This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X650-S-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X650-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 MAL25X650-S-U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X650-S-U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 650mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X650-S-U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X650-S-U
The AirTAC MAL25X650-S-U is a discontinued double-acting aluminum mini round cylinder with a 25mm bore and a 650mm stroke. Because 650mm exceeds the 500mm standard limit, this is a non-standard, made-to-order configuration. It delivers 245N of push force and 206N of pull force at 0.5 MPa. AirTAC replaced the entire MAL series with the MBL line, making the MBL25X650-S-U the exact drop-in replacement. It matches the bore, stroke, output force, G1/8 port, and U flat-end back cover perfectly.
Two critical engineering details define this SKU. First, the original MAL uses threaded front and back covers on the barrel, whereas the modern MBL replacement uses a riveted rolling-packed body. Second, the -S magnet on this MAL works with the older CS1-M and DS1-M switches; if you upgrade to the MBL25X650-S-U, you must switch to the current CMSG, DMSG, or EMSG sensor family. The cylinder relies on a fixed rubber bumper for end-of-stroke damping and uses a heterogeneous two-way seal that retains grease on the carbon-steel rod, which features 20um hard-chrome plating.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X650-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 MBL25X650-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 MAL25X650-S-U Is Used
PCB Conveyor Diverter
Pushes lightweight routing gates along a 650mm travel path in electronics assembly lines, matching the 245N push force to overcome guide friction without damaging panels.
Test Handler Tray Shuttle
Moves empty IC test trays between loading stations over a long 650mm stroke, relying on the self-lubricating front-cover bearing guide to prevent stick-slip during rapid 30-800 mm/s cycles.
Small Parts Ejector Chute
Actuates a diverter arm over a parts bin, using the U flat-end cover for rigid fixed mounting while the heterogeneous two-way seal maintains consistent 206N pull force during retraction.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X650-S-U with MBL25X650-S-U
To replace this MAL with the MBL25X650-S-U, confirm the 25mm bore, 650mm non-standard stroke, PT thread, and U flat-end back cover. The U cover provides rigid, non-pivoting mounting. Because this is a -S model, note that the MBL replacement requires CMSG, DMSG, or EMSG sensors instead of the legacy CS1-M or DS1-M switches. If you need an adjustable air cushion instead of the fixed rubber bumper, look at the MBLC variant on the current line.
For sizing flexibility, the next size down is the 20mm bore, which yields 157N push at 0.5 MPa, and the next size up is the 32mm bore, which yields 402N push at 0.5 MPa. At 650mm, the 10mm rod has low side-load tolerance; you must use an external guide or a pivot bracket to prevent rod bending. Also, a plain MAL or MBL does not hold its load when air is lost—the rod drifts—so add an external rod lock or pilot-operated check valve for fail-safe holding.
Upgrade checklist
- ✓ Order the MBL25X650-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 MBL25X650-S-U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X650-S-U FAQ
Yes, the MAL25X650-S-U is discontinued. The exact drop-in replacement is the MBL25X650-S-U, which matches the 25mm bore, 650mm stroke, G1/8 port, U flat-end cover, and output force. You only need to update your sensor choice, as the MBL uses CMSG, DMSG, or EMSG switches instead of the older CS1-M or DS1-M.
The 25mm bore double-acting cylinder 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 uses a G1/8 port, a 10mm rod with an M10x1.25 thread, operates at 0.1-1.0 MPa, and has a speed range of 30-800 mm/s.
