This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL40X150CM, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 MSAL40X150CM
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X150CM is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø40mm bore and 150mm 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 direct replacement is the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X150CM.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X150CM
The AirTAC MSAL40X150CM is a discontinued single-acting push, spring-return mini cylinder. Air extends the rod for the work stroke, while an internal spring retracts it when air is released, providing a fail-safe retracted home on air loss. At its 40mm bore, it delivers 539.9 N of usable push force at 0.5 MPa (791.1 N at 0.7 MPa). The direct replacement is the MSBL40X150CM, matching the 150mm stroke, G1/4 port, and CM round-end back cover.
This SKU lacks the -S magnet option and therefore cannot accept a position sensor. As an upgrade fact, the original MSAL uses threaded covers and older CS1-M / DS1-M switches, whereas the MSBL replacement features a riveted rolling-packed body and uses CMSG / DMSG / EMSG sensors. End-of-travel deceleration relies on a fixed rubber bumper, not an adjustable cushion.

| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X150CM 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 MSAL40X150CM Is Used
Stamping Press Ejection
Ejects small metal blanks from a die using 539.9 N of push force at 0.5 MPa, with the spring ensuring the retractor clears the press during die changes.
Packaging Flap Folding
Folds heavy cardboard carton flaps on a 150mm stroke, relying on the fail-safe retracted home so the line stays clear if compressed air drops.
Woodworking Gate Diversion
Actuates a diverter gate on a lumber sorting conveyor, using the fixed rubber bumper to absorb the kinetic energy of the 40mm bore at end-of-stroke.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X150CM with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X150CM
To replace this MSAL40X150CM with the MSBL40X150CM, confirm the 40mm bore, 150mm stroke, G1/4 port, PT thread, and CM round-end back cover. Because this SKU has no -S magnet, it cannot take a sensor; if position detection is needed on the MSBL, add the -S code and use CMSG / DMSG / EMSG switches. Operating pressure must be at least 0.2 MPa to beat the return spring, and you must apply no external load on the spring return stroke.
For sizing, step down to the 32mm bore if you need less force (317.7 N at 0.5 MPa), or step up if 539.9 N is insufficient—though 40mm is the largest in this mini family. At 150mm on a 40mm bore, mind the rod-bending risk: keep the load guided to prevent side-load damage.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X150CM (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X150CM instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X150CM FAQ
Yes, the MSAL40X150CM is discontinued. The direct replacement is the MSBL40X150CM, which matches the 40mm bore, 150mm stroke, 539.9 N push force at 0.5 MPa, G1/4 port, and CM mounting.
The usable push force (net of the return spring) is 163.1 N at 0.2 MPa, 414.3 N at 0.4 MPa, 539.9 N at 0.5 MPa, and 791.1 N at 0.7 MPa. The maximum equivalent is roughly 80.6 kgf. Operating pressure is 0.2-1.0 MPa, requiring a minimum of 0.2 MPa to overcome the spring.
