This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25SU 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 MSAL20X25SU
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X25SU is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø20mm bore and 25mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25SU.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X25SU
The AirTAC MSAL20X25SU is a discontinued single-acting push mini cylinder with a 20mm bore and 25mm stroke. Air extends the rod to deliver 106.8 N of usable push force at 0.5 MPa, while an internal spring retracts it for a fail-safe home on air loss. The exact drop-in replacement is the MSBL20X25SU, matching the bore, stroke, and G1/8 port.
This U-type flat-end configuration features a -S magnet for CS1-M or DS1-M switches. The MSAL uses threaded covers, whereas the MSBL upgrade features a riveted rolling-packed body. End-of-stroke stopping relies on a fixed rubber bumper, not an adjustable cushion, and the minimum operating pressure is 0.2 MPa to overcome the return spring.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X25SU Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL20X25SU |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25SU |
| Bore size | Ø20 mm |
| Stroke | 25 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25SU 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 MSAL20X25SU Is Used
PCB Ejector Pins
Pushes populated circuit boards out of a test fixture with 106.8 N at 0.5 MPa, relying on the spring return to retract the pin safely when air is cut.
Light-Duty Stamping Press
Applies a short 25mm downward stamping motion on thin foils; the fixed rubber bumper absorbs the end-of-stroke impact without requiring adjustment.
Sensor Gate Diverters
Extends to route small electronic components on a conveyor, using the CS1-M switch to confirm the gate position before parts arrive.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X25SU with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25SU
To replace an MSAL20X25SU, order the MSBL20X25SU and confirm your 20mm bore, 25mm stroke, G1/8 port, PT thread, U flat-end cover, and -S magnet. Note that the MSBL -S magnet uses the newer CMSG, DMSG, or EMSG switches rather than the older CS1-M or DS1-M. Minimum working pressure is 0.2 MPa, and you must apply no external load on the spring return stroke.
If you need less force, step down is not possible as 20mm is the smallest bore. If you need more force, step up to the 25mm bore, which provides 176.4 N of push at 0.5 MPa. For this 25mm stroke on a small bore, side-load and rod-bending risks are minimal, but ensure correct alignment to preserve the front-cover guide.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25SU (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25SU instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X25SU FAQ
Yes, the MSAL20X25SU is discontinued. The exact drop-in replacement is the MSBL20X25SU, which matches the 20mm bore, 25mm stroke, U-type flat cover, and G1/8 port. The MSBL upgrade uses a riveted rolling-packed body and requires CMSG, DMSG, or EMSG switches for the magnet.
This single-acting push cylinder delivers 106.8 N of usable force at 0.5 MPa and 169.6 N at 0.7 MPa. The operating pressure range is 0.2-1.0 MPa, with a minimum of 0.2 MPa required to overcome the internal return spring. The maximum force is approximately 17.3 kgf.
