This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL20X210U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL20X210U 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 MAL20X210U
The AirTAC Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X210U is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 210mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL20X210U, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X210U
The AirTAC MAL20X210U is a discontinued compact double-acting aluminum mini round cylinder with a 20mm bore and 210mm stroke. It delivers 157N of push force at 0.5MPa. The exact drop-in replacement is the MBL20X210U, which matches the original bore, stroke, output force, G1/8 port, and flat-end U mounting.
This legacy unit features a threaded front and back cover design, whereas the modern MBL utilizes a riveted rolling-packed body for structural rigidity. Because this specific SKU lacks an -S magnet, it cannot accommodate a position sensor. The internal piston relies on a heterogeneous two-way seal that retains grease, while the 8mm carbon-steel rod features 20um hard-chrome plating to resist wear.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL20X210U 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 MBL20X210U 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 MAL20X210U Is Used
PCB Depaneling Router
Drives a routing blade to singulate assembled PCB panels, utilizing the 157N push force to cleanly cut through substrate materials.
Small Parts Ejector
Pushes lightweight plastic moldings out of a machining fixture using the 210mm stroke to clear the work area for the next cycle.
Chip Tray Sorter
Actuates a diverter gate on a conveyor belt to route microchip trays into secondary packaging lanes within tight machine envelopes.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X210U with MBL20X210U
To replace the MAL20X210U, order the MBL20X210U. Verify that your existing setup uses the default PT tapered port thread and the rigid U flat-end back cover. Since this SKU has no -S magnet, you cannot mount a sensor; if position detection is needed, upgrade to an MBL20X210US and use the current CMSG, DMSG, or EMSG switch family instead of the obsolete CS1-M/DS1-M.
If you need to adjust the force output, step down to the neighboring bore size or up to the 25mm bore. The MAL20X210U provides 157N push and 132N pull at 0.5MPa. The next size down is the 16mm bore (confirm its force from the datasheet), while the next size up is the 25mm bore, which boosts output to 245N push and 206N pull at 0.5MPa. With a 210mm stroke, the 8mm rod has low side-load tolerance, so utilize an external guide rail to prevent rod bending. Remember that the fixed rubber bumper only softens end-of-stroke impacts; it does not hold the load if air pressure drops. For adjustable cushioning, look at the MBLC variant.
Upgrade checklist
- ✓ Order the MBL20X210U (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 MBL20X210U instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X210U FAQ
Yes, the MAL20X210U is discontinued. The exact drop-in replacement is the MBL20X210U, which offers the same 20mm bore, 210mm stroke, G1/8 port, and mounting accessories. You will just order the MBL equivalent.
The 20mm bore generates 157N push and 132N pull at 0.5MPa, 220N push at 0.7MPa, and a maximum of 32 kgf at 1.0 MPa. Because this specific SKU lacks an -S magnet, it cannot accommodate a position sensor.
