This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X450-S-CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X450-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 MAL25X450-S-CM
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X450-S-CM is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 450mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X450-S-CM, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X450-S-CM
The AirTAC MAL25X450-S-CM is a discontinued double-acting aluminum mini round cylinder. Delivering 245 N of push force at 0.5 MPa, this 25 mm bore unit features a 450 mm stroke and a G1/8 port. The exact drop-in replacement is the MBL25X450-S-CM, matching the original bore, stroke, output force, port size, and CM round-end mounting. You can order the MBL as a direct upgrade.
This legacy SKU includes a built-in magnet (-S) for position detection. The older MAL cylinder used a threaded front and back cover assembly, whereas the current MBL replacement features a riveted rolling-packed body for structural rigidity. Because this is a -S model, note that the original CS1-M or DS1-M switches are retired; the MBL replacement requires the modern CMSG, DMSG, or EMSG sensor family. The piston relies on a heterogeneous two-way seal that retains grease, operating alongside a self-lubricating front-cover bearing guide.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X450-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 | — |

Where the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X450-S-CM Is Used
PCB Router Ejection
Pushes a routed printed circuit board panel out of a routing machine fixture using 245 N of thrust, relying on the 450 mm stroke to clear the work envelope entirely.
Carton Flap Folder
Extends 450 mm to fold the secondary flap of a small packaging carton as it travels down a conveyor, using the CM round-end cover to accommodate the arc of the linkage.
Drawer Push-Out
Extracts a shallow component drawer from a dense testing station, requiring the full 450 mm travel to present the electronics tray to the operator.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X450-S-CM with MBL25X450-S-CM
To replace the MAL25X450-S-CM, order the MBL25X450-S-CM. Verify that your pneumatic plumbing matches the G1/8 port and your rod end mating hardware fits the M10x1.25 thread. Retain the CM round-end back cover to preserve your existing pivot mounting geometry. Because this configuration includes the -S magnet, you must upgrade your position sensing to the MBL-compatible CMSG, DMSG, or EMSG switches, as the older CS1-M and DS1-M units will not fit the new body. The standard MAL uses a fixed rubber bumper for end-of-stroke impact absorption; if your application requires an adjustable air cushion, step up to the MBLC variant on the current line.
When sizing, evaluate stepping down to a 20 mm bore (157 N push at 0.5 MPa) if your load is light, or up to a 32 mm bore (402 N push at 0.5 MPa) for higher mass. At 450 mm of stroke, the 10 mm rod is highly susceptible to bending under lateral stress; you must use an external guide rail to prevent premature seal failure. Furthermore, a plain MAL or MBL cylinder does not hold its position when air pressure is lost—the rod will drift. To lock a suspended load, install an external rod lock or a pilot-operated check valve.
Upgrade checklist
- ✓ Order the MBL25X450-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 MBL25X450-S-CM instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X450-S-CM FAQ
Yes, the MAL25X450-S-CM is discontinued. The exact drop-in replacement is the MBL25X450-S-CM, which matches the 25 mm bore, 450 mm stroke, 245 N push force, G1/8 port, and CM round-end mounting. The MBL uses a riveted body instead of threaded covers, and your CS1-M/DS1-M sensors must be upgraded to CMSG/DMSG/EMSG switches.
The 25 mm bore provides 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. The port size is G1/8, the rod is 10 mm, and the rod-end thread is M10x1.25.
