This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X25UH — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X25UH 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 MAL25X25UH
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X25UH is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 25mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X25UH, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X25UH
The AirTAC MAL25X25UH is a discontinued compact double-acting aluminum mini round cylinder. Designed for tight spaces, it delivers a 245 N push and 206 N pull force at 0.5 MPa, utilizing a 10 mm carbon-steel rod with a 20 um hard-chrome plating. The direct drop-in replacement is the MBL25X25UH, matching the 25 mm bore, 25 mm stroke, G1/8 port, and flat-end rear cover exactly.
This legacy model features a fixed rubber bumper for end-of-stroke deceleration and a heterogeneous two-way seal that retains grease. The original MAL body uses threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed body. Because this specific SKU lacks an -S magnet, it cannot accommodate a position sensor.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X25UH 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 MBL25X25UH 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 MAL25X25UH Is Used
PCB Drill Chuck Actuation
Provides 245 N of push force at 0.5 MPa to drive small pneumatic drill chucks in electronics fabrication, fitting easily into compact routing machinery.
Packaging Flap Folder
Uses its 25 mm stroke and 206 N pull force to tuck cardboard flaps on high-speed packaging lines, where the U flat-end cover mounts rigidly to the frame.
Connector Insertion Jig
Cycles at 30-800 mm/s to press micro-connectors into PCBs, relying on the self-lubricating front-cover bearing guide to maintain precise vertical alignment.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X25UH with MBL25X25UH
To replace the MAL25X25UH, order the MBL25X25UH. Verify your 25 mm bore, 25 mm stroke, G1/8 port, and the U flat-end back cover. This SKU uses a default PT tapered port thread and includes no magnet, meaning position sensing is not supported. If you ever need sensing, you must switch to an -S variant and update your sensors, as the legacy CS1-M / DS1-M switches are replaced by CMSG / DMSG / EMSG switches on the MBL line.
For sizing, this 245 N push force at 0.5 MPa sits between the 20 mm bore (157 N) and the 32 mm bore (402 N). If you need less force in a tighter footprint, step down to the 20 mm; if driving heavier slides, step up to the 32 mm. Note that the fixed rubber bumper is not an adjustable cushion; for adjustable air cushioning, look to the MBLC variant on the current line. Furthermore, this cylinder will drift and cannot hold a load if air pressure is lost, requiring an external rod lock for fail-safe holding.
Upgrade checklist
- ✓ Order the MBL25X25UH (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 MBL25X25UH instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X25UH FAQ
Yes, the MAL25X25UH is discontinued. The exact drop-in replacement is the MBL25X25UH, offering the same 25 mm bore, 25 mm stroke, 245 N push force, G1/8 port, and U flat-end mounting.
At 0.5 MPa, it provides 245 N push and 206 N pull; at 0.7 MPa, push is 343 N, with a maximum theoretical force of 50 kgf at 1.0 MPa. Because this SKU lacks an -S magnet, it cannot accept position sensors like the CS1-M or DS1-M.
