This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X50SUH — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X50SUH 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 MAL25X50SUH
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X50SUH is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 50mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X50SUH, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X50SUH
The AirTAC MAL25X50SUH is a discontinued double-acting aluminum mini round cylinder with a 25mm bore and 50mm stroke. It delivers 245N of push force and 206N of pull force at 0.5 MPa. Because this MAL series is end-of-life, AirTAC replaced it with the MBL25X50SUH, a drop-in upgrade retaining the exact bore, stroke, force, G1/8 port, and U flat-end rear cover.
This SKU includes a built-in magnet (-S) for position sensing. The legacy MAL works with older CS1-M and DS1-M switches, but the MBL replacement requires the current CMSG, DMSG, or EMSG sensor families. The original MAL body used threaded front and back covers, whereas the modern MBL features a riveted rolling-packed body for the same ratings. The 10mm carbon-steel rod has a 20 um hard chrome plating, and the piston relies on a heterogeneous two-way seal that retains grease for long service life.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X50SUH 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 MBL25X50SUH 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 MAL25X50SUH Is Used
PCB Router Gantry
Cycles a light 245N push at 0.5 MPa to plunge a spindle on a PCB depaneling router, using the 50mm stroke to clear the fixture during tool changes.
Carton Flap Folder
Deploys the 10mm hard-chrome rod to tuck minor flaps on a small pharmaceutical cartoning machine, relying on the U flat-end cover for rigid frame mounting.
Tube Rack Ejector
Kicks 2ml sample tubes out of a centrifuge rack with a 206N pull force, using the -S magnet to trigger a reed sensor for cycle counting.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X50SUH with MBL25X50SUH
To replace the MAL25X50SUH, order the MBL25X50SUH. Confirm your 50mm stroke, G1/8 port, PT thread form, U flat-end back cover, and the -S magnet requirement. If your application needs an adjustable air cushion instead of the fixed rubber bumper found on the MAL, step up to the MBLC variant on the current line. If sizing down, the 20mm bore provides 157N push at 0.5 MPa; if sizing up, the 32mm bore yields 402N push at 0.5 MPa. A plain MAL or MBL cylinder will not hold a load if air pressure drops, as the bumper only softens end-of-stroke impacts rather than locking the rod, so add an external rod lock for vertical safety.
Upgrade checklist
- ✓ Order the MBL25X50SUH (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 MBL25X50SUH instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X50SUH FAQ
Yes, the MAL25X50SUH is discontinued. The exact drop-in replacement is the MBL25X50SUH, which matches the 25mm bore, 50mm stroke, 245N push force, G1/8 port, and U flat-end cover. Note that if you use the -S magnet, the MBL requires newer CMSG, DMSG, or EMSG switches instead of the older CS1-M or DS1-M sensors.
The 25mm bore uses a G1/8 port and a 10mm rod. At 0.5 MPa it provides 245N push and 206N pull. At 0.7 MPa the push force is 343N. The maximum theoretical force is 50 kgf at 1.0 MPa.
