This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X175-S-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X175-S-U 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 MAL25X175-S-U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X175-S-U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 175mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X175-S-U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X175-S-U
The AirTAC MAL25X175-S-U is a discontinued double-acting aluminum mini round cylinder with a 25 mm bore and 175 mm stroke. It delivers 245 N push and 206 N pull at 0.5 MPa. AirTAC replaced this legacy unit with the MBL25X175-S-U, a drop-in alternative retaining the exact same force, G1/8 port, and U flat-end rear cover. The 175 mm travel makes it suitable for moderate reach tasks in compact assemblies.
This SKU includes a built-in magnet (-S) for position detection. On the original MAL body, this magnet pairs with the older CS1-M and DS1-M reed switches. The MBL replacement shifts to the current CMSG, DMSG, or EMSG sensor families. Mechanically, the old MAL relied on threaded front and back covers, whereas the modern MBL features a riveted rolling-packed barrel for faster assembly. Both designs use a carbon-steel rod with 20 um hard-chrome plating and a heterogeneous two-way seal that retains grease internally.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X175-S-U 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 MBL25X175-S-U 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 MAL25X175-S-U Is Used
PCB Depaneling Router
Deploys the 245 N push force at 0.5 MPa to separate routed circuit panels along a 175 mm travel path without stressing adjacent micro-components.
Connector Insertion Press
Drives a 10 mm rod over 175 mm to seat ribbon cable headers into housing slots, relying on the rigid U flat-end cover to maintain strict axial alignment.
Carton Flap Folder
Actuates a folding arm for small packaging boxes, utilizing the compact 25 mm bore to fit within tight conveyor side-frame clearances.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X175-S-U with MBL25X175-S-U
To replace this MAL, order the MBL25X175-S-U. Confirm the 25 mm bore, 175 mm stroke, G1/8 port, PT thread, and the U flat-end back cover. Because this SKU has the -S magnet, you must also upgrade your sensors: the legacy CS1-M and DS1-M switches will not fit the new body, so select CMSG, DMSG, or EMSG equivalents. The MAL uses a fixed rubber bumper, so if your application now requires adjustable end-of-stroke damping, step up to the MBLC variant on the current line.
For sizing flexibility, stepping down to the 20 mm bore drops the push force to 157 N at 0.5 MPa, while stepping up to the 32 mm bore increases it to 402 N. A plain bumper does not hold position if air pressure drops; add an external rod lock or pilot-operated check valve if drifting is unsafe. Because the 175 mm stroke combined with the 10 mm rod presents a bending risk under lateral stress, use an external guide rail or a pivot mount to absorb any side-load.
Upgrade checklist
- ✓ Order the MBL25X175-S-U (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 MBL25X175-S-U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X175-S-U FAQ
Yes, the MAL25X175-S-U is discontinued. The exact drop-in replacement is the MBL25X175-S-U. It matches the 25 mm bore, 175 mm stroke, 245 N push force, G1/8 port, and U flat-end cover. You must swap your CS1-M or DS1-M sensors for the newer CMSG, DMSG, or EMSG switches.
At 0.5 MPa it provides 245 N push and 206 N pull. At 0.7 MPa the push force is 343 N, with a theoretical maximum of 50 kgf at 1.0 MPa. It operates on filtered air between 0.1-1.0 MPa, runs at 30-800 mm/s, and uses a fixed rubber bumper rather than an adjustable cushion.
