This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X325SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X325SU 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 MAL25X325SU
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X325SU is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 325mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X325SU, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X325SU
The AirTAC MAL25X325SU is a discontinued double-acting aluminum mini round cylinder featuring a 25mm bore and 325mm stroke. It delivers 245N of push force and 206N of pull force at 0.5 MPa, utilizing a G1/8 port and an M10x1.25 rod-end thread. The exact drop-in replacement is the MBL25X325SU, which matches the original bore, stroke, output force, port size, and U flat-end back cover for a seamless transition.
This legacy SKU includes a built-in magnet (-S) for position detection and a U flat-end rear cover for rigid mounting. The original MAL body used threaded front and back covers, whereas the current MBL replacement features a riveted rolling-packed body. Additionally, the MAL -S magnet operates with the older CS1-M and DS1-M switches, while the MBL successor utilizes the current CMSG, DMSG, or EMSG sensor family. A fixed rubber bumper absorbs end-of-stroke impact, though it does not hold the load if air pressure is lost.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X325SU 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 MBL25X325SU 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 MAL25X325SU Is Used
PCB Conveyor Diverter
Pushes populated electronics boards sideways on a 325mm travel path, using the 245N push force to overcome carrier friction without damaging components.
Carton Labeling Gate
Acts as a compact stopper gate for small packaging boxes, where the U flat-end rear cover provides rigid, wobble-free blocking at the conveyor edge.
Textile Yarn Guide
Cycles a thread guide carriage across a 325mm width, relying on the self-lubricating front-cover bearing to maintain smooth operation during high-speed 30-800 mm/s movement.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X325SU with MBL25X325SU
To replace the MAL25X325SU, order the MBL25X325SU, ensuring you keep the S magnet, U flat-end back cover, and default PT thread. If you need to adjust the bore size, the next size down is the 20mm bore (providing 157N push at 0.5 MPa), and the next size up is the 32mm bore (providing 402N push at 0.5 MPa). Because this is a 325mm stroke, the 10mm rod is susceptible to bending under side loads; use an external guide rail or pivot mount to prevent rod damage. If you need end-of-stroke deceleration control, the fixed rubber bumper cannot be adjusted—upgrade to the MBLC series for an adjustable air cushion. Furthermore, a plain cylinder does not hold its position upon air loss; install an external pilot-operated check valve for load holding.
Upgrade checklist
- ✓ Order the MBL25X325SU (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 MBL25X325SU instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X325SU FAQ
Yes, the MAL25X325SU is discontinued. The exact drop-in replacement is the MBL25X325SU, which offers the same 25mm bore, 325mm stroke, 50 kgf max force, G1/8 port, and U flat-end mounting. The only changes are the riveted rolling-packed body and the switch to CMSG/DMSG/EMSG sensors.
At 0.5 MPa, the 25mm bore provides 245N of push force and 206N of pull force. At 0.7 MPa, the push force is 343N. The maximum theoretical force is 50 kgf at 1.0 MPa.
