This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X450-S-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X450-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 MAL25X450-S-U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X450-S-U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 450mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X450-S-U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X450-S-U
The AirTAC MAL25X450-S-U is a discontinued compact double-acting aluminum mini round cylinder. It delivers 245 N of push force and 206 N of pull force at 0.5 MPa. Because this legacy series has ended production, AirTAC provides the MBL25X450-S-U as the exact drop-in replacement. This newer model matches the 25 mm bore, 450 mm stroke, G1/8 port, and U flat-end back cover perfectly, ensuring a seamless physical retrofit.
This specific SKU includes a built-in magnet (-S) for position detection. On the MAL, this magnet interfaces with the older CS1-M and DS1-M reed switches, whereas the MBL replacement upgrades to the current CMSG, DMSG, or EMSG sensor families. Structurally, the legacy MAL relies on threaded front and back covers, while the modern MBL features a riveted rolling-packed body. Both designs share a fixed rubber bumper for end-of-stroke deceleration. If your application requires an adjustable air cushion, you must step up to the MBLC variant on the current line, as the MAL never offered this feature.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X450-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 MBL25X450-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 MAL25X450-S-U Is Used
PCB Conveyor Diverter
Uses the 245 N push force at 0.5 MPa to deflect populated circuit boards on a tight-space conveyor, relying on the 450 mm stroke to clear the production lane.
Pallet Push-Off Station
Cycles small packaging pallets out of a machining cell, where the 10 mm carbon-steel hard-chrome rod withstands repetitive lateral friction during the ejection stroke.
Textile Yarn Guide
Traverses a yarn tensioning carriage across a 450 mm span, requiring the -S magnet and a CS1-M switch to trigger reverse direction at the exact stroke endpoints.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X450-S-U with MBL25X450-S-U
To replace the MAL25X450-S-U, order the MBL25X450-S-U. Verify your setup retains the PT tapered port thread (G1/8) and the M10x1.25 rod-end thread. The U code denotes a rigid flat-end back cover, which is ideal for fixed mounting but cannot absorb angular rod drift. Because this is a 450 mm stroke on a 10 mm rod, side-load tolerance is minimal; you must use an external guide rail to prevent rod bending and premature seal wear.
When sizing, consider stepping down to the 20 mm bore (157 N push @0.5 MPa) if your payload is light, or stepping up to the 32 mm bore (402 N push @0.5 MPa) for heavier masses. Note that a plain MBL does not hold a load when air pressure drops—the rod will drift. Install a pilot-operated check valve or an external rod lock if you need fail-safe position holding.
Upgrade checklist
- ✓ Order the MBL25X450-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 MBL25X450-S-U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X450-S-U FAQ
Yes, the MAL series is end-of-life. The exact drop-in replacement is the MBL25X450-S-U, which matches the 25 mm bore, 450 mm stroke, G1/8 port, and U flat-end cover. The -S magnet still functions, but you must upgrade from the old CS1-M / DS1-M switches to the modern CMSG / DMSG / EMSG sensors.
At 0.5 MPa, the push force is 245 N and the pull force is 206 N. At 0.7 MPa, the push force increases to 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa. It operates at 0.1-1.0 MPa with a speed range of 30-800 mm/s.
