This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL40X50CM, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 direct 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 direct 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

| 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.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X50CM FAQ
Yes, the MSAL40X50CM is discontinued. The direct replacement is the MSBL40X50CM, matching the 40mm bore, 50mm stroke, G1/4 port, and CM cover. The MSBL upgrades the body to a riveted rolling-packed design.
It provides 539.9 N usable push force at 0.5 MPa and 791.1 N at 0.7 MPa. The operating pressure range is 0.2-1.0 MPa. A minimum of 0.2 MPa is required to overcome the return spring. It has no -S magnet and cannot take a sensor.
