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

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X550-CA
The AirTAC MAL25X550-CA is a discontinued double-acting aluminum mini round cylinder with a 25mm bore and a 550mm stroke. Because 550mm exceeds the 500mm standard limit, this is a non-standard, made-to-order stroke. It delivers 245N of push force and 206N of pull force at 0.5MPa. The exact drop-in replacement is the MBL25X550-CA, which matches the bore, stroke, force, G1/8 port, and CA pivot mounting.
This legacy MAL unit features threaded front and back covers, whereas the modern MBL replacement uses a riveted rolling-packed body. The CA back cover acts as a pivot clevis that swings on a pin to absorb arcing loads. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor. The piston relies on a heterogeneous two-way seal that retains grease, and the carbon-steel rod has 20um hard chrome plating.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X550-CA 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-CA 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-CA Is Used
Textile Loom Tentering
Guides fabric panels through long drying frames using the 245N push force, where the CA pivot clevis accommodates the slight arcing motion of the swinging guide arms.
Pallet Strap Dispenser
Feeds binding straps across a wide 550mm conveyor gap, relying on the 10mm hard-chrome rod to extend and retract smoothly without lateral binding.
Warehouse Carton Flap Folder
Folds large corrugated box flaps on a packaging line, utilizing the 206N pull force to retract the 550mm arm clear of the product flow.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X550-CA with MBL25X550-CA
To replace this cylinder, order the MBL25X550-CA. Verify your pivot pin matches the CA clevis, and confirm the PT tapered port thread. If you need position sensing, you must move to an MBL with the -S option, which uses the modern CMSG, DMSG, or EMSG switches instead of the older CS1-M/DS1-M. If you need adjustable end-of-stroke cushioning to absorb kinetic energy, look at the MBLC variant, as the MAL only has a fixed rubber bumper.
At 550mm, the 10mm rod is highly susceptible to bending under side loads; always use an external guide rail. If you need less force, step down to the 20mm bore (157N push at 0.5MPa). If you need more force, step up to the 32mm bore (402N push at 0.5MPa). A plain bumper does not hold the load if air pressure drops; add an external rod lock for fail-safe positioning.
Upgrade checklist
- ✓ Order the MBL25X550-CA (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-CA instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X550-CA FAQ
Yes, the MAL series is end-of-life. The exact drop-in replacement is the MBL25X550-CA, offering the same 25mm bore, 550mm stroke, CA pivot mounting, and G1/8 port. The MBL upgrades the body to a riveted rolling-packed design.
At 0.5MPa it provides 245N push and 206N pull; at 0.7MPa it provides 343N push, with a maximum theoretical force of 50kgf at 1.0MPa. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor.
