This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL40X75SU, 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).
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X75SU
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X75SU is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø40mm bore and 75mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X75SU.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X75SU
The AirTAC MSAL40X75SU is a discontinued single-acting push, spring-return mini cylinder. Air extends the rod for the work stroke, while an internal spring retracts it to a fail-safe home when air is released. 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 MSBL40X75SU, sharing the same 40mm bore, 75mm stroke, G1/4 port, and U flat-end back cover.
This SKU includes the -S magnet for position sensing. The legacy MSAL uses older CS1-M or DS1-M reed switches, whereas the modern MSBL replacement takes CMSG, DMSG, or EMSG sensors. The MSAL features threaded covers, while the MSBL upgrades to a riveted rolling-packed body. End-of-stroke damping relies on a fixed rubber bumper, as single-acting models lack adjustable cushions.

| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X75SU carries the same single-acting ratings.
Usable Push Force (Ø40mm)
| 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.

Where the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X75SU Is Used
PCB Router Clamping
Holds a printed circuit board panel flat against a router fixture during depaneling. The 539.9 N push force at 0.5 MPa secures the board, while the spring return clears the clamp for robotic unloading.
Stamping Press Ejector
Ejects small stamped metal parts from a die cavity. Air extends the rod to push the part free, and the spring-return fail-safe home guarantees the ejector retracts clear before the next press cycle.
Conveyor Diverter Gate
Pushes a lightweight pneumatic diverter gate to sort small plastic housings on a packaging line. The G1/4 port provides ample flow, and the fixed rubber bumper absorbs the gate stop impact.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X75SU with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X75SU
To replace this MSAL40X75SU, specify the MSBL40X75SU. Confirm the 40mm bore, 75mm stroke, PT G1/4 port, M12x1.25 rod-end thread, U flat-end back cover, and the -S magnet (noting the sensor family change to CMSG/DMSG/EMSG). Maintain a minimum working pressure of 0.2 MPa to overcome the return spring, and apply no external load on the spring return stroke for safety.
For sizing flexibility, stepping down to the 32mm bore yields 317.7 N push force at 0.5 MPa, while the 40mm bore is the largest in this mini family at 539.9 N. At 75mm stroke on this 40mm body, ensure the rod is guided to prevent side-load bending.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X75SU (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X75SU instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X75SU FAQ
Yes, the MSAL40X75SU is discontinued. The direct replacement is the MSBL40X75SU, which matches the 40mm bore, 75mm stroke, G1/4 port, U flat-end cover, and single-acting push function. You will only need to update your position sensors, as the MSBL uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M.
This single-acting push cylinder provides a usable force of 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa (max 80.7 kgf). It requires a minimum operating pressure of 0.2 MPa to overcome the internal return spring and extend the rod.
