This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X90SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X90SU 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 MAL25X90SU
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X90SU is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 90mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X90SU, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X90SU
The AirTAC MAL25X90SU is a discontinued compact double-acting aluminum mini round cylinder. In this 25 mm bore configuration, it delivers 245 N of push force and 206 N of pull force at 0.5 MPa, utilizing a Ø10 mm carbon-steel rod with 20 um hard-chrome plating. The exact drop-in replacement is the MBL25X90SU, which matches the original stroke, porting, and output exactly.
This SKU includes a built-in magnet (-S) and a U flat-end back cover. The legacy MAL relied on threaded front and back covers on the barrel, whereas the modern MBL replacement features a riveted rolling-packed body. Additionally, the -S magnet on this old unit functions with the older CS1-M and DS1-M switches; upgrading to the MBL requires switching to the current CMSG, DMSG, or EMSG sensor family.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X90SU 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 MBL25X90SU 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 MAL25X90SU Is Used
PCB Depaneling Router
Pushes a 90 mm travel slide to separate routed circuit boards, utilizing the 245 N push force to cleanly snap pre-scored panels without stressing surface mounts.
Carton Flap Folder
Drives a compact folding arm 90 mm inward to close minor flaps on small packaging cartons, where the 206 N pull force reliably retracts the arm for the next box.
Lab Tube Ejection
Extends 90 mm to eject filled micro-centrifuge tubes from a processing carousel, applying just enough 0.5 MPa thrust to push them into a collection bin.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X90SU with MBL25X90SU
To replace the MAL25X90SU, order the MBL25X90SU. Verify your 25 mm bore, 90 mm stroke, G1/8 port, and PT thread form. Because this SKU includes the -S magnet, you must upgrade your sensors: the old CS1-M / DS1-M switches are replaced by CMSG / DMSG / EMSG units on the MBL. The U flat-end back cover provides rigid rear mounting, so ensure your framework handles straight alignment without articulation.
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. Note that the fixed rubber bumper softens end-of-stroke impact but is not an adjustable cushion; if your 90 mm cycle needs precise end-energy control, choose the current-line MBLC. Finally, a plain cylinder does not hold a load when air is lost—the rod drifts—so add an external rod lock for vertical or gravity-loaded applications.
Upgrade checklist
- ✓ Order the MBL25X90SU (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 MBL25X90SU instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X90SU FAQ
Yes, the MAL25X90SU is discontinued. The exact drop-in replacement is the MBL25X90SU, which provides the same 25 mm bore, 90 mm stroke, G1/8 port, and U flat-end mounting. The MBL body uses a riveted rolling-packed construction instead of the old threaded covers, and if you use the -S magnet, you must switch from CS1-M / DS1-M sensors to CMSG / DMSG / EMSG switches.
At 0.5 MPa, the 25 mm bore generates 245 N of push force and 206 N of pull force. At 0.7 MPa, push force is 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa. It operates on filtered air at 0.1-1.0 MPa, runs at 30-800 mm/s, and uses a fixed rubber bumper rather than an adjustable cushion.
