This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL40X100SCA, 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 MSAL40X100SCA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X100SCA 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 direct replacement is the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X100SCA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X100SCA
The AirTAC MSAL40X100SCA is a discontinued single-acting push, spring-return mini cylinder. Air extends the Ø40 mm rod for the 100 mm work stroke, while an internal spring retracts it to a fail-safe home when air is released. It delivers a usable push force of 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa. The direct replacement is the MSBL40X100SCA, matching the bore, stroke, G1/4 port, and CA clevis.
This SKU includes the -S magnet for position sensing, originally designed for the older CS1-M or DS1-M reed switches; the MSBL successor uses the newer CMSG, DMSG, or EMSG families. The MSAL features threaded covers and a fixed rubber bumper for end-of-stroke damping, whereas the MSBL upgrade uses a riveted rolling-packed body. A minimum 0.2 MPa operating pressure is required to overcome the return spring, and no external load should be applied to the spring return stroke.

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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X100SCA 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 MSAL40X100SCA Is Used
Stamping Press Ejector
Ejects formed sheet metal brackets from a die using 539.9 N of push force at 0.5 MPa, relying on the spring return to safely retract the pin during air loss.
Woodworking Clamp Arm
Extends 100 mm to hold a door panel during routing, where the CA clevis accommodates the pivot arc and the fixed rubber bumper absorbs the impact.
Packaging Diverter Gate
Pushes cardboard cartons onto a secondary conveyor lane; the fail-safe spring return ensures the gate clears the line if the 0.2 MPa minimum air supply drops.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X100SCA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X100SCA
To replace this MSAL40X100SCA, use the direct replacement MSBL40X100SCA. Confirm the 40 mm bore, 100 mm stroke, G1/4 port, PT thread, CA pivot/clevis back cover, and the -S magnet (noting the sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG). Maintain the 0.2 MPa minimum air pressure to beat the return spring, and never apply external load on the return stroke. Stepping down, the 32 mm bore provides 317.7 N at 0.5 MPa; stepping up is not an option as 40 mm is the largest in this mini series. Because this 100 mm stroke is long for a 40 mm bore, watch for side-load and rod-bending forces during extension.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X100SCA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X100SCA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X100SCA FAQ
Yes, the MSAL40X100SCA is discontinued. The direct replacement is the MSBL40X100SCA, which matches the 40 mm bore, 100 mm stroke, G1/4 port, CA clevis, and single-acting push function. You will only need to update your position sensors from the older CS1-M/DS1-M to the CMSG/DMSG/EMSG family.
The usable push force, already net of the opposing return spring, is 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa. It requires a minimum operating pressure of 0.2 MPa to overcome the internal spring and extend the rod.
