This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X25-S-U-H — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X25-S-U-H 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 MAL25X25-S-U-H
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X25-S-U-H is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 25mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X25-S-U-H, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X25-S-U-H
The AirTAC MAL25X25-S-U-H is a discontinued compact double-acting aluminum mini round cylinder. Delivering 245 N of push force at 0.5 MPa, it features a 25 mm bore, a 10 mm carbon-steel rod with 20 µm hard chrome plating, and a U flat-end back cover. The exact drop-in replacement is the MBL25X25-S-U-H, matching the stroke, force, G1/8 port, and mounting footprint.
This legacy unit uses a heterogeneous two-way grease-retaining seal and a self-lubricating front-cover bearing guide. Because this SKU includes the -S magnet, it supports position sensing via the older CS1-M or DS1-M switches. When upgrading to the riveted rolling-packed body of the MBL, you must migrate to the current CMSG, DMSG, or EMSG sensor family. The original MAL relies on a fixed rubber bumper for end-of-stroke absorption, whereas the modern MBLC variant offers an adjustable air cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X25-S-U-H 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 | — |

Where the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X25-S-U-H Is Used
PCB Router Clamping
Secures small printed circuit boards inside a desktop routing machine, utilizing the 245 N push force and 25 mm stroke to lock panels during high-speed spindle milling.
Chip Test Handler Gate
Actuates a micro-gate in semiconductor test handlers, using the -S magnet and CS1-M sensor to verify arm position before dispensing integrated circuits.
Carton Flap Folder
Folds small corrugated flaps on a compact packaging conveyor, where the U flat-end cover mounts rigidly to the machine frame without inducing pivot arc stress.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X25-S-U-H with MBL25X25-S-U-H
To replace this MAL25X25-S-U-H, order the MBL25X25-S-U-H. Verify your 10 mm rod-end thread (M10x1.25) and the default PT tapered port thread. If your application requires less force, step down to the 20 mm bore offering 157 N push at 0.5 MPa. If you need more power, step up to the 32 mm bore providing 402 N push at 0.5 MPa. Remember that a plain cylinder does not hold a load when air pressure drops; the rod drifts, so employ an external rod lock or pilot-operated check valve for fail-safe holding. If your machine requires end-of-stroke deceleration beyond the fixed rubber bumper, select the MBLC series for its adjustable air cushion.
Upgrade checklist
- ✓ Order the MBL25X25-S-U-H (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 MBL25X25-S-U-H instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X25-S-U-H FAQ
Yes, the MAL25X25-S-U-H is discontinued. The exact drop-in replacement is the MBL25X25-S-U-H, which matches the 25 mm bore, 25 mm stroke, 245 N force, G1/8 port, and U flat-end mounting. Note that the MBL uses a riveted body instead of threaded covers, and you must upgrade from the older CS1-M/DS1-M sensors to the CMSG/DMSG/EMSG family.
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.
