This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL32X140SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL32X140SU 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 MAL32X140SU
The AirTAC Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X140SU 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 MBL32X140SU, which matches its bore, stroke, force and mounting.

About the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X140SU
The AirTAC MAL32X140SU is a discontinued double-acting aluminum mini round cylinder with a 32 mm bore and 140 mm stroke. It delivers 402 N of push force and 346 N of pull force at 0.5 MPa. The exact drop-in replacement is the MBL32X140SU, matching the bore, stroke, output, G1/8 port, and U flat-end cover. The legacy MAL features a threaded front and rear cover assembly, whereas the current MBL utilizes a riveted rolling-packed body for structural rigidity.
This specific SKU includes a built-in magnet (-S) for position sensing. On the MAL, this magnet interfaces with the older CS1-M and DS1-M reed switches; upgrading to the MBL requires migrating to the modern CMSG, DMSG, or EMSG sensor families. Internally, a heterogeneous two-way seal retains grease, and the carbon-steel rod is protected by 20 um hard-chrome plating. The stroke runs against a fixed rubber bumper, which softens end-of-travel impacts but does not function as an adjustable air cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL32X140SU 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 MBL32X140SU 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 MAL32X140SU Is Used
PCB Router Ejection
Deploys 402 N at 0.5 MPa to push singulated printed circuit boards out of a routing nest, utilizing the 140 mm stroke to clear the machine guard.
Carton Flap Folder
Actuates a mechanical arm to tuck minor flaps on small packaging lines, where the U flat-end cover mounts rigidly to a stationary frame bracket.
Connector Insertion Press
Provides the 346 N pull force and precise 140 mm retraction needed to seat ribbon cable connectors into housing slots without damaging delicate pins.
Replacing the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X140SU with MBL32X140SU
To replace the MAL32X140SU, order the MBL32X140SU. Confirm the 32 mm bore, 140 mm stroke, G1/8 port, and default PT tapered thread are retained. The U flat-end back cover provides a rigid, non-pivoting rear mount. Because this SKU has the -S magnet, plan to update your sensing architecture: the legacy CS1-M and DS1-M switches will not fit the MBL, so select current CMSG, DMSG, or EMSG sensors. If your application requires precise end-of-stroke deceleration rather than a standard rubber bumper, step up to the MBLC variant on the current line for an adjustable air cushion.
For sizing flexibility, step down to a 25 mm bore if you need less force (245 N push at 0.5 MPa), or step up to a 40 mm bore for heavier loads (628 N push at 0.5 MPa). At 140 mm of stroke, side-load tolerance is moderate given the 12 mm rod diameter. If the guided load cannot be perfectly aligned, use external guide rails to prevent rod bending. Note that a plain cylinder does not hold position if air pressure drops; add an external rod lock for fail-safe load holding.
Upgrade checklist
- ✓ Order the MBL32X140SU (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 MBL32X140SU instead of this discontinued model.
Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X140SU FAQ
Yes, the MAL32X140SU is discontinued. The exact drop-in replacement is the MBL32X140SU, which matches the 32 mm bore, 140 mm stroke, G1/8 port, and U flat-end cover. The MBL uses a riveted rolling-packed body instead of the older threaded covers, but maintains the same output force and mounting footprint.
At 0.5 MPa, the push force is 402 N and the pull force is 346 N. At 0.7 MPa, the push force is 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa. This model includes a -S magnet for position detection; on the MAL it works with CS1-M and DS1-M switches, but the MBL replacement requires CMSG, DMSG, or EMSG sensors.
