This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X20CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X20CA 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 MSAL40X20CA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X20CA is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø40mm bore and 20mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X20CA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X20CA
The AirTAC MSAL40X20CA is a discontinued 40mm bore, 20mm stroke single-acting push cylinder with a spring return. 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. The exact drop-in replacement is the MSBL40X20CA, matching the bore, stroke, port, and force.
This CA version features a pivot clevis back cover that swings on a pin for arcing loads. The original MSAL uses threaded covers and a PT port thread form, whereas the MSBL upgrade features a riveted rolling-packed body. Because this SKU lacks the -S magnet code, it cannot accept a position sensor. The fixed rubber bumper absorbs end-of-stroke impact without adjustment.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X20CA Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL40X20CA |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X20CA |
| Bore size | Ø40 mm |
| Stroke | 20 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X20CA 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 MSAL40X20CA Is Used
Stamping Press Ejection
Ejects small stamped metal parts from a die using 539.9 N of push force at 0.5 MPa, relying on the spring return to safely retract the 16mm rod when air is removed.
Packaging Flap Sealing
Folds carton flaps on a rotary packaging line where the CA pivot clevis accommodates the arcing motion of the moving conveyor without binding.
Woodworking Clamp
Applies single-direction holding pressure on wooden workpieces during routing, using the fail-safe retracted home to release the part instantly if compressed air drops.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X20CA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X20CA
To replace this MSAL40X20CA, specify the MSBL40X20CA to match the 40mm bore, 20mm stroke, G1/4 port, M12x1.25 rod thread, and CA pivot mounting. Remember the 0.2 MPa minimum working pressure needed to overcome the return spring, and apply no external load on the spring return stroke for safety. If sizing down, the 32mm bore neighbor provides 317.7 N at 0.5 MPa; if stepping up, 40mm is the largest available bore in this mini series. At 20mm stroke, side-load rod-bending stress is negligible.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X20CA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X20CA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X20CA FAQ
Yes, the MSAL40X20CA is discontinued. The exact drop-in replacement is the MSBL40X20CA, which matches the 40mm bore, 20mm stroke, CA pivot mount, and G1/4 port. The MSBL upgrade switches to a riveted rolling-packed body, and if you previously used an -S magnet, you must upgrade from the old CS1-M/DS1-M switches to the CMSG/DMSG/EMSG family.
The usable push force (already net of the return spring) is 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa. The maximum push force is roughly 80.7 kgf. The minimum operating pressure is 0.2 MPa because the air supply must overcome the internal return spring to extend the rod.
