This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL32X140U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL32X140U in place of this model. The MBL replacement upgrades to a riveted rolling-packed body and the current CMSG / DMSG / EMSG sensor switches (the MAL used CS1-M / DS1-M).
Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X140U
The AirTAC Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X140U is a double-acting aluminum-barrel mini round cylinder with a Ø32mm bore and 140mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL32X140U, which matches its bore, stroke, force and mounting.

About the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X140U
The AirTAC MAL32X140U is a discontinued double-acting aluminum mini round cylinder with a 32mm bore and 140mm stroke. It delivers 402N push and 346N pull at 0.5MPa, operating on a G1/8 port with an M10x1.25 rod thread. The exact drop-in replacement is the MBL32X140U, which matches the bore, stroke, force, port, and U flat-end mounting exactly.
This legacy MAL unit features threaded front and back covers, whereas the modern MBL utilizes a riveted rolling-packed body. The U code specifies a flat-end rear cover for rigid, non-arcing mounting. Because this SKU lacks the -S suffix, it has no internal magnet and cannot accept a position sensor. The fixed rubber bumper softens end-of-stroke impact but does not lock the rod.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL32X140U carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The MBL32X140U produces the same force from the same bore — a true drop-in on output. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X140U Is Used
PCB Router Z-Axis
Drives a 140mm vertical plunge for a depaneling router, using the 402N push force to cleanly cut separation tabs on populated circuit boards.
Carton Flap Folder
Actuates a 140mm folding arm on a compact packaging line, relying on the rigid U flat-end rear cover to maintain bracket alignment during high-speed cycling.
Test Socket Actuator
Pushes an IC test socket lid down 140mm in semiconductor testing, where the fixed rubber bumper absorbs the 346N pull contact without bouncing.
Replacing the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X140U with MBL32X140U
To replace the MAL32X140U, order the MBL32X140U. Verify your 32mm bore, 140mm stroke, G1/8 port, and PT tapered thread. The U flat-end back cover provides a rigid rear mount; if your machine requires arcing pivot motion, switch to a CA or CM cover on the MBL. Since this SKU lacks an -S magnet, it cannot support a sensor. If you need position detection, order the MBL32X140US and upgrade to the modern CMSG, DMSG, or EMSG switches, as the older CS1-M and DS1-M sensors are obsolete.
For sizing flexibility, stepping down to the 25mm bore yields 245N push at 0.5MPa, while stepping up to the 40mm bore provides 628N push at 0.5MPa. With a 140mm stroke, the 12mm carbon-steel rod has limited side-load tolerance; use an external guide rail to prevent rod bending. The plain cylinder does not hold position when air is lost, so add an external rod lock for suspended loads. If you need adjustable end-cushioning, specify the MBLC series instead of the standard MBL.
Upgrade checklist
- ✓ Order the MBL32X140U (same bore/stroke/force)
- ✓ Same G1/8 port and mounting accessories
- ✓ Sensor: swap CS1-M/DS1-M → CMSG/DMSG/EMSG
- ✓ Need a cushion? use MBLC (adjustable air cushion)
- ✓ 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 0.1 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Front/rear covers are threaded — not intended for field disassembly.
- check Use the correct mounting accessory (LB / FA / SDB) and back cover (CA / U / CM).
- check For new builds, specify the MBL32X140U instead of this discontinued model.
Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X140U FAQ
Yes, the AirTAC MAL32X140U is discontinued. The exact drop-in replacement is the MBL32X140U, which provides identical bore, stroke, force, G1/8 port, and U flat-end mounting. The MBL upgrades the body to a riveted rolling-packed design.
At 0.5MPa, the push force is 402N and the pull force is 346N. At 0.7MPa, the push force is 563N. The maximum theoretical force is 82kgf at 1.0MPa. The cylinder operates at 0.1-1.0MPa with a speed range of 30-800mm/s.
