This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL20X115SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL20X115SU 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 MAL20X115SU
The AirTAC Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X115SU is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 115mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL20X115SU, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X115SU
The AirTAC MAL20X115SU is a discontinued compact double-acting aluminum mini round cylinder with a 20mm bore and 115mm stroke. It delivers 157N of push force at 0.5MPa. AirTAC replaced this legacy unit with the MBL20X115SU, a drop-in alternative retaining the exact bore, stroke, output force, G1/8 port, and flat-end U back cover.
This SKU includes a built-in magnet (-S) for position sensing. On the MAL, this works with older CS1-M or DS1-M switches, but the MBL replacement shifts to the current CMSG, DMSG, or EMSG sensor family. The original MAL body uses threaded front and back covers, whereas the MBL upgrade features a riveted rolling-packed body. Both designs share the same internal architecture, including a heterogeneous two-way grease-retaining piston seal and a self-lubricating front-cover bearing guide that supports the 8mm carbon-steel rod with 20um hard-chrome plating.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL20X115SU 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 MBL20X115SU 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 MAL20X115SU Is Used
PCB Component Insertion
Drives a 157N push at 0.5MPa to seat connectors onto printed circuit boards, utilizing the 115mm stroke to clear surrounding tall capacitors during retraction.
Small Package Diverting
Actuates a routing flap on a compact packaging conveyor, where the flat-end U cover mounts rigidly to the frame and the -S magnet confirms flap position.
Lab Tube Ejection
Pushes capped sample tubes out of a centrifuge carousel, relying on the self-lubricating bearing guide to maintain smooth operation over thousands of cycles.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X115SU with MBL20X115SU
To replace the MAL20X115SU, order the MBL20X115SU. Verify your 20mm bore, 115mm stroke, G1/8 port, and default PT tapered thread. This SKU has a U flat-end back cover for rigid rear mounting and an -S magnet, meaning you must upgrade your CS1-M or DS1-M sensors to the CMSG, DMSG, or EMSG family. The MAL uses a fixed rubber bumper for end-of-stroke damping; if your application needs adjustable cushioning, step up to the MBLC variant on the current line.
For sizing context, stepping down to the nearest smaller bore is not applicable here as 20mm is the smallest available, but stepping up to the 25mm bore yields 245N of push force at 0.5MPa if you need more power. A plain MBL does not hold its load when air is lost, as the rod drifts without a lock. Since the 115mm stroke approaches the 300mm threshold, be mindful of side-load tolerance; the 8mm rod has low bending resistance, so use an external guide rail to prevent premature seal wear.
Upgrade checklist
- ✓ Order the MBL20X115SU (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 MBL20X115SU instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X115SU FAQ
Yes, the MAL20X115SU is discontinued. The exact drop-in replacement is the MBL20X115SU. It matches the 20mm bore, 115mm stroke, G1/8 port, and U flat-end cover. The main difference is the MBL uses a riveted rolling-packed body instead of threaded covers, and the -S magnet now requires CMSG, DMSG, or EMSG switches instead of the older CS1-M or DS1-M sensors.
At 0.5MPa, the 20mm bore provides 157N of push force and 132N of pull force. At 0.7MPa, the push force is 220N. The maximum theoretical force is 32kgf at 1.0MPa. It operates at speeds between 30 and 800mm/s.
