This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X400-CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X400-CM 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 MAL25X400-CM
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X400-CM is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 400mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X400-CM, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X400-CM
The AirTAC MAL25X400-CM is a discontinued double-acting aluminum mini round cylinder with a 25 mm bore and 400 mm stroke, delivering 245 N of push force at 0.5 MPa. The exact drop-in replacement is the MBL25X400-CM, which matches the bore, stroke, output force, G1/8 port, and CM round-end mounting. This legacy model features a carbon-steel rod with a 20 um hard-chrome plating and a heterogeneous two-way seal that retains grease for long service life.
Because this SKU lacks an -S magnet, it cannot accept a position sensor. The original MAL body uses threaded front and back covers, whereas the current MBL replacement features a riveted rolling-packed body for equally robust performance. The MAL relies on a fixed rubber bumper, so if your application requires adjustable end-cushioning, you should step up to the MBLC variant on the current line.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X400-CM 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 MBL25X400-CM 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 MAL25X400-CM Is Used
PCB Conveyor Routing
Pushes PCBs across a 400 mm transfer gap between inline SMT machines using 245 N of force at 0.5 MPa.
Textile Bobbin Ejector
Extends 400 mm to eject wound textile bobbins from a winding spindle, relying on the CM round-end to accommodate slight misalignment.
Laser Marker Loader
Feeds small aluminum parts into a laser engraving station over a 400 mm reach within a compact 25 mm bore footprint.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X400-CM with MBL25X400-CM
To replace the MAL25X400-CM, order the MBL25X400-CM. Confirm the 25 mm bore, 400 mm stroke, PT tapered thread, and CM round-end back cover are correct for your fixture. Since this unit has no -S magnet, it cannot support a sensor; if you need position detection, order an MBL25X400S-CM and note that the MBL uses the newer CMSG, DMSG, or EMSG switches instead of the older CS1-M / DS1-M family. A plain bumper does not hold the load when air is lost, so add an external rod lock for vertical safety.
For sizing, this 25 mm bore yields 245 N push and 206 N pull at 0.5 MPa. If you need less force, step down to the 20 mm bore (157 N push), or step up to the 32 mm bore (402 N push) for heavier loads. With a 400 mm stroke on a 10 mm rod, side-load tolerance is low; use an external guide rail or a pivot knuckle to prevent rod bending.
Upgrade checklist
- ✓ Order the MBL25X400-CM (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 MBL25X400-CM instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X400-CM FAQ
Yes, the MAL25X400-CM is discontinued. The exact drop-in replacement is the MBL25X400-CM, offering the same 25 mm bore, 400 mm stroke, G1/8 port, and CM round-end mounting. The MBL uses a riveted body instead of threaded covers, but the performance is identical.
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. This specific SKU has no -S magnet, so it cannot accept a position sensor.
