This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X550-S-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X550-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 MAL25X550-S-U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X550-S-U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 550mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X550-S-U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X550-S-U
The AirTAC MAL25X550-S-U is a discontinued double-acting aluminum mini round cylinder with a 25mm bore and a 550mm made-to-order stroke. It delivers 245N push and 206N pull force at 0.5 MPa. The exact drop-in replacement is the MBL25X550-S-U, matching the bore, stroke, G1/8 port, and U flat-end back cover.
This legacy unit features a -S magnet for position sensing via older CS1-M / DS1-M switches, whereas the MBL replacement uses CMSG / DMSG / EMSG sensors. The original MAL body uses threaded front and back covers, while the upgraded MBL features a riveted rolling-packed body. Both share a fixed rubber bumper, so if adjustable end-of-stroke cushioning is needed, the MBLC variant should be specified instead.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X550-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 MBL25X550-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 MAL25X550-S-U Is Used
PCB Conveyor Routing
Actuates diverter gates on electronics manufacturing conveyor lines, utilizing the 245N push force and 550mm stroke to shift printed circuit boards between inspection stations.
Carton Push-off Arm
Pushes packaged product from a palletizing robot zone, where the 206N pull force reliably retracts the 10mm rod over 550mm to clear the packaging area.
Textile Yarn Guide
Traverses a yarn threading mechanism across a weaving loom, requiring the exact 550mm travel and the U flat-end cover for rigid, straight-line mounting.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X550-S-U with MBL25X550-S-U
To replace the MAL25X550-S-U, order the MBL25X550-S-U, ensuring you keep the U flat-end back cover and the -S magnet. Note that the -S magnet on the MBL requires current CMSG / DMSG / EMSG switches rather than the legacy CS1-M / DS1-M sensors. Because this is a 550mm non-standard stroke exceeding the 500mm standard limit, it is manufactured to order. At 0.5 MPa, the 25mm bore yields 245N push force; if you need less force, step down to the 20mm bore (157N push), or step up to the 32mm bore (402N push) for more power.
With a 550mm stroke on a 10mm rod, side-load tolerance is minimal and the rod is highly susceptible to bending. You must use an external guide rail or a pivot mount to prevent seal failure. Additionally, the fixed rubber bumper softens end-of-stroke impacts but does not lock the rod; a plain MBL will drift when air pressure is lost, so an external rod lock or pilot-operated check valve is required to hold a vertical load.
Upgrade checklist
- ✓ Order the MBL25X550-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 MBL25X550-S-U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X550-S-U FAQ
Yes, the MAL series is end-of-life. The exact drop-in replacement is the MBL25X550-S-U, offering the same 25mm bore, 550mm stroke, G1/8 port, U flat-end cover, and -S magnet. You only need to update your position sensors from the older CS1-M / DS1-M to the current CMSG / DMSG / EMSG family.
The 25mm bore generates 245N push and 206N pull at 0.5 MPa, 343N push at 0.7 MPa, and a maximum theoretical force of 50 kgf at 1.0 MPa. The -S code means it has a built-in magnet for CS1-M / DS1-M switches on the MAL, while the MBL replacement requires CMSG / DMSG / EMSG sensors.
