This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15U 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 MSAL20X15U
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X15U 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15U.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X15U
The AirTAC MSAL20X15U 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. This 20mm bore delivers a usable push force of 106.8 N at 0.5 MPa. The exact drop-in replacement is the MSBL20X15U, matching the bore, stroke, G1/8 port, and U flat-end back cover.
This SKU lacks the -S magnet option and cannot accept a position sensor. As an upgrade path, the MSBL replacement features a riveted rolling-packed body instead of the older MSAL threaded covers. End-of-stroke deceleration relies on a fixed rubber bumper, as single-acting mini cylinders do not use adjustable cushions. Apply no external load on the spring return stroke to prevent bending the 8mm rod.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X15U Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL20X15U |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15U |
| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15U 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 MSAL20X15U Is Used
PCB Ejector Pin
Pushes populated printed circuit boards out of a test fixture with 106.8 N at 0.5 MPa, letting the spring safely retract the 8mm rod clear of the conveyor.
Sticker Applicator
Extends 15mm to press a label onto small pharmaceutical cartons, relying on the fail-safe retracted home if air pressure drops during a cycle.
Indexer Gate
Acts as a compact diverter for small plastic fasteners on a vibratory bowl feeder, using the U flat-end cover for rigid rear mounting against vibration.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X15U with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15U
To replace this MSAL20X15U, migrate to the MSBL20X15U and verify your 3/2 valve plumbing, as only the push side is pressurized. Ensure your air supply beats the 0.2 MPa minimum working pressure required to overcome the return spring. Because this is the smallest available bore, stepping up means moving to the 25mm bore, which provides 176.4 N of push force at 0.5 MPa. If your application requires position detection, you must select an -S variant of the MSBL to use the newer CMSG, DMSG, or EMSG sensor families, as this no-magnet MSAL cannot take a sensor.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15U (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15U instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X15U FAQ
Yes, the MSAL20X15U is discontinued. The exact drop-in replacement is the AirTAC MSBL20X15U. It matches the 20mm bore, 15mm stroke, G1/8 port, and U flat-end back cover, but upgrades the body to a riveted rolling-packed design.
This single-acting push cylinder delivers a usable force of 106.8 N at 0.5 MPa and 169.6 N at 0.7 MPa, equating to a maximum of about 17.3 kgf. It requires a minimum operating pressure of 0.2 MPa to overcome the internal return spring.
