This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL20X140U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL20X140U 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 MAL20X140U
The AirTAC Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X140U is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 140mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL20X140U, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X140U
The AirTAC MAL20X140U is a discontinued compact double-acting aluminum mini round cylinder with a 20 mm bore and 140 mm stroke. It delivers 157 N of push force and 132 N of pull force at 0.5 MPa. The exact drop-in replacement is the MBL20X140U, matching the original bore, stroke, output force, G1/8 port, and flat-end rear cover.
This legacy MAL unit features threaded front and back covers, whereas the current MBL uses a riveted rolling-packed body. Because this specific SKU lacks the -S magnet option, it cannot accept a position sensor. The bore utilizes a heterogeneous two-way seal that retains grease, paired with a self-lubricating front-cover bearing guide to support the 8 mm carbon-steel rod.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL20X140U 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 MBL20X140U 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 MAL20X140U Is Used
PCB Depaneling Router
Actuates a routing blade to singulate 1.6 mm thick FR4 circuit boards, using the 157 N push force to cleanly sever the substrate without stressing adjacent SMD components.
Small Parts Ejector
Pushes lightweight plastic caps out of a molding cavity, relying on the 132 N pull force at 0.5 MPa to retract the 8 mm rod quickly within the 140 mm stroke envelope.
Connector Insertion Tool
Presses 1.27 mm pitch ribbon cable IDC connectors onto PCB headers in tight electronics assembly fixtures where the 20 mm aluminum body saves valuable space.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X140U with MBL20X140U
To replace the MAL20X140U, order the MBL20X140U. Verify your 20 mm bore, 140 mm stroke, G1/8 PT port, and the U flat-end back cover. Since this SKU has no -S magnet, it cannot support a sensor; if you need position detection on the new MBL, add the S option and migrate from the legacy CS1-M / DS1-M switches to the current CMSG / DMSG / EMSG family.
For sizing flexibility, stepping down to the 20 mm bore is the smallest available option, but stepping up to a 25 mm bore yields 245 N push force at 0.5 MPa. If your cycle requires adjustable end-cushioning rather than the fixed rubber bumper found here, specify the MBLC variant on the current line. Note that a plain cylinder does not hold its load when air is lost; the rod drifts, so an external rod lock or pilot-operated check valve is required for holding. At 140 mm stroke, the 8 mm rod is susceptible to bending under side-loads, so use an external guide rail to prevent premature seal wear.
Upgrade checklist
- ✓ Order the MBL20X140U (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 MBL20X140U instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X140U FAQ
Yes, the MAL20X140U is discontinued. The exact drop-in replacement is the MBL20X140U, which matches the 20 mm bore, 140 mm stroke, G1/8 port, and flat-end U cover. The MBL uses a riveted rolling-packed body instead of the threaded covers on the MAL, but the performance and mounting remain identical.
The 20 mm bore delivers a push force of 157 N and a pull force of 132 N at 0.5 MPa. At 0.7 MPa, the push force is 220 N. The maximum theoretical force is 32 kgf at 1.0 MPa. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor.
