This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X280SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X280SU 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 MAL25X280SU
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X280SU is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 280mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X280SU, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X280SU
The AirTAC MAL25X280SU 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 features a 25 mm bore, a 280 mm stroke, and a G1/8 port. The exact drop-in replacement is the MBL25X280SU, which matches the bore, stroke, output force, port size, and mounting hardware.
This SKU includes a built-in magnet (-S) for position sensing and a U flat-end back cover for rigid rear mounting. The legacy MAL body uses threaded front and back covers, whereas the current MBL replacement features a riveted rolling-packed body. Additionally, the MAL -S magnet interfaces with older CS1-M / DS1-M switches, while the MBL replacement utilizes the modern CMSG / DMSG / EMSG sensor family. The piston relies on a heterogeneous two-way seal that retains grease, and the carbon-steel rod is protected by 20 um hard-chrome plating.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X280SU 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 MBL25X280SU 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 MAL25X280SU Is Used
PCB Shuttle Gate
Cycles a 280 mm travel gate to route bare printed circuit boards between SMT pick-and-place machines using 245 N push force at 0.5 MPa.
Pouch Reject Arm
Extends a paddle at 30-800 mm/s to push misaligned packaging pouches off a narrow conveyor belt into a reject chute.
Tester Socket Tray
Feeds empty IC test trays into automated handling equipment, depending on the U flat-end cover for a flush rigid frame mount.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X280SU with MBL25X280SU
To replace the MAL25X280SU, order the MBL25X280SU. Verify your 25 mm bore, 280 mm stroke, G1/8 port, and PT thread form. Because this unit has the -S magnet and a U flat-end back cover, expect a rigid rear mount; the MBL keeps these exact specifications but changes the sensor family from CS1-M / DS1-M to CMSG / DMSG / EMSG. If your application requires an adjustable air cushion rather than the standard fixed rubber bumper, step up to the MBLC variant on the current line.
For sizing flexibility, stepping down to the 20 mm bore yields 157 N of push force at 0.5 MPa, while stepping up to the 32 mm bore provides 402 N. Because the stroke is 280 mm, the 10 mm rod has low side-load tolerance; use an external guide rail or pivot bracket to prevent rod bending over this travel distance. Note that a plain MAL or MBL does not hold its load when air is lost—the rod drifts—so employ an external rod lock or pilot-operated check valve for position holding.
Upgrade checklist
- ✓ Order the MBL25X280SU (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 MBL25X280SU instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X280SU FAQ
Yes, the MAL25X280SU is discontinued. The exact drop-in replacement is the MBL25X280SU, offering the same 25 mm bore, 280 mm stroke, 50 kgf maximum force, G1/8 port, and U flat-end back cover. You will only need to update your position sensors, as the MBL uses CMSG / DMSG / EMSG switches instead of the older CS1-M / DS1-M type.
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 theoretical maximum force is 50 kgf at 1.0 MPa. It operates on filtered air at 0.1-1.0 MPa with a speed range of 30-800 mm/s.
