This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL25X20SCM, 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 MSAL25X20SCM
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL25X20SCM is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø25mm bore and 20mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X20SCM.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X20SCM
The AirTAC MSAL25X20SCM is a discontinued single-acting push, spring-return mini cylinder. Air extends the 10mm rod for the 20mm work stroke; an internal spring retracts it, providing a fail-safe retracted home on air loss. The bore delivers a usable push force of 176.4 N at 0.5 MPa. The direct replacement is the MSBL25X20SCM, matching the bore, stroke, CM cover, and G1/8 port.
This SKU includes the -S magnet for position sensing. The legacy MSAL uses threaded covers and older CS1-M / DS1-M switches, whereas the MSBL upgrade features a riveted rolling-packed body and CMSG / DMSG / EMSG sensors. It uses a fixed rubber bumper for end-of-stroke damping and requires a minimum 0.2 MPa to overcome the return spring. Never apply an external load on the unpowered return stroke.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X20SCM Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL25X20SCM |

| Bore size | Ø25 mm |
| Stroke | 20 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X20SCM 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 MSAL25X20SCM Is Used
PCB Ejector Pin
Pushes bare circuit boards out of an SMT test fixture using 176.4 N at 0.5 MPa, relying on the spring return to clear the bay before the next panel indexes.
Connector Sorter Gate
Acts as a diverter flap in a vibratory bowl feeder for electronic connectors, using the 20mm stroke to flick parts into the reject lane when air is applied.
Light-Duty Forming Press
Provides a short 20mm stamping action for crimping small sheet metal terminals, safely defaulting to the retracted home position during an E-stop or air loss.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X20SCM with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X20SCM
To replace this MSAL25X20SCM, install the MSBL25X20SCM. Confirm the 25mm bore, 20mm stroke, G1/8 PT port, M10x1.25 rod thread, and CM round-end cover. Swap the CS1-M / DS1-M switches for CMSG / DMSG / EMSG sensors. Maintain at least 0.2 MPa working pressure. If sizing alternatives, stepping down to the 20mm bore drops push force to 106.8 N at 0.5 MPa, while stepping up to the 32mm bore increases it to 317.7 N. For this 20mm stroke, side-load risk is minimal, but always ensure rigid front-cover guide alignment.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X20SCM (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X20SCM instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X20SCM FAQ
Yes, the MSAL25X20SCM is discontinued. The direct replacement is the MSBL25X20SCM, matching the 25mm bore, 20mm stroke, CM cover, and G1/8 port. You must upgrade your sensors: the old MSAL -S magnet uses CS1-M / DS1-M switches, while the new MSBL uses CMSG / DMSG / EMSG switches.
The usable push force is 176.4 N at 0.5 MPa and 274.5 N at 0.7 MPa (maximum 28.0 kgf). Because it is single-acting push with a spring return, the minimum operating pressure is 0.2 MPa to overcome the internal spring. The spring provides a fail-safe retracted home, but it is not a lock for holding mid-stroke loads.
