This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X75-S-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X75-S-U 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 MAL25X75-S-U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X75-S-U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 75mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X75-S-U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X75-S-U
The AirTAC MAL25X75-S-U is a discontinued double-acting aluminum mini round cylinder with a 25mm bore and 75mm stroke. It delivers 245N of push force and 206N of pull force at 0.5 MPa, utilizing a G1/8 port and an M10x1.25 rod-end thread. The exact drop-in replacement is the MBL25X75-S-U, which matches the original bore, stroke, output force, port size, and mounting accessories for a seamless upgrade.
This legacy unit features a U flat-end back cover for rigid rear mounting and includes a built-in magnet (-S) for position sensing. Two key structural differences exist in the upgrade path: the MAL uses threaded front and back covers on the barrel, whereas the MBL uses a riveted rolling-packed body. Furthermore, the MAL magnet interfaces with legacy CS1-M or DS1-M reed switches, while the MBL replacement requires the current CMSG, DMSG, or EMSG sensor family. The cylinder relies on a fixed rubber bumper for end-of-stroke deceleration and uses a heterogeneous two-way seal to retain grease, paired with a self-lubricating front-cover bearing guide.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X75-S-U 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 MBL25X75-S-U 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 MAL25X75-S-U Is Used
PCB Conveyor Routing
Ideal for routing populated PCBs on a 75mm stroke, using 245N of push force at 0.5 MPa to gently divert boards into testing lanes without damaging components.
Small-Part Ejection
Provides 206N of pull force to extract plastic injection-molded clips from a rigid U-mount rear fixture, operating at speeds between 30-800 mm/s.
Carton Flap Folding
Employs the -S magnet and legacy CS1-M switches to time the 75mm stroke perfectly for folding small packaging flaps in tight-tolerance cartoning machines.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X75-S-U with MBL25X75-S-U
To replace the MAL25X75-S-U, order the MBL25X75-S-U, ensuring you retain the 25mm bore, 75mm stroke, G1/8 PT thread, U flat-end back cover, and magnet. If your application requires less force, step down to the 20mm bore version, which provides 157N of push force at 0.5 MPa. If you need more power, step up to the 32mm bore, delivering 402N of push force at 0.5 MPa. Because the stroke is 75mm, side-load stress on the 10mm carbon-steel rod is moderate, but external guides are recommended if the load is not perfectly axial. Note that the fixed rubber bumper softens end-of-stroke impacts but does not lock the rod; if you need adjustable air cushioning, you must specify the MBLC variant on the current line. Additionally, a plain MBL does not hold position when air pressure is lost, so employ an external rod lock or pilot-operated check valve for fail-safe load holding.
Upgrade checklist
- ✓ Order the MBL25X75-S-U (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 MBL25X75-S-U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X75-S-U FAQ
Yes, the MAL25X75-S-U is discontinued. The exact drop-in replacement is the MBL25X75-S-U, which offers the same 25mm bore, 75mm stroke, G1/8 port, and U flat-end back cover. The MBL uses a riveted rolling-packed body instead of threaded covers, and you must upgrade your sensors from the older CS1-M or DS1-M to the CMSG, DMSG, or EMSG family.
The 25mm bore delivers 245N push and 206N pull at 0.5 MPa, 343N push at 0.7 MPa, and a maximum theoretical force of 50 kgf at 1.0 MPa. It operates at pressures from 0.1-1.0 MPa and uses a fixed rubber bumper, not an adjustable cushion.
