This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL32X400-S-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL32X400-S-U 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 MAL32X400-S-U
The AirTAC Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X400-S-U is a double-acting aluminum-barrel mini round cylinder with a Ø32mm bore and 400mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL32X400-S-U, which matches its bore, stroke, force and mounting.

About the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X400-S-U
The AirTAC MAL32X400-S-U is a discontinued double-acting aluminum mini round cylinder with a 32mm bore and 400mm stroke. It delivers 402N push and 346N pull at 0.5MPa, operating at 30-800mm/s on a G1/8 port. The exact drop-in replacement is the MBL32X400-S-U, matching the force, port, and stroke perfectly.
This legacy unit features a U flat-end back cover for rigid mounting and a built-in -S magnet. The MAL uses threaded front and back covers, whereas the modern MBL utilizes a riveted rolling-packed body. Its heterogeneous two-way seal retains grease, while the 12mm carbon-steel rod has 20um hard chrome plating.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL32X400-S-U 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 MBL32X400-S-U 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 MAL32X400-S-U Is Used
PCB Router Z-Axis
Drives the vertical plunge on a compact PCB depaneling router, using the 346N pull at 0.5MPa to retract the 400mm stroke carbide bit safely.
Carton Flap Folder
Actuates a 400mm folding arm on a small packaging line, relying on the 402N push force to tuck heavy corrugated flaps closed.
Lathe Tailstock Ejector
Pushes bar stock out of a CNC lathe tailstock, where the rigid U flat-end cover withstands inline impact and the -S magnet confirms ejection.
Replacing the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X400-S-U with MBL32X400-S-U
To replace the MAL32X400-S-U, order the MBL32X400-S-U. Verify the 32mm bore, 400mm stroke, G1/8 port, PT thread, and U flat-end cover. Because this SKU includes the -S magnet, note that the older CS1-M/DS1-M switches are retired; the MBL uses CMSG/DMSG/EMSG sensors. The MAL uses a fixed rubber bumper; if adjustable cushioning is needed, step up to the MBLC.
At 400mm stroke, the 12mm rod is highly susceptible to bending under side-loads; use an external guide or pivot. If sizing down, the 25mm bore gives 245N push at 0.5MPa. If sizing up, the 40mm bore yields 628N push at 0.5MPa. A plain cylinder drifts when air is lost; add a rod lock for held loads.
Upgrade checklist
- ✓ Order the MBL32X400-S-U (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 MBL32X400-S-U instead of this discontinued model.
Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X400-S-U FAQ
Yes, the MAL32X400-S-U is discontinued. The exact drop-in replacement is the MBL32X400-S-U, offering the same 32mm bore, 400mm stroke, G1/8 port, and U flat-end mounting. The MBL upgrades the body to a riveted rolling-packed design and uses CMSG/DMSG/EMSG sensors for the -S magnet.
The 32mm bore delivers 402N push and 346N pull at 0.5MPa, 563N push at 0.7MPa, with a maximum theoretical force of 82kgf at 1.0MPa. It operates at 30-800mm/s and uses a fixed rubber bumper, not an adjustable cushion.
