This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X25-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X25-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 MAL25X25-U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X25-U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 25mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X25-U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X25-U
The AirTAC MAL25X25-U is a discontinued compact double-acting aluminum mini round cylinder designed for tight spaces. Delivering 245 N of push force and 206 N of pull force at 0.5 MPa, it features a 25 mm bore, a 25 mm stroke, and a G1/8 port. Because this legacy unit has reached end-of-life, AirTAC replaced it with the MBL25X25-U, a drop-in alternative retaining the exact same bore, stroke, output force, port size, and flat-end mounting interface.
This specific SKU features a U flat-end back cover for rigid mounting and lacks an S designation, meaning it cannot accommodate a position sensor. The original MAL body utilized threaded front and back covers, whereas the modern MBL replacement uses a riveted rolling-packed body for faster assembly. Both designs rely on a fixed rubber bumper for end-of-stroke deceleration rather than an adjustable air cushion. To manage internal friction, the piston employs a heterogeneous two-way seal that retains grease, complemented by a self-lubricating front-cover bearing guide that supports the 10 mm carbon-steel rod with 20 µm hard-chrome plating.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X25-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 MBL25X25-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 MAL25X25-U Is Used
PCB Depaneling Saw
Drives the linear blade guard on a compact PCB depaneling saw, utilizing the 245 N push force to shield the cutting carbide during 25 mm traverse cycles.
Vial Tray Stopper
Acts as a rigid stopper for incoming pharmaceutical vial trays, using the flat-end U cover to absorb the 25 mm stroke impact without rear pivot deflection.
Connector Pick-and-Place
Provides the vertical plunge for a small connector pick-and-place head, where the 206 N pull force safely retracts the 10 mm rod within a tight electronics assembly cell.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X25-U with MBL25X25-U
To replace the MAL25X25-U, order the MBL25X25-U, confirming the 25 mm bore, 25 mm stroke, G1/8 port, and default PT tapered thread. The U suffix dictates a rigid flat-end rear cover, so verify your mounting bracket can accept a fixed back. Since this SKU lacks an S magnet, it cannot accept a sensor; if position detection is now required, order an MBL25X25S-U and migrate to the current CMSG, DMSG, or EMSG switch family, as the older CS1-M and DS1-M sensors are obsolete. The cylinder uses a fixed rubber bumper; if your application demands adjustable end-cushioning, step up to the MBLC variant on the current line.
When sizing, evaluate stepping down to the 20 mm bore (157 N push at 0.5 MPa) for lighter loads, or up to the 32 mm bore (402 N push at 0.5 MPa) for higher thrust. Remember that a plain bumper does not hold the load when air pressure is lost; the rod will drift, so fit an external rod lock or pilot-operated check valve if position holding is critical.
Upgrade checklist
- ✓ Order the MBL25X25-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 MBL25X25-U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X25-U FAQ
Yes, the MAL series is end-of-life. The exact drop-in replacement is the MBL25X25-U, which matches the 25 mm bore, 25 mm stroke, G1/8 port, and flat-end U mounting. The main upgrade is that the MBL uses a riveted rolling-packed body instead of the MAL's threaded covers.
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. The maximum theoretical force is 50 kgf at 1.0 MPa. Note that this SKU lacks a magnet, so it cannot support a position sensor.
