This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X125SCM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X125SCM 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 MSAL20X125SCM
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X125SCM is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø20mm bore and 125mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X125SCM.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X125SCM
The AirTAC MSAL20X125SCM is a discontinued single-acting push, spring-return mini cylinder. Air extends the 8mm rod for the 125mm work stroke; an internal spring retracts it to a fail-safe home when air stops. The exact drop-in replacement is the MSBL20X125SCM, matching the 20mm bore, stroke, G1/8 port, and CM round-end cover. This bore yields 106.8 N usable push at 0.5 MPa (169.6 N at 0.7 MPa), already net of the return spring.
Upgrading to the MSBL swaps the MSAL threaded covers for a riveted rolling-packed body. Your -S magnet currently uses older CS1-M / DS1-M switches; the MSBL requires CMSG / DMSG / EMSG sensors. The MSAL uses a fixed rubber bumper for end-of-stroke damping, not an adjustable cushion. On air loss, the spring drives the rod back to its retracted rest, but it is a defined rest, not a mechanical lock for holding loads.

| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X125SCM 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 MSAL20X125SCM Is Used
PCB Ejector Pins
Pushes finished printed circuit boards out of an SMT testing fixture using 106.8 N at 0.5 MPa. The spring-return fail-safe home guarantees pins retract clear of the conveyor when air drops.
Wafer Cassette Gate
Acts as a spring-loaded stop gate for a 125mm wafer cassette travel. Air extends the 8mm rod to block the cassette; the internal spring safely retracts the gate on air loss.
Light Part Diverter
Diverts small plastic caps on a packaging line. The single-acting push design needs only one 3/2 valve to pressurize the extend side, simplifying pneumatic wiring.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X125SCM with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X125SCM
To replace the MSAL20X125SCM with the MSBL20X125SCM, confirm your 20mm bore, 125mm stroke, G1/8 PT port, M8x1.25 rod-end thread, and CM round-end cover. Swap your CS1-M / DS1-M reed switches to CMSG / DMSG / EMSG units for the new riveted body. Maintain the 0.2 MPa minimum air pressure so the air can beat the return spring, and apply NO external load on the spring return stroke. At 125mm stroke on a 20mm bore, watch for side-load rod-bending on the extended rod. If you need less force, step down to the 15mm bore (if available) or constrain the load; if you need more push, step up to the 25mm bore, which provides 176.4 N at 0.5 MPa.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X125SCM (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X125SCM instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X125SCM FAQ
Yes, the MSAL20X125SCM is discontinued. The exact drop-in replacement is the MSBL20X125SCM. It matches the 20mm bore, 125mm stroke, G1/8 port, CM round-end cover, and single-acting push function. You must update your sensors: the old CS1-M / DS1-M switches are replaced by CMSG / DMSG / EMSG units on the MSBL.
The usable push force is 106.8 N at 0.5 MPa and 169.6 N at 0.7 MPa (max kgf is roughly 17.3 kgf at 0.7 MPa). These figures are net of the return spring. The operating pressure is 0.2-1.0 MPa, with a 0.2 MPa minimum required for air to overcome the spring. The return spring provides a fail-safe retracted home, not a powered mid-stroke hold.
