This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X70SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X70SU 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 MAL25X70SU
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X70SU is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 70mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X70SU, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X70SU
The AirTAC MAL25X70SU is a discontinued double-acting aluminum mini round cylinder with a 25mm bore and 70mm stroke. It delivers 245N push and 206N pull at 0.5 MPa. The exact drop-in replacement is the MBL25X70SU, which matches the bore, stroke, output force, G1/8 port, and U flat-end mounting. This cylinder features a Ø10mm carbon-steel rod with 20um hard-chrome plating and a heterogeneous two-way seal that retains grease for long service life.
This legacy SKU includes a built-in magnet (-S) for position detection. On the MAL, this magnet pairs with the older CS1-M / DS1-M switches, while the MBL replacement transitions to the current CMSG / DMSG / EMSG sensor family. The original MAL body uses threaded front and back covers, whereas the upgraded MBL utilizes a riveted rolling-packed body. Both designs rely on a fixed rubber bumper rather than an adjustable cushion.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X70SU Technical Specifications

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X70SU 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 MBL25X70SU 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 MAL25X70SU Is Used
PCB Depaneling Router
Provides 245N of push force to plunge and guide a router bit on an electronics assembly line, with the 70mm stroke accommodating varying board thicknesses.
Carton Flap Folding
Uses its 206N pull force to actuate a mechanical arm that tucks minor flaps on packaging lines, fitting easily into compact machine frames.
Small Parts Ejection
Pushes lightweight molded plastic parts out of a die with a 70mm extension, relying on the self-lubricating bearing guide to maintain alignment.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X70SU with MBL25X70SU
To replace the MAL25X70SU, order the MBL25X70SU. Confirm the 70mm stroke, G1/8 port, PT thread, and the U flat-end back cover. Because this SKU includes the -S magnet, note that your existing CS1-M or DS1-M sensors will need to be upgraded to CMSG, DMSG, or EMSG switches to function with the new MBL body. If your application requires adjustable end-of-stroke cushioning, step up to the MBLC variant on the current line, as the MAL only offers a fixed rubber bumper.
For sizing flexibility, the neighboring 20mm bore provides 157N of push force at 0.5 MPa, while stepping up to the 32mm bore yields 402N. Keep in mind that a plain cylinder does not hold its position if air pressure drops; the rod will drift. Use an external rod lock or pilot-operated check valve if the load must be safely held.
Upgrade checklist
- ✓ Order the MBL25X70SU (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 MBL25X70SU instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X70SU FAQ
Yes, the AirTAC MAL25X70SU is discontinued. The exact drop-in replacement is the MBL25X70SU. It offers the same 25mm bore, 70mm stroke, 50 kgf maximum force, G1/8 port, and U flat-end mounting. You will need to update your sensors, as the MBL uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M type.
The 25mm bore provides a push force of 245N and a pull force of 206N at 0.5 MPa. At 0.7 MPa, the push force increases to 343N. The theoretical maximum force is 50 kgf at 1.0 MPa.
