This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X540SCM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X540SCM 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 MAL25X540SCM

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X540SCM
The AirTAC MAL25X540SCM is a discontinued double-acting aluminum mini round cylinder featuring a 25mm bore and a 540mm stroke. Because the 540mm stroke exceeds the 500mm standard maximum, this unit was produced as a made-to-order item. In its force class, it delivers a push thrust of 245 N and a pull of 206 N at 0.5 MPa. The exact drop-in replacement is the MBL25X540SCM, which matches the original bore, stroke, output force, G1/8 port, and mounting interface perfectly.
This specific SKU includes a built-in magnet (-S) for position sensing and a CM round-end back cover. On the legacy MAL, the -S magnet functions with older CS1-M or DS1-M reed switches, whereas the MBL replacement transitions to the current CMSG, DMSG, or EMSG sensor families. Additionally, the old MAL utilized threaded front and back covers on the barrel, while the modern MBL features a riveted rolling-packed body for enhanced structural integrity. The piston relies on a heterogeneous two-way seal that retains grease, and the 10mm carbon-steel rod is coated with 20 μm hard chrome for wear resistance.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X540SCM 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 MBL25X540SCM 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 MAL25X540SCM Is Used
Textile Yarn Guide
Drives a traversing yarn guide across a 540mm span in a weaving loom, utilizing the 245N push force at 0.5 MPa to tension and direct delicate threads without snapping them.
PCB Edge Conveyor
Actuates a pop-up transfer gate on a PCB assembly conveyor, where the CM round-end back cover pivots smoothly to accommodate slight mechanical misalignment during long-stroke extension.
Carton Flap Folder
Extends a folding arm along a packaging line to tuck carton flaps, relying on the self-lubricating front-cover bearing guide to maintain smooth operation over a 540mm travel distance.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X540SCM with MBL25X540SCM
To replace the MAL25X540SCM, order the MBL25X540SCM. Verify your setup accommodates the PT tapered port thread, the M10x1.25 rod-end thread, and the CM round-end back cover, which is designed to accept a clevis or rod-end knuckle for pivoting articulation. Because this SKU includes the -S magnet, you must also upgrade your position sensors from the legacy CS1-M/DS1-M series to the modern CMSG/DMSG/EMSG switches used by the MBL.
When sizing this cylinder, note that stepping down to the 20mm bore reduces the 0.5 MPa push force to 157 N, while stepping up to the 32mm bore increases it to 402 N. At 540mm of stroke, the 10mm rod is highly susceptible to bending under side loads; you must use an external guide rail or a pivoting CM knuckle mount to prevent premature seal failure. Also, remember that the fixed rubber bumper only softens end-of-stroke impact and does not hold the load if air pressure drops—use a pilot-operated check valve for position holding. If your application requires adjustable end-of-stroke cushioning, the MAL cannot provide it, but the current-line MBLC variant offers this feature.
Upgrade checklist
- ✓ Order the MBL25X540SCM (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 MBL25X540SCM instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X540SCM FAQ
Yes, the MAL25X540SCM is discontinued. The exact drop-in replacement is the MBL25X540SCM, which matches the 25mm bore, 540mm stroke, G1/8 port, and CM round-end mounting. You must update your sensors, as the MAL -S magnet works with CS1-M/DS1-M switches, while the MBL uses CMSG/DMSG/EMSG sensors.
At 0.5 MPa, this 25mm bore cylinder provides 245 N of push force and 206 N of pull force. At 0.7 MPa, the push force is 343 N, with a theoretical maximum of 50 kgf at 1.0 MPa. It uses a fixed rubber bumper for end-of-stroke impact absorption and does not feature adjustable cushioning; if adjustable cushioning is required, look at the MBLC variant.
