This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X6U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X6U 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 MAL25X6U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X6U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 6mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X6U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X6U
The AirTAC MAL25X6U is a discontinued double-acting aluminum mini round cylinder engineered for compact actuation. Delivering 245 N of push force at 0.5 MPa, this 25 mm bore unit features a 6 mm stroke and a U flat-end back cover. AirTAC replaced the legacy MAL line with the MBL series, making the MBL25X6U the exact drop-in replacement. It matches the original bore, stroke, output force, G1/8 port, and mounting interface perfectly.
This SKU lacks a built-in magnet, meaning it cannot support position sensing. The original MAL body uses threaded front and back covers, whereas the current MBL replacement features a riveted rolling-packed body for equally robust performance. Internally, a heterogeneous two-way seal retains grease, and the 10 mm carbon-steel rod features 20 um hard-chrome plating to resist wear. The cylinder relies on a fixed rubber bumper to soften end-of-stroke impacts rather than an adjustable cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X6U 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 MBL25X6U 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 MAL25X6U Is Used
PCB ejector pins
Provides a rapid 6 mm kick to pop delicate printed circuit boards out of testing fixtures without damaging traces.
Micro-clamp actuation
Delivers 245 N of push force at 0.5 MPa to secure small electronic housings during ultrasonic welding.
Carton flap diverter
Snaps a short 6 mm stop into position on a conveyor to gate small pharmaceutical cartons downstream.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X6U with MBL25X6U
To replace the MAL25X6U, order the MBL25X6U. Verify your 6 mm stroke, 25 mm bore, G1/8 port, and PT thread form. The U flat-end back cover provides rigid, straight-line mounting. Because this SKU has no -S magnet, it cannot accept a sensor; if you need position detection, you must switch to an MBL25X6US and update your switches, as the older CS1-M / DS1-M sensors are incompatible with the current CMSG / DMSG / EMSG family. If you need an adjustable air cushion instead of the standard rubber bumper, step up to the MBLC series.
For sizing flexibility, stepping down to a 20 mm bore drops the push force to 157 N at 0.5 MPa, while stepping up to a 32 mm bore increases it to 402 N. Note that a plain double-acting cylinder does not hold its load when air pressure is lost; the rod will drift. Use an external rod lock or pilot-operated check valve if the load must remain suspended.
Upgrade checklist
- ✓ Order the MBL25X6U (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 MBL25X6U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X6U FAQ
Yes, the MAL25X6U is discontinued. The exact drop-in replacement is the MBL25X6U, which offers the same 25 mm bore, 6 mm stroke, 245 N push force, G1/8 port, and U flat-end mounting. The main difference is the MBL uses a riveted rolling-packed body instead of threaded covers.
At 0.5 MPa, the push force is 245 N and the pull force is 206 N. At 0.7 MPa, the push force is 343 N, with a maximum theoretical force of 50 kgf at 1.0 MPa. Because this specific SKU lacks a -S magnet, it cannot support position sensors.
