This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X40SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X40SCA 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 MSAL40X40SCA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X40SCA is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø40mm bore and 40mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X40SCA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X40SCA
The AirTAC MSAL40X40SCA is a discontinued single-acting push cylinder with a 40mm bore and 40mm stroke. Air extends the rod for the work cycle, while an internal spring retracts it to a fail-safe home when air is removed. Because the spring opposes the air stroke, the usable push force is 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa. The exact drop-in replacement is the MSBL40X40SCA, matching the bore, stroke, G1/4 port, and CA clevis mount.
This SKU includes the -S magnet for position sensing with older CS1-M or DS1-M reed switches; the MSBL replacement upgrades this to CMSG, DMSG, or EMSG sensors. The MSAL uses threaded covers and a fixed rubber bumper, while the MSBL features a riveted rolling-packed body. The CA back cover provides a pivot clevis that swings on a pin to absorb arcing load paths. Minimum working pressure is 0.2 MPa to overcome the return spring, and no external load should be applied on the spring return stroke.

| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X40SCA 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 MSAL40X40SCA Is Used
Stamping Press Ejector
Ejects formed sheet metal brackets from a stamping die using 539.9 N of push force at 0.5 MPa, relying on the spring return to clear the die for the next cycle.
Woodworking Gate Deflector
Pushes a diverter gate to route wood trim pieces down a reject chute, with the CA clevis absorbing the arcing load and the spring returning the gate to home on air loss.
Packaging Flap Tucking
Tucks cardboard flaps on a carton sealer using the 40mm bore power, where the fixed rubber bumper absorbs the end-of-stroke impact and the spring retracts the rod for carton clearance.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X40SCA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X40SCA
Replace this MSAL with the MSBL40X40SCA, confirming the 40mm bore, 40mm stroke, PT G1/4 port, M12x1.25 rod thread, CA pivot clevis, and -S magnet. Remember the sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG. Ensure your air supply meets the 0.2 MPa minimum to overcome the spring, and never apply external load on the return stroke. The fixed rubber bumper requires no adjustment.
To size correctly, step down to the 32mm bore if you need less force (317.7 N push at 0.5 MPa), or step up if you need more power (the 40mm is the largest in this mini series). At 40mm stroke, side-load and rod-bending risks are low, but keep the load axially aligned to protect the 16mm hard-chrome rod and front-cover guide.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X40SCA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X40SCA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X40SCA FAQ
Yes, the MSAL40X40SCA is discontinued. The exact drop-in replacement is the MSBL40X40SCA, which matches the 40mm bore, 40mm stroke, G1/4 port, CA clevis, and force class. 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 provides a usable push force of 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa (equivalent to roughly 80.6 kgf max). The operating pressure range is 0.2-1.0 MPa, with a 0.2 MPa minimum required to overcome the internal return spring. It uses a fixed rubber bumper, not an adjustable cushion.
