This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X75U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X75U 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).
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X75U
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X75U 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 drop-in replacement is the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X75U.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X75U
AirTAC MSAL40X75U is a discontinued single-acting push, spring-return mini cylinder. Air extends the rod for the 75mm work stroke, and an internal spring retracts it to a fail-safe home when air drops. This 40mm bore delivers a usable push force of 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa, already net of the opposing return spring.
The exact drop-in replacement is MSBL40X75U, matching the bore, stroke, G1/4 port, and U flat-end back cover. This MSAL has threaded covers and no -S magnet, meaning it cannot take a position sensor. The MSBL upgrade uses a riveted rolling-packed body and, if you need sensing, CMSG/DMSG/EMSG switches. End-of-stroke energy is absorbed by a fixed rubber bumper, not an adjustable cushion.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X75U Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL40X75U |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X75U |
| Bore size | Ø40 mm |
| Stroke | 75 mm |
| Acting type | Single acting, push (spring return) |
| Port size | G1/4 |
| Rod thread | M12×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.2 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X75U 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 MSAL40X75U Is Used
Stamping Press Ejection
Ejects stamped metal blanks from a 40-ton press using 539.9 N of push force at 0.5 MPa, with the spring ensuring the rod retracts clear before the next cycle.
Plastic Injection Mold Core
Acts as a core puller in a plastic injection mold, where the U flat-end cover provides rigid rear mounting and the fail-safe home prevents mold damage on air loss.
Woodworking Line Diverter
Pushes wooden planks onto a secondary conveyor in a woodworking line, using the G1/4 port for high-flow extension and the fixed rubber bumper to absorb the 75mm stroke impact.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X75U with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X75U
To replace MSAL40X75U with MSBL40X75U, confirm the 40mm bore, 75mm stroke, G1/4 port, PT thread, and U flat-end back cover. Because this SKU lacks the -S magnet, it cannot accept a sensor; if sensing is needed, the MSBL replacement requires CMSG/DMSG/EMSG switches. Maintain the 0.2 MPa minimum air pressure to overcome the return spring, and apply no external load on the spring return stroke.
For sizing both ways: step down to the 32mm bore (317.7 N push @0.5 MPa) for lighter ejection duties, or step up if 539.9 N is insufficient. At 75mm stroke on this 40mm bore, mind side-load and rod-bending forces to prevent premature guide wear.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X75U (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X75U instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X75U FAQ
Yes, the MSAL40X75U is discontinued. The exact drop-in replacement is the MSBL40X75U, which matches the 40mm bore, 75mm stroke, 539.9 N push force at 0.5 MPa, G1/4 port, and U flat-end back cover. The MSBL upgrades to a riveted rolling-packed body.
The usable push force is 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa (roughly 80.7 kgf). The minimum operating pressure is 0.2 MPa because the air must overcome the internal return spring to extend the rod.
