This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X150-S-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X150-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 MAL25X150-S-U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X150-S-U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 150mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X150-S-U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X150-S-U
The AirTAC MAL25X150-S-U is a discontinued double-acting aluminum mini round cylinder featuring a 25mm bore and 150mm stroke. It delivers 245N push and 206N pull force at 0.5 MPa, utilizing a G1/8 port. The exact drop-in replacement is the MBL25X150-S-U, matching the bore, stroke, force, port, and mounting hardware.
This legacy SKU includes a U flat-end back cover for rigid rear mounting and a built-in magnet (-S). The original MAL body uses threaded front and back covers, whereas the modern MBL uses a riveted rolling-packed body. Because this unit has an -S magnet, it originally paired with CS1-M or DS1-M reed switches; upgrading to the MBL requires switching to the current CMSG, DMSG, or EMSG sensor family. The 10mm carbon-steel rod has 20 um hard chrome plating, supported by a self-lubricating bearing guide.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X150-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 MBL25X150-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 MAL25X150-S-U Is Used
PCB Router Ejection
Pushes machined printed circuit boards out of a routing fixture using 245N of force at 0.5 MPa over the 150mm travel distance.
Carton Flap Folding
Actuates a small cardboard flap folder on a compact packaging line, relying on the U flat-end cover for rigid rear frame mounting.
Small Parts Shuttle
Moves lightweight plastic components between robotic pick stations, utilizing the built-in magnet for end-of-stroke position detection.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X150-S-U with MBL25X150-S-U
To replace the MAL25X150-S-U, order the MBL25X150-S-U to retain the 25mm bore, 150mm stroke, G1/8 PT port, U flat-end cover, and magnet. If you need less force, step down to the 20mm bore (157N push at 0.5 MPa); if you need more, step up to the 32mm bore (402N push at 0.5 MPa). The 150mm stroke requires a side-load check: the 10mm rod has low lateral tolerance, so use an external guide rail to prevent rod bending. The fixed rubber bumper softens end-of-stroke impacts but does not lock the rod; if position holding is required when air pressure drops, install an external pilot-operated check valve. For adjustable air cushioning, specify the MBLC variant instead of the MBL.
Upgrade checklist
- ✓ Order the MBL25X150-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 MBL25X150-S-U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X150-S-U FAQ
Yes, the MAL25X150-S-U is discontinued. The exact drop-in replacement is the MBL25X150-S-U, which matches the 25mm bore, 150mm stroke, 245N force, G1/8 port, and U flat-end mounting. You must upgrade your sensors: the MAL -S magnet works with CS1-M / DS1-M switches, while the MBL uses CMSG / DMSG / EMSG switches.
The 25mm bore provides 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 port size is G1/8, and the rod end thread is M10x1.25.
