This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X125-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X125-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 MAL25X125-U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X125-U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 125mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X125-U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X125-U
The AirTAC MAL25X125-U is a discontinued compact double-acting aluminum mini round cylinder with a 25mm bore and 125mm stroke. It delivers 245N push and 206N pull at 0.5 MPa, utilizing a U flat-end back cover for rigid mounting. AirTAC ended this series, replacing it with the drop-in MBL25X125-U, which matches the exact bore, stroke, output force, G1/8 port, and mounting footprint.
This legacy SKU lacks an -S magnet, meaning it cannot accept a position sensor. The original MAL body uses threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed body for structural rigidity. Both designs share a fixed rubber bumper for end-of-stroke deceleration and a carbon-steel rod with 20µm hard chrome plating to resist wear.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X125-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 MBL25X125-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 MAL25X125-U Is Used
PCB Router Z-Axis Gate
Actuates a safety gate on a PCB depaneling router, using the 245N push force at 0.5 MPa to ensure positive lockout during bit changes.
Semiconductor Wafer Diverter
Shifts a small pneumatic diverter flap inside a tight electronics test fixture, relying on the U flat-end cover for rigid, zero-play alignment.
Carton Labeling Stop
Extends 125mm to pop up a mechanical stop for small product cartons at a labeling station, retracting below the conveyor belt when idle.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X125-U with MBL25X125-U
To replace the MAL25X125-U, order the MBL25X125-U. Verify your setup uses the default PT tapered port thread and the U flat-end rear cover for rigid alignment. Because this SKU lacks a magnet, no sensor is required; if you later need position detection, the MBL family uses CMSG, DMSG, or EMSG switches. If your load requires a softer stop than the fixed rubber bumper, step up to the MBLC variant which adds an adjustable air cushion.
For sizing flexibility, stepping down to the 20mm bore yields 157N push force at 0.5 MPa, while stepping up to the 32mm bore provides 402N. Note that this plain 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 for fail-safe holding. At 125mm stroke, the 10mm rod handles moderate extension well, but for longer reaches always support the load externally to prevent rod bending.
Upgrade checklist
- ✓ Order the MBL25X125-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 MBL25X125-U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X125-U FAQ
Yes, the MAL25X125-U is discontinued. The exact drop-in replacement is the MBL25X125-U, which offers the same 25mm bore, 125mm stroke, 245N force, G1/8 port, and U flat-end mounting.
At 0.5 MPa it provides 245N push and 206N pull; at 0.7 MPa it provides 343N push, with a theoretical maximum of 50 kgf at 1.0 MPa. This specific SKU lacks a magnet and cannot accept a sensor; if sensing is needed, an MBL with an -S magnet uses CMSG, DMSG, or EMSG switches.
