This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X135SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X135SU 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 MAL25X135SU
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X135SU is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 135mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X135SU, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X135SU
The AirTAC MAL25X135SU is a discontinued compact double-acting aluminum mini round cylinder. Delivering 245 N of push force and 206 N of pull force at 0.5 MPa, it uses a 25 mm bore and 135 mm stroke. The exact drop-in replacement is the MBL25X135SU, which matches the bore, stroke, output force, G1/8 port, and U flat-end back cover. You can order the current MBL series to keep your machine running without modifying the mounting footprint.
This legacy SKU features a built-in magnet (-S) for position detection. On the original MAL, this magnet pairs with older CS1-M or DS1-M reed switches, whereas the modern MBL replacement requires CMSG, DMSG, or EMSG sensors. The original MAL body used threaded front and rear covers, while the upgraded MBL features a riveted rolling-packed body for enhanced structural integrity. Both designs rely on a fixed rubber bumper for end-of-stroke deceleration rather than an adjustable air cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X135SU 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 MBL25X135SU 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 MAL25X135SU Is Used
PCB Component Placement
Uses the 245 N push force at 0.5 MPa to press electronic connectors onto circuit boards within tight assembly machinery.
Packaging Flap Folding
The 135 mm stroke provides the exact reach needed to fold cardboard flaps on small carton packaging lines.
Lab Tube Ejection
Leverages the 206 N pull force to retract a gripper and eject filled sample tubes from a diagnostic carousel.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X135SU with MBL25X135SU
To replace the MAL25X135SU, order the MBL25X135SU. Confirm your 25 mm bore, 135 mm stroke, Ø10 mm rod with M10x1.25 thread, and the default PT tapered port thread. This SKU includes the U flat-end back cover for rigid rear mounting and the -S magnet. Because the -S magnet is present, note that your old CS1-M or DS1-M switches must be upgraded to CMSG, DMSG, or EMSG sensors to fit the MBL body. If you need to adjust force, stepping down to the 20 mm bore yields 157 N push at 0.5 MPa, while stepping up to the 32 mm bore provides 402 N push at 0.5 MPa.
With a 135 mm stroke, the 10 mm rod is susceptible to bending under lateral stress. Use an external guide rail or a pivot mounting accessory to support the load and prevent side-load damage. Remember that this cylinder relies on a fixed rubber bumper, not an adjustable cushion; if your application demands precise end-stroke deceleration, look at the MBLC variant on the current line. Finally, a plain MBL does not hold its load when air pressure drops; install an external rod lock or pilot-operated check valve if position holding is critical.
Upgrade checklist
- ✓ Order the MBL25X135SU (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 MBL25X135SU instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X135SU FAQ
Yes, the MAL25X135SU is discontinued. The exact drop-in replacement is the MBL25X135SU, which offers the same 25 mm bore, 135 mm stroke, G1/8 port, U flat-end cover, and mounting dimensions. You must upgrade your position sensors, as the MBL uses CMSG, DMSG, or EMSG switches instead of the older CS1-M or DS1-M models.
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 is 343 N, with a maximum theoretical force of 50 kgf at 1.0 MPa. It features a 10 mm rod, an M10x1.25 rod-end thread, a G1/8 port, and operates at speeds between 30 and 800 mm/s.
