This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL20X25SCAH — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL20X25SCAH 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 MAL20X25SCAH
The AirTAC Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X25SCAH is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 25mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL20X25SCAH, which matches its bore, stroke, force and mounting.

About the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X25SCAH
The AirTAC MAL20X25SCAH is a discontinued double-acting aluminum mini round cylinder with a 20mm bore and 25mm stroke. It delivers 157N push and 132N pull at 0.5 MPa. AirTAC replaced this legacy unit with the MBL20X25SCAH, a drop-in alternative retaining the exact G1/8 port, M8x1.25 rod thread, and CA pivot mounting.
This SKU includes a magnetic piston (-S) for position detection. The older MAL body uses threaded front and back covers, whereas the current MBL features a riveted rolling-packed barrel. For sensing, the original MAL works with CS1-M or DS1-M switches, while the MBL successor requires CMSG, DMSG, or EMSG sensors. The internal piston relies on a heterogeneous two-way seal that retains grease for long service life.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X25SCAH Technical Specifications

| Stroke | 25 mm |
| Acting type | Double acting |
| Port size | G1/8 |
| Rod thread | M8×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.1 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Fixed rubber bumper |
| Max standard stroke | Up to 500 mm |
Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL20X25SCAH 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 MBL20X25SCAH 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 MAL20X25SCAH Is Used
PCB Routing Head
Drives a small routing head across printed circuit boards, using the 157N push force to cleanly sever trace connections in tight electronics assembly cells.
Pharmacy Pill Dispenser
Pushes individual blister packs into a checkout chute, where the compact 20mm body fits easily between storage lanes and the short 25mm stroke prevents crushing the product.
Lab Tube Sorter
Uses the CA pivot bracket to swing sample tubes into a centrifuge carousel, relying on the magnetic piston to confirm arm extension via a DS1-M switch.
Replacing the Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X25SCAH with MBL20X25SCAH
To replace the MAL20X25SCAH, order the MBL20X25SCAH. Confirm the 20mm bore, 25mm stroke, PT thread, CA pivot back cover, and the magnetic piston. Because the -S magnet is present, note that your existing CS1-M or DS1-M switches must be upgraded to CMSG, DMSG, or EMSG sensors to match the new MBL body. The CA clevis allows the cylinder to swing on a pin, which is essential for arcing motion paths.
For sizing flexibility, stepping down is not an option as 20mm is the smallest available bore. Stepping up to the 32mm bore yields 402N of push force at 0.5 MPa if your application requires more power. This cylinder uses a fixed rubber bumper rather than an adjustable cushion; if you need end-of-stroke deceleration, look at the MBLC variant on the current line. A plain cylinder does not hold its load when air pressure is lost, so add an external rod lock for vertical applications.
Upgrade checklist
- ✓ Order the MBL20X25SCAH (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 MBL20X25SCAH instead of this discontinued model.
Airtac MAL20 Aluminum Alloy Mini Cylinder MAL20X25SCAH FAQ
Yes, the MAL20X25SCAH is discontinued. The exact drop-in replacement is the MBL20X25SCAH, which matches the 20mm bore, 25mm stroke, G1/8 port, and CA pivot mounting. You must upgrade your position sensors from the old CS1-M or DS1-M to the newer CMSG, DMSG, or EMSG family.
At 0.5 MPa, the push force is 157N and the pull force is 132N. At 0.7 MPa, the push force increases to 220N. The maximum theoretical force is 32 kgf at 1.0 MPa operating pressure.
