This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X100SCM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X100SCM 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 MSAL20X100SCM
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X100SCM is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø20mm 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 drop-in replacement is the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X100SCM.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X100SCM
The AirTAC MSAL20X100SCM is a discontinued single-acting push mini cylinder with a 20mm bore and 100mm stroke. Air extends the rod for the work cycle, while an internal spring retracts it to a fail-safe home when air is removed. It delivers 106.8 N of usable push force at 0.5 MPa. The exact drop-in replacement is the MSBL20X100SCM, which matches the bore, stroke, CM round-end cover, and G1/8 port.
This SKU includes the -S magnet for position sensing, which uses the older CS1-M or DS1-M switches; the MSBL replacement upgrades this to CMSG, DMSG, or EMSG sensors. The MSAL features threaded covers, whereas the MSBL uses a riveted rolling-packed body. End-of-stroke deceleration relies on a fixed rubber bumper, as single-acting mini cylinders lack adjustable cushioning.

| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X100SCM 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 MSAL20X100SCM Is Used
PCB Ejector Station
Pushes finished printed circuit boards out of an assembly fixture using 106.8 N at 0.5 MPa, relying on the spring return to retract the 8mm rod safely when air is cut.
Small Parts Sorter Gate
Actuates a diverter flap on a conveyor for plastic injection-molded components, using the 100mm stroke to clear the belt path and the fail-safe home to halt flow during stops.
Light-Duty Press Arm
Applies a brief clamping force on thin sheet metal housings, where the fixed rubber bumper absorbs the end-stroke impact and the spring retracts the arm instantly upon release.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X100SCM with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X100SCM
To replace the MSAL20X100SCM, install the MSBL20X100SCM drop-in, confirming the 20mm bore, 100mm stroke, G1/8 port, PT thread, CM round-end back cover, and the -S magnet sensor family change from CS1-M/DS1-M to CMSG/DMSG/EMSG. Maintain a minimum 0.2 MPa operating pressure for air to overcome the return spring, and apply no external load on the spring return stroke for safety. If you need to step down, the neighbouring smaller bore is unavailable, so reduce pressure to achieve lower force. If you need more force, step up to the 25mm bore, which provides 176.4 N of push at 0.5 MPa. Because this 100mm stroke is long for a 20mm bore, carefully manage side loads to prevent rod-bending and premature seal wear.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X100SCM (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X100SCM instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X100SCM FAQ
Yes, the MSAL20X100SCM is discontinued. The exact drop-in replacement is the MSBL20X100SCM, which matches the 20mm bore, 100mm stroke, CM round-end cover, G1/8 port, and mounting. The MSBL upgrades the body to a riveted rolling-packed design and changes the -S magnet sensor compatibility from CS1-M/DS1-M to CMSG/DMSG/EMSG.
The usable push force is 106.8 N at 0.5 MPa and 169.6 N at 0.7 MPa, yielding a maximum of roughly 17.3 kgf. The minimum operating pressure is 0.2 MPa, which is required for the compressed air to overcome the internal return spring and extend the rod.
