This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL32X20U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL32X20U 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 MAL32X20U
The AirTAC Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X20U is a double-acting aluminum-barrel mini round cylinder with a Ø32mm bore and 20mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL32X20U, which matches its bore, stroke, force and mounting.

About the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X20U
The AirTAC MAL32X20U is a discontinued compact double-acting aluminum mini round cylinder. Delivering 402 N of push force at 0.5 MPa, it features a 32 mm bore, a 20 mm stroke, and a G1/8 port. The exact drop-in replacement is the MBL32X20U, which matches the original bore, stroke, output force, port size, and U flat-end mounting.
The legacy MAL body uses threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed body for equally robust performance. Because this specific SKU lacks the -S magnet option, it cannot accept a position sensor. The piston relies on a heterogeneous two-way seal that retains grease, running on a carbon-steel rod with 20 um hard-chrome plating.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL32X20U 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 MBL32X20U 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 MAL32X20U Is Used
PCB Drill Chuck Gate
Cycles a 402 N push at 0.5 MPa to open and close a protective chuck guard on a printed circuit board drilling rig.
IC Handler Ejector
Provides a fast 20 mm stroke to push tested integrated circuits out of a high-speed test socket.
Carton Flap Tucker
Uses its 346 N pull force to tuck minor inner flaps on small pharmaceutical cartons prior to sealing.
Replacing the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X20U with MBL32X20U
To replace the MAL32X20U, order the MBL32X20U. Confirm the 32 mm bore, 20 mm stroke, PT thread, and the rigid U flat-end back cover. If you require position sensing, you must select an MBL variant with an -S magnet, which will use the current CMSG / DMSG / EMSG switches rather than the older CS1-M / DS1-M sensors. The fixed rubber bumper softens end-of-stroke impacts; for adjustable air cushioning, step up to the MBLC series.
For sizing flexibility, stepping down to a 25 mm bore reduces thrust to 245 N at 0.5 MPa, while stepping up to a 40 mm bore increases thrust to 628 N at 0.5 MPa. Note that a plain cylinder does not hold its load when air is lost—the rod will drift. The 12 mm rod handles short 20 mm strokes easily without an external guide.
Upgrade checklist
- ✓ Order the MBL32X20U (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 MBL32X20U instead of this discontinued model.
