This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL32X20U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL32X20U in place of this model. 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 MSAL32X20U
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL32X20U 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 drop-in replacement is the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL32X20U.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL32X20U
The AirTAC MSAL32X20U is a discontinued 32 mm bore, single-acting push cylinder with a 20 mm stroke. Air extends the rod to provide a usable push force of 317.7 N at 0.5 MPa, while an internal spring retracts it to a fail-safe home when air is removed. The exact drop-in replacement is the MSBL32X20U, matching the bore, stroke, G1/8 port, and U flat-end back cover.
This U-cover SKU has no -S magnet and cannot accept a position sensor. As an upgrade fact, the older MSAL uses threaded covers and the MSBL uses a riveted rolling-packed body. End-of-stroke deceleration relies on a fixed rubber bumper, as there is no adjustable cushion. Minimum operating pressure is 0.2 MPa to overcome the return spring.
Airtac MSAL Front Single Acting Compact Cylinder MSAL32X20U Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL32X20U |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL32X20U |
| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL32X20U 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 MSAL32X20U Is Used
PCB Edge Ejector
Pops finished circuit boards out of a routing fixture using 317.7 N of push force, letting the internal spring safely retract the pin clear of the conveyor.
Stator Lamination Press
Tamps thin steel laminations into a motor housing; the 20 mm stroke delivers a compact hit, and the U flat-end rear mounts flush against the machine frame.
Pneumatic Diverter Gate
Snaps a routing flap into position to sort small plastic parts on a packaging line, with the spring return automatically pulling the gate back on air loss.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL32X20U with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL32X20U
To replace the MSAL32X20U, install the drop-in MSBL32X20U. Confirm the 32 mm bore, 20 mm stroke, PT G1/8 port, M10x1.25 rod-end thread, and rigid U flat-end back cover. Because this SKU lacks the -S magnet, it cannot take a sensor; if you need position feedback, step up to an MSBL32X20SU and use the newer CMSG/DMSG/EMSG switches instead of the legacy CS1-M/DS1-M. Maintain at least 0.2 MPa air pressure to beat the return spring, and apply no external load on the spring return stroke.
For sizing flexibility, stepping down to a 25 mm bore drops the 0.5 MPa push force to 176.4 N, while stepping up to a 40 mm bore increases it to 539.9 N and shifts the port to G1/4. Even at this short 20 mm stroke, prevent rod bending by ensuring strict alignment and avoiding side loads.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL32X20U (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL32X20U instead of this discontinued model.
