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

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X150-U
The AirTAC MAL25X150-U is a discontinued compact double-acting aluminum mini round cylinder. Delivering 245 N of push force and 206 N of pull force at 0.5 MPa, it features a 25 mm bore, 150 mm stroke, and a G1/8 port. The exact drop-in replacement is the MBL25X150-U, which matches the bore, stroke, output force, port size, and flat-end mounting.
This legacy SKU uses a U flat-end back cover for rigid rear mounting. Because this specific model lacks the -S magnet code, it cannot accept a position sensor. The original MAL body uses threaded front and back covers, whereas the current MBL replacement features a riveted rolling-packed body for equally robust performance. The carbon-steel rod has 20 um hard chrome plating, and the self-lubricating front-cover bearing guide extends operational life.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X150-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-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-U Is Used
PCB Shuttle Gate
Cycles a 150 mm stroke to divert populated electronics boards on a conveyor at 245 N push force, fitting neatly into tight machine frames.
Carton Flap Folder
Pushes corrugated packaging flaps at 206 N pull force, relying on the rigid U flat-end back cover to maintain alignment without pivot wear.
Small Parts Ejector
Ejects stamped metal clips from a die over 150 mm, using the self-lubricating front-cover bearing guide to handle rapid 30-800 mm/s cycling.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X150-U with MBL25X150-U
To replace the MAL25X150-U, order the MBL25X150-U. Verify your 150 mm stroke, 25 mm bore, G1/8 port, and PT tapered thread. The U flat-end back cover provides rigid mounting, but if your machine requires arcing movement, consider switching to the CA pivot clevis version in the MBL line. Since this SKU has no -S magnet, it cannot support a sensor; if you need end-of-stroke detection, order the MBL25X150-S-U and upgrade to the modern CMSG, DMSG, or EMSG switch family, as the older CS1-M and DS1-M sensors are incompatible with the new body.
For sizing flexibility, stepping down to the 20 mm bore yields 157 N of push force at 0.5 MPa, while stepping up to the 32 mm bore provides 402 N. At 150 mm of stroke, the 10 mm rod is susceptible to bending under side loads; use an external guide rail or an SDB pivot bracket to prevent rod damage. The MAL uses a fixed rubber bumper, not an adjustable cushion; if your load requires precise end-of-stroke deceleration, specify the MBLC variant. Remember that a plain MAL or MBL cylinder does not hold its load when air pressure drops, so add an external rod lock or pilot-operated check valve for fail-safe holding.
Upgrade checklist
- ✓ Order the MBL25X150-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-U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X150-U FAQ
Yes, the MAL series is end-of-life. The exact drop-in replacement is the MBL25X150-U, which shares the same 25 mm bore, 150 mm stroke, G1/8 port, and 50 kgf maximum force. The MBL upgrades the body to a riveted rolling-packed design instead of the threaded covers found on the MAL.
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. The fixed rubber bumper only softens the end of stroke; it does not lock the rod, so the cylinder cannot hold a load when air pressure is lost.
