This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X15CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X15CM 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 MSAL40X15CM
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X15CM is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø40mm bore and 15mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X15CM.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X15CM
The AirTAC MSAL40X15CM is a discontinued single-acting push cylinder with a 40mm bore and 15mm stroke. Air extends the rod for the work stroke, while an internal spring retracts it to a fail-safe home when air is released. It delivers a usable push force of 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa. The exact drop-in replacement is the MSBL40X15CM, which matches the bore, stroke, G1/4 port, and CM round-end cover.
This SKU lacks the -S magnet option, so it cannot accept a position sensor. As an MSAL series cylinder, it uses threaded covers and the older PT port thread form. The modern MSBL upgrade features a riveted rolling-packed body. Both generations use a fixed rubber bumper for end-of-stroke damping, meaning there is no adjustable cushion. Apply no external load on the spring return stroke, as the spring only provides a small retraction force.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X15CM Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL40X15CM |

| Bore size | Ø40 mm |
| Stroke | 15 mm |
| Acting type | Single acting, push (spring return) |
| Port size | G1/4 |
| Rod thread | M12×1.25 |
| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X15CM 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 MSAL40X15CM Is Used
PCB Router Ejector
Deploys a 15mm pin stroke to push cut printed circuit boards out of a routing fixture, using the 539.9 N force at 0.5 MPa to overcome vacuum adhesion.
Pneumatic Gate Diverter
Extends a 40mm bore plunger to redirect small parts on a packaging conveyor, relying on the spring return to pull the gate back on air loss.
Bearing Press Fit
Applies a brief 15mm push stroke to seat a small bearing into an aluminum housing, using the fixed rubber bumper to absorb the final impact.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X15CM with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X15CM
To replace the MSAL40X15CM, order the MSBL40X15CM. Confirm your 40mm bore, 15mm 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 you need position feedback, the MSBL equivalent requires adding an -S code and switching from the old CS1-M/DS1-M switches to the modern CMSG/DMSG/EMSG family. Remember the 0.2 MPa minimum operating pressure required to overcome the return spring.
For sizing flexibility, the next size down is the 32mm bore, which provides 317.7 N of push force at 0.5 MPa. Stepping up is not possible as 40mm is the largest MSAL bore. Even at a short 15mm stroke, maintain strict rod alignment to prevent side-load wear on the front-cover guide.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X15CM (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X15CM instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X15CM FAQ
Yes, the MSAL40X15CM is discontinued. The exact drop-in replacement is the MSBL40X15CM, which matches the 40mm bore, 15mm stroke, G1/4 port, and CM round-end cover. The MSBL upgrades the body to a riveted rolling-packed design instead of threaded covers, but maintains the same force class.
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 because the air pressure must overcome the internal return spring. The maximum operating pressure is 1.0 MPa.
