This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X425U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X425U 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 MAL25X425U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X425U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 425mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X425U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X425U
The AirTAC MAL25X425U is a discontinued double-acting aluminum mini round cylinder with a 25mm bore and 425mm stroke, delivering 245N of push force at 0.5MPa. The exact drop-in replacement is the MBL25X425U, matching the original force, G1/8 port, and U flat-end rear cover. This legacy model features a threaded front and back cover assembly, whereas the current MBL utilizes a riveted rolling-packed body for equally robust performance.
Because this specific SKU lacks the -S magnet option, it cannot accept a position sensor. The internal mechanics rely on a heterogeneous two-way seal that retains grease, paired with a self-lubricating front-cover bearing guide to support the Ø10mm carbon-steel rod. End-of-stroke deceleration is handled strictly by a fixed rubber bumper, as the legacy line predates the adjustable air-cushion technology found in the modern MBLC series.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X425U 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 MBL25X425U 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 MAL25X425U Is Used
PCB Conveyor Divert
Pushes routing gates on a printed circuit board conveyor using 245N of thrust, fitting into tight 25mm bore machinery envelopes.
Carton Flap Folder
Actuates a 425mm stroke folding arm on a packaging line, relying on the rigid U flat-end cover to maintain alignment during rapid retraction.
Textile Loom Tensioner
Shifts a yarn tensioning jig back and forth across a 425mm span, where the fixed rubber bumper absorbs the repetitive end-of-stroke impact.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X425U with MBL25X425U
To replace the MAL25X425U, order the MBL25X425U. Confirm your 425mm stroke requirement, the default PT tapered port thread, and the rigid U flat-end back cover. If your machine requires end-of-stroke sensing, note that this non-magnet SKU cannot support a sensor; you must specify an -S magnet on the MBL and migrate from the legacy CS1-M/DS1-M switches to the current CMSG/DMSG/EMSG family.
Verify your force needs: the 25mm bore yields 245N push and 206N pull at 0.5MPa. If you need less force, step down to the 20mm bore (157N push), or step up to the 32mm bore (402N push) for heavier loads. Since the 425mm stroke exceeds 300mm, the small Ø10mm rod has low side-load tolerance; use an external guide rail to prevent rod bending. A plain bumper does not hold position if air pressure drops, so add an external rod lock for vertical loads. If you need adjustable cushioning, upgrade to the MBLC.
Upgrade checklist
- ✓ Order the MBL25X425U (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 MBL25X425U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X425U FAQ
Yes, the MAL25X425U is discontinued. The exact drop-in replacement is the MBL25X425U, offering the same 25mm bore, 425mm stroke, G1/8 port, and U flat-end mounting. You will retain the same force and footprint, though the MBL uses a riveted rolling-packed body instead of threaded covers.
At 0.5MPa it provides 245N push and 206N pull; at 0.7MPa push is 343N, with a theoretical maximum of 50kgf at 1.0MPa. The fixed rubber bumper only softens end-of-stroke impact and is not a lock; the rod will drift if air pressure is lost, so use an external rod lock for vertical loads.
