This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X125U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X125U 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 MSAL40X125U
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X125U is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø40mm bore and 125mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X125U.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X125U
The AirTAC MSAL40X125U is a discontinued single-acting push cylinder with a 40mm bore and 125mm stroke. Air extends the rod to do work, while an internal spring retracts it to a fail-safe home when air is removed. It delivers 539.9 N of usable push force at 0.5 MPa and 791.1 N at 0.7 MPa. The exact drop-in replacement is the MSBL40X125U, matching the bore, stroke, G1/4 port, and U back cover.
This U-coded SKU features a flat-end back cover for rigid rear mounting and lacks a magnet, so it cannot accept a position sensor. Upgrading to the MSBL replaces the older threaded covers with a riveted rolling-packed body. End-of-stroke deceleration relies on a fixed rubber bumper, as no adjustable cushion exists in this single-acting series.

| Stroke | 125 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X125U 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 MSAL40X125U Is Used
Sheet Metal Stamping Ejector
Pushes formed aluminum panels out of a stamping die using 539.9 N at 0.5 MPa, with the spring return ensuring parts release safely on air loss.
Injection Mold Gate Cutter
Drives a 125mm stroke to sever plastic runner gates, relying on the fixed rubber bumper to absorb the 50-800 mm/s impact without adjustable cushioning.
Woodworking Conveyor Diverter
Extends to route pine boards down a sorting lane, using the rigid U flat-end back cover to bolt directly to the machine frame.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X125U with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X125U
To replace this MSAL40X125U with the MSBL40X125U, confirm the 40mm bore, 125mm stroke, G1/4 port, PT thread, and U flat-end back cover. Because this SKU has no -S magnet, it cannot hold a sensor; if you need position detection, step up to an MSBL40X125US and use the newer CMSG/DMSG/EMSG switches instead of the legacy CS1-M/DS1-M. Remember the 0.2 MPa minimum pressure required to overcome the return spring, and never apply an external load on the spring return stroke.
If sizing power, stepping down to a 32mm bore yields 317.7 N at 0.5 MPa, while this 40mm provides 539.9 N. Since 40mm is the largest bore in this family, there is no step up; for higher force, use a double-acting MAL cylinder. At 125mm stroke on this compact body, minimize side loads to prevent rod bending and guide binding.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X125U (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X125U instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X125U FAQ
Yes, the MSAL40X125U is discontinued. The exact drop-in replacement is the MSBL40X125U, which matches the 40mm bore, 125mm stroke, G1/4 port, and U back cover. The MSBL upgrades the body to a riveted rolling-packed design but retains the same force class.
The usable push force is 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa (max 80.7 kgf). The minimum operating pressure is 0.2 MPa because the air must overcome the internal return spring to extend the rod.
