This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X55SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X55SU 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).

The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X55SU is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 55mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X55SU, which matches its bore, stroke, force and mounting.
The AirTAC MAL25X55SU is a discontinued double-acting aluminum mini round cylinder with a 25mm bore and 55mm stroke. It delivers 245N of push force and 206N of pull force at 0.5 MPa, utilizing a G1/8 port and an M10x1.25 rod-end thread. The exact drop-in replacement is the MBL25X55SU, which matches the original bore, stroke, output force, port size, and U flat-end back cover for a seamless transition.
This legacy SKU includes a built-in magnet (-S) for position sensing and a U flat-end rear cover for rigid mounting. The older MAL body used threaded front and back covers, whereas the current MBL replacement features a riveted rolling-packed body for enhanced structural integrity. Additionally, the MAL -S magnet is designed for legacy CS1-M or DS1-M switches, while the MBL upgrade requires the modern CMSG, DMSG, or EMSG sensor families. The internal piston relies on a heterogeneous two-way seal that retains grease, and the carbon-steel rod features 20μm hard chrome plating to resist wear.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X55SU carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |

| 0.7 MPa | 344 N | — |
| Max (@1.0 MPa) | 50 kgf | |
The MBL25X55SU 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.

Replacement mapping: MAL → MBL, MSAL → MSBL, MTAL → MTBL, MALD → MBLD, MALJ → MBLJ.
Provides 245N of push force at 0.5 MPa to separate populated circuit panels, fitting easily into tight electronics assembly cells.
Drives a 55mm stroke to seat pin headers into plastic housings, using the rigid U flat-end cover to maintain precise alignment.
Actuates folding mechanisms on small packaging lines, where the 206N pull force reliably retracts the mechanism between cycles.
To replace the MAL25X55SU, order the MBL25X55SU, ensuring you keep the U flat-end back cover and PT tapered port thread. Because this SKU includes the -S magnet, you must upgrade your sensors from the legacy CS1-M or DS1-M to the current CMSG, DMSG, or EMSG switches. The cylinder uses a fixed rubber bumper for end-of-stroke damping; if your application requires an adjustable air cushion, step up to the MBLC variant on the current line. A plain bumper does not hold the load if air pressure drops, so add an external rod lock for fail-safe positioning.
For sizing flexibility, stepping down to the 20mm bore yields 157N of push force at 0.5 MPa, while stepping up to the 32mm bore provides 402N. The 55mm stroke is below the 300mm threshold, so side-load bending stress on the 10mm rod is minimal, but always minimize lateral loads to preserve the self-lubricating front-cover bearing guide.
Upgrade checklist
Yes, the MAL25X55SU is discontinued. The exact drop-in replacement is the MBL25X55SU, which offers the same 25mm bore, 55mm stroke, 245N push force, G1/8 port, and U flat-end mounting. You will need to update your sensors from the legacy CS1-M or DS1-M to the modern CMSG, DMSG, or EMSG switches.
The 25mm bore cylinder uses a G1/8 port and an M10x1.25 rod-end thread. At 0.5 MPa it provides 245N of push force and 206N of pull force. At 0.7 MPa the push force is 343N, and the maximum theoretical force is 50 kgf at 1.0 MPa.
