This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X330SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X330SU 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 MAL25X330SU
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X330SU is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 330mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X330SU, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X330SU
The AirTAC MAL25X330SU is a discontinued double-acting aluminum mini round cylinder with a 25 mm bore and 330 mm stroke. It delivers 245 N of push force at 0.5 MPa. The exact drop-in replacement is the MBL25X330SU, which matches the bore, stroke, output force, G1/8 port, and U flat-end mounting. You can swap them directly without altering your machine layout.
This legacy unit features a built-in magnet (-S) for position sensing. On the MAL, this magnet pairs with older CS1-M or DS1-M switches, whereas the modern MBL replacement utilizes current CMSG, DMSG, or EMSG sensors. The original MAL body uses threaded front and back covers, while the upgraded MBL features a riveted rolling-packed body for structural rigidity. Both share a fixed rubber bumper and a self-lubricating front-cover bearing guide that supports the 10 mm carbon-steel hard-chrome rod.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X330SU 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 MBL25X330SU 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 MAL25X330SU Is Used
PCB Depaneling Router
Extends a cutting tool guide across a 330 mm span, using 245 N of push force to score and separate composite circuit boards without stressing the substrate.
Carton Flap Folder
Actuates a folding arm on a packaging conveyor, relying on the U flat-end back cover for rigid rear mounting while retracting with 206 N of pull force.
IC Tube Transfer
Pushes loaded semiconductor handling tubes into a testing nest, where the -S magnet triggers a CS1-M sensor to confirm the 330 mm extend position.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X330SU with MBL25X330SU
To replace the MAL25X330SU, order the MBL25X330SU. Confirm your 25 mm bore, 330 mm stroke, PT thread, and the U flat-end back cover. Because this SKU includes the -S magnet, note that your legacy CS1-M or DS1-M switches will need upgrading to CMSG, DMSG, or EMSG sensors on the new MBL body. If your application requires adjustable cushioning instead of the standard fixed rubber bumper, look at the MBLC variant on the current line.
When sizing, verify if 245 N push at 0.5 MPa is sufficient. If you need less force, step down to the 20 mm bore (157 N push); if you need more, step up to the 32 mm bore (402 N push). A 330 mm stroke on a 10 mm rod demands careful alignment. The small rod diameter offers low side-load tolerance, so use an external guide rail to prevent rod bending. Remember that a plain cylinder does not hold its load when air is lost; the bumper only softens end-of-stroke impact, so add a pilot-operated check valve if drift is unacceptable.
Upgrade checklist
- ✓ Order the MBL25X330SU (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 MBL25X330SU instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X330SU FAQ
Yes, the MAL25X330SU is discontinued. The exact drop-in replacement is the MBL25X330SU, which provides the same 25 mm bore, 330 mm stroke, G1/8 port, and U flat-end mounting. The main difference is the body construction: the MAL uses threaded covers, while the MBL uses a riveted rolling-packed body.
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. It operates between 0.1-1.0 MPa with a speed range of 30-800 mm/s.
