This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X275SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X275SU 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 MAL25X275SU
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X275SU is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 275mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X275SU, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X275SU
The AirTAC MAL25X275SU is a discontinued double-acting aluminum mini round cylinder. It delivers 245 N push and 206 N pull at 0.5 MPa from a 25 mm bore. AirTAC replaced this legacy unit with the MBL25X275SU, a drop-in alternative retaining the exact 275 mm stroke, G1/8 port, and U flat-end rear cover.
This SKU includes a -S magnet for position sensing. On the MAL, this works with older CS1-M or DS1-M switches, but the MBL replacement shifts to the current CMSG, DMSG, or EMSG sensor family. The original MAL body uses threaded front and back covers, whereas the MBL upgrade uses a riveted rolling-packed body. Both designs rely on a fixed rubber bumper for end-of-stroke damping rather than an adjustable cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X275SU 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 MBL25X275SU 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 MAL25X275SU Is Used
PCB Router Z-Axis
Drives the vertical plunge of a small-format PCB depaneling router, using the 245 N push at 0.5 MPa to cut 1.6 mm FR4 substrates cleanly.
Carton Flap Folder
Actuates a mechanical arm to tuck minor flaps on small electronics cartons, relying on the 275 mm stroke to clear the packaging frame.
Pallet Stop Gate
Raises a physical stop pin on a compact conveyor track to halt small plastic pallets, using the U flat-end cover for rigid frame mounting.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X275SU with MBL25X275SU
To replace the MAL25X275SU, order the MBL25X275SU. Confirm the 10 mm rod with its M10x1.25 thread, the default PT port, and the U flat-end back cover. Because this SKU has the -S magnet, plan to update your sensing to CMSG, DMSG, or EMSG switches. The fixed rubber bumper softens the stroke end but does not lock the rod; if you need to hold a load vertically without air, add an external rod lock or pilot-operated check valve. For heavier damping, the current MBLC line offers an adjustable air cushion.
At 275 mm of stroke, the 10 mm rod is highly susceptible to bending under off-center loads. Use an external guide rail to prevent side-load damage. If you need less force, step down to the 20 mm bore (157 N push @0.5 MPa). If you need more force, step up to the 32 mm bore (402 N push @0.5 MPa).
Upgrade checklist
- ✓ Order the MBL25X275SU (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 MBL25X275SU instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X275SU FAQ
Yes, the MAL25X275SU is discontinued. The exact drop-in replacement is the MBL25X275SU, which matches the 25 mm bore, 275 mm stroke, G1/8 port, and U flat-end mounting. You must upgrade your sensors because the -S magnet on the MAL works with CS1-M or DS1-M switches, while the MBL uses CMSG, DMSG, or EMSG switches.
The 25 mm bore generates 245 N push and 206 N pull at 0.5 MPa, and 343 N push at 0.7 MPa. The maximum theoretical force is 50 kgf at 1.0 MPa.
