This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X40CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X40CM 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 MSAL20X40CM
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X40CM is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø20mm bore and 40mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X40CM.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X40CM
The AirTAC MSAL20X40CM is a discontinued single-acting push, spring-return mini cylinder. Air extends the 8mm rod for the 40mm stroke, while an internal spring retracts it to a fail-safe home on air loss. It delivers 106.8 N of usable push force at 0.5 MPa and 169.6 N at 0.7 MPa. The exact drop-in replacement is the MSBL20X40CM, matching the 20mm bore, stroke, G1/8 port, and CM round-end cover.
This CM-cover SKU lacks the -S magnet and cannot take a position sensor. As an upgrade fact, the MSAL uses threaded covers and older switches, while the MSBL replacement features a riveted rolling-packed body. The fixed rubber bumper absorbs end-of-stroke impact, but remember the spring return is a rest, not a lock, so apply no external load on the return stroke.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X40CM Technical Specifications

| Bore size | Ø20 mm |
| Stroke | 40 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X40CM 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 MSAL20X40CM Is Used
PCB Ejector Pins
Pushes thin printed circuit boards out of a test fixture with 106.8 N at 0.5 MPa, relying on the spring return to retract the 8mm rod safely when air drops.
Light Stamp Pressing
Applies a 169.6 N stamping force at 0.7 MPa to small paper or foil packaging, with the fixed rubber bumper absorbing the impact at the end of the 40mm stroke.
Sorter Diverter Gate
Extends to block small electronic components on a conveyor line, using the fail-safe retracted home to clear the path during an air loss emergency.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X40CM with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X40CM
To replace the MSAL20X40CM with the MSBL20X40CM, confirm your 20mm bore, 40mm stroke, G1/8 PT port, and CM round-end cover. Because this SKU has no -S magnet, you currently run no sensor; if you need position sensing in the future, the MSBL uses the newer CMSG/DMSG/EMSG switches rather than the older CS1-M/DS1-M family. Keep the 0.2 MPa minimum operating pressure so air can beat the return spring.
For sizing, if you need less force, there is no smaller standard 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. At 40mm stroke on this 20mm bore, side-load and rod-bending risks are low, but always keep the load axial. Never apply an external load on the spring return stroke.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X40CM (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X40CM instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X40CM FAQ
Yes, the MSAL20X40CM is discontinued. The exact drop-in replacement is the MSBL20X40CM, which matches the 20mm bore, 40mm stroke, G1/8 port, and CM round-end cover. The MSBL upgrades the body to a riveted rolling-packed design.
The usable push force is 106.8 N at 0.5 MPa and 169.6 N at 0.7 MPa, yielding roughly 17.3 kgf max. The minimum operating pressure is 0.2 MPa, as the air must overcome the internal return spring to extend the rod.
