This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X550-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X550-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-U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X550-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-U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X550-U
The AirTAC MAL25X550-U is a discontinued compact double-acting aluminum mini round cylinder with a 25mm bore and a 550mm stroke. Because the stroke exceeds the 500mm standard maximum, this is a non-standard, made-to-order unit. It delivers 245N of push force and 206N of pull force at 0.5 MPa. The exact drop-in replacement is the MBL25X550-U, which matches the bore, stroke, output force, G1/8 port, and U flat-end back cover perfectly.
This legacy SKU features a U flat-end back cover for rigid mounting, and because it lacks the -S code, it cannot accept a position sensor. The original MAL body uses threaded front and back covers, whereas the current MBL replacement features a riveted rolling-packed body for enhanced structural integrity. Inside, the piston relies on a heterogeneous two-way seal that retains grease, riding on a carbon-steel rod with 20um hard-chrome plating.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X550-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-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-U Is Used
Pallet Transfer Pusher
Pushes light pallets along a 550mm conveyor section using 245N of thrust at 0.5 MPa, relying on an external guide to absorb side loads over the long stroke.
Tote Box Diverter
Diverts small packaging totes at a sorting station, where the rigid U flat-end back cover mounts solidly to the machine frame without pivot arcing.
Film Roll Tensioner
Actuates a tensioning arm for packaging film rolls, benefiting from the self-lubricating front-cover bearing guide to maintain smooth 30-800 mm/s operation.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X550-U with MBL25X550-U
To replace the MAL25X550-U, order the MBL25X550-U. Verify your setup accommodates the U flat-end rigid back cover and the default PT tapered port thread. If you need to adjust the bore size, stepping down to the 20mm bore yields 157N push at 0.5 MPa, while stepping up to the 32mm bore provides 402N push at 0.5 MPa.
Since this is a 550mm stroke on a 10mm rod, side-load tolerance is extremely low; you must use an external guide rail to prevent rod bending. Note that this SKU lacks a magnet, so no sensor can be used. The MAL uses a fixed rubber bumper, not an adjustable cushion—if end-of-stroke damping is required, look to the MBLC variant on the current line. A plain cylinder does not hold its load when air is lost; the rod will drift, requiring an external rod lock for fail-safe holding.
Upgrade checklist
- ✓ Order the MBL25X550-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-U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X550-U FAQ
Yes, the MAL series is end-of-life. The exact drop-in replacement is the MBL25X550-U, which matches the 25mm bore, 550mm stroke, 245N push force, G1/8 port, and U flat-end cover. You can order the MBL as a direct retrofit.
At 0.5 MPa, it provides 245N push and 206N pull; at 0.7 MPa it provides 343N push, with a maximum theoretical force of 50 kgf at 1.0 MPa. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor; the MBL replacement with -S uses CMSG/DMSG/EMSG switches.
