This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL40X75SCA, 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 MSAL40X75SCA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X75SCA 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X75SCA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X75SCA
The AirTAC MSAL40X75SCA is a discontinued single-acting push, spring-return mini cylinder. Air extends the rod for the work stroke, while an internal spring retracts it, providing a fail-safe retracted home on air loss. 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 MSBL40X75SCA, matching the 40 mm bore, 75 mm stroke, G1/4 port, and CA pivot back cover.
This SKU includes the -S magnet for position sensing with older CS1-M or DS1-M reed switches; the MSBL replacement upgrades to CMSG, DMSG, or 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. The CA back cover acts as a pivot clevis, swinging on a pin to accommodate arcing or lateral rod movements during the stroke.

| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X75SCA 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 MSAL40X75SCA Is Used
Stamping Press Ejection
Ejects small stamped metal parts from a die using 539.9 N at 0.5 MPa, with the spring return safely pulling the ejector pin back when air is cut.
Packaging Flap Folding
Pushes cardboard carton flaps closed on a packaging line; the CA pivot absorbs slight misalignment, and the fail-safe retracted home prevents jamming on restart.
Woodworking Clamp
Holds a wooden workpiece against a router fence during cutting. Air applies the clamping force, and the spring releases the part instantly to retracted home.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X75SCA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X75SCA
To replace this MSAL40X75SCA, install the direct replacement MSBL40X75SCA. Confirm the 40 mm bore, 75 mm stroke, G1/4 port, PT thread form, CA pivot back cover, and -S magnet are retained. Note the sensor family change from CS1-M/DS1-M to CMSG/DMSG/EMSG. Maintain a minimum 0.2 MPa operating pressure to overcome the return spring, and apply no external load on the return stroke.
For sizing, this 40 mm bore yields 539.9 N at 0.5 MPa. Stepping down to the 32 mm bore drops the 0.5 MPa push force to 317.7 N, while stepping up is unavailable as 40 mm is the largest MSAL size. The 75 mm stroke on this small body is moderate, but always verify rod alignment to prevent side-load bending.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X75SCA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X75SCA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X75SCA FAQ
Yes, the MSAL40X75SCA is discontinued. The direct replacement is the MSBL40X75SCA, which matches the 40 mm bore, 75 mm stroke, G1/4 port, CA pivot back cover, and force class. You only need to upgrade your position sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG.
The usable push force, already net of the return spring, is 163.1 N at 0.2 MPa, 288.7 N at 0.3 MPa, 414.3 N at 0.4 MPa, 539.9 N at 0.5 MPa, 665.5 N at 0.6 MPa, and 791.1 N at 0.7 MPa (max kgf ~80.6). The operating pressure range is 0.2-1.0 MPa, requiring a minimum of 0.2 MPa to overcome the internal return spring.
