This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X120SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X120SU 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 MAL25X120SU
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X120SU is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 120mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X120SU, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X120SU
The AirTAC MAL25X120SU is a discontinued compact double-acting aluminum mini round cylinder with a 25mm bore and 120mm stroke. It delivers 245N push and 206N pull force at 0.5MPa, making it a mid-range actuator for small parts. AirTAC replaced this legacy unit with the MBL25X120SU, a drop-in replacement sharing the exact bore, stroke, output force, G1/8 port, and flat-end U back cover.
This SKU includes a -S magnet for position sensing. The original MAL works with older CS1-M and DS1-M reed switches, while the MBL replacement uses current CMSG, DMSG, or EMSG sensors. The legacy MAL features threaded front and back covers, whereas the MBL uses a riveted rolling-packed body. Both rely on a fixed rubber bumper for end-of-stroke damping, not an adjustable cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X120SU 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 MBL25X120SU 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 MAL25X120SU Is Used
PCB Router Z-Axis
Drives the vertical plunge of a PCB depaneling router, using the 245N push force to maintain steady cutting depth on 1.6mm boards.
IC Test Socket Clamp
Holds a test socket rigidly against a semiconductor package, leveraging the 206N pull force and flat-end U cover for a flush machine mount.
Pouch Sealing Jaw
Actuates a heated sealing jaw on a vertical form-fill-seal machine, where the 120mm stroke accommodates varying pouch widths.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X120SU with MBL25X120SU
To replace the MAL25X120SU, order the MBL25X120SU. Confirm your 25mm bore, 120mm stroke, G1/8 PT port, and flat-end U back cover. Because this SKU has a -S magnet, you must upgrade your sensors from the old CS1-M or DS1-M switches to the CMSG, DMSG, or EMSG family used on the MBL. The MAL uses a fixed rubber bumper; if your application needs adjustable end-cushioning, step up to the MBLC series instead.
If you need less force, the 20mm bore neighbor provides 157N push at 0.5MPa. If you need more power, the 32mm bore gives 402N push at 0.5MPa. Since this is a 120mm stroke, the 10mm carbon-steel rod with 20um hard chrome plating has limited side-load tolerance; use an external guide rail or a pivot bracket to prevent rod bending. A plain cylinder does not hold a load when air is lost, so add an external rod lock or pilot-operated check valve for fail-safe positioning.
Upgrade checklist
- ✓ Order the MBL25X120SU (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 MBL25X120SU instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X120SU FAQ
Yes, the MAL series is end-of-life. The exact drop-in replacement is the MBL25X120SU. It matches the 25mm bore, 120mm stroke, G1/8 port, flat-end U cover, and output force. The body changes from threaded covers to a riveted rolling-packed design, and the -S magnet now requires CMSG, DMSG, or EMSG sensors instead of the older CS1-M or DS1-M switches.
At 0.5MPa, the 25mm bore provides 245N push and 206N pull force. At 0.7MPa, push force is 343N. The maximum theoretical force is 50kgf at 1.0MPa. It uses a G1/8 port, a 10mm carbon-steel rod with M10x1.25 thread, and operates at 0.1-1.0MPa with a speed range of 30-800mm/s.
