This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL20X190U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL20X190U 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 MAL20X190U
The AirTAC Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X190U is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 190mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL20X190U, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X190U
The AirTAC MAL20X190U is a discontinued compact double-acting aluminum mini round cylinder with a 20mm bore and 190mm stroke. It delivers 157N of push force and 132N of pull force at 0.5MPa. The exact drop-in replacement is the MBL20X190U, which matches the original bore, stroke, output force, G1/8 port, and U flat-end back cover.
This legacy MAL features threaded front and back covers, whereas the modern MBL replacement uses a riveted rolling-packed body. Because this specific SKU lacks an -S magnet, it cannot accept a position sensor. The bore uses a heterogeneous two-way grease-retaining seal and a self-lubricating front-cover bearing guide to support the Ø8mm carbon-steel rod with 20µm hard chrome plating.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL20X190U 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 MBL20X190U 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 MAL20X190U Is Used
PCB Depaneling Router
Cycles a routing blade at 190mm stroke to singulate printed circuit boards, utilizing the 157N push force to cleanly sever FR4 material without stressing surrounding components.
IC Test Handler Ejection
Pushes tested integrated circuits out of a tight socket in an automated handler, where the compact 20mm bore fits between dense tooling plates and the U flat cover mounts rigidly.
Small Parts Sorting Diverter
Actuates a small flap to deflect lightweight plastic caps on a conveyor, relying on the 30-800mm/s speed range to match high-throughput packaging line rates.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X190U with MBL20X190U
To replace the MAL20X190U, order the MBL20X190U. Verify your 20mm bore, 190mm stroke, G1/8 port, and default PT thread. The U designation indicates a flat-end rigid back cover. Since this SKU has no -S magnet, you cannot mount a sensor; if you need position detection, order an MBL20X190US and use the current CMSG, DMSG, or EMSG switches instead of the older CS1-M or DS1-M.
At 190mm stroke, the small Ø8mm rod has low side-load tolerance, so keep the load axially aligned or use an external guide to prevent rod bending. If sizing down, the smallest available bore is 20mm. If you need more force, stepping up to the 32mm bore yields 402N push at 0.5MPa. The MAL uses a fixed rubber bumper; if end-of-stroke energy is too high, step up to the MBLC for an adjustable air cushion. A plain MBL does not hold a load when air is lost, so add an external rod lock for fail-safe holding.
Upgrade checklist
- ✓ Order the MBL20X190U (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 MBL20X190U instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X190U FAQ
Yes, the MAL20X190U is discontinued. The exact drop-in replacement is the MBL20X190U, offering the same 20mm bore, 190mm stroke, 157N push force, G1/8 port, and U flat-end mounting. You simply order the MBL equivalent.
The 20mm bore provides 157N push and 132N pull at 0.5MPa, 220N push at 0.7MPa, and a maximum theoretical force of 32kgf at 1.0MPa. This specific SKU has no -S magnet, so it cannot accept a position sensor.
