This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X250SUFA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X250SUFA 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 MAL25X250SUFA
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X250SUFA is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 250mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X250SUFA, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X250SUFA
The AirTAC MAL25X250SUFA is a discontinued double-acting aluminum mini round cylinder with a 25mm bore and 250mm 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. Because this series has reached end-of-life, you should order the exact drop-in replacement: the MBL25X250SUFA. It matches the bore, stroke, output force, port size, and FA flange mounting perfectly.
This legacy unit features a U flat-end back cover for rigid rear mounting and an FA flange for front attachment. The original MAL body uses threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed body. Your -S magnet configuration works with older CS1-M or DS1-M switches on this cylinder, but upgrading to the MBL means transitioning to current CMSG, DMSG, or EMSG sensors. The internal piston relies on a heterogeneous two-way seal that retains grease, while the carbon-steel rod has 20 um hard-chrome plating to resist wear.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X250SUFA 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 MBL25X250SUFA 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 MAL25X250SUFA Is Used
PCB Edge Conveyor Gating
Actuates a routing diverter on an SMT line, using the 245N push force at 0.5 MPa to deflect populated boards without damaging edge connectors.
Carton Flap Folder
Folds the minor flaps of small pharmaceutical cartons on a continuous motion packaging machine, fitting easily into tight transfer spaces.
Lathe Tailstock Ejector
Pushes small brass bushings out of a collet chuck, using the 250mm stroke to clear the spindle bore entirely before robotic retrieval.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X250SUFA with MBL25X250SUFA
To replace the MAL25X250SUFA, order the MBL25X250SUFA, ensuring your 25mm bore, 250mm stroke, G1/8 port, FA flange, and U flat-end back cover specifications match. If you need to step down to a smaller bore for a lighter task, the 20mm neighbor provides 157N push at 0.5 MPa. If you need more force, stepping up to the 32mm bore yields 402N push at 0.5 MPa. Keep in mind that a plain MBL does not hold a load when air pressure drops; the rod drifts, so you must add an external rod lock or pilot-operated check valve for fail-safe positioning. If your application requires end-of-stroke deceleration, note that the MAL uses a fixed rubber bumper, and the modern drop-in equivalent with an adjustable air cushion is the MBLC25X250SUFA.
Because the stroke is 250mm and the rod diameter is only 10mm, side-load tolerance is low. For an extension of this length, you should use an external guide rail to prevent rod bending, or pivot the U back cover to absorb arcing loads.
Upgrade checklist
- ✓ Order the MBL25X250SUFA (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 MBL25X250SUFA instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X250SUFA FAQ
Yes, the MAL25X250SUFA is discontinued. The exact drop-in replacement is the MBL25X250SUFA, offering the same 25mm bore, 250mm stroke, FA flange, and G1/8 port. The -S magnet on the old MAL works with CS1-M and DS1-M switches, but the MBL replacement requires CMSG, DMSG, or EMSG sensors.
The 25mm bore provides 245N of push force and 206N of pull force at 0.5 MPa. At 0.7 MPa, the push force is 343N. The maximum theoretical force is 50 kgf at 1.0 MPa. It operates at 0.1-1.0 MPa with a speed range of 30-800 mm/s.
