This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL40X50SCA, 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 MSAL40X50SCA is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø40mm bore and 50mm stroke, G1/4 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X50SCA.
The AirTAC MSAL40X50SCA is a discontinued single-acting push, spring-return mini cylinder. Air extends the 16mm rod for the 50mm work stroke, while an internal spring retracts it to a fail-safe home when air is removed. It delivers a usable push force of 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa. The direct replacement is the MSBL40X50SCA, matching the 40mm bore, G1/4 port, and CA pivot back cover.
This SKU includes the -S magnet, which works with older CS1-M / DS1-M switches; the MSBL replacement uses CMSG / DMSG / EMSG sensors. The MSAL uses threaded covers, whereas the MSBL features a riveted rolling-packed body. End-of-stroke damping relies on a fixed rubber bumper, not an adjustable cushion. Never apply an external load on the spring return stroke, as the spring only provides a small retraction force.

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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X50SCA carries the same single-acting ratings.
| Pressure | Push force (net of spring) |
|---|---|
| 0.5 MPa | 539.9 N |
| 0.7 MPa | 791.1 N |
Usable single-acting force after the return spring — lower than a same-bore double-acting cylinder. Size with a margin.

|---|---|
| 40 | Bore size in mm (20/25/32/40). |
| ×50 | Stroke length in mm. |
| S | Optional magnet for a CS1-M / DS1-M sensor (MSBL uses CMSG/DMSG/EMSG). |
| CA / U / CM | Back cover: CA pivot, U flat-end or CM round-end. |
Replacement: MSAL → MSBL. Related: MTAL/MTBL (single-acting pull), MAL/MBL (double acting).
Ejects small stamped metal parts from a die using 539.9 N of push force at 0.5 MPa, relying on the spring return to safely retract the 16mm rod when air pressure drops.
Swings a material flow flap on a packaging line using the CA pivot back cover, using the fail-safe spring return to pull the gate closed during an air loss emergency.
Holds a wooden workpiece against a routing table with 791.1 N at 0.7 MPa, releasing instantly when the 3/2 valve vents air, allowing the fixed rubber bumper to absorb the stop impact.
Replace the MSAL40X50SCA with the MSBL40X50SCA. Confirm the 40mm bore, 50mm stroke, PT G1/4 port, M12x1.25 rod thread, and CA pivot back cover. The -S magnet requires changing your CS1-M / DS1-M switches to the CMSG / DMSG / EMSG family. Maintain the 0.2 MPa minimum working pressure so air can overcome the return spring.
For sizing both ways: step down to the 32mm bore for lighter loads (317.7 N push at 0.5 MPa), or step up if you need more force (40mm is the largest MSAL size, offering 791.1 N at 0.7 MPa). With a 50mm stroke on this compact body, keep the load guided to prevent rod-bending side loads.
Upgrade checklist
Yes, the MSAL40X50SCA is discontinued. The direct replacement is the MSBL40X50SCA, matching the 40mm bore, 50mm stroke, CA pivot, and G1/4 port. You must upgrade your CS1-M / DS1-M sensors to the CMSG / DMSG / EMSG family for the new riveted body.
The usable push force (net of the return spring) is 163.1 N at 0.2 MPa, 539.9 N at 0.5 MPa, and 791.1 N at 0.7 MPa. The minimum operating pressure is 0.2 MPa because the incoming air must overcome the internal return spring to extend the rod.
