This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X400-S-CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X400-S-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-S-CM
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X400-S-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-S-CM, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X400-S-CM
The AirTAC MAL25X400-S-CM is a discontinued double-acting aluminum mini round cylinder. It delivers 245 N of push force and 206 N of pull force at 0.5 MPa, utilizing a 10 mm carbon-steel rod with 20 um hard chrome plating. The direct drop-in replacement is the MBL25X400-S-CM, which matches the 25 mm bore, 400 mm stroke, G1/8 port, and 50 kgf maximum force exactly.
This legacy unit features a built-in magnet (-S) for position sensing and a CM round-end back cover. On the MAL, the magnet interfaces with older CS1-M / DS1-M reed switches, whereas the MBL replacement requires current CMSG / DMSG / EMSG sensors. The original MAL body uses threaded front and back covers, while the upgraded MBL uses a riveted rolling-packed body. Both designs rely on a fixed rubber bumper for end-of-stroke deceleration rather than an adjustable air cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X400-S-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-S-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-S-CM Is Used
PCB Edge-Gate Diverter
Extends a 400 mm arm to gate thin printed circuit boards on a high-speed SMT conveyor, using the 245 N push force to overcome guide friction without crushing the panel edges.
Textile Yarn Guide
Traverses a yarn thread guide across a winding spool at 30-800 mm/s, relying on the CM round-end cover to self-align under the slight arcing motion of the long stroke.
Carton Push-Off Arm
Pushes lightweight folded cartons from a staging table to a packing chute, where the self-lubricating front-cover bearing prevents stickiness during continuous 400 mm retraction cycles.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X400-S-CM with MBL25X400-S-CM
To replace the MAL25X400-S-CM, order the MBL25X400-S-CM. Verify your port plumbing matches the G1/8 thread and that your rod-end thread is M10x1.25. Because this SKU includes a magnet (-S), you must upgrade your position sensing from the legacy CS1-M / DS1-M switches to the modern CMSG / DMSG / EMSG family. The CM round-end back cover accommodates arcing or pivoting rod loads, which is highly recommended for a 400 mm stroke to prevent rod bending.
For sizing context, stepping down to the 20 mm bore drops the 0.5 MPa push force to 157 N, while stepping up to the 32 mm bore increases it to 402 N. A plain MAL or MBL cylinder cannot hold a load when air pressure is lost; the rod will drift. If you need fail-safe holding, install an external rod lock or a pilot-operated check valve. If end-of-stroke impact is too harsh, note that the MAL only has a fixed rubber bumper, so you should look at the MBLC variant on the current line for an adjustable air cushion.
Upgrade checklist
- ✓ Order the MBL25X400-S-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-S-CM instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X400-S-CM FAQ
Yes, the MAL series is end-of-life. The exact drop-in replacement is the MBL25X400-S-CM. It matches the 25 mm bore, 400 mm stroke, G1/8 port, 10 mm rod, and CM round-end mounting. You must only change your position sensors from the old CS1-M / DS1-M switches to the new CMSG / DMSG / EMSG family.
The 25 mm bore operates at 0.1-1.0 MPa with a proof pressure of 1.5 MPa. The thrust is 245 N push and 206 N pull at 0.5 MPa, 343 N push at 0.7 MPa, and a maximum theoretical force of 50 kgf at 1.0 MPa. It uses a fixed rubber bumper, not an adjustable cushion.
