This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL32X550SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL32X550SU 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 MAL32X550SU
The AirTAC Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X550SU 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 MBL32X550SU, which matches its bore, stroke, force and mounting.

About the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X550SU
The AirTAC MAL32X550SU is a discontinued double-acting aluminum mini round cylinder with a 32mm bore and a 550mm stroke. Because 550mm exceeds the 500mm standard maximum, this is a non-standard, made-to-order length. It delivers 402N of push force and 346N of pull force at 0.5 MPa. The direct, drop-in replacement is the MBL32X550SU, which matches the exact bore, stroke, output force, G1/8 port, and U flat-end back cover.
This legacy unit features a U flat-end back cover for rigid mounting and a built-in -S magnet. The older MAL body uses threaded front and back covers, whereas the current MBL replacement uses a riveted rolling-packed body. Additionally, the -S magnet on this MAL works with legacy CS1-M or DS1-M switches, but upgrading to the MBL requires switching to CMSG, DMSG, or EMSG sensors. The cylinder uses a fixed rubber bumper, not an adjustable cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL32X550SU 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 MBL32X550SU 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 MAL32X550SU Is Used
PCB Panel Transfer
Pushes populated electronics trays along a 550mm conveyor section. The 402N thrust at 0.5 MPa easily moves the light aluminum fixtures, while the U flat-end cover handles the rigid frame mounting.
Carton Flap Folder
Actuates a 550mm arm to fold large corrugated box flaps. The non-standard stroke provides the extended reach needed for oversized packaging, relying on the 563N push force at 0.7 MPa for secure creasing.
Textile Beam Indexing
Shifts a warp beam 550mm into the loom staging area. The built-in -S magnet confirms the move via a CS1-M switch, though upgrading to the MBL will require updating to a CMSG sensor.
Replacing the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X550SU with MBL32X550SU
To replace the MAL32X550SU, order the MBL32X550SU. Verify your setup accommodates the 32mm bore, 550mm non-standard stroke, G1/8 port, and U flat-end back cover. If you do not need position sensing, you can drop the -S; otherwise, note that the MBL upgrade forces a sensor change from CS1-M/DS1-M to CMSG/DMSG/EMSG. If a cushion is required for the long stroke, step up to the MBLC series, as the MAL only has a fixed rubber bumper.
For sizing flexibility, stepping down to the 25mm bore yields 245N push at 0.5 MPa, while stepping up to the 40mm bore provides 628N push. Because the stroke is 550mm, the 12mm rod is highly susceptible to bending under side loads; you must use an external guide rail or a pivot mount. Furthermore, this cylinder will drift and drop its load if air pressure is lost, so install an external rod lock or pilot-operated check valve for vertical holding.
Upgrade checklist
- ✓ Order the MBL32X550SU (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 MBL32X550SU instead of this discontinued model.
Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X550SU FAQ
Yes, the MAL32X550SU is discontinued. The exact drop-in replacement is the MBL32X550SU, which offers the same 32mm bore, 550mm stroke, G1/8 port, U flat-end back cover, and -S magnet. The MBL uses a riveted rolling-packed body instead of threaded covers, and you must upgrade your sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG.
The 32mm bore provides a push force of 402N and a pull force of 346N at 0.5 MPa. At 0.7 MPa, the push force is 563N. The maximum theoretical force is 82 kgf at 1.0 MPa. Note that the 550mm stroke is a non-standard, made-to-order length exceeding the 500mm standard maximum.
