This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X500-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X500-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 MAL25X500-U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X500-U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 500mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X500-U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X500-U
The AirTAC MAL25X500-U is a discontinued double-acting aluminum mini round cylinder featuring a 25mm bore and a 500mm stroke. As a compact actuator, it delivers 245N of push force and 206N of pull force at 0.5MPa. Because this legacy series has reached end-of-life, AirTAC replaced it with the MBL25X500-U, a drop-in alternative that matches the exact bore, stroke, output force, G1/8 port size, and U flat-end rear cover.
This specific SKU lacks a magnetic piston, meaning it cannot support position sensing out of the box. Structurally, the legacy MAL relies on threaded front and back covers, whereas the modern MBL replacement uses a riveted rolling-packed body for improved structural integrity. Both designs utilize a fixed rubber bumper to absorb end-of-stroke kinetic energy, though operators requiring adjustable air cushioning must step up to the current-line MBLC variant.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X500-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 MBL25X500-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 MAL25X500-U Is Used
PCB Conveyor Routing
Moves 500mm to shuttle bare PCBs between inspection stations, utilizing 245N push force to actuate lightweight aluminum routing gates.
Carton Labeling Pusher
Extends a 25mm bore actuator to apply backing pressure on corrugated cartons, relying on the rigid U flat-end cover to maintain alignment.
Pallet Diverter Arm
Deploys a 500mm stroke to kick standardized plastic pallets onto a secondary packaging line without overwhelming the 10mm rod.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X500-U with MBL25X500-U
To replace the MAL25X500-U, order the MBL25X500-U and verify your G1/8 port connection, PT tapered thread, and the rigid U flat-end back cover. If 245N of push force at 0.5MPa is insufficient, stepping up to the 32mm bore yields 402N; conversely, dropping down to the 20mm bore provides 157N. Since this configuration lacks the -S magnet, you cannot mount a CS1-M or DS1-M sensor, and the MBL upgrade will similarly require a non-magnetic base unless you specify -S.
At 500mm of travel, the 10mm carbon-steel rod is highly susceptible to bending under lateral stress. You must use an external guide rail or a pivot mounting accessory to prevent rod deformation. Furthermore, the fixed rubber bumper softens impacts but does not lock the load; if power drops, the rod will drift. Install an external pilot-operated check valve for position holding.
Upgrade checklist
- ✓ Order the MBL25X500-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 MBL25X500-U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X500-U FAQ
Yes, the MAL25X500-U is discontinued. The exact drop-in replacement is the MBL25X500-U, which matches the 25mm bore, 500mm stroke, 245N push force, G1/8 port, and U flat-end mounting.
At 0.5MPa it provides 245N push and 206N pull force, 343N push at 0.7MPa, and a maximum theoretical force of 50kgf at 1.0MPa. It uses a fixed rubber bumper, not an adjustable cushion.
