This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X90U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X90U 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 MAL25X90U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X90U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 90mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X90U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X90U
The AirTAC MAL25X90U is a discontinued double-acting aluminum mini round cylinder featuring a 25mm bore and 90mm stroke. It delivers 245N push and 206N pull force at 0.5MPa, utilizing a G1/8 port and an M10x1.25 rod-end thread. The exact drop-in replacement is the MBL25X90U, which matches the bore, stroke, output force, port size, and mounting accessories perfectly.
This specific SKU includes a U flat-end back cover for rigid rear mounting and lacks a magnet, meaning it cannot support position sensing. The legacy MAL body relies on threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed body. Both designs use a fixed rubber bumper for end-of-stroke deceleration and a heterogeneous two-way seal that retains grease around the 20um hard-chrome plated carbon-steel rod.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X90U 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 MBL25X90U 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 MAL25X90U Is Used
PCB Router Ejection
Uses the 245N push at 0.5MPa to eject 90mm long cut PCB panels from a routing machine, relying on the rigid U flat-end cover to maintain strict perpendicular alignment.
Carton Flap Folder
Folds small corrugated carton flaps in a compact packaging line where the 206N pull force securely retracts the 10mm rod clear of the product path.
Small Parts Sorter Gate
Actuates a 90mm diversion gate for sorted electronic resistors, where the fixed rubber bumper absorbs the repetitive end-of-stroke impact without adjustment.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X90U with MBL25X90U
To replace the MAL25X90U, order the MBL25X90U and verify your 90mm stroke, 25mm bore, G1/8 port, and PT thread form. Confirm the U flat-end back cover for rigid mounting, and note that because this SKU lacks an -S magnet, no position sensor can be attached. If your application requires an adjustable air cushion rather than the standard fixed rubber bumper, step up to the current MBLC line.
When sizing, consider the neighbouring bores: stepping down to 20mm drops the 0.5MPa push force to 157N, while stepping up to 32mm increases it to 402N. Because this cylinder has a 90mm stroke, side-load stress on the 10mm rod is moderate, but rigid U-mounting requires careful alignment. A plain MAL or MBL cylinder does not hold its load when air pressure is lost; the rod will drift, so use an external rod lock or pilot-operated check valve for fail-safe position holding.
Upgrade checklist
- ✓ Order the MBL25X90U (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 MBL25X90U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X90U FAQ
Yes, the MAL25X90U is discontinued. The exact drop-in replacement is the MBL25X90U, offering the same 25mm bore, 90mm stroke, 245N push force at 0.5MPa, G1/8 port, and U flat-end mounting. The modern MBL uses a riveted rolling-packed body instead of threaded covers.
At 0.5MPa it provides 245N push and 206N pull force, increasing to 343N push at 0.7MPa, with a theoretical maximum of 50kgf at 1.0MPa. Because this specific SKU lacks a built-in magnet, it cannot support CS1-M or DS1-M position sensors; the MBL replacement requires an -S suffix to use CMSG, DMSG, or EMSG switches.
