This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X170U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X170U 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 MAL25X170U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X170U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 170mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X170U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X170U
The AirTAC MAL25X170U is a discontinued compact double-acting aluminum mini round cylinder. Delivering 245 N of push force and 206 N of pull force at 0.5 MPa, it is engineered for small-part actuation in tight spaces. The exact drop-in replacement is the MBL25X170U, which matches the 25 mm bore, 170 mm stroke, G1/8 port, and U flat-end back cover exactly.
This legacy SKU lacks a built-in magnet (-S), so it cannot accept a position sensor. The original MAL body uses threaded front and back covers, whereas the current MBL replacement features a riveted rolling-packed body. Internally, a heterogeneous two-way seal retains grease, and the 10 mm carbon-steel rod is protected by 20 um hard chrome plating for wear resistance.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X170U 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 MBL25X170U 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 MAL25X170U Is Used
PCB Depaneling Router
Provides 245 N of push force at 0.5 MPa to actuate the clamping gate on a compact PCB depaneling router, ensuring panels stay fixed during routing.
IC Test Handler Ejection
Drives the ejection pins inside an IC test handler, using its 170 mm stroke to push tested components out of the test socket into the sorting bin.
Pouch Sealing Jaw
Powers the sealing jaw assembly on a vertical pouch filling machine, moving 170 mm to close the seal bars around flexible packaging film.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X170U with MBL25X170U
To replace the MAL25X170U, order the MBL25X170U. Verify your 170 mm stroke, G1/8 port, and the rigid U flat-end back cover. Because this SKU has no -S magnet, you cannot mount a position sensor; if you need end-of-stroke detection, order the MBL25X170US and prepare to switch from the old CS1-M / DS1-M switches to the current CMSG / DMSG / EMSG family. If your load drifts when air is removed, know that the fixed rubber bumper is not a lock—you must add an external rod lock or pilot-operated check valve. If a cushion is required, step up to the MBLC line.
For sizing flexibility, stepping down to the 20 mm bore drops thrust to 157 N push at 0.5 MPa, while stepping up to the 32 mm bore increases thrust to 402 N push at 0.5 MPa. At 170 mm stroke, side-load stress on the 10 mm rod is moderate; ensure rigid U-back mounting to prevent rod bending.
Upgrade checklist
- ✓ Order the MBL25X170U (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 MBL25X170U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X170U FAQ
Yes, the MAL25X170U is discontinued. The exact drop-in replacement is the AirTAC MBL25X170U. It provides the same 25 mm bore, 170 mm stroke, G1/8 port, and U flat-end back cover. The main upgrade is that the MBL uses a riveted rolling-packed body instead of the MAL's threaded covers.
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. The maximum theoretical force is 50 kgf at 1.0 MPa. This unit has a fixed rubber bumper, not an adjustable cushion.
