This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X550-CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X550-CM 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 MAL25X550-CM
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X550-CM is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 550mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X550-CM, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X550-CM
The AirTAC MAL25X550-CM is a discontinued double-acting aluminum mini round cylinder with a 25mm bore and a 550mm stroke. Because 550mm exceeds the 500mm standard limit, this is a non-standard, made-to-order length. It delivers 245N push and 206N pull force at 0.5MPa. The exact drop-in replacement is the MBL25X550-CM, which matches the bore, stroke, force, G1/8 port, and CM round-end back cover.
This legacy unit features a CM round-end back cover, which is distinct from the flat U or pivot CA styles, providing a specific rounded mounting interface for legacy fixtures. The original MAL body uses threaded front and back covers on the barrel, whereas the modern MBL replacement utilizes a riveted rolling-packed body for structural integrity. Additionally, because this specific SKU lacks an -S magnet, it cannot accept a position sensor and cannot be used for stroke-end detection without external hardware.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X550-CM 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 MBL25X550-CM 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 MAL25X550-CM Is Used
PCB Conveyor Diverter
Actuates a diverter gate on a printed circuit board conveyor, utilizing the 245N push force at 0.5MPa to redirect lightweight panels without damaging delicate traces.
Long-Reach Carton Pusher
Employs the 550mm stroke to push small packaging cartons from a secondary accumulation lane onto a main packaging line in tight spatial constraints.
Textile Yarn Guide
Traverses a yarn guide carriage across a narrow weaving loom, where the CM round-end back cover accommodates slight angular misalignment during the travel path.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X550-CM with MBL25X550-CM
To replace the MAL25X550-CM, order the MBL25X550-CM, ensuring you retain the exact 25mm bore, 550mm non-standard stroke, G1/8 port, and CM round-end cover. If your application requires a position sensor, you must upgrade to an MBL25X550S-CM, noting that the modern MBL uses CMSG, DMSG, or EMSG switches rather than the older CS1-M or DS1-M sensors. If you need adjustable end-cushioning to absorb the kinetic energy of this long stroke—which the fixed rubber bumper on the MAL lacks—you should step up to the MBLC25X550-CM variant.
When sizing for force, stepping down to the 20mm bore yields 157N push at 0.5MPa, while stepping up to the 32mm bore provides 402N push at 0.5MPa. Because the 550mm stroke combined with the 10mm rod creates high susceptibility to side-load bending, you must use an external guide rail or a pivot mounting scheme to prevent rod damage. Furthermore, a plain MBL cylinder does not hold its position or load when air pressure is lost; the rod will drift, so an external rod lock or pilot-operated check valve is required for fail-safe load holding.
Upgrade checklist
- ✓ Order the MBL25X550-CM (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 MBL25X550-CM instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X550-CM FAQ
Yes, the MAL25X550-CM is discontinued. The exact drop-in replacement is the MBL25X550-CM, offering the same 25mm bore, 550mm stroke, G1/8 port, and CM round-end cover.
At 0.5MPa it provides 245N push and 206N pull force, 343N push at 0.7MPa, and a maximum theoretical force of 50kgf at 1.0MPa. Because this specific SKU lacks an -S magnet, it cannot accept a position sensor.
