This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL20X400-S-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL20X400-S-U 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 MAL20X400-S-U
The AirTAC Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X400-S-U is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 400mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL20X400-S-U, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X400-S-U
The AirTAC MAL20X400-S-U is a discontinued compact double-acting aluminum mini round cylinder with a 20mm bore and 400mm stroke. It delivers 157N of push force and 132N of pull force at 0.5MPa. AirTAC replaced this legacy unit with the MBL20X400-S-U, a true drop-in alternative retaining the exact same bore, stroke, output force, G1/8 port, and U flat-end rear cover.
This SKU includes a built-in magnet (-S) for position sensing. On the original MAL body—which uses threaded front and back covers—the magnet pairs with older CS1-M or DS1-M reed switches. When upgrading to the riveted rolling-packed MBL barrel, you must migrate to the current CMSG, DMSG, or EMSG sensor family. The 8mm carbon-steel rod relies on a self-lubricating front-cover bearing guide and a heterogeneous two-way seal that retains grease for prolonged cycle life.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL20X400-S-U 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 | — |

Where the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X400-S-U Is Used
PCB Conveyor Routing
Pushes printed circuit boards onto diverter arms within tight electronics assembly lines, utilizing the 157N push force and 400mm travel to clear adjacent machinery.
Small Parts Ejection
Ejects molded plastic caps from a thermoforming press into a collection chute, where the compact 20mm body fits between narrow tooling clearances.
Textile Yarn Guiding
Cycles a yarn tensioning gate back and forth across a 400mm span, relying on the U flat-end cover to hold the frame rigid against high-frequency vibration.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X400-S-U with MBL20X400-S-U
To replace the MAL20X400-S-U, order the MBL20X400-S-U. Confirm your 20mm bore, 400mm stroke, G1/8 port, and the default PT thread form. Retain the U flat-end back cover for rigid mounting, and note that the -S magnet requires switching from legacy CS1-M/DS1-M switches to modern CMSG/DMSG/EMSG sensors on the MBL. If you need adjustable end-of-stroke cushioning—which the fixed rubber bumper on this MAL lacks—step up to the MBLC variant.
For sizing flexibility, stepping down to the 12mm bore class is not available in this family, but stepping up to the 25mm bore yields 245N of push force at 0.5MPa if your payload increases. Because this 400mm stroke is quite long for an 8mm rod, side-load tolerance is very low. You must use an external guide rail to prevent rod bending, as the rubber bumper only softens the stroke end and does not lock the load when air pressure is lost.
Upgrade checklist
- ✓ Order the MBL20X400-S-U (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 MBL20X400-S-U instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X400-S-U FAQ
Yes, the MAL20X400-S-U is discontinued. The exact drop-in replacement is the MBL20X400-S-U. It matches the 20mm bore, 400mm stroke, G1/8 port, U flat-end cover, and -S magnet. The main change is the body construction: the MAL uses threaded covers while the MBL uses a riveted rolling-packed barrel.
At 0.5 MPa it provides 157N push and 132N pull; at 0.7 MPa it provides 220N push, with a theoretical maximum of 32 kgf at 1.0 MPa. The -S magnet on the MAL works with CS1-M and DS1-M switches, but the MBL replacement requires CMSG, DMSG, or EMSG sensors.
