This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X4CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X4CA 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 MAL25 Aluminum Alloy Mini Cylinder MAL25X4CA
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X4CA is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 4mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X4CA, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X4CA
The AirTAC MAL25X4CA is a discontinued compact double-acting aluminum mini round cylinder. Delivering 245 N of push force at 0.5 MPa, this 25 mm bore unit features a 4 mm stroke. The exact drop-in replacement is the MBL25X4CA, which matches the original bore, stroke, output force, G1/8 port, and CA pivot mounting.
This legacy MAL features threaded front and back covers, whereas the current MBL uses a riveted rolling-packed body. The rod relies on a heterogeneous two-way seal that retains grease alongside a self-lubricating front-cover bearing guide. Because this specific SKU lacks an -S magnet, it cannot accept a position sensor.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X4CA carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | — |
| Max (@1.0 MPa) | 50 kgf | |
The MBL25X4CA 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 MAL25 Aluminum Alloy Mini Cylinder MAL25X4CA Is Used
Valve Gate Poppet
Provides 245 N push at 0.5 MPa to actuate small pneumatic valve poppets in micro-fluidic dispensing heads over a 4 mm stroke.
PCB Edge Clamp
Secures printed circuit boards during surface mount reflow with a rapid 4 mm retraction, utilizing the 206 N pull force.
Micro-Pipette Drive
Drives a multi-channel pipette head in lab automation, where the CA pivot absorbs slight mounting offsets during the short 4 mm travel.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X4CA with MBL25X4CA
To replace the MAL25X4CA, order the MBL25X4CA. Confirm the 25 mm bore, 4 mm stroke, PT thread, and CA pivot back cover are retained. Since this unit has no -S magnet, it cannot support a sensor; if detection is needed, step up to an MBL25X4SCA and note the MBL uses CMSG/DMSG/EMSG switches instead of the old CS1-M/DS1-M. If you need to adjust force, step down to the 20 mm bore offering 157 N push, or step up to the 32 mm bore providing 402 N. The MAL uses a fixed rubber bumper, so for adjustable cushioning, look to the MBLC variant. A plain cylinder does not hold a load when air is lost; add an external rod lock for vertical holding.
Upgrade checklist
- ✓ Order the MBL25X4CA (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 MBL25X4CA instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X4CA FAQ
Yes, the AirTAC MAL25X4CA is discontinued. The exact drop-in replacement is the MBL25X4CA, offering the same 25 mm bore, 4 mm stroke, 50 kgf max force, G1/8 port, and CA pivot mounting.
At 0.5 MPa, the push force is 245 N and the pull force is 206 N. At 0.7 MPa, the push force is 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa.
