This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL32X40U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL32X40U 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 MSAL32X40U
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL32X40U is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø32mm bore and 40mm stroke, G1/8 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL32X40U.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL32X40U
The AirTAC MSAL32X40U is a discontinued single-acting push-type cylinder with a 32 mm bore and 40 mm stroke. Air extends the rod to perform work, while an internal spring retracts it, providing a fail-safe retracted home position upon air loss. This U-version features a flat-end back cover and a PT-threaded G1/8 port. Its usable push force is 317.7 N at 0.5 MPa and 478.5 N at 0.7 MPa, with a minimum operating pressure of 0.2 MPa required to overcome the return spring.
The exact drop-in replacement is the MSBL32X40U, matching the bore, stroke, force, and mounting. This MSAL features a threaded body cover and, lacking the -S suffix, cannot accept a position sensor. The modern MSBL upgrades to a riveted rolling-packed body; if sensing is needed on the new line, the MSBL-S uses CMSG, DMSG, or EMSG switches rather than the older CS1-M or DS1-M. End-of-stroke deceleration relies on a fixed rubber bumper, not an adjustable cushion.

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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL32X40U carries the same single-acting ratings.
Usable Push Force (Ø32mm)
| Pressure | Push force (net of spring) |
|---|---|
| 0.5 MPa | 317.7 N |
| 0.7 MPa | 478.5 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 MSAL32X40U Is Used
CNC Lathe Chuck Ejection
Ejects finished aluminum shafts from a CNC lathe collet. The 317.7 N push force at 0.5 MPa reliably knocks the part loose, while the spring return ensures the ejector clears the work area when air is cut for door opening.
PCB Router Waste Diversion
Actuates a diverter gate on a printed circuit board routing machine to sweep fiberglass dust into the waste bin. The flat-end U back cover mounts flush to the machine frame, and the fail-safe spring return parks the gate open during e-stop.
Stamping Press Blank Stop
Blocks steel blanks in a mechanical stamping press feed line. The 478.5 N force at 0.7 MPa halts the strip securely, and the fixed rubber bumper absorbs the impact without requiring manual adjustment.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL32X40U with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL32X40U
To replace this MSAL32X40U, specify the MSBL32X40U and confirm the 32 mm bore, 40 mm stroke, G1/8 PT port, and flat-end U back cover. Because this SKU lacks the -S magnet, it cannot support a position sensor; if your retrofit requires end-of-stroke detection, step up to an MSBL32X40US and use the modern CMSG, DMSG, or EMSG switch family. Remember that the single-acting design requires a minimum 0.2 MPa air pressure to overcome the internal spring, and you must never apply an external load on the spring return stroke.
If you need to adjust the force output, step down to the 25 mm bore (MSBL25X40U), which provides 176.4 N of push at 0.5 MPa, or step up to the 40 mm bore (MSBL40X40U), which yields 539.9 N at 0.5 MPa via its larger G1/4 port. For a 40 mm stroke on a 32 mm bore, side-load and rod-bending risks are minimal, but always ensure rigid front and rear mounting to preserve the self-lubricating guide.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL32X40U (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL32X40U instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL32X40U FAQ
Yes, the MSAL32X40U is discontinued. The exact drop-in replacement is the MSBL32X40U, which matches the 32 mm bore, 40 mm stroke, 317.7 N push force at 0.5 MPa, G1/8 port, and flat-end U back cover. The MSBL upgrades the construction to a riveted rolling-packed body.
The MSAL32X40U provides a usable push force of 317.7 N at 0.5 MPa and 478.5 N at 0.7 MPa (equivalent to roughly 48.8 kgf maximum). It requires a minimum operating pressure of 0.2 MPa to overcome the return spring and operates on single-acting push logic where air extends the rod and the spring retracts it.
