This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL20X105U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL20X105U 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 MAL20X105U
The AirTAC Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X105U is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 105mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL20X105U, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X105U
The AirTAC MAL20X105U is a discontinued compact double-acting aluminum mini round cylinder with a 20mm bore and 105mm stroke. It delivers 157N push and 132N pull at 0.5 MPa. Because this legacy series is end-of-life, the direct drop-in replacement is the MBL20X105U, which matches the exact bore, stroke, output force, G1/8 port, and U flat-end rear cover.
The original MAL body used threaded front and back covers, whereas the current MBL upgrade features a riveted rolling-packed body for equally robust performance. This specific SKU lacks a -S magnet, meaning it cannot support a position sensor. Additionally, the bore uses a heterogeneous two-way grease-retaining seal paired with a self-lubricating front-cover bearing guide to ensure long service life.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL20X105U 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 MBL20X105U 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 MAL20X105U Is Used
PCB Depaneling Router
Provides the 157N push at 0.5 MPa needed to drive a small cutting blade through assembled printed circuit boards without stressing surrounding components.
IC Test Socket Actuator
Uses the precise 105mm stroke to lower an integrated circuit test probe onto a semiconductor package with consistent 132N retraction force.
Small Parts Ejector
Pushes lightweight plastic injection-molded housings out of a tight mold cavity using the compact 20mm aluminum body in confined machine spaces.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X105U with MBL20X105U
To replace the MAL20X105U, order the MBL20X105U. Confirm your 105mm stroke requirement, the G1/8 PT port thread, and the U flat-end rigid back cover. Because this SKU has no -S magnet, it cannot accept a sensor; if you need position detection, order an MBL20X105US and note that the MBL uses the current CMSG/DMSG/EMSG switches rather than the legacy CS1-M/DS1-M. The MAL uses a fixed rubber bumper; if your application requires adjustable end-of-stroke cushioning, step up to the MBLC variant on the current line.
For sizing flexibility, stepping down to the next available bore is not an option as 20mm is the smallest mini round size. Stepping up to the 25mm bore yields a higher 245N push force at 0.5 MPa. A plain cylinder does not hold its load when air is lost; the rod will drift, so use an external rod lock for vertical loads. At 105mm stroke, the 8mm rod has low side-load tolerance, so avoid direct lateral forces.
Upgrade checklist
- ✓ Order the MBL20X105U (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 MBL20X105U instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X105U FAQ
Yes, the MAL20X105U is discontinued. The exact drop-in replacement is the AirTAC MBL20X105U. It offers the same 20mm bore, 105mm stroke, 157N push force at 0.5 MPa, G1/8 port, and U flat-end back cover. The MBL uses a riveted body instead of the threaded covers found on the MAL.
The 20mm bore provides 157N push and 132N pull at 0.5 MPa, 220N push at 0.7 MPa, and a maximum theoretical force of 32 kgf at 1.0 MPa. It uses a G1/8 port, an 8mm rod with an M8x1.25 thread, and operates between 0.1-1.0 MPa.
