This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X145SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X145SU 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 MAL25X145SU
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X145SU is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 145mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X145SU, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X145SU
The AirTAC MAL25X145SU is a discontinued double-acting aluminum mini round cylinder with a 25mm bore and 145mm stroke. It delivers 245N push and 206N 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 MBL25X145SU, which matches the original bore, stroke, output force, port size, and U flat-end back cover for a seamless transition.
This legacy model features a U flat-end back cover for rigid rear mounting and a built-in magnet (-S) for position sensing. An important upgrade detail is that the older MAL uses threaded front and back covers on the barrel, whereas the current MBL replacement utilizes a riveted rolling-packed body. Additionally, the -S magnet on this MAL functions with the older CS1-M and DS1-M reed switches, while the MBL replacement requires the modern CMSG, DMSG, or EMSG sensor families.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X145SU 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 MBL25X145SU 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 MAL25X145SU Is Used
PCB Router Z-Axis
Drives the vertical plunge of a small PCB routing spindle using 245N of thrust at 0.5 MPa over 145mm to cut through FR4 fiberglass substrates.
Carton Flap Folder
Deploys a mechanical flap-folding arm on a packaging conveyor, utilizing the U flat-end rigid mount to absorb the 206N pull load during retraction.
Tray Pusher Ejector
Pushes filled blister packs from a filling machine outlet into a secondary carton, requiring the 343N push force available at 0.7 MPa for sticky product release.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X145SU with MBL25X145SU
To replace the MAL25X145SU, order the MBL25X145SU, ensuring you keep the 25mm bore, 145mm stroke, G1/8 port, PT thread, and U flat-end cover. Because this SKU includes a magnet (-S), note that the MBL successor mandates a sensor family change from the legacy CS1-M/DS1-M to the current CMSG/DMSG/EMSG switches. If you need to adjust force capacity, stepping down to the 20mm bore yields 157N push at 0.5 MPa, while stepping up to the 32mm bore provides 402N push at 0.5 MPa.
At 145mm of travel, side-load bending risks increase on the 10mm rod, so keeping the U flat-end mounting rigid is crucial to prevent drift. The MAL relies on a fixed rubber bumper, not an adjustable cushion; if your application now requires end-of-stroke deceleration, specify the MBLC variant on the current line. Remember that a plain MAL or MBL does not hold its load when air pressure drops; the rod will drift, so utilize an external rod lock or pilot-operated check valve for fail-safe holding.
Upgrade checklist
- ✓ Order the MBL25X145SU (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 MBL25X145SU instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X145SU FAQ
Yes, the AirTAC MAL25X145SU is discontinued. The exact drop-in replacement is the MBL25X145SU, which maintains the same 25mm bore, 145mm stroke, 245N push force, G1/8 port, and U flat-end mounting.
At 0.5 MPa, the push force is 245N and the pull force is 206N. At 0.7 MPa, the push force is 343N, with a maximum theoretical force of 50 kgf at 1.0 MPa. The -S magnet on this MAL works with CS1-M/DS1-M switches, but the MBL replacement uses CMSG/DMSG/EMSG sensors.
