This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL20X275SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL20X275SU 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 MAL20X275SU
The AirTAC Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X275SU is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 275mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL20X275SU, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X275SU
The AirTAC MAL20X275SU is a discontinued compact double-acting aluminum mini round cylinder with a 20mm bore and 275mm stroke. It delivers 157N push and 132N pull at 0.5MPa, fitting tight spaces where low-profile actuation is needed. The exact drop-in replacement is the MBL20X275SU, matching the bore, stroke, force, G1/8 port, and U flat-end back cover perfectly.
This legacy SKU features a built-in magnet (-S) for position detection with older CS1-M or DS1-M switches. The newer MBL replacement requires CMSG, DMSG, or EMSG sensors. Unlike the riveted rolling-packed body of the MBL, the original MAL uses threaded front and back covers. The piston relies on a heterogeneous two-way grease-retaining seal, while the carbon-steel rod has 20um hard-chrome plating for wear resistance.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X275SU Technical Specifications

| 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 MBL20X275SU 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 MBL20X275SU 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 MAL20X275SU Is Used
PCB Conveyor Routing
Pushes populated PCB assemblies across a 275mm routing lane in electronics assembly lines using 157N of push force at 0.5MPa.
Carton Flap Breaker
Breaks minor carton end flaps on compact packaging machines where the 132N pull stroke retracts an 8mm rod cleanly into a tight footprint.
Small Part Ejector
Ejects machined plastic bushings from a lathe chuck using the U flat-end cover for rigid, straight-line mounting without arcing.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X275SU with MBL20X275SU
To replace the MAL20X275SU, order the MBL20X275SU and update your sensor inventory from CS1-M/DS1-M to the CMSG/DMSG/EMSG family. Confirm the PT port thread and the U flat-end rigid back cover match your existing mounting layout. If you need an adjustable air cushion to soften the 275mm stroke ends, step up to the MBLC variant, as the MAL only has a fixed rubber bumper.
For sizing flexibility, stepping down to a 16mm bore offers lower force, while stepping up to a 25mm bore yields 245N push at 0.5MPa. At 275mm, the 8mm rod has low side-load tolerance, so use an external guide or pivot to prevent rod bending. A plain MAL/MBL does not hold a load when air is lost; add an external rod lock for position holding.
Upgrade checklist
- ✓ Order the MBL20X275SU (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 MBL20X275SU instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X275SU FAQ
Yes, the MAL20X275SU is discontinued. The exact drop-in replacement is the MBL20X275SU, offering the same 20mm bore, 275mm stroke, force, G1/8 port, and U flat-end cover. You must only update your position sensors from the legacy CS1-M/DS1-M to the current CMSG/DMSG/EMSG switches.
The 20mm bore provides a push force of 157N and a pull force of 132N at 0.5MPa. At 0.7MPa, the push force is 220N. The maximum theoretical force is 32kgf at 1.0MPa.
