This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL25X50SU, 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 MSAL25X50SU
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL25X50SU is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø25mm bore and 50mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X50SU.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X50SU
The AirTAC MSAL25X50SU is a discontinued single-acting push, spring-return mini cylinder. Air extends the rod for the work stroke, while an internal spring retracts it to a fail-safe home when air is released. This 25mm bore provides a usable push force of 176.4 N at 0.5 MPa (274.5 N at 0.7 MPa), already net of the return spring. The direct replacement is the MSBL25X50SU, matching the 50mm stroke, G1/8 port, and U flat-end back cover.
This SKU includes the -S magnet for position sensing and uses the older CS1-M / DS1-M reed switches. The MSBL upgrade transitions to CMSG / DMSG / EMSG sensors. The MSAL features threaded covers, whereas the MSBL uses a riveted rolling-packed body. A fixed rubber bumper absorbs end-of-stroke impact; there is no adjustable cushion. Apply no external load on the spring return stroke.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X50SU Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL25X50SU |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |

| Bore size | Ø25 mm |
| Stroke | 50 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X50SU 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 MSAL25X50SU Is Used
PCB Ejector Pins
Uses the 176.4 N push force at 0.5 MPa to eject populated printed circuit boards from a test fixture, with the spring ensuring a retracted home during panel loading.
Conveyor Diverter Gate
Pushes a lightweight aluminum diverter arm to route plastic bottles on a packaging line, relying on the fail-safe spring return to open the lane on air loss.
Pneumatic Clamping Arm
Extends a small hold-down clamp to secure a wooden workpiece for a routing operation, using the single-acting push stroke before releasing via the internal spring.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X50SU with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X50SU
To replace the MSAL25X50SU, install the direct replacement MSBL25X50SU. Confirm the 25mm bore, 50mm stroke, G1/8 PT port, M10x1.25 rod-end thread, U flat-end back cover, and -S magnet are retained. Remember the sensor family changes from CS1-M / DS1-M to CMSG / DMSG / EMSG. Minimum operating pressure is 0.2 MPa to overcome the return spring.
If sizing up or down, the neighbouring bore 20mm yields 106.8 N at 0.5 MPa, while the 32mm bore provides 317.7 N at 0.5 MPa. For a 50mm stroke on these small bores, verify rod-bending limits and side-load conditions to prevent premature guide wear.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X50SU (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X50SU instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X50SU FAQ
Yes, the MSAL25X50SU is discontinued. The direct replacement is the MSBL25X50SU, which matches the 25mm bore, 50mm stroke, G1/8 port, U back cover, and -S magnet. You will need to update your sensors, as the MSAL uses CS1-M / DS1-M switches while the MSBL uses CMSG / DMSG / EMSG.
The usable push force, already net of the return spring, is 29.2 N at 0.2 MPa, 127.4 N at 0.4 MPa, 176.4 N at 0.5 MPa, and 274.5 N at 0.7 MPa (max 28 kgf). The minimum operating pressure is 0.2 MPa, as the air pressure must overcome the internal return spring to extend the rod.
