This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X300-S-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X300-S-U 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 MAL25X300-S-U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X300-S-U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 300mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X300-S-U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X300-S-U
The AirTAC MAL25X300-S-U is a discontinued double-acting aluminum mini round cylinder. It delivers 245 N of push force and 206 N of pull force at 0.5 MPa from a 25 mm bore. The exact drop-in replacement is the MBL25X300-S-U, which matches the 300 mm stroke, G1/8 port, M10x1.25 rod thread, and U flat-end rear cover. You can install the MBL without altering your existing mounting layout.
This legacy unit features a built-in -S magnet for position sensing. On the original MAL body, which uses threaded front and back covers, this magnet pairs with the older CS1-M and DS1-M reed switches. When you transition to the riveted rolling-packed body of the MBL25X300-S-U, you must upgrade to the current CMSG, DMSG, or EMSG sensor family. The piston relies on a heterogeneous two-way seal that retains lubricant, while the carbon-steel rod is protected by a 20 um hard chrome plating to resist wear.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X300-S-U 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 MBL25X300-S-U 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 MAL25X300-S-U Is Used
Pouch Packaging Diverter
Pushes filled retort pouches from a continuous belt into a secondary sealing lane using 245 N of thrust over the 300 mm travel distance.
PCB Board Ejection Station
Extends 300 mm to lift populated printed circuit boards out of a testing fixture, relying on the -S magnet to trigger the CS1-M reed switch for safe extraction timing.
Small Parts Tray Indexer
Advances plastic component trays along a rigid U flat-end mounting axis, using the 343 N push force at 0.7 MPa to overcome sliding friction.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X300-S-U with MBL25X300-S-U
To replace the MAL25X300-S-U, order the MBL25X300-S-U. Confirm your 25 mm bore, 300 mm stroke, PT tapered port thread, U flat-end back cover, and the -S magnet requirement before ordering. If your application needs less force, stepping down to a 20 mm bore yields 157 N of push at 0.5 MPa. If you need more power, stepping up to a 32 mm bore provides 402 N at 0.5 MPa. Because the 300 mm stroke amplifies the risk of rod bending on the 10 mm rod, use an external guide rail to absorb lateral stress.
The MAL relies on a fixed rubber bumper, so it cannot absorb heavy kinetic energy at stroke ends; if your load requires end-deceleration, step up to the current MBLC series for an adjustable air cushion. A plain cylinder does not hold its position when air pressure drops, so install a pilot-operated check valve if drifting poses a hazard.
Upgrade checklist
- ✓ Order the MBL25X300-S-U (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 MBL25X300-S-U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X300-S-U FAQ
Yes, the MAL25X300-S-U is discontinued. The exact drop-in replacement is the MBL25X300-S-U, which provides identical bore, stroke, output force, G1/8 port, and U flat-end back cover. You must upgrade your sensors, as the older CS1-M and DS1-M switches used on the MAL are replaced by CMSG, DMSG, or EMSG switches on the MBL.
At 0.5 MPa the push force is 245 N and the pull force is 206 N. At 0.7 MPa the push force is 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa. Operating pressure ranges from 0.1 to 1.0 MPa, speed is 30-800 mm/s, and it uses a fixed rubber bumper rather than an adjustable cushion.
