This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X20SCM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X20SCM 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 MSAL40X20SCM
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X20SCM is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø40mm bore and 20mm stroke, G1/4 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X20SCM.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X20SCM
The AirTAC MSAL40X20SCM is a discontinued 40mm bore, 20mm stroke single-acting push cylinder with a spring return. Air extends the rod for the work stroke, while an internal spring retracts it, providing a fail-safe retracted home on air loss. It delivers 539.9 N of usable push force at 0.5 MPa and 791.1 N at 0.7 MPa. The exact drop-in replacement is the MSBL40X20SCM, matching the bore, stroke, G1/4 port, and CM mounting.
This SKU features a -S magnet for position sensing. The legacy MSAL uses older CS1-M or DS1-M reed switches, whereas the MSBL replacement uses the current CMSG, DMSG, or EMSG families. The MSAL has threaded covers, while the MSBL features a riveted rolling-packed body. Both share a fixed rubber bumper for end-of-stroke damping, as no adjustable cushion exists on this single-acting type.

| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X20SCM carries the same single-acting ratings.
Usable Push Force (Ø40mm)
| Pressure | Push force (net of spring) |
|---|---|
| 0.5 MPa | 539.9 N |
| 0.7 MPa | 791.1 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 MSAL40X20SCM Is Used
Injection Mold Ejection
Provides 539.9 N at 0.5 MPa to eject plastic parts from injection molds, relying on the spring return to safely retract the pin when air is removed.
Pneumatic Staking Press
Delivers 791.1 N at 0.7 MPa for metal staking operations in small assembly lines, where the fixed rubber bumper absorbs the impact at the end of the stroke.
Conveyor Diverter Gate
Pushes a mechanical gate to divert packages on a conveyor, with the fail-safe spring return ensuring the gate opens to a safe home position during an air pressure loss.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X20SCM with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X20SCM
To replace the MSAL40X20SCM, use the drop-in MSBL40X20SCM. Confirm the 40mm bore, 20mm stroke, PT G1/4 port, M12x1.25 rod thread, CM round-end cover, and -S magnet. Remember the sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG. Minimum working pressure is 0.2 MPa to overcome the return spring. Apply no external load on the spring return stroke. Stepping down, the 32mm bore provides 317.7 N at 0.5 MPa; stepping up is not available as 40mm is the largest size. For this 20mm stroke on a 40mm bore, ensure rigid front mounting to prevent rod bending from side loads.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X20SCM (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X20SCM instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X20SCM FAQ
Yes, the MSAL40X20SCM is discontinued. The exact drop-in replacement is the MSBL40X20SCM, which matches the 40mm bore, 20mm stroke, G1/4 port, and CM mounting. The MSBL uses a riveted body instead of threaded covers, and its -S magnet requires CMSG, DMSG, or EMSG switches instead of the older CS1-M/DS1-M.
The usable push force is 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa (equivalent to 80.6 kgf). The minimum operating pressure is 0.2 MPa because the air pressure must overcome the internal return spring to extend the rod.
