This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X165U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X165U 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 MAL25X165U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X165U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 165mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X165U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X165U
The AirTAC MAL25X165U is a discontinued double-acting aluminum mini round cylinder with a 25 mm bore and 165 mm stroke. It delivers 245 N of push force and 206 N of pull force at 0.5 MPa, utilizing a G1/8 port and an M10x1.25 rod-end thread. AirTAC replaced this legacy unit with the MBL25X165U, a drop-in alternative that matches the exact bore, stroke, output force, port size, and U flat-end back cover. You can install the MBL replacement without altering your existing mounting layout.
This specific SKU lacks a built-in magnet, meaning it cannot support a position sensor. The original MAL body uses threaded front and back covers, whereas the newer MBL features a riveted rolling-packed body for structural rigidity. Inside, the piston relies on a heterogeneous two-way seal that retains grease, running alongside a self-lubricating front-cover bearing guide and a hard-chrome plated carbon-steel rod. End-of-stroke deceleration is handled by a fixed rubber bumper rather than an adjustable air cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X165U 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 MBL25X165U 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 MAL25X165U Is Used
PCB Conveyor Diverter
Pushes populated PCB panels sideways onto a secondary inspection track using 245 N of force at 0.5 MPa, fitting neatly within tight electronics assembly machinery.
Carton Flap Folder
Actuates a mechanical arm to tuck minor flaps on small packaging cartons, relying on the 165 mm stroke to clear the product path before retraction.
Textile Yarn Guide
Shifts a yarn threading guide across a knitting head, where the rigid U flat-end back cover ensures accurate alignment without rear pivot movement.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X165U with MBL25X165U
To replace the MAL25X165U, order the MBL25X165U. Verify your porting form, which is PT tapered by default, and ensure the U flat-end back cover suits your rigid rear mounting requirement. Because this model has no S designation, it cannot accommodate a sensor; if you need position detection, you must upgrade to an S-equipped MBL25X165US and switch from the legacy CS1-M or DS1-M switches to the current CMSG, DMSG, or EMSG sensor families. If your application requires adjustable end-cushioning to absorb kinetic energy, step up to the MBLC variant, as the MAL only offers a fixed rubber bumper.
For sizing flexibility, you can step down to a 20 mm bore cylinder for lighter loads, which provides 157 N of push force at 0.5 MPa, or step up to a 32 mm bore for heavier tasks, yielding 402 N at 0.5 MPa. At 165 mm of stroke, the 10 mm rod is susceptible to bending under lateral stress; use an external guide rail or a pivot mounting accessory to prevent side-load damage. Note that a plain cylinder does not hold its load when air pressure drops—the rod will drift.
Upgrade checklist
- ✓ Order the MBL25X165U (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 MBL25X165U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X165U FAQ
Yes, the MAL25X165U is discontinued. The exact drop-in replacement is the AirTAC MBL25X165U, which shares the identical 25 mm bore, 165 mm stroke, G1/8 port, and U flat-end mounting. The main structural change is that the MBL uses a riveted rolling-packed body instead of the older 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 increases to 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa. This specific SKU lacks a magnet, so it cannot accept CS1-M or DS1-M position sensors.
