This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL20X30SU, 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 MSAL20X30SU
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X30SU is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø20mm bore and 30mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30SU.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X30SU
The AirTAC MSAL20X30SU is a discontinued single-acting push, spring-return mini cylinder. Air extends the rod for the 30mm work stroke, while an internal spring retracts it, providing a fail-safe retracted home on air loss. It delivers a usable push force of 106.8 N at 0.5 MPa. The direct replacement is the MSBL20X30SU, matching the 20mm bore, stroke, G1/8 port, and U back cover.
This SKU includes the -S magnet for position sensing, which uses the older CS1-M or DS1-M switches; the MSBL successor upgrades to CMSG, DMSG, or EMSG sensors. The MSAL features threaded covers and a fixed rubber bumper for end-of-stroke damping, whereas the modern MSBL uses a riveted rolling-packed body. Operating pressure is 0.2-1.0 MPa, requiring at least 0.2 MPa to overcome the return spring.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X30SU Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL20X30SU |

| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30SU |
| Bore size | Ø20 mm |
| Stroke | 30 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30SU 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 MSAL20X30SU Is Used
PCB Ejector Pins
Pushes loose printed circuit boards out of an assembly fixture with 106.8 N at 0.5 MPa, relying on the spring return to safely retract the pin when air is removed.
Chip Test Socket Clamp
Holds a semiconductor test socket closed during electrical probing; the fail-safe retracted home prevents crush damage to the IC if the air supply drops.
Light Packaging Diverter
Acts as a pop-up gate to divert small cartons on a conveyor, using the 30mm stroke and fixed rubber bumper to absorb the stop impact without adjustable cushioning.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X30SU with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30SU
To replace this MSAL20X30SU, install the direct replacement MSBL20X30SU, confirming the 20mm bore, 30mm stroke, PT G1/8 port, U flat-end back cover, and the -S magnet (noting the switch family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG). Maintain the 0.2 MPa minimum air pressure to beat the spring, and apply no external load on the return stroke. If sizing force, stepping down is not an option as 20mm is the smallest bore. Stepping up to the 32mm bore yields 317.7 N at 0.5 MPa, providing a much heavier push if this 106.8 N is insufficient. At 30mm stroke side-load risk is low, but ensure rigid front guide support.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30SU (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30SU instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X30SU FAQ
Yes, the MSAL20X30SU is discontinued. The direct replacement is the MSBL20X30SU, which matches the 20mm bore, 30mm stroke, G1/8 port, U back cover, and single-acting push function. You will only need to update your position sensors, as the MSBL uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M.
The usable push force is 12.6 N at 0.2 MPa, 106.8 N at 0.5 MPa, and 169.6 N at 0.7 MPa (max 17.3 kgf). The operating pressure range is 0.2-1.0 MPa; a minimum of 0.2 MPa is required because the air pressure must overcome the internal return spring to extend the rod.
