This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X900-S-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X900-S-U 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 MAL25X900-S-U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X900-S-U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 900mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X900-S-U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X900-S-U
The AirTAC MAL25X900-S-U is a discontinued double-acting aluminum mini round cylinder with a 25mm bore and 900mm stroke. Because 900mm exceeds the 500mm standard maximum, this unit was a made-to-order configuration. It delivers 245N push and 206N pull at 0.5MPa, scaling to a 50kgf maximum at 1.0MPa. AirTAC replaced this legacy unit with the MBL25X900-S-U, a true drop-in upgrade retaining the exact 25mm bore, 900mm stroke, G1/8 port, U flat-end back cover, and magnetic piston.
This SKU features a -S magnet for position sensing. On the original MAL body—which uses threaded front and back covers—the magnet pairs with older CS1-M or DS1-M switches. The modern MBL replacement switches to a riveted rolling-packed body and requires current CMSG, DMSG, or EMSG sensors. The MAL relies on a fixed rubber bumper, so if your 900mm stroke generates excessive end-of-stroke kinetic energy, consider the MBLC variant on the current line for an adjustable air cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X900-S-U 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 MBL25X900-S-U 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 MAL25X900-S-U Is Used
Long-Reach Transfer Arm
Pushes lightweight cardboard cartons across a 900mm gap between packaging conveyors, utilizing the 245N push force at 0.5MPa to overcome guide friction.
Textile Beam Indexer
Shifts a yarn-guide carriage along a 900mm track in a textile winding machine, where the compact 25mm bore fits tight side-frame clearances.
Vertical Parts Elevator
Raises a small plastic parts tote by 900mm in an assembly cell, requiring an external guide rail to support the load and prevent rod bending.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X900-S-U with MBL25X900-S-U
To replace this MAL, order the MBL25X900-S-U. Confirm your 25mm bore, 900mm made-to-order stroke, PT tapered port thread, U flat-end rigid back cover, and -S magnet. Because the -S magnet is present, you must upgrade your sensors: the old CS1-M / DS1-M switches will not fit the MBL body, so select CMSG, DMSG, or EMSG switches instead. If your application needs end-of-stroke deceleration rather than a fixed rubber bumper, step up to the MBLC for an adjustable air cushion.
For sizing flexibility, stepping down to the 20mm bore yields 157N push at 0.5MPa, while stepping up to the 32mm bore provides 402N push at 0.5MPa. A 900mm stroke on a 10mm rod creates a severe side-load and rod-bending risk; you must use an external guide rail or a pivot mount rather than relying on the cylinder itself. Finally, this cylinder does not hold its load if air pressure drops—the rod will drift—so install an external rod lock or pilot-operated check valve for safety.
Upgrade checklist
- ✓ Order the MBL25X900-S-U (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 MBL25X900-S-U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X900-S-U FAQ
Yes, the MAL25X900-S-U is discontinued. The exact drop-in replacement is the MBL25X900-S-U. It offers identical bore, stroke, output force, G1/8 port, and U flat-end mounting. You simply order the MBL model for a direct swap, though you must update your sensors to CMSG, DMSG, or EMSG switches.
The 25mm bore provides 245N push and 206N pull at 0.5MPa, 343N push at 0.7MPa, and a maximum theoretical force of 50kgf at 1.0MPa. The port size is G1/8, the rod is 10mm with an M10x1.25 rod-end thread, and the 900mm stroke is a non-standard made-to-order length.
