This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25CM 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 MSAL20X25CM
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X25CM 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25CM.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X25CM
The AirTAC MSAL20X25CM is a discontinued single-acting push, spring-return mini cylinder. Air extends the rod for the work stroke, while an internal spring retracts it to a fail-safe home on air loss. This 20mm bore delivers 106.8 N usable push force at 0.5 MPa. The exact drop-in replacement is the MSBL20X25CM, matching the bore, stroke, G1/8 port, and CM mounting.
This SKU lacks the -S magnet and cannot take a position sensor. As an upgrade fact, the MSAL uses older threaded covers, while the MSBL features a riveted rolling-packed body. It uses a fixed rubber bumper for end-of-stroke damping. Remember that the return spring provides a rest, not a lock; apply no external load on the return stroke.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X25CM Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL20X25CM |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25CM |
| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25CM 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 MSAL20X25CM Is Used
PCB Ejector Pin
Pushes a freshly routed printed circuit board out of a routing fixture with 106.8 N at 0.5 MPa, relying on the spring return to clear the ejector before the next panel loads.
Connector Sorting Gate
Acts as a diverter flap on a vibratory bowl feeder for electronic headers; the fail-safe home ensures the gate opens to reject off-spec parts during an air pressure drop.
Light Duty Spot Weld Clamp
Holds a thin sheet metal bracket against a spot weld electrode; the single-acting push simplifies wiring to one 3/2 valve and the fixed rubber bumper absorbs the stroke impact.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X25CM with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25CM
To replace this MSAL20X25CM with the MSBL20X25CM, confirm the 20mm bore, 25mm stroke, PT G1/8 port, M8x1.25 rod thread, and CM round-end cover. The minimum working pressure is 0.2 MPa to overcome the return spring. If you need less force, there is no smaller standard bore. If you need more force, step up to the 25mm bore, which provides 176.4 N at 0.5 MPa. At this 25mm stroke, side-load is minimal, but always ensure rigid rod mounting to prevent bending.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25CM (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25CM instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X25CM FAQ
Yes, the MSAL20X25CM is discontinued. The exact drop-in replacement is the MSBL20X25CM, which matches the 20mm bore, 25mm stroke, CM cover, and force class. The MSBL upgrades the body to a riveted rolling-packed design but retains the same G1/8 port and PT thread.
The usable push force is 106.8 N at 0.5 MPa and 169.6 N at 0.7 MPa. The operating pressure is 0.2-1.0 MPa, with a 0.2 MPa minimum required to overcome the return spring. The maximum force is 169.6 N (about 17.3 kgf).
