This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15SCA 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 MSAL20X15SCA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X15SCA is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø20mm bore and 15mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15SCA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X15SCA
The AirTAC MSAL20X15SCA is a discontinued single-acting push cylinder with a 20mm bore and 15mm stroke. Air extends the rod to perform work, while an internal spring retracts it to a fail-safe home when air is removed. It delivers a usable push force of 106.8 N at 0.5 MPa. The exact drop-in replacement is the MSBL20X15SCA, matching the bore, stroke, G1/8 port, and CA clevis mount.
This SKU includes the -S magnet for position sensing with older CS1-M or DS1-M switches; the MSBL successor upgrades to CMSG, DMSG, or EMSG sensors. The original MSAL uses threaded covers, whereas the MSBL features a riveted rolling-packed body. End-of-stroke deceleration relies on a fixed rubber bumper, as no adjustable cushion exists on this series. Apply no external load on the spring return stroke to avoid bending the 8mm rod.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X15SCA Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL20X15SCA |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15SCA |
| Bore size | Ø20 mm |
| Stroke | 15 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15SCA 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 MSAL20X15SCA Is Used
PCB Ejector Pin
Pushes finished circuit boards out of a test fixture using 106.8 N at 0.5 MPa, relying on the spring to safely retract the 8mm pin when air drops.
Sensor Gate Diverter
Uses the -S magnet and CS1-M switch to confirm a 15mm stroke position, deflecting small electronic parts down a sorting chute.
Light Arcing Clamp
The CA clevis allows the body to swing on a pin, accommodating slight arc movement while holding a thin sheet metal bracket during a riveting step.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X15SCA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15SCA
To replace this MSAL20X15SCA, order the MSBL20X15SCA. Confirm your 20mm bore, 15mm stroke, PT G1/8 port, M8x1.25 rod thread, CA pivot clevis, and magnet requirement. Remember the minimum operating pressure is 0.2 MPa to overcome the return spring. If you need less force, there is no smaller bore in this series. If you need more force, step up to the 25mm bore, which provides 176.4 N of push at 0.5 MPa. With this short 15mm stroke, side-load risks are minimal, but always prevent external loads on the return stroke.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15SCA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15SCA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X15SCA FAQ
Yes, the MSAL20X15SCA is discontinued. The exact drop-in replacement is the MSBL20X15SCA, which matches the 20mm bore, 15mm stroke, G1/8 port, and CA clevis. You will only need to upgrade your position sensors from the older CS1-M or DS1-M to the newer CMSG, DMSG, or EMSG series.
The usable push force is 106.8 N at 0.5 MPa and 169.6 N at 0.7 MPa, with a maximum of 17.3 kgf. The operating pressure range is 0.2-1.0 MPa, with a 0.2 MPa minimum required to overcome the internal return spring.
