This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL20X115U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL20X115U 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 MAL20X115U
The AirTAC Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X115U is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 115mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL20X115U, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X115U
The AirTAC MAL20X115U is a discontinued double-acting aluminum mini round cylinder with a 20mm bore and 115mm stroke. It delivers 157N of push force and 132N of pull force at 0.5MPa. The exact drop-in replacement is the MBL20X115U, matching the bore, stroke, output, G1/8 port, and U flat-end back cover. The legacy MAL uses threaded front and rear covers, whereas the modern MBL features a riveted rolling-packed body for equally robust performance.
Because this specific SKU lacks an -S magnet, it cannot accept a position sensor. The 8mm carbon-steel rod features 20um hard-chrome plating and runs through a self-lubricating front-cover bearing guide. A heterogeneous two-way seal retains grease internally, ensuring smooth extension and retraction without external lubrication.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL20X115U 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 MBL20X115U 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 MAL20X115U Is Used
PCB Router Gating
Pushes a small pneumatic gate to route printed circuit boards exiting a depaneling machine, using the 115mm stroke to clear the work zone.
Carton Flap Folder
Tucks the minor flaps on small electronics packaging lines, applying 157N of push force at 0.5MPa without crushing the corrugated board.
Test Tube Ejection
Extends 115mm to eject filled microcentrifuge tubes from a diagnostic carousel, relying on the compact 20mm body to fit between dense racks.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X115U with MBL20X115U
To replace the MAL20X115U, order the MBL20X115U. Verify your 20mm bore, 115mm stroke, G1/8 port, default PT thread, and the U flat-end rigid back cover. Since this SKU has no -S magnet, you cannot mount a sensor; if you need position detection, specify an MBL20X115US and upgrade to the current CMSG, DMSG, or EMSG switch family (the old CS1-M/DS1-M sensors are retired). If you need adjustable end-cushioning to soften the 115mm travel, step up to the MBLC variant, as the MAL only has a fixed rubber bumper.
For sizing flexibility, the neighboring 25mm bore provides 245N push at 0.5MPa if you need more force, while this 20mm bore is the smallest available in the series. At 115mm of stroke, the 8mm rod has low side-load tolerance; use an external guide rail to prevent rod bending on arcing loads. Note that a plain MAL or MBL does not hold its position if air pressure drops—the bumper only softens the end of travel, so add a rod lock for vertical loads.
Upgrade checklist
- ✓ Order the MBL20X115U (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 MBL20X115U instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X115U FAQ
Yes, the MAL20X115U is discontinued. The exact drop-in replacement is the MBL20X115U. It matches the 20mm bore, 115mm stroke, G1/8 port, and U flat-end cover. You can swap it directly without changing your mounting hardware.
At 0.5MPa, the push force is 157N and the pull force is 132N. At 0.7MPa, the push force is 220N. The maximum theoretical force is 32kgf at 1.0MPa.
