This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15SU 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 MSAL20X15SU
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X15SU 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15SU.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X15SU
The AirTAC MSAL20X15SU is a discontinued single-acting push cylinder with a 20mm bore and 15mm stroke. Air extends the rod to do its work, while an internal spring retracts it to a fail-safe home when air is removed. The exact drop-in replacement is the MSBL20X15SU, matching the bore, stroke, and G1/8 port. This 20mm bore generates a usable push force of 106.8 N at 0.5 MPa (169.6 N at 0.7 MPa), already net of the opposing spring.
This U-coded SKU features a flat-end back cover for rigid mounting. It includes the -S magnet for position sensing, though the older MSAL uses CS1-M or DS1-M switches while the MSBL replacement 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 type.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X15SU 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15SU 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 MSAL20X15SU Is Used
PCB Ejector Pin
Pushes small printed circuit boards out of a testing fixture using 106.8 N at 0.5 MPa, relying on the spring to retract the 8mm rod safely when air is cut.
Sensor Gate Divertor
Briefly extends 15mm to deflect electronic chips on a conveyor, using the flat U back cover for rigid mounting against the frame.
Light Parts Ejector
Ejects small plastic caps from a moulding station, where the fail-safe spring return guarantees the rod clears the tooling during an air loss event.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X15SU with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15SU
To replace this MSAL20X15SU, install the MSBL20X15SU. Confirm the 20mm bore, 15mm stroke, G1/8 PT port, M8x1.25 rod thread, and the U flat-end back cover. If you use the -S magnet, note that you must upgrade from CS1-M/DS1-M switches to the CMSG/DMSG/EMSG family. Remember the 0.2 MPa minimum operating pressure required to overcome the return spring, and never apply an external load on the spring return stroke.
When sizing, the 20mm bore is the smallest available. If you need more force, stepping up to the 25mm bore yields 176.4 N of push at 0.5 MPa. Because this 15mm stroke is very short, side-load and rod-bending risks are minimal, but you should still ensure precise alignment to protect the 8mm rod.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15SU (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15SU instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X15SU FAQ
Yes, the MSAL20X15SU is discontinued. The exact drop-in replacement is the MSBL20X15SU, which matches the 20mm bore, 15mm stroke, G1/8 port, and U back cover. You will need to upgrade your sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG if you use the magnet.
This single-acting push cylinder provides a usable force of 106.8 N at 0.5 MPa and 169.6 N at 0.7 MPa. It requires a minimum operating pressure of 0.2 MPa to overcome the internal return spring. There is no powered mid-stroke hold; on air loss, the spring drives it to a retracted rest, not a lock.
