This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL20X270SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL20X270SU 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 MAL20X270SU
The AirTAC Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X270SU is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 270mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL20X270SU, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X270SU
The AirTAC MAL20X270SU is a discontinued compact double-acting aluminum mini round cylinder with a 20mm bore and 270mm stroke. It delivers 157N of push force and 132N of pull force at 0.5MPa, utilizing a G1/8 port and an 8mm hard-chrome plated carbon-steel rod. Because this legacy series has reached end-of-life, AirTAC engineered the MBL20X270SU as the exact drop-in replacement, matching the bore, stroke, output force, port size, and U flat-end back cover for a seamless retrofit.
This specific SKU features a U flat-end back cover for rigid rear mounting and a built-in magnet (-S) for position detection. Two non-obvious engineering details define this unit: the piston relies on a heterogeneous two-way seal that retains grease for long-term friction reduction, and the front cover integrates a self-lubricating bearing guide to support the small 8mm rod. Note that the original threaded front and back covers on the MAL differ from the riveted rolling-packed body found on the modern MBL. Furthermore, the -S magnet on this legacy unit interfaces with older CS1-M or DS1-M reed switches, whereas upgrading to the MBL20X270SU requires the current CMSG, DMSG, or EMSG sensor family.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL20X270SU 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 MBL20X270SU 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 MAL20X270SU Is Used
PCB Depaneling Router
Provides the 157N push force at 0.5MPa needed to drive a 270mm stroke that separates routed printed circuit boards in low-vibration electronics assembly.
IC Test Handler Ejection
Actuates the 270mm travel to push tested integrated circuits out of sockets, using the U flat-end cover for rigid frame mounting and the -S magnet for cycle counting.
Small Parts Tray Indexing
Shifts lightweight packaging trays along a conveyor using the 8mm hard-chrome plated rod, relying on the self-lubricating bearing guide to handle the 270mm extension.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X270SU with MBL20X270SU
To replace the MAL20X270SU, order the MBL20X270SU and verify your 20mm bore, 270mm stroke, G1/8 port, and PT thread form. You must also account for the U flat-end back cover and the -S magnet. When upgrading, the -S magnet on the MAL works with CS1-M and DS1-M switches, but the MBL replacement mandates a switch to the CMSG, DMSG, or EMSG sensor family. If you need to adjust your sizing, stepping down to the 32mm bore yields a stronger 402N push at 0.5MPa, while no smaller standard bore exists below 20mm in this mini round family.
Because the 270mm stroke is 300mm or under, side-load risks are moderate but present given the small 8mm rod diameter; an external guide rail is recommended to prevent rod bending. This plain cylinder does not hold its position or load when air pressure is lost, as the rod will drift, so an external rod lock or pilot-operated check valve is necessary for fail-safe load holding. The MAL uses a fixed rubber bumper, not an adjustable cushion; if end-of-stroke impact is an issue, consider the MBLC variant on the current line for adjustable air cushioning.
Upgrade checklist
- ✓ Order the MBL20X270SU (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 MBL20X270SU instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X270SU FAQ
Yes, the MAL20X270SU is discontinued. The exact drop-in replacement is the MBL20X270SU, which shares the identical 20mm bore, 270mm stroke, 157N push force, G1/8 port, and U flat-end back cover. You simply order the MBL20X270SU, though you must upgrade your sensors from the older CS1-M/DS1-M switches to the CMSG/DMSG/EMSG family.
The 20mm bore double-acting cylinder provides 157N push and 132N pull at 0.5MPa, 220N push at 0.7MPa, and a maximum theoretical force of 32kgf at 1.0MPa. It operates at 0.1-1.0MPa with a speed range of 30-800mm/s and uses a fixed rubber bumper rather than an adjustable cushion.
