This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X45SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X45SU 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 MAL25X45SU
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X45SU is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 45mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X45SU, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X45SU
The AirTAC MAL25X45SU is a discontinued compact double-acting aluminum mini round cylinder with a 25 mm bore and 45 mm stroke. It delivers 245 N of push force and 206 N of pull force at 0.5 MPa. The exact drop-in replacement is the MBL25X45SU, which matches the original bore, stroke, output force, G1/8 port, and U flat-end rear cover. You can install the MBL without modifying your existing mounting layout.
This legacy MAL unit features a threaded front and back cover assembly, whereas the current MBL utilizes a riveted rolling-packed body for equally robust performance. The piston relies on a heterogeneous two-way seal that retains grease, paired with a self-lubricating front-cover bearing guide. Its carbon-steel rod is plated with 20 um of hard chrome to resist wear. Because this SKU includes the -S magnet, it supports position detection using the older CS1-M or DS1-M switches; upgrading to the MBL means transitioning to the modern CMSG, DMSG, or EMSG sensor families.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X45SU 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 MBL25X45SU 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 MAL25X45SU Is Used
PCB Depaneling Ejector
Uses the 245 N push force at 0.5 MPa to eject cut circuit boards from a routing fixture without damaging delicate surface-mounted components.
Carton Flap Folder
Employs the 45 mm stroke to tuck minor flaps on small pharmaceutical cartons just before the sealing head applies adhesive.
Vial Sorting Diverter
Relies on the compact 25 mm body and U flat-end rigid mount to deflect empty glass vials into a rejection chute on a high-speed filling line.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X45SU with MBL25X45SU
To replace this MAL25X45SU, order the MBL25X45SU. Confirm your 25 mm bore, 45 mm stroke, G1/8 port, PT thread form, and the U flat-end back cover. The -S magnet transfers over, but you must swap any legacy CS1-M or DS1-M reed switches for current CMSG, DMSG, or EMSG sensors. If your application requires adjustable end-of-stroke cushioning, step up to the MBLC variant, as the MAL only provides a fixed rubber bumper. Note that a plain cylinder does not hold its position if air pressure drops; add an external rod lock or pilot-operated check valve for fail-safe load holding.
Verify your force requirements before ordering: the 25 mm bore yields 245 N push at 0.5 MPa. If you need less force, the neighboring 20 mm bore provides 157 N of push at 0.5 MPa. If you need more power, the 32 mm bore offers 402 N of push at 0.5 MPa.
Upgrade checklist
- ✓ Order the MBL25X45SU (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 MBL25X45SU instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X45SU FAQ
Yes, the MAL25X45SU is discontinued. The exact drop-in replacement is the MBL25X45SU, offering the same 25 mm bore, 45 mm stroke, G1/8 port, and U flat-end mounting. The MBL uses a riveted body instead of threaded covers, and its -S magnet requires CMSG, DMSG, or EMSG switches instead of the older CS1-M or DS1-M sensors.
At 0.5 MPa, the 25 mm bore provides 245 N of push force and 206 N of pull force. At 0.7 MPa, the push force increases to 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa.
