This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X40U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X40U 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 MAL25X40U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X40U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 40mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X40U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X40U
The AirTAC MAL25X40U is a discontinued compact double-acting aluminum mini round cylinder engineered 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, 40 mm stroke, and a G1/8 port. AirTAC replaced this legacy unit with the MBL25X40U, a drop-in alternative retaining the exact same output, porting, and U flat-end rear cover dimensions.
This SKU features a U flat-end back cover for rigid, non-articulating mounting. Because this specific configuration lacks the -S magnet option, it cannot accept a position sensor. The original MAL body utilized threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed body for faster assembly. Both designs rely on a fixed rubber bumper at the stroke ends rather than an adjustable air cushion.

| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.1 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Fixed rubber bumper |

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X40U 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 MBL25X40U 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 MAL25X40U Is Used
PCB Depaneling Gate
Provides 245 N of push force at 0.5 MPa to actuate a routing gate on a PCB depaneling machine, fitting neatly into tight electronics assembly cells.
Connector Insertion Press
Cycles a 40 mm stroke to seat pin headers into plastic housings, relying on the rigid U flat-end cover to maintain strict perpendicularity during the press fit.
Carton Flap Folder
Uses its 206 N pull force to retract a mechanical flap-folding arm on a small packaging line, operating at speeds between 30 and 800 mm/s.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X40U with MBL25X40U
To replace the MAL25X40U, order the MBL25X40U. Verify your setup accommodates the 25 mm bore, 40 mm stroke, PT tapered port threads, and the rigid U flat-end back cover. If your application requires end-of-stroke cushioning, you must step up to the current MBLC series, as the MAL only provides a fixed rubber bumper. If you need position detection, this non-magnet SKU cannot support it; you would need an MBL25X40US and the current CMSG/DMSG/EMSG switch family.
For sizing flexibility, stepping down to a 20 mm bore drops the push force to 157 N at 0.5 MPa, while stepping up to a 32 mm bore increases it to 402 N. Keep in mind that a plain MAL or MBL cylinder does not hold its load when air pressure is lost; the rod will drift. For suspended loads, install an external pilot-operated check valve. At 40 mm, side-load risk is minimal, but the 10 mm carbon-steel rod still has low tolerance for off-center forces.
Upgrade checklist
- ✓ Order the MBL25X40U (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 MBL25X40U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X40U FAQ
Yes, the MAL25X40U is discontinued. The exact drop-in replacement is the MBL25X40U, which matches the 25 mm bore, 40 mm stroke, G1/8 port, and U flat-end mounting. The MBL features a riveted rolling-packed body instead of the older threaded covers, but performance is identical.
At 0.5 MPa, it delivers 245 N push and 206 N pull. At 0.7 MPa, push force is 343 N, with a maximum theoretical output of 50 kgf at 1.0 MPa. Because this SKU lacks the -S magnet, it cannot support position sensors; legacy -S models used CS1-M or DS1-M switches, while the MBL replacement uses CMSG, DMSG, or EMSG sensors.
