This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL32X275SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL32X275SU 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 MAL32X275SU
The AirTAC Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X275SU is a double-acting aluminum-barrel mini round cylinder with a Ø32mm bore and 275mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL32X275SU, which matches its bore, stroke, force and mounting.

About the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X275SU
The AirTAC MAL32X275SU is a discontinued double-acting aluminum mini round cylinder delivering 402 N of push force at 0.5 MPa. Built for compact spaces, it features a 32 mm bore, a 275 mm stroke, and a G1/8 port. AirTAC replaced this legacy unit with the MBL32X275SU, a drop-in alternative retaining the exact same output, porting, and mounting interface.
This specific SKU includes a U flat-end back cover for rigid rear mounting and a built-in magnet (-S) for position sensing. The original MAL body uses threaded front and back covers, whereas the newer MBL features a riveted rolling-packed body. Furthermore, the -S magnet on this cylinder interfaces with legacy CS1-M or DS1-M switches, while the MBL replacement transitions to the current CMSG, DMSG, or EMSG sensor families.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL32X275SU 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 MBL32X275SU 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 MAL32X275SU Is Used
PCB Conveyor Diversion
Pushes lightweight routing gates on a printed circuit board conveyor using 402 N of thrust at 0.5 MPa, fitting easily into tight transfer cells.
Semiconductor Wafer Cassette Stop
Acts as a hard stop for wafer cassettes, relying on the 275 mm stroke to clear the workspace during robotic loading and unloading.
Packaging Carton Flap Folder
Folds minor flaps on small packaging cartons, where the U flat-end rear cover provides a rigid brace against repetitive impact forces.
Replacing the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X275SU with MBL32X275SU
To replace this MAL32X275SU, order the MBL32X275SU and verify your 32 mm bore, 275 mm stroke, G1/8 port, and PT thread form. You must also account for the sensor transition: the -S magnet here requires older CS1-M / DS1-M reed switches, but the MBL successor utilizes CMSG / DMSG / EMSG solid-state sensors. The U flat-end back cover provides a rigid, fixed rear mounting point.
If you need to adjust your force output, stepping down to the 25 mm bore yields 245 N of push at 0.5 MPa, while stepping up to the 40 mm bore provides 628 N. Because the 275 mm stroke exceeds 300 mm, the 12 mm rod is susceptible to bending under lateral stress; utilize an external guide rail or a pivot mount to absorb side loads. Note that the fixed rubber bumper softens end-of-stroke impact but does not lock the rod, and the MAL lacks adjustable cushioning—a feature only found on the current MBLC line.
Upgrade checklist
- ✓ Order the MBL32X275SU (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 MBL32X275SU instead of this discontinued model.
Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X275SU FAQ
Yes, the MAL32X275SU is discontinued. The exact drop-in replacement is the MBL32X275SU, which matches the 32 mm bore, 275 mm stroke, G1/8 port, and U flat-end mounting. The MBL uses a riveted body instead of threaded covers, and if you use the -S magnet, you must upgrade from the old CS1-M / DS1-M switches to the CMSG / DMSG / EMSG series.
At 0.5 MPa, the push force is 402 N and the pull force is 346 N. At 0.7 MPa, the push force increases to 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa. It operates at speeds between 30 and 800 mm/s, functioning as a double-acting cylinder with a fixed rubber bumper.
