This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL32X20SU, 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 MSAL32X20SU
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL32X20SU is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø32mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL32X20SU.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL32X20SU
The AirTAC MSAL32X20SU is a discontinued single-acting push, spring-return mini cylinder. Air extends the 12mm rod to execute work; an internal spring retracts it when air drops, providing a fail-safe retracted home. It delivers a usable push force of 317.7 N at 0.5 MPa. The direct replacement is the MSBL32X20SU, matching the 32mm bore, 20mm stroke, G1/8 port, and U back cover.
This -S variant includes a magnet for position sensing. On the MSAL it uses the older CS1-M or DS1-M switches, whereas the MSBL replacement takes CMSG, DMSG, or EMSG sensors. The legacy MSAL features threaded covers, while the current MSBL uses a riveted rolling-packed body. End-of-stroke deceleration relies on a fixed rubber bumper, as single-acting models lack adjustable cushions.
Airtac MSAL Front Single Acting Compact Cylinder MSAL32X20SU Technical Specifications

| Bore size | Ø32 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL32X20SU carries the same single-acting ratings.
Usable Push Force (Ø32mm)
| Pressure | Push force (net of spring) |
|---|---|
| 0.5 MPa | 317.7 N |
| 0.7 MPa | 478.5 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 MSAL32X20SU Is Used
PCB Router Ejection
Pushes singulated circuit boards out of a routing fixture with 317.7 N at 0.5 MPa; the spring return clears the path for the next panel.
Aluminum Extrusion Stopping
Acts as a hard stop gate for 20mm profile sections on a cut-off saw line, retracting safely on air loss to clear the material feed.
Packaging Flap Folding
Extends to tuck carton flaps during case erecting, using the short 20mm stroke and fail-safe home to prevent jamming if air pressure drops.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL32X20SU with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL32X20SU
To replace this MSAL32X20SU, migrate to the MSBL32X20SU and verify your 32mm bore, 20mm stroke, G1/8 PT port, U flat-end back cover, and mounting hardware. Swap your CS1-M or DS1-M reed switches for CMSG, DMSG, or EMSG sensors. Maintain a minimum 0.2 MPa operating pressure to overcome the return spring, and never apply external loads on the spring return stroke. If sizing alternatives, stepping down to a 25mm bore yields 176.4 N at 0.5 MPa, while stepping up to a 40mm bore provides 539.9 N at 0.5 MPa.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL32X20SU (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL32X20SU instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL32X20SU FAQ
Yes, the MSAL32X20SU is discontinued. The direct replacement is the MSBL32X20SU, which matches the 32mm bore, 20mm stroke, G1/8 port, and U back cover. You will need to upgrade your position sensors from the older CS1-M or DS1-M to the CMSG, DMSG, or EMSG series.
The single-acting push force is net of the return spring. It provides 317.7 N at 0.5 MPa and 478.5 N at 0.7 MPa, with a maximum of roughly 48.8 kgf. The operating pressure range is 0.2-1.0 MPa, and you must maintain at least 0.2 MPa for air to overcome the internal spring.
