This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL40X120SCA, 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 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 direct 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 direct 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.

| 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 direct 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.
