This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X650U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X650U 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 MAL25X650U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X650U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 650mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X650U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X650U
The AirTAC MAL25X650U is a discontinued double-acting aluminum mini round cylinder engineered for compact spaces. Delivering 245 N of push force at 0.5 MPa, this non-standard 650 mm stroke unit was made to order, exceeding the 500 mm standard limit. AirTAC replaced this legacy series with the MBL25X650U, a drop-in alternative retaining the exact bore, stroke, force, G1/8 port, and U flat-end rear cover.
This SKU lacks a built-in magnet, meaning it cannot accept position sensors. The original MAL body used threaded front and back covers, whereas the current MBL replacement features a riveted rolling-packed body. Both designs utilize a heterogeneous two-way grease-retaining seal and a self-lubricating front-cover bearing guide to support the Ø10 mm carbon-steel rod, which is plated with 20 µm hard chrome for wear resistance.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X650U 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 MBL25X650U 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 MAL25X650U Is Used
PCB Conveyor Diverter
Pushes lightweight populated PCB panels across a 650 mm transfer gap at 245 N push force, utilizing the compact 25 mm bore to fit within tight electronics assembly machinery.
Carton Flap Folder
Actuates a folding mechanism for small packaging cartons over a long 650 mm travel, relying on the U flat-end rigid back cover to maintain strict alignment without pivot arcing.
Lab Automation Transfer
Extends a gripper to move assay trays between testing stations, requiring the full 650 mm stroke while benefiting from the grease-retaining two-way seal for clean operation.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X650U with MBL25X650U
To replace the MAL25X650U, order the MBL25X650U, ensuring you match the PT tapered thread and U flat-end back cover. If your application requires end-of-stroke sensing, note that this specific SKU has no magnet. You would need to specify an MBL25X650US instead, which shifts you from the legacy CS1-M / DS1-M switches to the modern CMSG / DMSG / EMSG sensor family. If a cushion is needed to absorb kinetic energy at the ends of this long stroke, the fixed rubber bumper on the MAL is insufficient; step up to the current MBLC line for an adjustable air cushion.
At 650 mm, the 10 mm rod is highly susceptible to bending under side loads; an external guide rail is mandatory to prevent premature seal failure. If you need less force, the neighboring 20 mm bore provides 157 N of push at 0.5 MPa. If your load requires more force, the 32 mm bore yields 402 N at 0.5 MPa. Remember, a plain cylinder does not hold a load when air pressure drops; the bumper only softens the impact, so add an external rod lock for vertical holding.
Upgrade checklist
- ✓ Order the MBL25X650U (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 MBL25X650U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X650U FAQ
Yes, the MAL25X650U is discontinued. The exact drop-in replacement is the MBL25X650U, which matches the 25 mm bore, 650 mm stroke, 245 N push force at 0.5 MPa, G1/8 port, and U flat-end mounting. The MBL upgrades the body from threaded covers to a riveted rolling-packed design.
At 0.5 MPa, it pushes 245 N and pulls 206 N; at 0.7 MPa it pushes 343 N, with a maximum theoretical force of 50 kgf at 1.0 MPa. Because this specific SKU lacks the -S magnet, it cannot accept CS1-M or DS1-M position sensors; sensing requires upgrading to an MBL25X650US and using CMSG/DMSG/EMSG switches.
