This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X50-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X50-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 MAL25X50-U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X50-U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 50mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X50-U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X50-U
The AirTAC MAL25X50-U is a discontinued compact double-acting aluminum mini round cylinder with a 25mm bore and 50mm stroke. It delivers 245N of push force and 206N of pull force at 0.5MPa. Featuring a U flat-end back cover for rigid mounting, this legacy unit has been superseded by the drop-in MBL25X50-U replacement, which matches the exact bore, stroke, output force, G1/8 port, and mounting footprint.
Because this specific SKU lacks the -S magnet option, it cannot accommodate a position sensor. The original MAL design utilizes threaded front and back covers on the barrel, whereas the current MBL upgrade features a riveted rolling-packed body construction. Both versions rely on a fixed rubber bumper for end-of-stroke deceleration rather than an adjustable air cushion, which is only found on the MBLC variant. The piston employs a heterogeneous two-way seal that retains grease, and the 10mm carbon-steel rod features 20µm hard-chrome plating for wear resistance.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X50-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 MBL25X50-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 MAL25X50-U Is Used
PCB Depaneling Router
Provides 245N of push force at 0.5MPa to actuate the cutting blade carriage in tight electronics assembly cells.
IC Test Handler Ejection
Cycles rapidly at 30-800mm/s to eject tested integrated circuits from sockets using the rigid U flat-end back cover.
Package Diverter Gate
Uses the 50mm stroke to push small parcels onto a sorting branch, relying on the 10mm hard-chrome plated rod.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X50-U with MBL25X50-U
To replace the discontinued MAL25X50-U, order the MBL25X50-U, ensuring you retain the default PT tapered port thread, the U flat-end back cover, and the double-acting single-rod configuration. Since this SKU has no -S magnet, no sensor is required; if you ever need position detection, you must specify an MBL25X50S-U and migrate to the modern CMSG, DMSG, or EMSG switch family, as the older CS1-M and DS1-M sensors are incompatible with the new line. If you need to step up force, the neighboring 32mm bore provides 402N of push at 0.5MPa; stepping down to the 20mm bore yields 157N. Note that a plain MBL does not hold its load when air pressure is lost, as the rod will drift. If your application requires adjustable end-cushioning rather than a fixed rubber bumper, specify the MBLC25X50-U model instead.
Upgrade checklist
- ✓ Order the MBL25X50-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 MBL25X50-U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X50-U FAQ
Yes, the MAL25X50-U is discontinued. The exact drop-in replacement is the MBL25X50-U, which shares the identical 25mm bore, 50mm stroke, 245N push force, G1/8 port, and U flat-end mounting.
At 0.5MPa, the push force is 245N and pull is 206N; at 0.7MPa push is 343N, with a maximum theoretical force of 50kgf at 1.0MPa. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor.
