This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL20X25CAH — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL20X25CAH 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 MAL20 Aluminum Alloy Mini Cylinder MAL20X25CAH
The AirTAC Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X25CAH 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 drop-in replacement is the MBL20X25CAH, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X25CAH
The AirTAC MAL20X25CAH is a discontinued compact double-acting aluminum mini round cylinder engineered for tight spaces. Delivering 157 N of push force at 0.5 MPa, it features a 20 mm bore, 25 mm stroke, and a G1/8 port. The exact drop-in replacement is the MBL20X25CAH, matching the original bore, stroke, output force, port size, and CA pivot mounting.
This legacy MAL cylinder relies on a threaded front and back cover assembly, whereas the modern MBL replacement features a riveted rolling-packed body for enhanced structural integrity. Because this specific SKU lacks a magnet (-S), it cannot accept a position sensor. The piston utilizes a heterogeneous two-way seal that retains grease, paired with a self-lubricating front-cover bearing guide to support the Ø8 mm carbon-steel rod with 20 um hard-chrome plating.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL20X25CAH carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | — |
| Max (@1.0 MPa) | 32 kgf | |
The MBL20X25CAH 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 MAL20 Aluminum Alloy Mini Cylinder MAL20X25CAH Is Used
PCB Router Clamping
Secures small printed circuit boards during routing with 157 N of push force, while the CA clevis allows the fixture to pivot slightly for alignment.
Sensor Bracket Indexing
Moves delicate optical sensor brackets in a tight electronics assembly, relying on the 25 mm stroke and self-lubricating bearing for smooth actuation.
Vial Tray Deflection
Pushes lightweight sample vial trays out of a dispensing lane, using the compact 20 mm body to fit within crowded laboratory housings.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X25CAH with MBL20X25CAH
To replace the MAL20X25CAH, order the MBL20X25CAH. Verify your 20 mm bore, 25 mm stroke, PT tapered port thread, and the CA pivot back cover, which swings on a pin to accommodate arcing loads. If your application requires an adjustable air cushion rather than the fixed rubber bumper found on this MAL, step up to the current-line MBLC series.
For sizing flexibility, stepping down is not an option as 20 mm is the smallest available bore. If you need more power, the next size up is the 32 mm bore, which provides 402 N of push force at 0.5 MPa. Note that this non-magnet SKU cannot support a sensor; if you need position detection, order an MBL with the -S option and use CMSG, DMSG, or EMSG switches instead of the older CS1-M or DS1-M. A plain bumper does not hold the load if air pressure drops; install an external rod lock for vertical safety.
Upgrade checklist
- ✓ Order the MBL20X25CAH (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 MBL20X25CAH instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X25CAH FAQ
Yes, the MAL20X25CAH is discontinued. The exact drop-in replacement is the MBL20X25CAH, which matches the 20 mm bore, 25 mm stroke, G1/8 port, and CA pivot mounting. You will notice the MBL uses a riveted rolling-packed body instead of the original threaded covers.
At 0.5 MPa, the push force is 157 N and the pull force is 132 N. At 0.7 MPa, the push force is 220 N. The maximum theoretical force is 32 kgf at 1.0 MPa. This SKU lacks a magnet, so it cannot use CS1-M or DS1-M position sensors.
