This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30U 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 MSAL40X30U
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X30U is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø40mm bore and 30mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30U.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X30U
The AirTAC MSAL40X30U is a discontinued single-acting push, spring-return mini cylinder. Air extends the 30mm stroke while an internal spring retracts the rod to a fail-safe home on air loss. This 40mm bore delivers a usable push force of 539.9 N at 0.5 MPa (791.1 N at 0.7 MPa), already net of the return spring. The exact drop-in replacement is the MSBL40X30U, matching the G1/4 port, M12x1.25 rod thread, and U flat-end back cover.
This non-magnet SKU cannot take a position sensor. Upgrading to the MSBL40X30U swaps the older threaded covers for a riveted rolling-packed body, but if you ever need sensors, the MSBL uses CMSG/DMSG/EMSG switches instead of the legacy CS1-M/DS1-M family. A fixed rubber bumper absorbs end-of-stroke impact, and the minimum operating pressure is 0.2 MPa to overcome the spring.

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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30U 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 MSAL40X30U Is Used
PCB Router Ejection
Deploys 539.9 N at 0.5 MPa to push freshly routed circuit boards out of a machining fixture, relying on the spring return to clear the workspace during tool changes.
Beverage Tray Flap Tucking
Extends 30mm to fold cardboard flaps on a packaging line, where the fail-safe retracted home prevents jams during an emergency air-loss stop.
Connector Press Fit
Applies up to 791.1 N at 0.7 MPa to seat electronic harness connectors into housings, with the fixed rubber bumper absorbing the sudden 30mm end-of-stroke impact.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X30U with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30U
To replace the MSAL40X30U, install the drop-in MSBL40X30U, confirming the 40mm bore, 30mm stroke, G1/4 port, PT thread, and U flat-end back cover. Since this is a non-magnet SKU, it cannot accept a sensor; if your upgrade requires position detection, specify an MSBL40X30US and use CMSG/DMSG/EMSG switches. Maintain at least 0.2 MPa working pressure and apply no external load on the spring return stroke.
If sizing force, stepping down to the 32mm bore drops usable push to 317.7 N at 0.5 MPa, while stepping up is not an option as 40mm is the largest standard MAL mini bore. At 30mm stroke, side-load and rod-bending risks are low, but always ensure rigid front mounting to preserve the U rear cover's alignment.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30U (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30U instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X30U FAQ
