This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL25X40CM, 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 MSAL25X40CM
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL25X40CM is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø25mm bore and 40mm stroke, G1/8 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X40CM.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X40CM
The AirTAC MSAL25X40CM is a discontinued single-acting push cylinder with a 25 mm bore and 40 mm 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 a usable push force of 176.4 N at 0.5 MPa. The direct replacement is the MSBL25X40CM, matching the bore, stroke, G1/8 port, and CM mounting.
This CM configuration features a round-end back cover. Because this specific SKU lacks the -S magnet option, it cannot accept a position sensor. As an upgrade fact, the legacy MSAL uses threaded covers and the older CS1-M / DS1-M switches, whereas the current MSBL features a riveted rolling-packed body and uses CMSG / DMSG / EMSG sensors. End-of-stroke damping relies on a fixed rubber bumper, as single-acting mini cylinders do not use adjustable cushions.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X40CM Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL25X40CM |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X40CM |
| Bore size | Ø25 mm |
| Stroke | 40 mm |
| Acting type | Single acting, push (spring return) |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X40CM carries the same single-acting ratings.
Usable Push Force (Ø25mm)
| Pressure | Push force (net of spring) |
|---|---|
| 0.5 MPa | 176.4 N |
| 0.7 MPa | 274.5 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 MSAL25X40CM Is Used
PCB Ejector Pin
Pushes populated printed circuit boards out of an SMT testing fixture with 176.4 N at 0.5 MPa, relying on the spring return to clear the bay during downtime.
Bottle Flap Diverter
Extends 40 mm to actuate a routing gate on a packaging conveyor, safely defaulting to the retracted home position if the 0.2 MPa air supply drops.
Light Stamp Press
Delivers a single-acting push to emboss date codes on cardboard cartons, absorbing end-of-stroke impact via the fixed rubber bumper.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X40CM with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X40CM
To replace this MSAL25X40CM, specify the MSBL25X40CM to retain the 25 mm bore, 40 mm stroke, PT G1/8 port, M10x1.25 rod-end thread, and CM round-end back cover. Confirm your 3/2 valve supplies at least the 0.2 MPa minimum pressure required to overcome the return spring. Remember that the return stroke is spring-driven; apply no external load on the retraction. At 40 mm of travel on this small bore, rod side-loading should be minimized to prevent guide wear.
If sizing a new application, step down to the 20 mm bore for lighter tasks (106.8 N push at 0.5 MPa) or step up to the 32 mm bore if you need substantially more force (317.7 N push at 0.5 MPa).
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X40CM (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X40CM instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X40CM FAQ
Yes, the MSAL25X40CM is discontinued. The direct replacement is the AirTAC MSBL25X40CM. It matches the 25 mm bore, 40 mm stroke, CM round-end cover, and G1/8 port. The MSBL upgrades the body to a riveted rolling-packed design but maintains the same force class.
The usable push force is 176.4 N at 0.5 MPa and 274.5 N at 0.7 MPa (maximum 28 kgf). The operating pressure range is 0.2-1.0 MPa. A minimum of 0.2 MPa is required because the air pressure must overcome the internal return spring before the rod can extend.
