This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X10U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X10U 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 MSAL40X10U
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X10U is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø40mm bore and 10mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X10U.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X10U
The AirTAC MSAL40X10U is a discontinued 40 mm bore, 10 mm 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 home position when air is removed. It delivers a usable push force of 539.9 N at 0.5 MPa (791.1 N at 0.7 MPa), requiring a minimum 0.2 MPa operating pressure to overcome the return spring. The exact drop-in replacement is the MSBL40X10U, matching the bore, stroke, G1/4 port, and force class.
This U-model features a flat-end back cover and a fixed rubber bumper for end-of-stroke damping. Because this specific SKU lacks the -S magnet option, it cannot accept a position sensor. Upgrading to the MSBL40X10U brings a riveted rolling-packed body instead of the older threaded covers, and if sensing is needed, the new line supports CMSG, DMSG, or EMSG switches rather than the legacy CS1-M or DS1-M types.

|---|---|
| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X10U 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 MSAL40X10U Is Used
Punch Press Ejector
Uses the 539.9 N push force at 0.5 MPa to eject stamped metal sheets from a die, relying on the spring return to retract fast for the next cycle.
Packaging Flap Tucker
Extends 10 mm to tuck carton side flaps on a packaging line, with the fail-safe spring return ensuring the arm clears if air pressure drops.
Bottle Divert Gate
Acts as a short-stroke diverter on a conveyor, pushing glass bottles into a secondary lane using the 791.1 N available at 0.7 MPa.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X10U with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X10U
To replace the MSAL40X10U, select the MSBL40X10U and confirm the 40 mm bore, 10 mm stroke, G1/4 port, PT thread, and U flat-end back cover. Since this SKU has no magnet, it cannot hold a sensor; if position detection is needed, move to an MSBL40X10US and use CMSG, DMSG, or EMSG switches. Maintain a minimum 0.2 MPa air pressure to beat the return spring, and never apply an external load on the spring return stroke to avoid damaging the internals.
If sizing force down, the 32 mm bore neighbor provides 317.7 N of push at 0.5 MPa. If stepping up, 40 mm is the largest standard MSAL bore, offering 539.9 N at 0.5 MPa. With a short 10 mm stroke on this 40 mm body, keep the mount rigidly square to prevent side-load rod-bending issues.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X10U (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X10U instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X10U FAQ
Yes, the MSAL40X10U is discontinued. The exact drop-in replacement is the MSBL40X10U, which matches the 40 mm bore, 10 mm stroke, G1/4 port, and U back cover. The MSBL upgrades the body to a riveted rolling-packed design and uses CMSG, DMSG, or EMSG sensors if you add the -S option.
The usable push force is 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa. The minimum operating pressure is 0.2 MPa, which is required to overcome the internal return spring. The cylinder uses a fixed rubber bumper, not an adjustable cushion.
