This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X75SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X75SU 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 MSAL20X75SU
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X75SU is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø20mm bore and 75mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X75SU.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X75SU
The AirTAC MSAL20X75SU is a discontinued single-acting push, spring-return mini cylinder. Air extends the 8mm rod for a 75mm stroke, while an internal spring retracts it to a fail-safe home when air is removed. The 20mm bore delivers 106.8 N of usable push force at 0.5 MPa. The exact drop-in replacement is the MSBL20X75SU, matching the bore, stroke, and G1/8 port.
This SKU includes a -S magnet for position sensing. The older MSAL uses threaded covers and works with CS1-M / DS1-M reed switches; the MSBL upgrade features a riveted rolling-packed body and uses CMSG / DMSG / EMSG sensors. It has a U flat-end back cover and a fixed rubber bumper. Never apply an external load on the unpowered spring return stroke.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X75SU Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL20X75SU |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X75SU |
| Bore size | Ø20 mm |
| Stroke | 75 mm |
| Acting type | Single acting, push (spring return) |
| Port size | G1/8 |
| Rod thread | M8×1.25 |
| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X75SU carries the same single-acting ratings.
Usable Push Force (Ø20mm)
| Pressure | Push force (net of spring) |
|---|---|
| 0.5 MPa | 106.8 N |
| 0.7 MPa | 169.6 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 MSAL20X75SU Is Used
PCB Ejector Pin
Pushes finished printed circuit boards out of an inspection fixture using 106.8 N at 0.5 MPa, relying on the spring return to clear the lane for the next panel.
Connector Sorter Gate
Diverts plastic connector housings down a reject chute; the spring-return fail-safe home guarantees the gate locks closed on air loss to prevent bad parts passing.
Light Stamp Press
Depresses a date code stamp into cardboard carton flaps, where the fixed rubber bumper absorbs the 75mm stroke impact without needing adjustment.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X75SU with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X75SU
To replace this MSAL20X75SU, install the MSBL20X75SU. Confirm the 20mm bore, 75mm stroke, G1/8 PT port, M8x1.25 rod thread, U back cover, and magnet. Note the sensor family change from CS1-M / DS1-M to CMSG / DMSG / EMSG. Air pressure must be at least 0.2 MPa to overcome the return spring.
If sizing up or down: the 25mm bore neighbor provides 176.4 N at 0.5 MPa, while 20mm is the smallest available bore. For a 75mm stroke on this compact body, mind potential side-load and rod-bending forces during ejection.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X75SU (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X75SU instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X75SU FAQ
Yes, the MSAL20X75SU is discontinued. The exact drop-in replacement is the MSBL20X75SU, which matches the 20mm bore, 75mm stroke, G1/8 port, and single-acting push function. You will only need to update your sensors from CS1-M / DS1-M to the CMSG / DMSG / EMSG family.
This single-acting push cylinder requires a minimum operating pressure of 0.2 MPa to beat the return spring. It delivers a usable push force of 106.8 N at 0.5 MPa and 169.6 N at 0.7 MPa. There is no powered pull force, and the fixed rubber bumper cannot be adjusted.
