This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL32X55SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL32X55SU 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 MAL32X55SU
The AirTAC Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X55SU is a double-acting aluminum-barrel mini round cylinder with a Ø32mm bore and 55mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL32X55SU, which matches its bore, stroke, force and mounting.

About the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X55SU
The AirTAC MAL32X55SU is a discontinued double-acting aluminum mini round cylinder with a 32mm bore and 55mm stroke. It delivers 402N push and 346N pull at 0.5MPa using a 12mm carbon-steel rod with 20um hard chrome plating. The exact drop-in replacement is the MBL32X55SU, matching the bore, stroke, force, G1/8 port, and flat-end U back cover.
This legacy SKU features a built-in -S magnet for position sensing. The older MAL cylinder uses a threaded front and rear cover, while the modern MBL replacement uses a riveted rolling-packed body. The -S magnet on the MAL works with CS1-M and DS1-M switches, but upgrading to the MBL requires current CMSG, DMSG, or EMSG sensors. A heterogeneous two-way seal retains grease, and the self-lubricating front-cover bearing guide reduces wear over its 30-800mm/s speed range.
Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X55SU Technical Specifications

| Stroke | 55 mm |
| 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 MBL32X55SU 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 MBL32X55SU 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 MAL32X55SU Is Used
PCB Router Z-Axis
Drives the vertical plunge of a printed circuit board depaneling router, using the 402N push force to cleanly cut FR4 fiberglass substrates without flexing.
Carton Flap Folder
Folds the minor flaps on small pharmaceutical packaging cartons, where the 55mm stroke and rigid U flat-end mount keep the folding arm perfectly timed.
Lathe Chuck Gate
Actuates a sliding safety door on an automatic CNC lathe, using the -S magnet to confirm the gate is fully closed before the spindle starts.
Replacing the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X55SU with MBL32X55SU
To replace the MAL32X55SU, order the MBL32X55SU. Confirm your 55mm stroke, G1/8 port, and PT tapered thread form. The U flat-end back cover provides rigid rear mounting, unlike a CA pivot which allows arcing. Because this SKU includes the -S magnet, note that your older CS1-M or DS1-M switches will not fit the MBL; you must upgrade to CMSG, DMSG, or EMSG sensors. The MAL uses a fixed rubber bumper, so if your application needs adjustable end-of-stroke damping, step up to the current MBLC variant.
For sizing, if you need less force, step down to the 25mm bore (245N push at 0.5MPa). If you need more power, step up to the 40mm bore (628N push at 0.5MPa). A plain cylinder does not hold its load when air is lost; the rod drifts and the bumper only softens impact, so add an external rod lock or pilot-operated check valve for position holding.
Upgrade checklist
- ✓ Order the MBL32X55SU (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 MBL32X55SU instead of this discontinued model.
Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X55SU FAQ
Yes, the MAL32X55SU is discontinued. The exact drop-in replacement is the MBL32X55SU, which matches the 32mm bore, 55mm stroke, G1/8 port, and U flat-end mounting. The MBL uses a riveted rolling-packed body instead of the older threaded covers.
At 0.5MPa it provides 402N push and 346N pull; at 0.7MPa it provides 563N push, with a maximum theoretical force of 82kgf at 1.0MPa. The -S magnet works with older CS1-M and DS1-M switches, but the MBL replacement requires CMSG, DMSG, or EMSG sensors.
