL20X150CA 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 requires a 3/2 valve and a minimum operating pressure of 0.2 MPa to overcome the return spring. The exact drop-in replacement is the MSBL20X150CA, matching the 20mm bore, 150mm stroke, G1/8 port, and CA pivot back cover.
This CA back cover swings on a pin to accommodate arcing loads. Because this SKU lacks the -S magnet, it cannot accept a position sensor. The MSAL features threaded covers and uses older CS1-M/DS1-M switches when equipped with a magnet, whereas the MSBL replacement upgrades to a riveted rolling-packed body and CMSG/DMSG/EMSG sensors. Usable push force is 106.8 N at 0.5 MPa and 169.6 N at 0.7 MPa. It uses a fixed rubber bumper for end-of-stroke damping, not an adjustable cushion.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X150CA Technical Specifications

| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X150CA 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 MSAL20X150CA Is Used
PCB Router Ejector
Pushes singulated circuit boards out of a routing fixture with 106.8 N at 0.5 MPa, relying on the spring return to clear the ejector pin before the next panel loads.
Pivot Gate Diverter
Swings a lightweight diverter flap on a packaging line using the CA pivot back cover, with the spring return safely pulling the gate to the home position on air loss.
Foam Pad Press
Compresses adhesive foam pads onto plastic housings, using the fixed rubber bumper to absorb the 150mm stroke impact without requiring adjustable cushioning.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X150CA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X150CA
To replace this MSAL20X150CA, order the MSBL20X150CA. Confirm the 20mm bore, 150mm stroke, PT G1/8 port, M8x1.25 rod-end thread, and CA pivot clevis. Since this SKU has no -S magnet, it cannot take a sensor; if you need sensing on the MSBL, add the -S and use CMSG/DMSG/EMSG switches. Maintain a 0.2 MPa minimum pressure and apply no external load on the spring return stroke.
For sizing, this 20mm bore yields 106.8 N of usable push at 0.5 MPa. If you need less force, there is no smaller standard bore in this series. If your application requires more force, step up to the 25mm bore, which provides 176.4 N at 0.5 MPa. Because this 150mm stroke is the maximum standard length for this small 8mm rod, verify side-load alignment to prevent rod-bending issues.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X150CA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X150CA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X150CA FAQ
Yes, the MSAL20X150CA is discontinued. The exact drop-in replacement is the MSBL20X150CA, which matches the 20mm bore, 150mm stroke, G1/8 port, and CA pivot back cover. The MSBL upgrades to a riveted rolling-packed body, but the force ratings and mounting dimensions remain the same.
The usable push force, already net of the return spring, is 12.6 N at 0.2 MPa, 75.4 N at 0.4 MPa, 106.8 N at 0.5 MPa, and 169.6 N at 0.7 MPa (max). The minimum operating pressure is 0.2 MPa because the air supply must overcome the internal return spring to extend the rod.
