This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL20X225U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL20X225U 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 MAL20X225U
The AirTAC Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X225U is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 225mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL20X225U, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X225U
The AirTAC MAL20X225U is a discontinued compact double-acting aluminum mini round cylinder. It delivers 157 N of push force and 132 N of pull force at 0.5 MPa. The exact drop-in replacement is the MBL20X225U, matching the 20 mm bore, 225 mm stroke, G1/8 port, and U flat-end back cover.
This legacy unit features a fixed rubber bumper and a heterogeneous two-way seal that retains grease. The original MAL body uses threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed body. Because this specific SKU lacks the -S magnet option, it cannot accept a position sensor.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL20X225U 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 MBL20X225U 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 MAL20X225U Is Used
PCB Router Ejection
Uses the 157 N push force at 0.5 MPa to eject cut printed circuit boards from a routing machine spindle area.
Small Parts Diverting
Actuates a lightweight flap in a packaging conveyor to divert small plastic enclosures into a sorting bin.
Pick-and-Place Z-Axis
Provides 225 mm of vertical travel for a compact vacuum gripper moving delicate electronic components.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X225U with MBL20X225U
To replace the MAL20X225U, order the MBL20X225U. Confirm your 20 mm bore, 225 mm stroke, G1/8 port, and PT thread form. The rigid U flat-end back cover mounts directly to a flat surface. If you need to step down, the 20 mm bore is the smallest available, so you must step up to the 25 mm bore (which provides 245 N push at 0.5 MPa). If you require adjustable cushioning rather than the fixed rubber bumper, specify the current-line MBLC.
With a 225 mm stroke driven by an 8 mm rod, side-load tolerance is low. Use an external guide to prevent rod bending. A plain cylinder does not hold its position when air is lost; install a pilot-operated check valve if load holding is required.
Upgrade checklist
- ✓ Order the MBL20X225U (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 MBL20X225U instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X225U FAQ
Yes, the MAL20X225U is discontinued. The exact drop-in replacement is the MBL20X225U, which matches the 20 mm bore, 225 mm stroke, output force, G1/8 port, and U flat-end mounting.
At 0.5 MPa it provides 157 N push and 132 N pull. At 0.7 MPa it provides 220 N push. The maximum theoretical force is 32 kgf at 1.0 MPa.
