This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X120U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X120U 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 MAL25X120U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X120U 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 MBL25X120U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X120U
The AirTAC MAL25X120U is a discontinued compact double-acting aluminum mini round cylinder with a 25mm bore and 120mm stroke. It delivers 245N push and 206N pull at 0.5MPa, making it suited for mid-range small-part handling. The exact drop-in replacement is the MBL25X120U, offering identical bore, stroke, force, G1/8 port, and flat-end U back cover compatibility.
This legacy unit features a fixed rubber bumper and threaded front/back covers, whereas the current MBL uses a riveted rolling-packed body. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor. The piston relies on a heterogeneous two-way grease-retaining seal, and the carbon-steel rod has 20um hard chrome plating for wear resistance.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X120U 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 MBL25X120U 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 MAL25X120U Is Used
PCB Conveyor Gating
Provides 245N push at 0.5MPa to actuate a pneumatic diverter gate on a PCB conveyor, moving panels into an inspection lane within a tight 120mm stroke envelope.
Socket Test Press
Drives an IC socket test head with 206N pull force, utilizing the rigid U flat-end back cover to maintain precise perpendicular alignment during automated contact testing.
Carton Flap Folder
Folds small corrugated carton flaps at 30-800mm/s, where the fixed rubber bumper absorbs the repetitive end-of-stroke impact without requiring complex adjustable cushioning.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X120U with MBL25X120U
To replace the MAL25X120U, order the MBL25X120U. Confirm the 25mm bore, 120mm stroke, G1/8 port, and default PT tapered threads. The U flat-end back cover provides rigid rear mounting; if your machine needs arcing movement, step up to the CA pivot cover. If you need position sensing, you must select an MBL with the -S option, which uses the newer CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M.
For sizing flexibility, the next size down is the 20mm bore (157N push @0.5MPa) for lighter loads, and the next size up is the 32mm bore (402N push @0.5MPa) for higher force. At 120mm stroke, side-load stress is moderate, but the 10mm rod has low side-load tolerance; use an external guide rail for heavy offset loads. The fixed rubber bumper softens end-of-stroke impact but does not lock the rod if air pressure drops—add a pilot-operated check valve for position holding. If you need adjustable cushioning, step up to the MBLC variant on the current line.
Upgrade checklist
- ✓ Order the MBL25X120U (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 MBL25X120U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X120U FAQ
Yes, the MAL series is end-of-life. The exact drop-in replacement is the MBL25X120U. It matches the 25mm bore, 120mm stroke, 245N push force, G1/8 port, and U flat-end mounting. The MBL upgrades the body to a riveted rolling-packed design while keeping the same dimensions.
At 0.5MPa it delivers 245N push and 206N pull; at 0.7MPa it pushes 343N, with a maximum theoretical force of 50kgf at 1.0MPa. Because this specific MAL25X120U SKU lacks the -S magnet, it cannot accept a position sensor. To add sensing on the replacement, order an MBL25X120S, which uses CMSG/DMSG/EMSG switches.
