This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X550-S-CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X550-S-CA 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-S-CA
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X550-S-CA 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-S-CA, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X550-S-CA
The AirTAC MAL25X550-S-CA is a discontinued double-acting aluminum mini round cylinder with a 25 mm bore and a 550 mm non-standard stroke. It delivers 245 N of push force at 0.5 MPa. The exact drop-in replacement is the MBL25X550-S-CA, matching the bore, stroke, G1/8 port, and CA pivot mounting. This 550 mm length exceeds the 500 mm standard maximum, so it is produced as a made-to-order item.
This SKU includes a built-in magnet (-S) and a CA pivot clevis back cover. The legacy MAL uses threaded front and back covers, whereas the modern MBL features a riveted rolling-packed body. Because this unit has the -S magnet, it operates with the older CS1-M / DS1-M switches; upgrading to the MBL means switching to the current CMSG / DMSG / EMSG sensor family. The piston relies on a heterogeneous two-way seal that retains grease, and the carbon-steel rod has a 20 um hard-chrome plating to resist wear.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X550-S-CA 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-S-CA 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-S-CA Is Used
Carton Flap Folder
Uses the 245 N push force at 0.5 MPa to tuck heavy cardboard flaps on a packaging line, with the 550 mm stroke reaching across a wide format box.
Textile Beam Indexer
Leverages the CA pivot clevis to swing a yarn guide into position, absorbing angular misalignment while traversing the full 550 mm length.
Pallet Wrapper Arm
Extends a film carriage carriage out 550 mm around a pallet base, relying on the 343 N push at 0.7 MPa to overcome guide friction.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X550-S-CA with MBL25X550-S-CA
To replace this MAL, order the MBL25X550-S-CA. Confirm the 25 mm bore, 550 mm stroke, G1/8 port, PT thread, CA pivot back cover, and magnet are retained. The CA clevis allows the body to swing on a pin, which is essential for accommodating arcing loads over this long 550 mm travel. If your application requires adjustable end-cushioning to absorb kinetic energy, the fixed rubber bumper on this MAL cannot be adjusted; you would need to step up to the current MBLC line. Additionally, a plain cylinder does not hold its position if air pressure drops—the rod will drift. Use an external rod lock or pilot-operated check valve for load holding.
When sizing, verify if 245 N push at 0.5 MPa is sufficient. Stepping down to a 20 mm bore drops the force to 157 N, while stepping up to a 32 mm bore increases it to 402 N. Because the stroke is 550 mm, the 10 mm rod has low side-load tolerance. You must use an external guide rail to prevent rod bending, relying on the CA pivot to self-align any minor angular offset.
Upgrade checklist
- ✓ Order the MBL25X550-S-CA (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-S-CA instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X550-S-CA FAQ
Yes, the MAL series is end-of-life. The exact drop-in replacement is the MBL25X550-S-CA. It matches the 25 mm bore, 550 mm stroke, G1/8 port, and CA pivot mounting. Note that the -S magnet on the MAL works with CS1-M / DS1-M switches, while the MBL replacement requires CMSG / DMSG / EMSG sensors.
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 maximum theoretical force is 50 kgf at 1.0 MPa. The 550 mm stroke exceeds the 500 mm standard maximum, making it a non-standard, made-to-order length.
