This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15CM 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 MSAL20X15CM
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X15CM 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15CM.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X15CM
The AirTAC MSAL20X15CM is a discontinued single-acting push cylinder with a 20mm bore and 15mm stroke. Air extends the rod to do 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 MSBL20X15CM, matching the bore, stroke, G1/8 port, and CM round-end cover.
This SKU has no -S magnet and cannot accept a position sensor. As a mini cylinder, it uses a fixed rubber bumper rather than an adjustable cushion. Note the construction upgrade: this MSAL has threaded covers, while the MSBL replacement features a riveted rolling-packed body. Apply no external load on the spring return stroke to prevent bending the 8mm rod.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X15CM Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL20X15CM |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15CM |
| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15CM 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 MSAL20X15CM Is Used
PCB Ejector Pin
Pushes bare logic boards out of a test fixture using 106.8 N at 0.5 MPa, relying on the spring return to retract the 8mm rod safely between cycles.
Connector Sorting Gate
Diverts small plastic connectors on a conveyor line; the fail-safe home position prevents jams during an air loss event on the 15mm stroke.
Light Part Stamper
Applies a 169.6 N impact at 0.7 MPa to stamp date codes on thin aluminum tags, with the fixed rubber bumper absorbing the end-of-stroke shock.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X15CM with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15CM
To replace this MSAL20X15CM, migrate to the MSBL20X15CM. Confirm the 20mm bore, 15mm stroke, PT G1/8 port, M8x1.25 rod thread, and CM round-end cover. Because this SKU lacks the -S magnet, you lose position sensing entirely; if you need sensing, step up to an MSBL20X15SCM and use the newer CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M. Remember the 0.2 MPa minimum pressure required to overcome the return spring.
For sizing, this 20mm bore provides 106.8 N at 0.5 MPa and 169.6 N at 0.7 MPa. If you need less force, there is no smaller standard MAL bore, so you must reduce pressure. If you need more force, step up to the 25mm bore, which provides 176.4 N at 0.5 MPa. With the short 15mm stroke, side-load risk is minimal, but always ensure the CM cover aligns with your mounting plane.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15CM (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15CM instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X15CM FAQ
Yes, the MSAL20X15CM is discontinued. The exact drop-in replacement is the MSBL20X15CM, which matches the 20mm bore, 15mm stroke, G1/8 port, and CM round-end cover. The MSBL upgrades the body to a riveted rolling-packed design instead of threaded covers.
The usable push force is 106.8 N at 0.5 MPa and 169.6 N at 0.7 MPa. The maximum force is 169.6 N (17.3 kgf). Because it is single-acting push with a spring return, the minimum operating pressure is 0.2 MPa to overcome the internal spring.
