This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X400-S-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X400-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 MAL25X400-S-U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X400-S-U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 400mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X400-S-U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X400-S-U
The AirTAC MAL25X400-S-U is a discontinued double-acting aluminum mini round cylinder with a 25mm bore and 400mm stroke. It delivers 245N of push force and 206N of pull force at 0.5 MPa. The exact drop-in replacement is the MBL25X400-S-U, which matches the bore, stroke, output force, G1/8 port, and U flat-end back cover. You can order the MBL25X400-S-U directly to keep your machine running.
This legacy unit features a U flat-end back cover for rigid rear mounting and a built-in magnet (-S) for position detection. The MAL body uses threaded front and back covers, whereas the current MBL replacement utilizes a riveted rolling-packed body for the same physical footprint. Additionally, the -S magnet on this MAL works with older CS1-M and DS1-M reed switches; upgrading to the MBL25X400-S-U means you must switch to the modern CMSG, DMSG, or EMSG sensor family.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X400-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 MBL25X400-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 MAL25X400-S-U Is Used
PCB Shuttle Routing
Drives a 400mm stroke shuttle carriage that transfers bare PCBs between SMT pick-and-place machines, utilizing the 245N push force to overcome guide friction.
Carton Flap Folder
Actuates a 400mm sweeping arm to fold minor flaps on packaging lines, where the U flat-end cover rigidly anchors the cylinder body against repetitive lateral sweeping.
Textile Beam Indexing
Shifts a yarn beam 400mm laterally into the loom weaving position, relying on the -S magnet to trigger a CS1-M reed switch for precise home detection.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X400-S-U with MBL25X400-S-U
To replace the MAL25X400-S-U, order the MBL25X400-S-U. Confirm your 10mm rod-end thread (M10x1.25) and default PT porting match your existing fittings. The U flat-end back cover provides a rigid rear mount, so ensure your mounting surface is square. If you need to adjust speed or step sizes, the next bore down is 20mm (157N push at 0.5 MPa) and the next size up is 32mm (402N push at 0.5 MPa). Because this is a 400mm stroke on a 10mm rod, side-load tolerance is very low; you must use an external guide rail to prevent rod bending. Note that the fixed rubber bumper softens end-of-stroke impact but does not lock the rod—air loss means the load drifts. If you need an adjustable air cushion, specify the MBLC series instead of the standard MBL.
Upgrade checklist
- ✓ Order the MBL25X400-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 MBL25X400-S-U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X400-S-U FAQ
Yes, the MAL25X400-S-U is discontinued. The exact drop-in replacement is the MBL25X400-S-U, which matches the 25mm bore, 400mm stroke, 245N force, G1/8 port, and U flat-end cover. Note that the -S magnet on the MBL works with CMSG, DMSG, or EMSG switches, not the older CS1-M or DS1-M sensors.
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.
