This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL20X230U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL20X230U 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 MAL20X230U
The AirTAC Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X230U is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 230mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL20X230U, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X230U
The AirTAC MAL20X230U is a discontinued compact double-acting aluminum mini round cylinder. It features a 20mm bore and 230mm stroke, delivering 157N push and 132N pull at 0.5 MPa. The exact drop-in replacement is the MBL20X230U, matching the bore, stroke, output force, G1/8 port, and U flat-end back cover for a seamless retrofit.
This legacy unit features threaded front and back covers, whereas the modern MBL utilizes a riveted rolling-packed body. The 8mm carbon-steel rod has 20um hard chrome plating, and because this SKU lacks the -S magnet, it cannot accept a position sensor. A fixed rubber bumper absorbs end-of-stroke impact, but it will not hold a load if air pressure drops.

| Rod thread | M8×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.1 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL20X230U 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 MBL20X230U 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 MAL20X230U Is Used
PCB Shuttle Gate
Cycles a 230mm stroke to divert bare printed circuit boards between SMT inspection lanes using 157N of push force at 0.5 MPa.
Wafer Cassette Ejector
Pushes semiconductor wafer cassettes out of a load port hood, relying on the U flat-end back cover for rigid, straight-line ejection.
Parts Carton Diverter
Actuates a lightweight pneumatic flap to sort small packaged electronics boxes on a tight-space conveyor without ISO 15552 bulk.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X230U with MBL20X230U
To replace the MAL20X230U, order the MBL20X230U and verify your 8mm rod-end M8x1.25 thread and PT port connections. If you need position sensing on the new unit, add the -S option, noting the MBL switches to the modern CMSG/DMSG/EMSG family from the legacy CS1-M/DS1-M. If you need an adjustable air cushion instead of the fixed rubber bumper, specify the MBLC series.
For sizing flexibility, stepping down to the 32mm bore yields 402N push at 0.5 MPa, while stepping down to the 20mm bore provides 157N. Note that a plain MBL does not hold position upon air loss; install an external rod lock for vertical loads. At 230mm stroke, the 8mm rod has low side-load tolerance, so use a U flat-end rigid mount or an external guide to prevent rod bending.
Upgrade checklist
- ✓ Order the MBL20X230U (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 MBL20X230U instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X230U FAQ
Yes, the MAL20X230U is discontinued. The exact drop-in replacement is the MBL20X230U, which shares the same 20mm bore, 230mm stroke, G1/8 port, U flat-end cover, and mounting accessories.
At 0.5 MPa, it provides 157N push and 132N pull; at 0.7 MPa it yields 220N push, with a maximum theoretical force of 32 kgf at 1.0 MPa. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor.
