This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement MBL20X150SU, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 MAL20X150-S-U
The AirTAC MAL20 Aluminum Alloy Mini Cylinder MAL20X150-S-U is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 150mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the direct replacement is the MBL20X150-S-U, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X150-S-U
The AirTAC MAL20X150-S-U is a discontinued compact double-acting aluminum mini round cylinder with a 20mm bore and 150mm stroke. It delivers 157N of push force and 132N of pull force at 0.5 MPa. AirTAC replaced this legacy unit with the MBL20X150-S-U, a direct alternative that matches the exact bore, stroke, output force, G1/8 port, and flat-end U back cover.
This SKU includes a built-in magnet (-S) for position sensing. On the MAL, this magnet interfaces with the older CS1-M or DS1-M switches, whereas the MBL replacement transitions to the current CMSG, DMSG, or EMSG sensor families. Structurally, the MAL uses threaded front and back covers on the barrel, while the newer MBL features a riveted rolling-packed body. The 8mm carbon-steel rod has a 20um hard-chrome plating, and the self-lubricating front-cover bearing guide supports a heterogeneous two-way seal that retains grease.

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 MAL20X150-S-U Is Used
PCB Depaneling Router
Drives a small routing blade to cut individual circuit boards from a panel, using the 150mm stroke to clear the fixture during tool changes.
IC Test Handler Ejector
Ejects tested integrated circuits from a socket with 157N of push force at 0.5 MPa, fitting within the tight spatial envelope of semiconductor test equipment.
Small-Part Diverter Gate
Actuates a lightweight aluminum flap to sort small plastic housings on a conveyor belt, relying on the U flat-end cover for rigid rear mounting.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X150-S-U with MBL20X150-S-U
To replace the MAL20X150-S-U, order the MBL20X150-S-U to retain the 20mm bore, 150mm stroke, G1/8 port, and U flat-end back cover. If your application allows a smaller footprint, the neighboring 20mm bore is the smallest available option, so sizing down is not possible. Sizing up to the 32mm bore increases the 0.5 MPa push force to 402N. Because this unit has a 150mm stroke, the 8mm rod has low side-load tolerance, requiring an external guide to prevent rod bending. Note that the fixed rubber bumper softens end-of-stroke impacts but does not hold the load if air pressure drops; for position holding, use an external rod lock. If an adjustable air cushion is required, step up to the MBLC variant on the current line.
Upgrade checklist
- ✓ Order the MBL20X150-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 MBL20X150-S-U instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X150-S-U FAQ
Yes, the MAL series is end-of-life. The direct replacement is the MBL20X150-S-U, which matches the 20mm bore, 150mm stroke, G1/8 port, U back cover, and -S magnet. You will need to upgrade your sensors from the older CS1-M/DS1-M to the CMSG/DMSG/EMSG family.
At 0.5 MPa, the push force is 157N and the pull force is 132N. At 0.7 MPa, the push force is 220N. The maximum theoretical force is 32 kgf at 1.0 MPa.
