This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL25X50SCM, 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 MSAL25X50SCM
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL25X50SCM 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X50SCM.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X50SCM
The AirTAC MSAL25X50SCM is a discontinued single-acting push, spring-return mini cylinder. Air extends the Ø25 mm rod for the 50 mm work stroke; an internal spring drives fail-safe retraction to a defined home when air drops. It yields a usable push force of 176.4 N at 0.5 MPa (274.5 N at 0.7 MPa), already net of the opposing spring. The direct replacement is the MSBL25X50SCM.
This SKU features a -S magnet for position sensing. The legacy MSAL works with older CS1-M / DS1-M reed switches, whereas the MSBL successor upgrades to CMSG / DMSG / EMSG sensors. The MSAL body uses threaded covers, while the MSBL uses a riveted rolling-packed body. End-of-stroke deceleration relies on a fixed rubber bumper, meaning there is no adjustable cushion. A 50 mm stroke on a mini body is safe, but avoid side loads that bend the rod.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X50SCM Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL25X50SCM |

| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X50SCM |
| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X50SCM 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 MSAL25X50SCM Is Used
PCB Router Ejector
Pushes singulated circuit boards out of a routing fixture with 176.4 N at 0.5 MPa; the spring retracts the pin clear of the workspace on air loss.
Bottle Divert Gate
Extends a 50 mm guide flap to deflect containers on a packaging line, then relies on the fail-safe spring return to open the lane when compressed air stops.
Clip Press Insertion
Drives a retaining clip into an aluminum housing during appliance assembly; the fixed rubber bumper absorbs the end impact without external adjustment.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X50SCM with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X50SCM
To replace the MSAL25X50SCM, order the MSBL25X50SCM. Confirm the shared specs: Ø25 bore, 50 mm stroke, G1/8 port, PT thread, CM round-end back cover, and the magnet for sensing (noting the switch family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG). Maintain the 0.2 MPa minimum air pressure to beat the return spring, and apply no external load on the unpowered return stroke.
Size both ways: step down to the Ø20 bore for 106.8 N push at 0.5 MPa, or up to the Ø32 bore for 317.7 N at 0.5 MPa. The Ø25 hits 176.4 N at 0.5 MPa.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X50SCM (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X50SCM instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X50SCM FAQ
Yes, the MSAL25X50SCM is discontinued. The direct replacement is the MSBL25X50SCM, matching the 25 mm bore, 50 mm stroke, G1/8 port, CM cover, and magnet. The MSBL upgrades the sensor family from CS1-M/DS1-M to CMSG/DMSG/EMSG and uses a riveted body instead of threaded covers.
The usable push force is 29.2 N at 0.2 MPa, 78.3 N at 0.3 MPa, 127.4 N at 0.4 MPa, 176.4 N at 0.5 MPa, 225.5 N at 0.6 MPa, and 274.5 N at 0.7 MPa (max 28 kgf). These figures are net of the opposing return spring. You must supply at least 0.2 MPa to overcome the spring and extend the rod.
