This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X40UFA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X40UFA 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 MAL25X40UFA
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X40UFA is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 40mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X40UFA, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X40UFA
The AirTAC MAL25X40UFA is a discontinued compact double-acting aluminum mini round cylinder. It delivers 245 N of push force and 206 N of pull force at 0.5 MPa, making it suited for small-part actuation in tight spaces. The exact drop-in replacement is the MBL25X40UFA, which matches the original 25 mm bore, 40 mm stroke, G1/8 port, and FA flange mounting.
This legacy SKU features a U flat-end back cover for rigid rear mounting and uses a fixed rubber bumper for end-of-stroke damping. Because this specific configuration lacks the -S magnet option, it cannot support a position sensor. Upgrading to the MBL25X40UFA transitions you to a riveted rolling-packed body instead of the older threaded front and back covers, while the self-lubricating front-cover bearing guide and heterogeneous two-way grease-retaining piston seal carry over.

| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Fixed rubber bumper |
| Max standard stroke | Up to 500 mm |
Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X40UFA 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 MBL25X40UFA 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 MAL25X40UFA Is Used
PCB Depaneling Router
Provides 245 N of push force at 0.5 MPa to actuate the blade carriage on a compact PCB depaneling router, utilizing the 40 mm stroke to sever individual circuit boards cleanly.
Connector Insertion Press
Drives an IC socket insertion head with 206 N of pull force at 0.5 MPa, fitting easily into tight electronics assembly cells where the FA flange mounts rigidly to the sub-frame.
Package Diverter Arm
Actuates a short diverter gate on a conveyor system, using its 40 mm stroke to push lightweight packages onto a secondary packing lane without requiring side-load guides.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X40UFA with MBL25X40UFA
To replace the MAL25X40UFA, order the MBL25X40UFA, ensuring you keep the U flat-end cover, FA flange mount, and default PT thread. Since this SKU has no -S magnet, it cannot accept a sensor; if you need position detection, you must move to an MBL25X40S variant and update your switches from the legacy CS1-M / DS1-M to the modern CMSG / DMSG / EMSG family. If you need an adjustable air cushion instead of the fixed rubber bumper, look at the MBLC series.
For sizing flexibility, stepping down to the 20 mm bore drops the 0.5 MPa push force to 157 N, while stepping up to the 32 mm bore increases it to 402 N. Remember that a plain cylinder does not hold its load when air is lost—the rod drifts—and the bumper only softens the impact, so use an external rod lock for suspended loads.
Upgrade checklist
- ✓ Order the MBL25X40UFA (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 MBL25X40UFA instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X40UFA FAQ
Yes, the MAL series is end-of-life. The exact drop-in replacement is the MBL25X40UFA. It matches the original 25 mm bore, 40 mm stroke, 245 N push force at 0.5 MPa, G1/8 port, and FA flange mounting. The main upgrade is a riveted rolling-packed body replacing the older threaded covers.
At 0.5 MPa, it delivers 245 N push and 206 N pull; at 0.7 MPa, push is 343 N; and the maximum theoretical force is 50 kgf at 1.0 MPa. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor. If you need detection, switch to an MBL25X40S model and use CMSG, DMSG, or EMSG switches.
