This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X20SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X20SU 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 MAL25 Aluminum Alloy Mini Cylinder MAL25X20SU
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X20SU is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 20mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X20SU, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X20SU
The AirTAC MAL25X20SU is a discontinued compact double-acting aluminum mini round cylinder with a 25mm bore and 20mm stroke. It delivers 245N of push force and 206N of pull force at 0.5 MPa. The exact drop-in replacement is the MBL25X20SU, which matches the original bore, stroke, output force, G1/8 port, and flat-end rear cover.
This legacy SKU includes a built-in magnet (-S) for position sensing and a U flat-end back cover for rigid mounting. The original MAL body uses threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed body. Additionally, the MAL -S magnet works with older CS1-M / DS1-M switches, while the MBL replacement requires current CMSG / DMSG / EMSG sensors. The bore uses a heterogeneous two-way seal that retains grease, paired with a self-lubricating front-cover bearing guide.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X20SU carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | — |
| Max (@1.0 MPa) | 50 kgf | |
The MBL25X20SU 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 MAL25 Aluminum Alloy Mini Cylinder MAL25X20SU Is Used
PCB Depaneling Router
Drives a cutting head in tight electronics manufacturing cells, using the 245N push force at 0.5 MPa to cleanly route 1.6mm thick printed circuit boards.
Carton Flap Tucking
Executes rapid 20mm tucks on small packaging lines, relying on the rigid U flat-end back cover to maintain alignment during high-speed 30-800 mm/s cycles.
Connector Insertion Press
Applies precise downward pressure to seat ribbon cable connectors into plastic housings, benefiting from the 10mm hard-chrome plated carbon-steel rod.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X20SU with MBL25X20SU
To replace the MAL25X20SU, order the MBL25X20SU to retain the 25mm bore, 20mm stroke, G1/8 port, and U flat-end cover. Because this SKU includes the -S magnet, you must update your sensing setup: the legacy CS1-M / DS1-M switches will not fit the MBL, so upgrade to CMSG / DMSG / EMSG sensors. If you need adjustable air cushioning at the stroke ends, step up to the MBLC variant, as the MAL only has a fixed rubber bumper.
For sizing, if 206N pull at 0.5 MPa is excessive, step down to the 20mm bore offering 132N pull. If you need more power, step up to the 32mm bore providing 346N pull. Note that a plain cylinder does not hold a load when air is lost; use an external rod lock or pilot-operated check valve for failsafe holding.
Upgrade checklist
- ✓ Order the MBL25X20SU (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 MBL25X20SU instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X20SU FAQ
Yes, the MAL25X20SU is discontinued. The exact drop-in replacement is the MBL25X20SU, offering the same 25mm bore, 20mm stroke, G1/8 port, and flat-end rear cover. You will need to update your sensors from the old CS1-M / DS1-M to the new CMSG / DMSG / EMSG family.
At 0.5 MPa, the push force is 245N and the pull force is 206N. At 0.7 MPa, the push force is 343N. The maximum theoretical force is 50 kgf at 1.0 MPa.
