This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X150CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X150CM 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 MSAL20X150CM
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X150CM 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X150CM.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X150CM
The AirTAC MSAL20X150CM is a discontinued single-acting push cylinder with a 20 mm bore and 150 mm stroke. Air extends the rod for the work stroke, while an internal spring retracts it to a fail-safe home when air is removed. 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 return spring. The exact drop-in replacement is the MSBL20X150CM, which matches the bore, stroke, G1/8 port, and CM round-end cover.
Because this SKU lacks the -S suffix, it cannot accept a position sensor. As an upgrade note, the MSAL uses threaded covers and older CS1-M or DS1-M switches, whereas the MSBL replacement features a riveted rolling-packed body and uses CMSG, DMSG, or EMSG sensors. The cylinder relies on a fixed rubber bumper for end-of-stroke damping and uses a PT tapered port thread form.

| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X150CM 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 MSAL20X150CM Is Used
PCB Router Ejector
Utilizes the 106.8 N push force at 0.5 MPa to eject cut printed circuit boards from a routing machine, with the spring return ensuring the ejector retracts clear of the spindle during cuts.
Lightweight Parts Diverter
Pushes small plastic injection-molded components down a packaging line chute, relying on the 150 mm stroke to clear the conveyor belt before the fail-safe spring pulls the gate back.
Tester Contact Probe
Extends a spring-loaded test probe into an electrical connector socket, using the 20 mm bore compact size to fit within tight automated test handler spacing.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X150CM with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X150CM
To replace this MSAL20X150CM, order the MSBL20X150CM. Confirm the 20 mm bore, 150 mm stroke, G1/8 port, PT thread, and CM round-end cover are correct for your mount. Since this SKU has no -S magnet, it cannot take a sensor; if you need position feedback, step up to an MSBL20X150CMS and use CMSG, DMSG, or EMSG switches. Maintain a 0.2 MPa minimum air pressure to ensure the cylinder extends, and apply no external load on the spring return stroke for safety.
If you need to adjust your force output, stepping down is not an option as 20 mm is the smallest available bore. Stepping up to the 32 mm bore yields 317.7 N of push force at 0.5 MPa, providing a much higher capacity if your fixture requires it. Because this 150 mm stroke is the maximum standard length for this small 20 mm bore, be mindful of potential side-load and rod-bending issues during operation.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X150CM (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X150CM instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X150CM FAQ
Yes, the MSAL20X150CM is discontinued. The exact drop-in replacement is the MSBL20X150CM, which matches the 20 mm bore, 150 mm stroke, G1/8 port, and CM cover. The MSBL uses a riveted rolling-packed body instead of threaded covers, but the force class and mounting remain the same.
The MSAL20X150CM provides 106.8 N of usable push force at 0.5 MPa and 169.6 N at 0.7 MPa. The operating pressure range is 0.2-1.0 MPa, with a 0.2 MPa minimum required to overcome the return spring. The maximum push force is approximately 17.3 kgf.
