This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X125CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X125CA 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 MSAL40X125CA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X125CA 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X125CA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X125CA
The AirTAC MSAL40X125CA 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 if air is lost. It delivers a usable push force of 539.9 N at 0.5 MPa (791.1 N at 0.7 MPa), already net of the return spring. The exact drop-in replacement is the MSBL40X125CA, matching the 40mm bore, 125mm stroke, G1/4 port, and CA clevis.
This SKU has no -S magnet and cannot accept a position sensor. The MSAL uses threaded covers and older CS1-M/DS1-M switches, whereas the MSBL replacement upgrades to a riveted rolling-packed body and CMSG/DMSG/EMSG sensors. The CA back cover provides a pivot clevis that swings on a pin to accommodate arcing loads. It uses a fixed rubber bumper for end-of-stroke damping. The full force set: push is 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa (max 80.7 kgf); the return spring force is small and not specified.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X125CA Technical Specifications

| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X125CA 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 MSAL40X125CA Is Used
Stamping Press Ejector
Ejects formed sheet metal parts from a die using 539.9 N of push force at 0.5 MPa, with the spring safely retracting the rod clear of the tooling on air loss.
Woodworking Clamp Arm
Applies 791.1 N of holding pressure at 0.7 MPa to secure a workpiece during routing, utilizing the CA clevis to swing freely on a pivot pin as the clamp arm arcs.
Palletizer Diverter Gate
Pushes a cardboard carton onto a secondary conveyor lane; the fail-safe spring return retracts the 125mm stroke gate to home if the compressed air supply drops.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X125CA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X125CA
Replace this MSAL with the MSBL40X125CA: confirm the 40mm bore, 125mm stroke, PT G1/4 port, M12x1.25 rod thread, and CA pivot clevis. Because this SKU lacks the -S magnet, it cannot take a sensor; if you need position detection on the MSBL, add the -S suffix and switch to CMSG/DMSG/EMSG switches. Minimum working pressure is 0.2 MPa to beat the return spring. Apply NO external load on the spring return stroke for safety. At 125mm stroke on this 16mm rod, avoid side-loading to prevent rod bending. To size either direction: stepping down to bore 32 drops the 0.5 MPa push to 317.7 N; stepping up is not possible as 40mm is the largest MSAL bore.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X125CA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X125CA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X125CA FAQ
Yes, the MSAL40X125CA is discontinued. The exact drop-in replacement is the MSBL40X125CA, matching the 40mm bore, 125mm stroke, G1/4 port, and CA clevis. The MSBL upgrades the body to a riveted rolling-packed design.
The usable push force is 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa (max 80.7 kgf), already net of the opposing return spring. The minimum working pressure is 0.2 MPa because the compressed air must overcome the internal spring to extend the rod.
