This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X50SCM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X50SCM 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 MSAL20X50SCM
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X50SCM 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X50SCM.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X50SCM
The AirTAC MSAL20X50SCM is a discontinued single-acting push mini cylinder with a 20 mm bore, 50 mm stroke, and spring return. Air extends the rod while an internal spring retracts it, providing a fail-safe retracted home on air loss. It delivers a usable push force of 106.8 N at 0.5 MPa. The exact drop-in replacement is the MSBL20X50SCM, matching the bore, stroke, CM round-end back cover, and G1/8 port.
This MSAL20X50SCM SKU includes the -S magnet for position sensing, which uses the older CS1-M or DS1-M switches. Its successor MSBL20X50SCM upgrades to CMSG, DMSG, or EMSG sensors. The original MSAL features threaded covers and a fixed rubber bumper, while the MSBL replacement uses a riveted rolling-packed body. Apply no external load on the spring return stroke.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X50SCM Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL20X50SCM |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X50SCM |
| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X50SCM 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 MSAL20X50SCM Is Used
PCB Ejector Pins
Uses the 106.8 N push force at 0.5 MPa to eject finished printed circuit boards from test fixtures, with the spring ensuring pins retract safely when air is removed.
Light Parts Sorting Gate
Actuates a diverter gate on a small electronics assembly line, where the fail-safe retracted home prevents jamming during an air pressure loss event.
Thin Sheet Metal Clamp
Provides a single-direction hold for stamping 0.5 mm sheet metal, relying on the fixed rubber bumper to absorb impact at the end of the 50 mm stroke.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X50SCM with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X50SCM
To replace the MSAL20X50SCM with the MSBL20X50SCM, confirm the 20 mm bore, 50 mm stroke, M8x1.25 rod-end thread, PT port thread, CM round-end back cover, and -S magnet. Remember the sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG. Maintain a 0.2 MPa minimum working pressure to overcome the return spring.
For sizing, stepping down to the neighbouring bore is not an option as 20 mm is the smallest available. If you need more force, step up to the 25 mm bore, which provides 176.4 N of usable push at 0.5 MPa. For a 50 mm stroke on these small bores, prevent rod bending by ensuring strict alignment and avoiding side loads.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X50SCM (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X50SCM instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X50SCM FAQ
Yes, the MSAL20X50SCM is discontinued. The exact drop-in replacement is the MSBL20X50SCM, which matches the 20 mm bore, 50 mm stroke, G1/8 port, and CM mounting. The MSBL upgrades the body to a riveted rolling-packed design and changes the sensor family from CS1-M/DS1-M to CMSG/DMSG/EMSG.
The usable push force (net of the return spring) is 12.6 N at 0.2 MPa, 44.0 N at 0.3 MPa, 75.4 N at 0.4 MPa, 106.8 N at 0.5 MPa, 138.2 N at 0.6 MPa, and 169.6 N at 0.7 MPa. The maximum equivalent is roughly 17.3 kgf. Operating pressure is 0.2-1.0 MPa, with 0.2 MPa as the minimum to overcome the internal spring.
