This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X150SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X150SCA 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 MSAL20X150SCA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X150SCA 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X150SCA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X150SCA
The AirTAC MSAL20X150SCA 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 on air loss. It delivers 106.8 N of usable push force at 0.5 MPa and requires a minimum of 0.2 MPa to overcome the return spring. The exact drop-in replacement is the MSBL20X150SCA, matching the 20 mm bore, 150 mm stroke, G1/8 port, and CA pivot cover.
This SKU includes the -S magnet, which pairs with older CS1-M or DS1-M reed switches. The MSBL upgrade moves to CMSG, DMSG, or EMSG sensors and replaces the MSAL's threaded covers with a riveted rolling-packed body. The CA back cover provides a pivot clevis that swings on a pin, making it ideal for arcing ejection motions. End-of-stroke energy is absorbed by a fixed rubber bumper, as no adjustable cushion exists in this series.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X150SCA Technical Specifications

| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X150SCA 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 MSAL20X150SCA Is Used
Stamping Press Ejector
Ejects small stamped metal parts from a die using 106.8 N of push force at 0.5 MPa. The spring-return fail-safe home guarantees the ejector rod clears the die if plant air drops.
Pivot Gate Diverter
Swings a lightweight pivot gate to sort small electronic components on a conveyor. The CA clevis back cover accommodates the arcing motion without binding the rod.
Packaging Flap Folder
Pushes cardboard flaps down during carton sealing. The fixed rubber bumper absorbs the 150 mm end-stroke impact, protecting the carton from denting.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X150SCA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X150SCA
To replace this MSAL20X150SCA, install the drop-in MSBL20X150SCA. Confirm the 20 mm bore, 150 mm stroke, PT G1/8 port, M8x1.25 rod-end thread, and CA pivot back cover. You must also update your sensors: the MSAL -S magnet uses CS1-M/DS1-M switches, while the MSBL uses CMSG/DMSG/EMSG. Maintain a 0.2-1.0 MPa operating pressure, and never apply an external load on the unpowered spring return stroke. At 150 mm stroke on a 20 mm bore, rod side-loading and bending risks are high, so ensure a rigid guide for the load.
If sizing a new layout, step down to a bore 20 unit if you need less force, or step up to bore 25, which provides 176.4 N of push at 0.5 MPa. The 150 mm stroke is the maximum standard length for these small bores; for longer travel, consider a double-acting MAL series.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X150SCA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X150SCA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X150SCA FAQ
Yes, the MSAL20X150SCA is discontinued. The exact drop-in replacement is the MSBL20X150SCA. It matches the 20 mm bore, 150 mm stroke, CA pivot cover, G1/8 port, and 106.8 N push force at 0.5 MPa. You only need to update your sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG.
The 20 mm bore single-acting push force is 106.8 N at 0.5 MPa and 169.6 N at 0.7 MPa (maximum 17.3 kgf). The operating pressure range is 0.2-1.0 MPa, with a 0.2 MPa minimum required to overcome the return spring and extend the rod.
