This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X125-S-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X125-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 MAL25X125-S-U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X125-S-U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 125mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X125-S-U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X125-S-U
The AirTAC MAL25X125-S-U is a discontinued compact double-acting aluminum mini round cylinder. Delivering 245 N of push force and 206 N of pull force at 0.5 MPa, it operates on a 25 mm bore with a 125 mm stroke. The exact drop-in replacement is the MBL25X125-S-U, which matches the original bore, stroke, output force, G1/8 port, and flat-end mounting footprint.
This legacy SKU includes a built-in magnet (-S) for position sensing and a U-type flat-end back cover for rigid rear mounting. During the upgrade, AirTAC changed the body construction from the MAL's threaded front and back covers to a riveted rolling-packed body on the MBL. Furthermore, the older CS1-M and DS1-M reed switches used on this MAL are superseded by the current CMSG, DMSG, or EMSG sensor families on the MBL replacement. The piston relies on a heterogeneous two-way seal that retains grease, while the carbon-steel rod features 20 um hard-chrome plating for wear resistance.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X125-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 MBL25X125-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 MAL25X125-S-U Is Used
PCB Edge Belt Routing
Actuates a 245 N diverter arm at 0.5 MPa to route bare circuit boards between inspection lanes without crushing the delicate components.
Carton Label Applicator
Pushes a 125 mm stroke tamp pad to press shipping labels onto small packaging, using the rigid U flat-end mount to absorb repeated impact.
Connector Insertion Press
Provides 206 N of pull force at 0.5 MPa to retract an insertion head after seating electronic connectors, relying on the -S magnet to verify retraction.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X125-S-U with MBL25X125-S-U
To replace the MAL25X125-S-U, order the exact drop-in MBL25X125-S-U. Confirm the 25 mm bore, 125 mm stroke, G1/8 port, and PT thread form are correct for your plumbing. Because this SKU features the -S magnet, you must update your sensing setup: the legacy CS1-M and DS1-M switches will not fit the new body, so migrate to the CMSG, DMSG, or EMSG sensor families. The U-type flat-end back cover provides rigid rear mounting, which is ideal for fixed-bracket setups rather than arcing pivot loads.
For sizing flexibility, stepping down to the 20 mm bore yields 157 N of push force at 0.5 MPa, while stepping up to the 32 mm bore provides 402 N. Remember that the fixed rubber bumper only softens the end of stroke and does not hold the load if air pressure drops; for position holding, install an external rod lock or pilot-operated check valve. If your application requires adjustable cushioning to prevent end-of-stroke slamming, the MAL cannot provide it—you must upgrade to the MBLC variant on the current line. At 125 mm, side-load tolerance is moderate, but the 10 mm rod is highly susceptible to bending if misaligned, so ensure strict parallelism with your guide rails.
Upgrade checklist
- ✓ Order the MBL25X125-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 MBL25X125-S-U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X125-S-U FAQ
Yes, the MAL series is end-of-life. The exact drop-in replacement is the MBL25X125-S-U, which matches the 25 mm bore, 125 mm stroke, G1/8 port, and U-type flat-end mounting. You must update your sensors because the MBL requires CMSG, DMSG, or EMSG switches instead of the older CS1-M or DS1-M models.
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. The cylinder operates at 0.1-1.0 MPa with a speed range of 30-800 mm/s.
