This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X40SCM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X40SCM 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).

The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X40SCM is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø20mm bore and 40mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X40SCM.
The AirTAC MSAL20X40SCM is a discontinued single-acting push mini cylinder with a 20mm bore and 40mm stroke. Air extends the rod for the work stroke, while an internal spring retracts it to a fail-safe home when air is removed. The exact drop-in replacement is the MSBL20X40SCM, matching the bore, stroke, G1/8 port, and mounting. This 20mm bore yields a usable push force of 106.8 N at 0.5 MPa and 169.6 N at 0.7 MPa, net of the return spring.
This SKU includes the -S magnet and a CM round-end back cover. The older MSAL uses threaded covers and the -S magnet pairs with CS1-M or DS1-M reed switches. The MSBL20X40SCM upgrade shifts to a riveted rolling-packed body and uses CMSG, DMSG, or EMSG sensors. A fixed rubber bumper absorbs end-of-stroke impact, and the minimum operating pressure is 0.2 MPa to overcome the return spring. Apply no external load on the return stroke.

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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X40SCM carries the same single-acting ratings.

Replacement: MSAL → MSBL. Related: MTAL/MTBL (single-acting pull), MAL/MBL (double acting).
Extends 106.8 N at 0.5 MPa to hold a circuit board edge during pick-and-place assembly, with the spring return safely releasing the panel on air loss.
Pushes a lightweight carton flap closed on a sealing line; the fail-safe retracted home prevents material jams when the line stops.
Applies a 169.6 N peak push at 0.7 MPa to seat an automotive Hall-effect sensor into a housing, using the fixed rubber bumper to prevent impact damage.
To replace this MSAL20X40SCM, install the drop-in MSBL20X40SCM. Confirm the 20mm bore, 40mm stroke, G1/8 PT port, M8x1.25 rod-end thread, and CM round-end back cover. The -S magnet remains, but you must switch from the older CS1-M/DS1-M switches to the MSBL's CMSG/DMSG/EMSG sensor family. Maintain a 0.2 MPa minimum air pressure to beat the return spring, and never apply an external load on the spring return stroke. For sizing flexibility, stepping down is not an option as 20mm is the smallest bore. Stepping up to the 25mm bore gives a higher 176.4 N push at 0.5 MPa if your clamp requires more force. At 40mm stroke on this compact bore, side-load and rod-bending risks are minimal but keep the load axially aligned.
Upgrade checklist
Yes, the MSAL20X40SCM is discontinued. The exact drop-in replacement is the MSBL20X40SCM, which matches the 20mm bore, 40mm stroke, G1/8 port, and CM mounting. You only need to update your sensor selection from the old CS1-M/DS1-M switches to the CMSG/DMSG/EMSG family.
The 20mm bore single-acting push force is 106.8 N at 0.5 MPa and 169.6 N at 0.7 MPa, with a maximum of 17.3 kgf. The operating pressure range is 0.2-1.0 MPa. A 0.2 MPa minimum is required because the air must overcome the internal return spring to extend the rod.
