This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X500-S-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X500-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 MAL25X500-S-U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X500-S-U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 500mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X500-S-U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X500-S-U
The AirTAC MAL25X500-S-U is a discontinued double-acting aluminum mini round cylinder with a 25mm bore and 500mm stroke. It delivers 245N push and 206N pull at 0.5 MPa. The direct drop-in replacement is the MBL25X500-S-U, which matches the bore, stroke, force, G1/8 port, and U flat-end mounting exactly.
This legacy unit features a built-in magnet (-S) for position sensing and a fixed rubber bumper. An important upgrade detail is that the MAL uses threaded front and back covers, whereas the modern MBL utilizes a riveted rolling-packed body. Additionally, the MAL magnet pairs with older CS1-M or DS1-M reed switches, while the MBL replacement requires current CMSG, DMSG, or EMSG solid-state sensors. The 10mm carbon-steel rod has a 20um hard-chrome plating, and the piston relies on a heterogeneous two-way seal that retains grease for long service life.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X500-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 MBL25X500-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 MAL25X500-S-U Is Used
PCB Edge Conveyor Transfer
Pushes populated circuit boards across a 500mm gap between edge-belt conveyors, using the 245N force to bridge the transfer without damaging fragile components.
Carton Flap Folder
Folds secondary cardboard flaps on a packaging line, where the 206N pull retracts the arm in tight spaces and the U flat-end rear handles rigid mounting.
Lathe Tailstock Ejector
Ejects small metal machined bushings from a lathe tailstock over a 500mm reach, relying on the 20um hard-chrome plating to resist wear during repeated strokes.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X500-S-U with MBL25X500-S-U
To replace this MAL25X500-S-U, order the MBL25X500-S-U. Verify your porting (PT standard G1/8), the U flat-end rigid back cover, and the -S magnet. Because the sensor family changes, you must upgrade from the old CS1-M/DS1-M switches to the CMSG/DMSG/EMSG series. If your application needs adjustable end-cushioning to absorb kinetic energy, step up to the MBLC variant, as the MAL only has a fixed rubber bumper.
For sizing flexibility, stepping down to the 20mm bore yields 157N push at 0.5 MPa, while stepping up to the 32mm bore provides 402N push. Because this is a 500mm stroke on a 10mm rod, side-load tolerance is very low; you must use an external guide rail or a pivot mounting to prevent rod bending. A plain MAL/MBL does not hold its load when air is lost, so add an external rod lock or pilot-operated check valve for fail-safe holding.
Upgrade checklist
- ✓ Order the MBL25X500-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 MBL25X500-S-U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X500-S-U FAQ
Yes, the MAL25X500-S-U is discontinued. The exact drop-in replacement is the MBL25X500-S-U, offering the same 25mm bore, 500mm stroke, G1/8 port, U flat-end back cover, and -S magnet. You will need to update your sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG.
The 25mm bore provides 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 0.1-1.0 MPa with a speed range of 30-800 mm/s.
