This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL25X50CM, 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 MSAL25X50CM
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL25X50CM 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X50CM.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X50CM
The AirTAC MSAL25X50CM is a discontinued single-acting push cylinder with spring return. Air extends the 10mm rod for a 50mm work stroke, while an internal spring retracts it to a fail-safe home when air is removed. It yields a usable push force of 176.4 N at 0.5 MPa (274.5 N at 0.7 MPa). The direct replacement is the MSBL25X50CM, matching the 25mm bore, stroke, G1/8 port, and CM round-end cover.
This MSAL25X50CM variant lacks the -S magnet, so it cannot accept a position sensor. The original MSAL uses threaded covers and a PT tapered port thread, whereas the MSBL replacement features a riveted rolling-packed body. End-of-stroke damping relies on a fixed rubber bumper, not an adjustable cushion.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X50CM Technical Specifications

| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X50CM 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 MSAL25X50CM Is Used
PCB Router Ejection
Uses the 176.4 N push force at 0.5 MPa to eject cut printed circuit boards from a router fixture, with the spring returning the arm safely on air loss.
Bottle Sorter Gate
Acts as a diverter gate in a packaging line, extending to redirect plastic bottles and retracting via the internal spring to allow straight pass-through.
Light Stamping Press
Provides a compact 274.5 N stamping thrust at 0.7 MPa for crimping small electrical contacts, relying on the fixed rubber bumper to absorb end-impact.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X50CM with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X50CM
To replace the MSAL25X50CM, order the MSBL25X50CM. Confirm the 25mm bore, 50mm stroke, G1/8 PT port, and CM round-end back cover. Because this SKU lacks the -S magnet, no sensor migration is needed, but if you previously required position detection on a different MSAL variant, the MSBL upgrade switches from CS1-M/DS1-M switches to CMSG/DMSG/EMSG sensors. Remember the 0.2 MPa minimum operating pressure required to overcome the return spring, and apply no external load on the return stroke.
For sizing flexibility, stepping down to the 20mm bore drops the 0.5 MPa push force to 106.8 N, while stepping up to the 32mm bore increases it to 317.7 N. At 50mm stroke, side-load and rod-bending risks are minimal, but always ensure rigid front-trunnion or knuckle mounting to preserve the front-cover guide.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X50CM (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X50CM instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X50CM FAQ
Yes, the MSAL25X50CM is discontinued. The direct replacement is the MSBL25X50CM, which matches the 25mm bore, 50mm stroke, CM round-end cover, G1/8 port, and single-acting push function. The MSBL upgrades the body to a riveted rolling-packed design.
The 25mm bore single-acting push cylinder provides 29.2 N at 0.2 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 because the air pressure must overcome the internal return spring to extend the rod.
