This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X420CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X420CA 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 MAL25X420CA
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X420CA is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 420mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X420CA, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X420CA
The AirTAC MAL25X420CA is a discontinued compact double-acting aluminum mini round cylinder with a 25mm bore and 420mm stroke. It delivers 245N of push force at 0.5MPa and features a G1/8 port. As a legacy component, it is replaced by the MBL25X420CA, a drop-in alternative that matches the exact bore, stroke, output force, port size, and CA mounting accessory.
This legacy MAL unit relies on threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed body. The CA back cover acts as a pivot clevis, swinging on a pin to absorb arcing rod movements. Because this SKU lacks an -S magnet, it cannot accept a position sensor. The internal piston uses a heterogeneous two-way seal that retains grease, and the carbon-steel rod has 20um hard chrome plating to resist wear.

| Acting type | Double acting |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| 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 |

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X420CA 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 MBL25X420CA 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 MAL25X420CA Is Used
Pouch Spreader
Drives a swinging arm to open packaging film webs on a vertical form-fill-seal machine, using the 245N push force and 420mm travel to clear the sealing jaws.
PCB Shuttle
Moves populated circuit boards between an SMT pick-and-place station and a reflow oven, where the CA pivot clevis accommodates the slight arcing motion of the transfer arm.
Tote Pusher
Ejects filled plastic totes from a palletizing cell, relying on the 420mm stroke to fully clear the conveyor lane before the next box arrives.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X420CA with MBL25X420CA
To replace the MAL25X420CA, order the MBL25X420CA and confirm your PT port thread and CA pivot back cover. If you need position sensing, note that this specific legacy unit has no magnet and cannot take a sensor; you must specify an -S code on the MBL order, which will require upgrading to CMSG, DMSG, or EMSG switches instead of the older CS1-M or DS1-M. The MAL uses a fixed rubber bumper; if your load requires adjustable cushioning, step up to the MBLC variant on the current line.
For sizing flexibility, you can step down to the 20mm bore (157N push at 0.5MPa) for lighter loads, or step up to the 32mm bore (402N push at 0.5MPa) for higher force. At 420mm of stroke, the 10mm rod is highly susceptible to bending under side-loads; the CA clevis helps, but you should add an external guide rail. A plain bumper does not hold a load when air is lost, so install an external rod lock or pilot-operated check valve for fail-safe positioning.
Upgrade checklist
- ✓ Order the MBL25X420CA (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 MBL25X420CA instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X420CA FAQ
Yes, the MAL25X420CA is discontinued. The exact drop-in replacement is the MBL25X420CA, which matches the 25mm bore, 420mm stroke, G1/8 port, and CA pivot mounting. You simply order the MBL25X420CA as a direct replacement.
The 25mm bore provides 245N push and 206N pull at 0.5MPa, 343N push at 0.7MPa, and a maximum theoretical force of 50kgf at 1.0MPa. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor.
