This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL25X40SU, 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).

The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL25X40SU is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø25mm 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 direct replacement is the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X40SU.
The AirTAC MSAL25X40SU is a discontinued single-acting push mini cylinder with spring return. Air extends the 10mm rod for work strokes; an internal spring retracts it, providing a fail-safe retracted home on air loss. It delivers 176.4 N of usable push force at 0.5 MPa. The direct replacement is the MSBL25X40SU, matching the 25mm bore, 40mm stroke, G1/8 port, and U flat-end back cover.
This SKU includes the -S magnet for position sensing. On the MSAL, the magnet pairs with older CS1-M or DS1-M reed switches; upgrading to the MSBL25X40SU moves you to the newer CMSG, DMSG, or EMSG sensor families. The MSAL features threaded covers, while the MSBL uses a riveted rolling-packed body. Both share a fixed rubber bumper for end-of-stroke damping, lacking adjustable cushioning.

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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL25X40SU carries the same single-acting ratings.
| Pressure | Push force (net of spring) |
|---|---|
| 0.5 MPa | 176.4 N |
| 0.7 MPa | 274.5 N |
Usable single-acting force after the return spring — lower than a same-bore double-acting cylinder. Size with a margin.

Replacement: MSAL → MSBL. Related: MTAL/MTBL (single-acting pull), MAL/MBL (double acting).
Deploys 176.4 N at 0.5 MPa to push cut daughterboards out of a routing fixture, with the spring safely retracting the pin before the spindle returns.
Acts as a spring-return gate on a packaging conveyor, extending to deflect glass vials into a labeling lane and failing safe to home if pneumatic pressure drops.
Pushes a small steel blank out of a progressive die cavity using 274.5 N at 0.7 MPa, relying on the fixed rubber bumper to absorb the unloading impact.
To replace the MSAL25X40SU, order the MSBL25X40SU. Confirm your 25mm bore, 40mm stroke, G1/8 PT thread, U flat-end rear cover, and -S magnet. Remember the sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG. Minimum operating pressure is 0.2 MPa to overcome the return spring. Never apply external load on the spring return stroke.
If sizing a new build, step down to the 20mm bore for lighter tasks (106.8 N push at 0.5 MPa) or step up to the 32mm bore for heavier ejection (317.7 N at 0.5 MPa). At 40mm stroke on these small bores, rod side-load risks bending; ensure rigid front mounting.
Upgrade checklist
Yes, the MSAL25X40SU is discontinued. The direct replacement is the MSBL25X40SU, which matches the 25mm bore, 40mm stroke, G1/8 port, U back cover, and magnet. You will only need to update your sensors from the older CS1-M/DS1-M to the newer CMSG/DMSG/EMSG switches.
This single-acting push cylinder provides 176.4 N of usable force at 0.5 MPa and 274.5 N at 0.7 MPa. It operates from 0.2 to 1.0 MPa, with 0.2 MPa being the minimum required to overcome the internal return spring. It cannot hold a load mid-stroke without external mechanical locking.
