This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X40CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X40CM 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 MSAL40X40CM
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X40CM is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø40mm bore and 40mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X40CM.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X40CM
The AirTAC MSAL40X40CM is a discontinued single-acting push cylinder with a 40mm bore and 40mm stroke. Air extends the rod to perform work, while an internal spring retracts it to a fail-safe home when air is removed. 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 MSBL40X40CM, matching the bore, stroke, G1/4 port, and CM mounting.
This SKU has no -S magnet and cannot accept a position sensor. As an MSAL, it uses threaded covers and a fixed rubber bumper, whereas the MSBL upgrade features a riveted rolling-packed body. Minimum working pressure is 0.2 MPa to overcome the return spring, and you must apply no external load on the unpowered return stroke.

| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X40CM 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 MSAL40X40CM Is Used
Stamping Press Ejection
Ejects small stamped metal parts from a die using 539.9 N of push force at 0.5 MPa, relying on the spring return to clear the die before the next cycle.
PCB Router Gating
Actuates a gate on a PCB routing conveyor; the spring return ensures the gate closes safely on air loss, preventing board misalignment.
Spot Welder Clamp
Provides single-direction clamping for a spot welder fixture, applying up to 791.1 N at 0.7 MPa to hold the workpiece before the weld current fires.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X40CM with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X40CM
To replace this MSAL40X40CM, specify the MSBL40X40CM to retain the 40mm bore, 40mm stroke, G1/4 port, PT thread, and CM round-end back cover. Because this SKU lacks the -S magnet, it uses no sensor; if you need position detection on the replacement, add the S option to the MSBL, which uses CMSG/DMSG/EMSG switches rather than the legacy CS1-M/DS1-M. Operating pressure must stay at 0.2-1.0 MPa.
For sizing flexibility, stepping down to the 32mm bore yields 317.7 N at 0.5 MPa, while stepping up is not possible as 40mm is the largest in this series. At 40mm stroke on this compact body, avoid side-loads that could bend the 16mm rod. Remember the fixed rubber bumper cannot be adjusted, and the spring return is a rest, not a lock, so use an external device to hold a load mid-stroke.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X40CM (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X40CM instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X40CM FAQ
Yes, the MSAL40X40CM is discontinued. The exact drop-in replacement is the MSBL40X40CM, which matches the 40mm bore, 40mm stroke, 539.9 N push force at 0.5 MPa, G1/4 port, and CM mounting. The MSBL upgrades the body to a riveted rolling-packed design instead of threaded covers.
The usable push force is 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa. The maximum push force is 791.1 N at 0.7 MPa. The minimum operating pressure is 0.2 MPa because the air must overcome the internal return spring to extend the rod.
