This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X50CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X50CM 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 MSAL40X50CM
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X50CM is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø40mm bore and 50mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X50CM.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X50CM
The AirTAC MSAL40X50CM is a discontinued single-acting push cylinder with a 40mm bore and 50mm stroke. Air extends the 16mm rod, while an internal spring retracts it to a fail-safe home. 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 MSBL40X50CM, matching the bore, stroke, G1/4 port, and CM round-end cover.
This MSAL40X50CM features a fixed rubber bumper and PT tapered threads. It lacks the -S option, so it cannot accept a position sensor. When upgrading to the MSBL, note the body changes from threaded covers to a riveted rolling-packed design. Apply no external load on the spring return stroke to prevent rod damage.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X50CM Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL40X50CM |

| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X50CM |
| Bore size | Ø40 mm |
| Stroke | 50 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X50CM 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 MSAL40X50CM Is Used
Stamping Press Ejection
Ejects formed sheet metal parts from a die using 539.9 N at 0.5 MPa. The spring return ensures the ejector retracts safely on air loss.
Woodworking Clamp
Holds cabinetry panels during routing. The 40mm bore provides rigid holding, and the fail-safe home releases the part if air pressure drops.
Packaging Diverter Gate
Pushes cartons onto a secondary conveyor line. The CM round-end cover and 50mm stroke provide quick, compact actuation.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X50CM with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X50CM
Replace this MSAL40X50CM directly with the MSBL40X50CM. Confirm the 40mm bore, 50mm stroke, G1/4 port, PT thread, and CM round-end back cover. Because this SKU lacks the -S magnet, it uses no sensor; if you need position detection in the new line, specify an MSBL with -S to use CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M. Remember the 0.2 MPa minimum pressure required to overcome the return spring.
If sizing a new application, step down to a 32mm bore for 317.7 N at 0.5 MPa, or step up if you need more power. Since this is a 50mm stroke on a small bore, ensure your mounting resists side loads to avoid rod bending. Never apply external load on the return stroke.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X50CM (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X50CM instead of this discontinued model.
