This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X50SCM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X50SCM 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 MSAL40X50SCM
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X50SCM is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø40mm bore and 50mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X50SCM.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X50SCM
The AirTAC MSAL40X50SCM is a discontinued single-acting push, spring-return mini cylinder. Air extends the rod for the work stroke, while an internal spring retracts it to a fail-safe home when air is released. At bore 40, it delivers a usable push force of 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa. The exact drop-in replacement is the MSBL40X50SCM, matching the 50 mm stroke, G1/4 port, and CM round-end cover.
This SKU includes the -S magnet, which uses the older CS1-M / DS1-M switches; the MSBL replacement upgrades to CMSG / DMSG / EMSG sensors. The MSAL features threaded covers and a fixed rubber bumper, whereas the current MSBL uses a riveted rolling-packed body. A minimum of 0.2 MPa is required to overcome the return spring, and no external load should be applied on the 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X50SCM 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 MSAL40X50SCM Is Used
Stamping Press Ejector
Ejects small stamped metal parts from a die using 539.9 N at 0.5 MPa, with the spring ensuring the ejector pin retracts clear of the tooling on air loss.
Woodworking Door Clamp
Holds a cabinet door flat against a router table fence for edge profiling; the single-acting push provides firm hold and the fail-safe home releases the wood safely.
Packaging Flap Folder
Folds cardboard carton flaps on a packaging line, where the G1/4 port provides ample flow for rapid 50 mm extension and the spring returns the folder arm reliably.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X50SCM with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X50SCM
To replace the MSAL40X50SCM, order the MSBL40X50SCM. Confirm the 40 mm bore, 50 mm stroke, G1/4 port, PT thread, CM round-end cover, and FA mounting. Remember the -S magnet sensor family changes from CS1-M / DS1-M to CMSG / DMSG / EMSG. Stepping down to the 32 mm bore yields 317.7 N at 0.5 MPa, while stepping up is unavailable as 40 mm is the largest in this mini series. At 50 mm stroke, side-load and rod-bending risks are minimal, but always guide the load. Maintain at least 0.2 MPa working pressure and apply no external load on the spring return stroke.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X50SCM (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X50SCM instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X50SCM FAQ
Yes, the MSAL40X50SCM is discontinued. The exact drop-in replacement is the MSBL40X50SCM, which matches the 40 mm bore, 50 mm stroke, G1/4 port, CM cover, and mounting. The MSBL upgrades the body to a riveted rolling-packed design and changes the -S magnet switches from CS1-M / DS1-M to CMSG / DMSG / EMSG.
The usable single-acting push force (net of the return spring) is 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa. The operating pressure range is 0.2-1.0 MPa, requiring a minimum of 0.2 MPa to overcome the internal return spring. The maximum equivalent force is roughly 80.7 kgf at 0.7 MPa.
