This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X115SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X115SU 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 MAL25X115SU
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X115SU is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 115mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X115SU, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X115SU
The AirTAC MAL25X115SU is a discontinued double-acting aluminum mini round cylinder with a 25mm bore and 115mm stroke. It delivers 245 N of push force and 206 N of pull force at 0.5 MPa. The exact drop-in replacement is the MBL25X115SU, which matches the original bore, stroke, output force, G1/8 port, and flat-end U back cover.
This legacy unit features a 10mm carbon-steel rod with 20 um hard chrome plating guided by a self-lubricating front-cover bearing. Its heterogeneous two-way seal retains grease for long service life. The original MAL body uses threaded front and back covers, whereas the current MBL replacement features a riveted rolling-packed body. Because this SKU includes the -S magnet, it supports position sensing via older CS1-M or DS1-M switches. If you switch to the MBL, you must update your sensors to the current CMSG, DMSG, or EMSG families.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X115SU 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 MBL25X115SU 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 MAL25X115SU Is Used
PCB Router Z-Axis
Drives a light-duty routing spindle up and down 115mm, utilizing the 245N push force at 0.5 MPa to cleanly break through copper traces.
IC Tray Ejector
Pushes populated integrated circuit trays out of a testing nest, relying on the self-lubricating bearing guide to prevent rod chatter over short cycles.
Carton Flap Folder
Folds small cardboard flaps on a packaging line, where the fixed rubber bumper effectively absorbs the 115mm stroke impact without requiring adjustment.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X115SU with MBL25X115SU
To replace the MAL25X115SU, order the MBL25X115SU. Confirm your 115mm stroke requirement, the default PT port thread, and the rigid U flat-end back cover. Because this SKU has the -S magnet, plan to swap your legacy CS1-M or DS1-M switches for CMSG, DMSG, or EMSG sensors to fit the MBL body. If you need adjustable air cushioning—which the MAL lacks due to its fixed rubber bumper—upgrade to the MBLC series instead.
For sizing flexibility, stepping down to the 20mm bore yields 157 N of push force at 0.5 MPa, while stepping up to the 32mm bore provides 402 N. At 115mm of stroke, the 10mm rod is susceptible to bending under offset loads; use an external guide rail or a pivot bracket to manage side loads. A plain MBL does not hold its position when air is lost, so add an external rod lock or pilot-operated check valve if you need fail-safe load holding.
Upgrade checklist
- ✓ Order the MBL25X115SU (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 MBL25X115SU instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X115SU FAQ
Yes, the MAL25X115SU is discontinued. The exact drop-in replacement is the MBL25X115SU, which matches the 25mm bore, 115mm stroke, 50 kgf max force, G1/8 port, and U flat-end back cover. You will only need to update your sensors from the older CS1-M or DS1-M to the current CMSG, DMSG, or EMSG switches.
At 0.5 MPa, the push force is 245 N and the pull force is 206 N. At 0.7 MPa, the push force is 343 N, with a maximum theoretical force of 50 kgf at 1.0 MPa. It uses a 10mm carbon-steel rod with an M10x1.25 rod-end thread and operates at speeds of 30-800 mm/s.
