This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL20X15CM, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 direct 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 direct 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

| 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 direct 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.
