This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X185U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X185U 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 MAL25X185U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X185U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 185mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X185U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X185U
The AirTAC MAL25X185U is a discontinued double-acting aluminum mini round cylinder with a 25mm bore and 185mm stroke. It delivers 245N of push force and 206N of pull force at 0.5 MPa, utilizing a Ø10mm carbon-steel rod with 20µm hard chrome plating. Because this end-of-life model has a U flat-end back cover, it mounts rigidly to flat surfaces rather than allowing articulation.
AirTAC replaced the MAL series with the MBL aluminum-barrel line. The exact drop-in replacement is the MBL25X185U, which matches the original bore, stroke, output force, G1/8 port, and mounting footprint. The legacy MAL uses threaded front and back covers on the barrel, whereas the current MBL features a riveted rolling-packed body. Furthermore, this specific SKU lacks an -S magnet, meaning it cannot accept a position sensor and requires mechanical end-of-stroke detection.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X185U 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 MBL25X185U 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 MAL25X185U Is Used
PCB Shuttle Ejection
Pushes populated printed circuit boards out of a testing bay using 245N of force, where the 185mm stroke fully clears the conveyor frame.
Carton Flap Folder
Folds small packaging flaps on a continuous flow wrapper, relying on the rigid U-mount to maintain square alignment against the cardboard.
Small Parts Sorter
Diverts metal stampings into reject chutes, utilizing the self-lubricating front-cover bearing to maintain smooth actuation over rapid cycles.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X185U with MBL25X185U
To replace the MAL25X185U, order the MBL25X185U and reuse your existing G1/8 pneumatic fittings and PT threaded ports. The U flat-end back cover provides rigid rear mounting, which is ideal for fixed brackets but will not tolerate misalignment. If your application requires position sensing, note that this original SKU has no magnet; you must upgrade to an MBL25X185US to use modern CMSG, DMSG, or EMSG switches (the older CS1-M/DS1-M sensors are obsolete).
For sizing flexibility, stepping down to the 20mm bore yields 157N of push force at 0.5 MPa, while stepping up to the 32mm bore provides 402N. Since the 185mm stroke exceeds 300mm, the small 10mm rod is highly susceptible to bending under side loads; you must use an external guide rail or ensure strictly linear motion. The MAL relies on a fixed rubber bumper, so if you need adjustable end-cushioning to prevent harsh impacts, specify the MBLC variant. Note that a plain cylinder cannot hold a load if air pressure drops.
Upgrade checklist
- ✓ Order the MBL25X185U (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 MBL25X185U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X185U FAQ
Yes, the MAL25X185U is discontinued. The exact drop-in replacement is the MBL25X185U, which matches the 25mm bore, 185mm stroke, G1/8 port, and U flat-end mounting. The new MBL uses a riveted body instead of threaded covers, but the performance and dimensions are identical.
At 0.5 MPa, the push force is 245N and the pull force is 206N. At 0.7 MPa, the push force is 343N, with a maximum theoretical force of 50 kgf at 1.0 MPa. This specific SKU has no -S magnet, so it cannot accept a position sensor.
