This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL32X420SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL32X420SU 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 MAL32X420SU
The AirTAC Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X420SU is a double-acting aluminum-barrel mini round cylinder with a Ø32mm bore and 420mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL32X420SU, which matches its bore, stroke, force and mounting.

About the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X420SU
The AirTAC MAL32X420SU is a discontinued double-acting aluminum mini round cylinder with a 32mm bore and 420mm stroke. It delivers 402N push and 346N pull at 0.5MPa, featuring a Ø12mm carbon-steel rod with 20um hard chrome plating and a self-lubricating front-cover bearing guide. The exact drop-in replacement is the MBL32X420SU, matching the bore, stroke, force, G1/8 port, and U flat-end rear cover.
This legacy unit uses a fixed rubber bumper and a heterogeneous two-way grease-retaining seal. The original threaded front and back covers are upgraded to a riveted rolling-packed body on the MBL. Because this SKU includes the -S magnet, note that the older CS1-M / DS1-M switches are replaced by the CMSG / DMSG / EMSG sensor family on the current MBL line.
Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X420SU Technical Specifications

| Acting type | Double acting |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.1 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Fixed rubber bumper |
| Max standard stroke | Up to 500 mm |
Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL32X420SU 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 MBL32X420SU 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 MAL32X420SU Is Used
PCB Router Z-Axis
Drives a 402N routing head up and down across a 420mm travel range for multi-layer circuit board profiling.
Carton Flap Folder
Actuates a 420mm stroke arm to fold corrugated box flaps, relying on the rigid U flat-end cover for stable mounting.
Battery Cell Tray Shuttle
Shifts lightweight battery trays between test stations using the 346N pull force at 0.5MPa over a 420mm distance.
Replacing the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X420SU with MBL32X420SU
To replace the MAL32X420SU, order the MBL32X420SU. Verify the 32mm bore, 420mm stroke, G1/8 port, and PT thread form. The U flat-end back cover provides a rigid rear mount, while the -S magnet requires upgrading your CS1-M / DS1-M switches to CMSG / DMSG / EMSG sensors. If you need to step down, the 25mm bore offers 245N push at 0.5MPa; stepping up to the 40mm bore provides 628N push at 0.5MPa. The fixed rubber bumper is not an adjustable cushion; for shock absorption order the MBLC. A plain cylinder drifts when air is lost, so use an external rod lock for position holding. At 420mm, the 12mm rod is highly susceptible to bending; pair it with an external guide rail to manage side loads.
Upgrade checklist
- ✓ Order the MBL32X420SU (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 MBL32X420SU instead of this discontinued model.
Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X420SU FAQ
Yes, the MAL32X420SU is discontinued. The exact drop-in replacement is the MBL32X420SU, which matches the 32mm bore, 420mm stroke, G1/8 port, U flat-end cover, and mounting dimensions. The new MBL uses a riveted body instead of threaded covers.
At 0.5MPa it provides 402N push and 346N pull; at 0.7MPa it provides 563N push, with a max theoretical force of 82kgf at 1.0MPa. The -S magnet on this MAL works with older CS1-M / DS1-M switches, but the MBL replacement requires CMSG / DMSG / EMSG sensors.
