This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL20X230SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL20X230SU 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 MAL20X230SU
The AirTAC Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X230SU 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 MBL20X230SU, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X230SU
The AirTAC MAL20X230SU is a discontinued double-acting aluminum mini round cylinder. As a compact 20mm bore unit, it delivers 157N push and 132N pull at 0.5MPa. It features a 230mm stroke, an 8mm carbon-steel rod with 20um hard chrome plating, and a U flat-end back cover. AirTAC ended this line, so the direct drop-in replacement is the MBL20X230SU, which matches the bore, stroke, 32kgf max force, G1/8 port, and U cover exactly.
This SKU includes a -S magnet for position sensing. On the legacy MAL body, which uses threaded front and back covers, the magnet works with older CS1-M or DS1-M switches. When upgrading to the riveted rolling-packed MBL20X230SU, you must update your sensors to the current CMSG, DMSG, or EMSG families. The internal piston relies on a heterogeneous two-way seal that retains grease, while the self-lubricating front-cover bearing guide supports the rod.

| Acting type | Double acting |
| Port size | G1/8 |
| 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 |
| Cushion | Fixed rubber bumper |
| Max standard stroke | Up to 500 mm |
Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL20X230SU 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 MBL20X230SU 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 MAL20X230SU Is Used
PCB Depaneling Router
Drives a cutting blade at 157N push to singulate printed circuit boards, utilizing the 230mm stroke to clear the fixture during tool changes.
Carton Erector Arm
Folds minor flaps on small packaging boxes in tight spaces, relying on the U flat-end cover for rigid frame mounting and the 8mm hard-chrome rod for wear resistance.
Pallet Diverter Gate
Actuates a routing flap at 132N pull to sort small product pallets, using the -S magnet and CS1-M sensor to confirm the gate is fully retracted before the belt runs.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X230SU with MBL20X230SU
To replace the MAL20X230SU, order the MBL20X230SU. Verify your 20mm bore, 230mm stroke, PT thread, and U flat-end back cover. Because this SKU has the -S magnet, plan to swap your legacy CS1-M/DS1-M switches for CMSG/DMSG/EMSG sensors on the new riveted MBL body. If you need an adjustable air cushion rather than the fixed rubber bumper found here, step up to the MBLC variant.
For sizing, step down to the smaller bore option if less force is needed, or step up to the 25mm bore (245N push at 0.5MPa) if your load requires more power. At 230mm of travel, the 8mm rod has low side-load tolerance; use an external guide rail to prevent rod bending. A plain bumper does not hold the load when air is lost, so add an external rod lock for vertical safety.
Upgrade checklist
- ✓ Order the MBL20X230SU (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 MBL20X230SU instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X230SU FAQ
Yes, the MAL20X230SU is discontinued. The exact drop-in replacement is the MBL20X230SU, which offers the same 20mm bore, 230mm stroke, 32kgf max force, G1/8 port, and U flat-end cover. You must update your sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG.
At 0.5MPa it provides 157N push and 132N pull; at 0.7MPa it provides 220N push; the maximum theoretical force is 32kgf at 1.0MPa. It operates on filtered air at 0.1-1.0MPa, runs at 30-800mm/s, and uses a fixed rubber bumper.
