This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X550SCM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X550SCM 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 MAL25X550SCM
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X550SCM 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 MBL25X550SCM, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X550SCM
The AirTAC MAL25X550SCM is a discontinued double-acting aluminum mini round cylinder with a 25mm bore and a 550mm stroke. Because the stroke exceeds the 500mm standard limit, this is a made-to-order unit. It delivers 245N of push force and 206N of pull force at 0.5 MPa. The exact drop-in replacement is the MBL25X550SCM, which matches the bore, stroke, force, G1/8 port, and CM round-end mounting exactly.
Two engineering details stand out on this legacy unit. First, the original MAL uses threaded front and back covers on the barrel, whereas the modern MBL replacement features a riveted rolling-packed body for greater structural rigidity. Second, this SKU includes a magnet (-S) for position sensing; on the MAL it pairs with older CS1-M or DS1-M switches, but the MBL successor requires the current CMSG, DMSG, or EMSG sensor family.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X550SCM 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 MBL25X550SCM 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 MAL25X550SCM Is Used
PCB Conveyor Sorting
Pushes populated circuit boards across a 550mm transfer gap with 245N force at 0.5 MPa, fitting within tight electronics assembly machinery.
Carton Flap Folding
Extends 550mm to fold long packaging flaps on small cartons, relying on the CM round-end back cover to accommodate slight alignment shifts.
Textile Yarn Guiding
Cycles continuously to shift a yarn guide carriage across a 550mm weaving width, benefiting from the 30-800 mm/s speed range.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X550SCM with MBL25X550SCM
To replace the MAL25X550SCM, order the MBL25X550SCM. Verify your 10mm rod and M10x1.25 rod-end thread, the default PT tapered port, and the CM round-end back cover. Because the 550mm stroke is non-standard, expect a made-to-order lead time. If your application needs end-of-stroke deceleration, remember the MAL only has a fixed rubber bumper; the current line offers the MBLC variant with an adjustable air cushion.
When sizing, check the neighboring bores to ensure 245N push at 0.5 MPa is correct. Stepping down to the 20mm bore drops force to 157N, while stepping up to the 32mm bore increases it to 402N. A plain cylinder does not hold a load if air pressure drops—the rod drifts—so add an external rod lock for vertical holding. Finally, a 550mm stroke on a 10mm rod is highly susceptible to side-load bending; use an external guide rail or a pivot mount to prevent rod damage.
Upgrade checklist
- ✓ Order the MBL25X550SCM (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 MBL25X550SCM instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X550SCM FAQ
Yes, the MAL25X550SCM is discontinued. The exact drop-in replacement is the MBL25X550SCM, offering the same 25mm bore, 550mm stroke, force, G1/8 port, and CM round-end mounting. Note that the MBL uses a riveted body instead of threaded covers, and if you use the -S magnet, you must upgrade from CS1-M/DS1-M switches to the CMSG/DMSG/EMSG family.
At 0.5 MPa, the push force is 245N and the pull force is 206N. At 0.7 MPa, the push force is 343N. The maximum theoretical force is 50 kgf at 1.0 MPa. This unit uses a fixed rubber bumper, not an adjustable cushion.
