This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL32X280SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL32X280SU 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 MAL32X280SU
The AirTAC Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X280SU is a double-acting aluminum-barrel mini round cylinder with a Ø32mm bore and 280mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL32X280SU, which matches its bore, stroke, force and mounting.

About the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X280SU
The AirTAC MAL32X280SU is a discontinued double-acting aluminum mini round cylinder. As a 32mm bore unit, it delivers a push force of 402 N and a pull force of 346 N at 0.5 MPa. The exact drop-in replacement is the MBL32X280SU, which matches the original 280mm stroke, G1/8 port, flat-end U cover, and magnet configuration perfectly.
This legacy model features a 12mm carbon-steel rod with 20 um hard chrome plating, guided by a self-lubricating front-cover bearing. The piston relies on a heterogeneous two-way seal that retains grease for long service life. Because this SKU includes the -S magnet, it was designed for CS1-M or DS1-M position sensors; upgrading to the MBL requires switching to the current CMSG, DMSG, or EMSG switch families. The older MAL body used threaded front and back covers, whereas the modern MBL uses a riveted rolling-packed body for identical ratings.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL32X280SU 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 MBL32X280SU 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 MAL32X280SU Is Used
PCB Panel Ejection
Pushes populated circuit boards out of an SMT line using 402 N of force at 0.5 MPa over a 280mm travel distance.
Wafer Cassette Loading
Inserts silicon wafers into processing cassettes where the 280mm stroke and rigid U flat-end cover ensure precise linear placement.
Carton Flap Folding
Folds small packaging flaps on a filling machine, benefiting from the compact 32mm aluminum body in tight transfer zones.
Replacing the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X280SU with MBL32X280SU
To replace the MAL32X280SU, order the MBL32X280SU and note the sensor family change from CS1-M/DS1-M to CMSG/DMSG/EMSG. If you need a softer end-of-stroke stop than the fixed rubber bumper provides, step up to the MBLC which adds an adjustable air cushion. If sizing down, the 25mm bore offers 245 N push at 0.5 MPa; if sizing up, the 40mm bore provides 628 N push at 0.5 MPa.
With a 280mm stroke on a 12mm rod, side-load tolerance is low and the rod is susceptible to bending. Use an external guide rail or a pivot bracket to support the load. A plain cylinder does not hold its position when air is lost; add an external rod lock or pilot-operated check valve for fail-safe load holding.
Upgrade checklist
- ✓ Order the MBL32X280SU (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 MBL32X280SU instead of this discontinued model.
Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X280SU FAQ
Yes, the MAL32X280SU is discontinued. The exact drop-in replacement is the MBL32X280SU, which matches the 32mm bore, 280mm stroke, G1/8 port, U flat-end cover, and -S magnet. The new MBL uses a riveted body instead of threaded covers, and you must upgrade your sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG.
The 32mm bore uses a G1/8 port and a 12mm rod. At 0.5 MPa it provides 402 N push and 346 N pull. At 0.7 MPa the push force is 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa.
