This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X120CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X120CA 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 MSAL40X120CA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X120CA is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø40mm bore and 120mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X120CA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X120CA
The AirTAC MSAL40X120CA is a discontinued single-acting push, spring-return mini cylinder. Air extends the 16 mm rod for the 120 mm stroke, while an internal spring retracts it to a fail-safe home if pressure drops. 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 MSBL40X120CA, matching the 40 mm bore, stroke, CA pivot, and G1/4 port.
This SKU has no -S magnet and cannot accept a position sensor. Upgrading to the MSBL brings a riveted rolling-packed body instead of these threaded covers, and the MSBL sensor family (CMSG/DMSG/EMSG) replaces the older CS1-M/DS1-M switches used on magnetized MSALs. End-of-stroke energy is absorbed by a fixed rubber bumper, not an adjustable cushion.

| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X120CA 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 MSAL40X120CA Is Used
Stamping Press Ejection
Ejects formed sheet metal parts from a die using 539.9 N at 0.5 MPa, with the spring ensuring the arm clears the tool if air fails.
Pivoted Material Diverter
Uses the CA clevis to swing a chute gate on a packaging line, handling arcing motion while pushing 791.1 N at 0.7 MPa to redirect heavy cartons.
Woodworking Clamp Arm
Extends 120 mm to press a fence against lumber on a router table, relying on the fail-safe retracted home to keep the operator safe during jams.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X120CA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X120CA
To replace this MSAL40X120CA with the MSBL40X120CA, verify your CA pivot pin, the G1/4 port, and the M12x1.25 rod-end thread. Because this is a single-acting spring-return unit, air pressure must beat the internal spring, requiring a strict 0.2 MPa minimum. Apply no external load on the return stroke, as the spring is small and only meant to drive the rod home, not hold weight. Stepping down, the 32 mm bore gives 317.7 N at 0.5 MPa; stepping up is not possible as 40 mm is the largest in this mini series. With a 120 mm stroke on this compact body, mind side-load and rod-bending forces to prevent premature seal wear.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X120CA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X120CA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X120CA FAQ
Yes, the MSAL40X120CA is discontinued. The exact drop-in replacement is the MSBL40X120CA, sharing the 40 mm bore, 120 mm stroke, CA pivot, and G1/4 port. The MSBL upgrades the body to a riveted rolling-packed design from the MSAL's threaded covers.
This single-acting push cylinder delivers 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa (max 80.6 kgf). Because an internal spring opposes the air stroke, a 0.2 MPa minimum working pressure is required for the air to overcome the spring and extend the rod.
