This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL20X100-S-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL20X100-S-U 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 MAL20X100-S-U
The AirTAC Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X100-S-U is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 100mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL20X100-S-U, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X100-S-U
The AirTAC MAL20X100-S-U is a discontinued compact double-acting aluminum mini round cylinder. Designed for small-part automation, it delivers a 157 N push force at 0.5 MPa (132 N pull) across its 100 mm stroke. The exact drop-in replacement is the MBL20X100-S-U, matching the 20 mm bore, G1/8 port, and U flat-end back cover for a seamless retrofit.
This legacy SKU features a built-in -S magnet for position sensing. On the original MAL body, which uses threaded front and back covers, this magnet pairs with the older CS1-M and DS1-M switches. When upgrading to the riveted rolling-packed MBL20X100-S-U, you must migrate to the current CMSG, DMSG, or EMSG sensor families. The 8 mm carbon-steel rod relies on a self-lubricating front-cover bearing guide and a heterogeneous two-way seal that retains grease for long service life.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL20X100-S-U 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 MBL20X100-S-U 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 MAL20X100-S-U Is Used
PCB Push-off Station
Uses the 157 N push force at 0.5 MPa to safely eject populated printed circuit boards from an SMT testing fixture without damaging delicate traces.
Carton Flap Tucking
Cycles the 100 mm stroke to tuck minor flaps on small pharmaceutical cartons on a high-speed packaging line prior to glue application.
Vial Sorting Diverter
Actuates a small pneumatic gate to route empty glass vials into an inspection carousel, relying on the compact 20 mm body to fit tight machine guards.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X100-S-U with MBL20X100-S-U
To replace the MAL20X100-S-U, order the MBL20X100-S-U. Confirm your 100 mm stroke, PT thread, and the U flat-end back cover. Because this SKU includes the -S magnet, plan to swap your legacy CS1-M or DS1-M reed switches for CMSG, DMSG, or EMSG sensors on the new MBL body. The fixed rubber bumper absorbs end-of-stroke impact; if your application requires adjustable air cushioning, step up to the current-line MBLC variant.
For sizing, the 20 mm bore provides 157 N push at 0.5 MPa. If you need less force, there is no smaller standard MAL bore, so look to alternative compact lines. If you need more power, step up to the 25 mm bore, which yields 245 N push at 0.5 MPa. Since this is a 100 mm stroke on an 8 mm rod, side-load tolerance is low; use an external guide to prevent rod bending. Note that a plain cylinder drifts when air is lost, so add an external rod lock for position holding.
Upgrade checklist
- ✓ Order the MBL20X100-S-U (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 MBL20X100-S-U instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X100-S-U FAQ
Yes, the MAL20X100-S-U is discontinued. The exact drop-in replacement is the MBL20X100-S-U, which matches the 20 mm bore, 100 mm stroke, G1/8 port, U flat-end cover, and -S magnet. You must upgrade your sensors from the old CS1-M or DS1-M switches to the CMSG, DMSG, or EMSG family.
At 0.5 MPa, the push force is 157 N and the pull force is 132 N. At 0.7 MPa, the push force is 220 N. The maximum theoretical force is 32 kgf at 1.0 MPa.
