This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X45U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X45U 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 MAL25X45U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X45U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 45mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X45U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X45U
The AirTAC MAL25X45U is a discontinued compact double-acting aluminum mini round cylinder with a 25mm bore and 45mm stroke. It delivers a 245N push and 206N pull force at 0.5 MPa, utilizing a Ø10mm carbon-steel rod with 20µm hard-chrome plating. Because this end-of-life unit is no longer manufactured, AirTAC provides the exact drop-in replacement: the MBL25X45U, which matches the original bore, stroke, output force, G1/8 port, and flat-end U back cover for a seamless swap.
This specific SKU lacks the -S magnet option, meaning it cannot support a position sensor and relies entirely on mechanical end-of-stroke timing. The legacy MAL features threaded front and back covers, whereas the current MBL replacement utilizes a riveted rolling-packed body. Both generations share a fixed rubber bumper for end-of-stroke deceleration, but if your application requires adjustable air cushioning, you must step up to the MBLC variant on the current line.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X45U Technical Specifications

| Bore size | Ø25 mm |
| Stroke | 45 mm |
| Acting type | Double acting |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.1 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Fixed rubber bumper |
| Max standard stroke | Up to 500 mm |
Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X45U 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 MBL25X45U 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 MAL25X45U Is Used
PCB Degating Station
Provides 245N of push force at 0.5 MPa to cleanly snap small plastic gates off populated circuit boards without damaging delicate traces.
Carton Flap Folder
Uses the 45mm stroke to tuck inner flaps on small pharmaceutical cartons just before the sealing head applies tape.
Connector Insertion Jig
Drives a 10mm rod to press modular wire harness connectors into PCB headers with precise 206N of pull force retraction.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X45U with MBL25X45U
To replace the MAL25X45U, order the MBL25X45U. Verify your existing setup uses the default PT tapered port thread and the rigid flat-end U back cover before installing. If you need to size down for a lighter task, the 20mm bore neighbor provides 157N of push force at 0.5 MPa. Conversely, stepping up to the 32mm bore yields 402N of push force for heavier loads. Keep in mind that a plain double-acting cylinder does not hold its position if air pressure drops; the rubber bumper only softens the stroke impact and will not lock the rod. If adjustable cushioning is required rather than a fixed bumper, select the MBLC series.
Upgrade checklist
- ✓ Order the MBL25X45U (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 MBL25X45U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X45U FAQ
Yes, the MAL25X45U is discontinued. The exact drop-in replacement is the AirTAC MBL25X45U, which matches the 25mm bore, 45mm stroke, 245N push force, G1/8 port, and flat-end U back cover.
At 0.5 MPa, it delivers 245N push and 206N pull; at 0.7 MPa it delivers 343N push, with a theoretical maximum of 50 kgf at 1.0 MPa. This specific SKU has no -S magnet, so it cannot accept a CS1-M or DS1-M position sensor.
