This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL25X100SU, 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 MSAL25X100SU
The AirTAC MSAL Front Single Acting Compact Cylinder MSAL25X100SU is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø25mm bore and 100mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X100SU.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X100SU
The AirTAC MSAL25X100SU is a discontinued single-acting push, spring-return mini cylinder. Air extends the rod for the work stroke, while an internal spring retracts it, providing a fail-safe retracted home on air loss. It delivers a usable push force of 176.4 N at 0.5 MPa. The direct replacement is the MSBL25X100SU, matching the 25 mm bore, 100 mm stroke, G1/8 port, and U back cover.
This SKU includes the -S magnet and a U flat-end back cover. As an upgrade fact, this MSAL uses threaded covers and older CS1-M / DS1-M reed switches, whereas the MSBL replacement features a riveted rolling-packed body and modern CMSG / DMSG / EMSG sensors. The fixed rubber bumper absorbs end-of-stroke impact, as there is no adjustable cushion. Note that the return spring provides a rest, not a lock; apply no external load on the return stroke.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X100SU Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL25X100SU |

| Bore size | Ø25 mm |
| Stroke | 100 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X100SU 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 MSAL25X100SU Is Used
PCB Router Ejector
Uses the 176.4 N push force at 0.5 MPa to eject cut circuit boards from a router bed, with the spring ensuring the arm clears the workspace on air loss.
Foil Pouch Flap Press
Closes packaging flaps on a vertical form-fill-seal machine; the fixed rubber bumper handles the 100 mm stroke impact without adjustable cushions.
Bottleneck Divert Gate
Extends a guide rail to sort glass bottles into a secondary labeling lane, relying on the fail-safe retracted home to clear the conveyor during an e-stop.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL25X100SU with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X100SU
To replace this MSAL25X100SU, install the direct replacement MSBL25X100SU. Confirm the 25 mm bore, 100 mm stroke, PT thread, U flat-end back cover, and G1/8 port match your manifold. The -S magnet transfers over, but you must upgrade from CS1-M / DS1-M switches to CMSG / DMSG / EMSG sensors. Maintain a minimum 0.2 MPa operating pressure to overcome the return spring, and never apply an external load on the unpowered return stroke.
For sizing, step down to the 20 mm bore (106.8 N push at 0.5 MPa) for lighter ejects, or step up to the 32 mm bore (317.7 N at 0.5 MPa) for higher press force. Because this 100 mm stroke is long for a 25 mm bore, watch for rod bending and side loads—use a guide rail to prevent premature seal wear.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X100SU (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X100SU instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL25X100SU FAQ
Yes, the MSAL25X100SU is discontinued. The direct replacement is the MSBL25X100SU, which matches the 25 mm bore, 100 mm stroke, G1/8 port, U back cover, and single-acting push function. You only need to swap the CS1-M / DS1-M sensors for CMSG / DMSG / EMSG switches.
The usable push force is 176.4 N at 0.5 MPa and 274.5 N at 0.7 MPa. The minimum operating pressure is 0.2 MPa, which is required to overcome the internal return spring so air can extend the rod.
