This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X100U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X100U 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 MSAL40X100U
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X100U is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø40mm bore and 100mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X100U.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X100U
The AirTAC MSAL40X100U is a discontinued single-acting push cylinder with a 40mm bore and 100mm 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. The exact drop-in replacement is the MSBL40X100U, sharing the same force class, G1/4 port, and mounting footprint.
This U-cover SKU has no magnet and cannot accept a position sensor. Upgrading to the MSBL brings a riveted rolling-packed body instead of these older threaded covers, and if you ever need sensing, the MSBL uses CMSG/DMSG/EMSG switches rather than the legacy CS1-M/DS1-M family. End-of-stroke energy is absorbed by a fixed rubber bumper, as there is no adjustable cushion.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X100U Technical Specifications

| Bore size | Ø40 mm |
| Stroke | 100 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X100U 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 MSAL40X100U Is Used
Stamping Press Ejection
Ejects formed sheet metal brackets from a stamping die. The 539.9 N push force at 0.5 MPa clears heavy parts, while the spring return safely retracts the rod if air pressure drops.
Injection Mold Gate
Operates a diverter gate on an injection molding line. The 100mm stroke provides ample travel to route plastic runners into the regrind bin, relying on the fixed rubber bumper to absorb the stop impact.
Pallet Flap Lowering
Pushes a hinged flap down to release completed pallets from a packaging conveyor. The flat U back cover mounts rigidly to the machine frame, handling the 791.1 N peak output at 0.7 MPa.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X100U with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X100U
To replace this MSAL40X100U with the MSBL40X100U, verify your 40mm bore, 100mm stroke, G1/4 PT port, M12x1.25 rod thread, and flat U back cover. Because this SKU lacks the -S magnet, you currently have no sensor wiring to migrate, but future sensing on the MSBL requires the newer CMSG/DMSG/EMSG switches. Remember the 0.2 MPa minimum pressure required to overcome the return spring, and apply no external load on the return stroke.
If sizing your push force, stepping down to a 32mm bore drops the 0.5 MPa output to 317.7 N, while 40mm provides 539.9 N. There is no larger standard bore in this mini family, so 40mm is the maximum. At 100mm of stroke on this compact body, ensure your front guide is aligned to prevent rod-bending side loads.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X100U (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X100U instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X100U FAQ
Yes, the MSAL40X100U is discontinued. The exact drop-in replacement is the MSBL40X100U. It matches the 40mm bore, 100mm stroke, 539.9 N push force at 0.5 MPa, G1/4 port, and U back cover. The MSBL upgrades the construction to a riveted rolling-packed body instead of threaded covers.
The usable push force is 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa. The maximum force is roughly 80.7 kgf. Because it is single-acting, the minimum operating pressure is 0.2 MPa to overcome the internal return spring. Note this specific U-cover SKU has no -S magnet and cannot take a sensor.
