This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X20SUH — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X20SUH 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 MAL25X20SUH
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X20SUH is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 20mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X20SUH, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X20SUH
The AirTAC MAL25X20SUH is a discontinued compact double-acting aluminum mini round cylinder. It delivers a 245 N push force and 206 N pull force at 0.5 MPa, utilizing a 10 mm carbon-steel rod with a 20 um hard-chrome plating to handle short 20 mm strokes. AirTAC replaced this legacy unit with the MBL25X20SUH, a drop-in alternative retaining the exact same bore, stroke, output force, G1/8 port, and U flat-end mounting interface.
This specific SKU includes a U flat-end back cover for rigid, fixed alignment rather than arcing pivot loads. It also features the -S magnet for position detection, which on the MAL works with older CS1-M / DS1-M switches; upgrading to the MBL means switching to the current CMSG / DMSG / EMSG sensor family. The original MAL uses threaded front and back covers, whereas the MBL replacement features a riveted rolling-packed body. A heterogeneous two-way grease-retaining seal keeps the self-lubricating front-cover bearing guide lubricated for millions of cycles.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X20SUH Technical Specifications

| Stroke | 20 mm |
| Acting type | Double acting |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| 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 |
| Max standard stroke | Up to 500 mm |
Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X20SUH 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 MBL25X20SUH 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 MAL25X20SUH Is Used
PCB Depaneling Ejector
Provides 245 N of push force at 0.5 MPa to eject cut printed circuit boards from depaneling routers in tight electronics assembly cells.
IC Test Handler Clamper
Uses its 20 mm stroke and flat-end U cover to secure integrated circuit trays during high-speed automated test handling without arcing loads.
Pouch Sealing Jaws
Cycles rapidly at 30-800 mm/s to close heat-sealing jaws on small pharmaceutical pouch packaging lines, relying on the fixed rubber bumper.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X20SUH with MBL25X20SUH
To replace the MAL25X20SUH, order the MBL25X20SUH, keeping the 25 mm bore, 20 mm stroke, G1/8 port, PT thread, U flat-end back cover, and -S magnet. Because this SKU has the -S magnet, plan to upgrade your existing CS1-M or DS1-M sensors to the CMSG, DMSG, or EMSG series to fit the MBL body. If your application requires an adjustable air cushion rather than the fixed rubber bumper found on the MAL, step up to the MBLC variant on the current line. A plain MAL or MBL does not hold its position or load when air is lost—the rod drifts—so add an external rod lock or pilot-operated check valve for fail-safe load holding.
For sizing, this 25 mm bore provides 245 N push at 0.5 MPa. If you need less force, step down to the 20 mm bore (157 N push at 0.5 MPa). If you need more force, step up to the 32 mm bore (402 N push at 0.5 MPa).
Upgrade checklist
- ✓ Order the MBL25X20SUH (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 MBL25X20SUH instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X20SUH FAQ
Yes, the MAL25X20SUH is discontinued. The exact drop-in replacement is the MBL25X20SUH, which matches the 25 mm bore, 20 mm stroke, 245 N force, G1/8 port, and U flat-end mounting. You must update your sensors from the older CS1-M / DS1-M to the CMSG / DMSG / EMSG series.
The 25 mm bore generates a 245 N push and 206 N pull at 0.5 MPa, a 343 N push at 0.7 MPa, and a maximum theoretical force of 50 kgf at 1.0 MPa. It uses a 10 mm carbon-steel rod with an M10x1.25 rod-end thread.
