This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X55U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X55U 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 MAL25X55U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X55U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 55mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X55U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X55U
The AirTAC MAL25X55U 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 utilizes a 10 mm carbon-steel rod with a 20 um hard chrome plating to resist wear. The exact drop-in replacement is the MBL25X55U, which matches the 25 mm bore, 55 mm stroke, G1/8 port, and U flat-end back cover perfectly.
This legacy unit features a fixed rubber bumper for end-of-stroke damping rather than an adjustable air cushion. The original MAL body uses threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed body for improved structural integrity. Because this specific SKU lacks the -S magnet suffix, it cannot accommodate a position sensor and should not be used if electronic rod detection is required.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X55U 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 MBL25X55U 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 MAL25X55U Is Used
PCB Depaneling Router
Actuates a cutting blade to singulate printed circuit boards, utilizing the 245 N push force at 0.5 MPa to cleanly sever the substrate without stressing adjacent components.
Carton Flap Folder
Folds minor flaps on small packaging boxes in a tight conveyor space, relying on the 55 mm stroke and U flat-end rigid mounting to maintain alignment.
Connector Insertion Press
Pushes ribbon cable connectors into PCB headers, using the fixed rubber bumper to soften the end of stroke and prevent damage to delicate electronic pins.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X55U with MBL25X55U
To replace the MAL25X55U, order the MBL25X55U and confirm the 55 mm stroke, G1/8 port, and U flat-end back cover. The default PT tapered thread form must be verified against your existing fittings. If your application requires an adjustable air cushion rather than a fixed rubber bumper, step up to the MBLC equivalent on the current line. Note that a plain MBL cylinder does not hold its position when air is lost; the rod will drift, so an external rod lock or pilot-operated check valve is required for fail-safe load holding.
When sizing, you can step down to the 20 mm bore (157 N push at 0.5 MPa) for lighter loads, or up to the 32 mm bore (402 N push at 0.5 MPa) for higher force. The 55 mm stroke is short enough to avoid rod bending, but the 10 mm rod has low side-load tolerance, so rigid mounting is essential.
Upgrade checklist
- ✓ Order the MBL25X55U (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 MBL25X55U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X55U FAQ
Yes, the MAL25X55U is discontinued. The exact drop-in replacement is the MBL25X55U, which shares the same 25 mm bore, 55 mm stroke, G1/8 port, and U flat-end mounting. The MBL uses a riveted rolling-packed body instead of the threaded covers found on the MAL.
At 0.5 MPa it provides 245 N push and 206 N pull force, 343 N push at 0.7 MPa, and a maximum theoretical force of 50 kgf at 1.0 MPa. Because this SKU lacks the -S magnet suffix, it cannot accept a position sensor like the older CS1-M or DS1-M switches.
