This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X125SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X125SCA 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 MSAL40X125SCA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X125SCA is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø40mm bore and 125mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X125SCA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X125SCA
The AirTAC MSAL40X125SCA is a discontinued single-acting push cylinder with a 40mm bore and 125mm stroke. Air extends the rod to do work, while an internal spring retracts it to a fail-safe home when air is removed. It delivers 539.9 N of usable push force at 0.5 MPa and 791.1 N at 0.7 MPa. The exact drop-in replacement is the MSBL40X125SCA, matching the bore, stroke, G1/4 port, and CA mounting.
This SKU includes the -S magnet for position sensing. The older MSAL uses CS1-M or DS1-M reed switches, whereas the MSBL upgrade accepts CMSG, DMSG, or EMSG sensors. The MSAL features threaded covers, while the MSBL utilizes a riveted rolling-packed body. This unit has a fixed rubber bumper for end-of-stroke damping and a PT tapered port thread. The CA back cover provides a pivot clevis that swings on a pin, making it ideal for arcing or pivoting loads.

| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X125SCA 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 MSAL40X125SCA Is Used
Stamping Press Ejection
Ejects formed sheet metal brackets from a stamping die. The 539.9 N push force at 0.5 MPa reliably clears the part, while the spring return ensures the ejector retracts clear of the next blank.
Pivoting Gate Diverter
Uses the CA pivot clevis to swing a heavy guide gate on a packaging line, routing cartons down a secondary chute when air is applied and safely defaulting to the main line on air loss.
Woodworking Clamp Arm
Extends to hold an oak workpiece against a CNC router fence. The fail-safe spring return releases the clamp automatically if the air supply drops, preventing workpiece damage.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X125SCA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X125SCA
To replace this MSAL40X125SCA, order the MSBL40X125SCA. Confirm the 40mm bore, 125mm stroke, G1/4 port, PT thread, CA pivot clevis, and -S magnet are correct for your jig. Remember that the MSBL requires CMSG, DMSG, or EMSG switches instead of the older CS1-M/DS1-M sensors. Operating pressure must be at least 0.2 MPa to overcome the return spring, and you must apply no external load on the spring return stroke.
If you need to adjust your force capacity, step down to a 32mm bore (317.7 N push at 0.5 MPa) for lighter tasks, or step up to a larger standard profile if you require significantly more thrust. Because this 125mm stroke is relatively long for a 40mm bore, carefully check side-load alignment to prevent rod-bending and premature seal wear.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X125SCA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X125SCA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X125SCA FAQ
Yes, the MSAL40X125SCA is discontinued. The exact drop-in replacement is the MSBL40X125SCA, matching the 40mm bore, 125mm stroke, G1/4 port, CA pivot clevis, and single-acting push function. You will need to upgrade your position sensors, as the MSBL uses CMSG, DMSG, or EMSG switches instead of the older CS1-M or DS1-M reed switches.
The usable push force is 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa. The maximum push force is approximately 80.7 kgf. The minimum operating pressure is 0.2 MPa, which is required to overcome the internal return spring. This cylinder uses a fixed rubber bumper, not an adjustable cushion, and cannot hold a load mid-stroke without an external mechanical lock.
