This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL32X120U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL32X120U 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 MAL32X120U
The AirTAC Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X120U is a double-acting aluminum-barrel mini round cylinder with a Ø32mm bore and 120mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL32X120U, which matches its bore, stroke, force and mounting.

About the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X120U
The AirTAC MAL32X120U is a discontinued double-acting aluminum mini round cylinder with a 32 mm bore and 120 mm stroke. It delivers 402 N of push force and 346 N of pull force at 0.5 MPa, utilizing a 12 mm carbon-steel rod with 20 um hard-chrome plating. AirTAC replaced this legacy unit with the MBL32X120U, a drop-in alternative that matches the exact bore, stroke, output force, G1/8 port, and U flat-end back cover. Because this specific SKU lacks an -S magnet, it cannot support a position sensor.
The original MAL body featured threaded front and back covers, whereas the modern MBL replacement utilizes a riveted rolling-packed body for equally rigid performance. This cylinder relies on a fixed rubber bumper to soften end-of-stroke impacts and uses a heterogeneous two-way seal that retains grease. Note that the bumper is not a locking mechanism; the rod will drift if air pressure is lost, so an external rod lock is required to hold a load safely.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL32X120U 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 MBL32X120U 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 MAL32X120U Is Used
PCB Conveyor Diverter
Pushes lightweight routing gates on a printed circuit board conveyor using 402 N of force, fitting easily into tight machine gaps.
Chip Tray Ejector
Extends 120 mm to eject semiconductor test trays from a docking station, relying on the rigid U flat-end back cover for stable mounting.
Small Part Stamper
Provides 346 N of pull force to retract a small mechanical marking stamp from thin aluminum sheet metal in an assembly cell.
Replacing the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X120U with MBL32X120U
To replace the discontinued MAL32X120U, order the MBL32X120U, ensuring you keep the PT tapered port thread, the U flat-end back cover, and the standard double-acting configuration. If you need position sensing, you must step up to an -S variant on the MBL line, which transitions from the old CS1-M / DS1-M switches to the current CMSG / DMSG / EMSG sensors. If 402 N of push at 0.5 MPa is too much force, step down to the 25 mm bore (245 N push); if you need more power, step up to the 40 mm bore (628 N push). If your application requires adjustable end-cushioning rather than the fixed rubber bumper, specify the MBLC32 series. Since the 120 mm stroke is below the 300 mm threshold, side-load stress is minimal, but always verify rod alignment to prevent premature bearing wear.
Upgrade checklist
- ✓ Order the MBL32X120U (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 MBL32X120U instead of this discontinued model.
Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X120U FAQ
Yes, the MAL32X120U is discontinued. The exact drop-in replacement is the MBL32X120U, which shares the same 32 mm bore, 120 mm stroke, force output, G1/8 port, and U flat-end back cover. The main physical change is that the MBL uses a riveted rolling-packed body instead of the threaded covers found on the MAL.
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. The cylinder cannot hold its position when air is lost because the fixed rubber bumper only softens the stroke end and does not act as a lock.
