This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X50CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X50CM 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 MSAL20X50CM
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X50CM is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø20mm bore and 50mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X50CM.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X50CM
The AirTAC MSAL20X50CM is a discontinued single-acting push, spring-return mini cylinder. Air extends the 8mm 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 of usable push force at 0.5 MPa. The exact drop-in replacement is the MSBL20X50CM, matching the bore, stroke, CM round-end cover, and G1/8 port.
Because this SKU lacks the -S magnet, it cannot accept a position sensor. As an upgrade fact, the MSAL uses older CS1-M / DS1-M switches, while the MSBL uses CMSG / DMSG / EMSG. The MSAL also features threaded covers, whereas the MSBL replacement uses a riveted rolling-packed body. This unit uses a fixed rubber bumper for impact absorption, not an adjustable cushion.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X50CM Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL20X50CM |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X50CM |
| Bore size | Ø20 mm |
| Stroke | 50 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X50CM 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 MSAL20X50CM Is Used
PCB Ejector Pins
Pushes unpopulated printed circuit boards out of a routing fixture with 106.8 N at 0.5 MPa, relying on the spring return to clear the area for the next panel.
Lightweight Parts Sorter
Ejects small plastic injection-molded caps from a conveyor guide chute; the fail-safe home guarantees the ejector arm stays clear when air drops.
Battery Cell Deflector
Acts as a mechanical gate to divert 18650 lithium-ion cells into a packing tube, using the fixed rubber bumper to soften end-of-stroke impact.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X50CM with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X50CM
To replace this MSAL20X50CM with the MSBL20X50CM, confirm the 20mm bore, 50mm stroke, G1/8 port, PT thread, and CM round-end cover. Note the sensor family change if you ever add a magnet. A minimum 0.2 MPa operating pressure is required to beat the return spring. Never apply an external load on the spring return stroke.
For sizing, stepping down to the smaller 20mm bore is not an option, but stepping up to the 25mm bore yields 176.4 N at 0.5 MPa. At 50mm stroke on this small body, ensure side loads are minimized to prevent rod bending.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X50CM (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X50CM instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X50CM FAQ
Yes, the MSAL20X50CM is discontinued. The exact drop-in replacement is the MSBL20X50CM, which matches the 20mm bore, 50mm stroke, CM round-end cover, and G1/8 port. 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 (max 17.3 kgf). It requires a minimum operating pressure of 0.2 MPa to overcome the internal return spring and extend the rod.
