This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X150-U-H — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X150-U-H 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-U-H
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X150-U-H 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-U-H, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X150-U-H
The AirTAC MAL25X150-U-H is a discontinued compact double-acting aluminum mini round cylinder with a 25 mm bore and 150 mm stroke. It delivers 245 N push and 206 N pull at 0.5 MPa, operating on a G1/8 port with a 10 mm carbon-steel rod. AirTAC replaced this legacy unit with the MBL25X150-U-H, a drop-in alternative that matches the exact bore, stroke, output force, port size and U flat-end mounting. The U designation denotes a rigid flat-end back cover, suited for straightforward inline anchoring without articulation.
This specific SKU lacks a -S magnet, meaning it cannot support a position sensor and is intended for simple extend-and-retract cycles. The original MAL body relied on threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed barrel for structural rigidity. Both generations use a fixed rubber bumper to soften end-of-stroke impacts rather than an adjustable air cushion. Internally, a heterogeneous two-way seal retains grease, and a self-lubricating front-cover bearing guide supports the hard-chrome plated rod.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X150-U-H 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-U-H 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-U-H Is Used
PCB Depaneling Router
Drives the cutting head on an electronic PCB depaneling router, using the 245 N push force at 0.5 MPa to separate routed circuit boards without stressing the substrate.
Carton Flap Folder
Folds minor product carton flaps on a compact packaging line, where the 150 mm stroke provides the exact travel needed to clear the box path before retraction.
Connector Insertion Press
Pushes ribbon cable connectors into PCB sockets during electronics assembly, relying on the rigid U flat-end back cover to maintain alignment under 206 N pull force.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X150-U-H with MBL25X150-U-H
To replace the MAL25X150-U-H, order the MBL25X150-U-H. Confirm the 25 mm bore, 150 mm stroke, G1/8 port, and the U flat-end back cover. Because this SKU has no -S magnet, it cannot accept a sensor; if you need position detection, step up to an MBL variant with an S code, which will require the newer CMSG, DMSG or EMSG switch family instead of the legacy CS1-M or DS1-M sensors. The fixed rubber bumper is adequate for standard cycling, but if your load requires adjustable end-cushioning, look at the current MBLC line.
If you are re-evaluating force requirements, the next size down is the 20 mm bore (providing 157 N push at 0.5 MPa) and the next size up is the 32 mm bore (providing 403 N push at 0.5 MPa). Because the 150 mm stroke is substantial for a 10 mm rod, side-load tolerance is low; use an external guide rail or a pivot mounting accessory to prevent rod bending. Note that a plain cylinder does not hold its position when air pressure is lost—a pilot-operated check valve is required for fail-safe load holding.
Upgrade checklist
- ✓ Order the MBL25X150-U-H (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-U-H instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X150-U-H FAQ
Yes, the MAL series is discontinued. The exact drop-in replacement is the MBL25X150-U-H. It matches the 25 mm bore, 150 mm stroke, G1/8 port, and U flat-end mounting. The main upgrade is a riveted rolling-packed body replacing the older threaded covers, but the force and dimensions remain identical.
At 0.5 MPa, the push force is 245 N and the pull force is 206 N. At 0.7 MPa, the push force is 343 N, with a theoretical maximum of 50 kgf at 1.0 MPa. Because this specific SKU lacks a -S magnet, it cannot accept a position sensor; legacy MAL sensors were CS1-M or DS1-M, while the MBL replacement uses CMSG, DMSG or EMSG switches.
