This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL32X550CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL32X550CM 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 MAL32X550CM
The AirTAC Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X550CM is a double-acting aluminum-barrel mini round cylinder with a Ø32mm bore and 550mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL32X550CM, which matches its bore, stroke, force and mounting.

About the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X550CM
The AirTAC MAL32X550CM is a discontinued double-acting aluminum mini round cylinder with a 32mm bore and a 550mm non-standard made-to-order stroke. It delivers 402N of push force and 346N of pull force at 0.5MPa. AirTAC replaced this legacy unit with the MBL32X550CM, a drop-in alternative retaining the exact same G1/8 port, M10x1.25 rod thread, and CM round-end back cover. This 550mm length exceeds the 500mm standard catalog limit, so it requires custom fabrication.
Because this SKU lacks the -S magnet option, it cannot accept a position sensor. The original MAL body uses threaded front and back covers, whereas the MBL replacement features a riveted rolling-packed body for the same footprint. Both generations rely on a fixed rubber bumper at stroke ends rather than an adjustable air cushion. The piston uses a heterogeneous two-way seal that retains grease, running against a carbon-steel rod with 20um hard-chrome plating.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL32X550CM 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 MBL32X550CM 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 MAL32X550CM Is Used
Carton Flap Folding
Drives a 550mm sweep arm to fold large corrugated carton flaps in a packaging line, utilizing the 402N push force at 0.5MPa to overcome board stiffness.
Textile Beam Indexing
Shifts heavy fabric beams laterally between processing stations, where the long stroke accommodates wide loom formats and the CM round-end allows slight arc alignment.
Vertical Tray Magazine Push
Ejects stacked product trays from a high magazine chute, requiring the full 550mm extension to clear the magazine throat before retraction.
Replacing the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X550CM with MBL32X550CM
To replace the MAL32X550CM, order the MBL32X550CM. Confirm the PT tapered port thread, the CM round-end back cover, and the lack of a magnet. If your machine requires position sensing, you must step up to an MBL32X550CMS and update your wiring, as the legacy MAL used CS1-M or DS1-M switches while the current MBL line uses CMSG, DMSG, or EMSG sensors. If you need adjustable end-of-stroke cushioning to absorb the kinetic energy of this long stroke, look at the MBLC32 variant, since the MAL only has a fixed rubber bumper.
When sizing this actuator, verify your force needs: stepping down to a 25mm bore drops output to 245N push at 0.5MPa, while stepping up to a 40mm bore increases it to 628N. Because the 550mm stroke is long and the 12mm rod is slender, side-load tolerance is low. You must use an external guide rail or pair this cylinder with a pivot mounting accessory to prevent rod bending. Note that a plain MAL or MBL does not hold its load when air pressure is lost; the rod will drift. Use an external rod lock or pilot-operated check valve if the load must remain suspended.
Upgrade checklist
- ✓ Order the MBL32X550CM (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 MBL32X550CM instead of this discontinued model.
Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X550CM FAQ
Yes, the MAL series is end-of-life. The exact drop-in replacement is the MBL32X550CM. It matches the 32mm bore, 550mm stroke, G1/8 port, CM round-end cover, and force ratings. The main physical change is that the MBL uses a riveted rolling-packed body instead of the threaded covers found on the MAL.
At 0.5MPa it provides 402N push and 346N pull; at 0.7MPa push is 563N, with a maximum theoretical force of 82kgf at 1.0MPa. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor. If sensing is required, order the MBL32X550CMS and use CMSG, DMSG, or EMSG switches.
