This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL20X120SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL20X120SU 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 MAL20X120SU
The AirTAC Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X120SU is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 120mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL20X120SU, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X120SU
The AirTAC MAL20X120SU is a discontinued double-acting aluminum mini round cylinder with a 20mm bore and 120mm stroke. It delivers 157N of push force and 132N of pull force at 0.5MPa. AirTAC replaced this legacy unit with the MBL20X120SU, a drop-in alternative retaining the exact same G1/8 port, M8x1.25 rod thread, and U flat-end rear cover. This compact actuator uses a fixed rubber bumper for end-of-stroke damping rather than an adjustable cushion.
This specific SKU includes a built-in magnet (-S) for position detection. On the original MAL body—which features threaded front and back covers—the magnet pairs with older CS1-M or DS1-M switches. The modern MBL20X120SU replacement transitions to a riveted rolling-packed body and requires the current CMSG, DMSG, or EMSG sensor families. The piston relies on a heterogeneous two-way seal that retains grease, gliding on a self-lubricating front-cover bearing around a hard-chrome plated carbon-steel rod.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL20X120SU 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 MBL20X120SU 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 MAL20X120SU Is Used
PCB Depaneling Ejector
Pushes singulated circuit boards out of a routing fixture with 157N of force at 0.5MPa, fitting easily into dense electronics assembly machinery.
Pharmacy Blister Cartoner
Transfers blister packs into cardboard cartons over a 120mm stroke, where the compact 20mm body avoids clashing with adjacent packaging lanes.
Microplate Shuttle Actuator
Moves 96-well microplates between liquid handling stations, relying on the U flat-end cover for rigid, non-pivoting alignment in tight lab automation spaces.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X120SU with MBL20X120SU
To replace the MAL20X120SU, order the MBL20X120SU. Confirm your 20mm bore, 120mm stroke, PT thread, and the rigid U flat-end back cover. Because this SKU has the -S magnet, you must upgrade your position sensing: the legacy CS1-M and DS1-M switches will not fit the MBL body, so select current CMSG, DMSG, or EMSG sensors. If your application requires adjustable air cushioning instead of the standard fixed rubber bumper, step up to the MBLC20 series on the current line.
For sizing flexibility, stepping down to the 20mm bore is the minimum available, but you can step up to a 25mm bore (245N push at 0.5MPa) if you need more force. At 120mm of travel, side-load tolerance is low due to the 8mm rod diameter; use an external guide rail to prevent rod bending. Remember that a plain MAL or MBL cylinder does not hold its load when air pressure drops—the rod will drift unless you add an external pilot-operated check valve.
Upgrade checklist
- ✓ Order the MBL20X120SU (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 MBL20X120SU instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X120SU FAQ
Yes, the MAL20X120SU is discontinued. The exact drop-in replacement is the MBL20X120SU. It matches the 20mm bore, 120mm stroke, G1/8 port, and U flat-end back cover. You must update your sensors because the MAL -S magnet uses CS1-M/DS1-M switches, while the MBL uses CMSG/DMSG/EMSG switches.
At 0.5MPa, the push force is 157N and the pull force is 132N. At 0.7MPa, the push force increases to 220N. The maximum theoretical force is 32kgf at 1.0MPa. The cylinder operates at 0.1-1.0MPa with a speed range of 30-800mm/s.
