This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X120SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X120SCA 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 MSAL40X120SCA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X120SCA 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X120SCA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X120SCA
The AirTAC MSAL40X120SCA is a discontinued 40mm bore, single-acting push cylinder with a 120mm stroke. It extends via air pressure and retracts via an internal spring, yielding a fail-safe retracted home upon air loss. This CA-clevis variant delivers 539.9 N of usable push force at 0.5 MPa (791.1 N at 0.7 MPa). The exact drop-in replacement is the MSBL40X120SCA, matching the bore, stroke, G1/4 port, and mounting.
Upgrading to the MSBL40X120SCA swaps the MSAL's threaded covers for a riveted rolling-packed body. The -S magnet on this legacy SKU pairs with older CS1-M / DS1-M switches, whereas the MSBL uses CMSG / DMSG / EMSG sensors. End-of-stroke damping relies on a fixed rubber bumper, as single-acting designs lack adjustable cushions. The CA back cover provides a pivot pin joint to safely absorb arcing rod loads.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X120SCA Technical Specifications

| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X120SCA 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 MSAL40X120SCA Is Used
Stamping Press Ejector
Ejects formed sheet metal brackets from a 100-ton press bed. The 539.9 N push at 0.5 MPa clears the part, while the spring return guarantees the ejector retracts clear before the press cycles.
Pivoting Diverter Gate
Swings a heavy cardboard stream chute on a pivot pin. The CA clevis mount accommodates the arc geometry, and the fail-safe spring return parks the chute to a safe home position on air loss.
Bottle Capper Press
Applies 791.1 N of downward force at 0.7 MPa to seat screw caps on a packaging line. The fixed rubber bumper absorbs the repeated impact, protecting the thread caps from damage.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X120SCA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X120SCA
To replace this MSAL40X120SCA with the MSBL40X120SCA, verify your 40mm bore, 120mm stroke, G1/4 PT port, M12x1.25 rod thread, and CA clevis mount. Ensure your 3/2 valve delivers at least the 0.2 MPa minimum to overcome the return spring. If you need less force, the 32mm bore offers 317.7 N at 0.5 MPa; if you need more, step up to a 50mm bore. Note that 120mm strokes on compact bores risk rod bending—ensure strict lateral alignment. Never apply external load on the unpowered spring return stroke.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X120SCA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X120SCA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X120SCA FAQ
Yes, the MSAL40X120SCA is discontinued. The exact drop-in replacement is the MSBL40X120SCA, which matches the 40mm bore, 120mm stroke, G1/4 port, and CA clevis. The MSBL upgrades the body to a riveted rolling-packed design and changes the -S magnet compatibility from CS1-M / DS1-M switches to CMSG / DMSG / EMSG sensors.
This single-acting push cylinder delivers 539.9 N of usable force at 0.5 MPa and 791.1 N at 0.7 MPa (equivalent to roughly 80.7 kgf max). Because the internal spring opposes the air stroke, the minimum working pressure is 0.2 MPa. The fixed rubber bumper handles end-of-stroke damping, but it is not a lock—use an external device to hold a load mid-stroke.
