This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement MBL20X25SU, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 MAL20 Aluminum Alloy Mini Cylinder MAL20X25-S-U
The AirTAC MAL20 Aluminum Alloy Mini Cylinder MAL20X25-S-U is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 25mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the direct replacement is the MBL20X25-S-U, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X25-S-U
The AirTAC MAL20X25-S-U is a discontinued compact double-acting aluminum mini round cylinder. As the smallest standard bore in the legacy range, it delivers a 157 N push force and 132 N pull force at 0.5 MPa, utilizing an 8 mm carbon-steel rod with 20 um hard chrome plating. Because this unit includes the -S magnet, it originally paired with CS1-M or DS1-M reed switches for end-of-stroke detection.
AirTAC replaced this end-of-life series with the MBL20X25-S-U, a direct alternative retaining the exact 20 mm bore, 25 mm stroke, G1/8 port, and U flat-end back cover. While the original MAL features threaded front and back covers, the upgraded MBL utilizes a riveted rolling-packed body for enhanced structural integrity. The internal piston relies on a heterogeneous two-way seal that retains grease, and a self-lubricating front-cover bearing guide supports the rod.

Where the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X25-S-U Is Used
PCB Router Ejection
Deploys a 25 mm stroke to push singulated circuit boards out of a high-speed router tray using 157 N of push force at 0.5 MPa.
Pharmaceutical Vial Sorting
Acts as a compact diverter in tight packaging lanes, using the U flat-end cover to mount rigidly against a starwheel guide rail.
Micro-Clamp Actuation
Provides 132 N of pull force at 0.5 MPa to retract a small holding jaw inside a 20 mm bore assembly fixture for lightweight plastic components.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X25-S-U with MBL20X25-S-U
To replace the MAL20X25-S-U, order the MBL20X25-S-U, ensuring you match the 20 mm bore, 25 mm stroke, M8x1.25 rod-end thread, and default PT port. If your application requires stepping down a size, note that 20 mm is the smallest available bore in this series. If you need more force, the next size up is the 25 mm bore, which provides 245 N of push force at 0.5 MPa. Be aware that the -S magnet on your legacy unit used CS1-M / DS1-M sensors, but the MBL replacement requires the modern CMSG / DMSG / EMSG switch family.
This cylinder features a U flat-end back cover for rigid, non-pivoting mounting. A plain MAL or MBL cylinder cannot hold a load when air pressure is lost, as the rod will drift; use an external rod lock or pilot-operated check valve for fail-safe positioning. Additionally, the MAL relies on a fixed rubber bumper for end-of-stroke deceleration, whereas the current-line MBLC offers an adjustable air cushion if your application demands softer stops.
Upgrade checklist
- ✓ Order the MBL20X25-S-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 MBL20X25-S-U instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X25-S-U FAQ
Yes, the MAL20X25-S-U is discontinued. The direct replacement is the MBL20X25-S-U, which matches the 20 mm bore, 25 mm stroke, G1/8 port, and U flat-end cover. Note that the -S magnet on the MBL works with CMSG / DMSG / EMSG switches, replacing the older CS1-M / DS1-M sensors.
The 20 mm bore generates a push force of 157 N and a pull force of 132 N at 0.5 MPa. At 0.7 MPa, the push force is 220 N. The maximum theoretical force is 32 kgf at 1.0 MPa.
