This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X270SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X270SU 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 MAL25X270SU
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X270SU is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 270mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X270SU, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X270SU
The AirTAC MAL25X270SU is a discontinued double-acting aluminum mini round cylinder. It delivers 245 N of push force at 0.5 MPa and features a 270 mm stroke. The exact drop-in replacement is the MBL25X270SU, matching the 25 mm bore, force, G1/8 port, and flat-end U cover.
This legacy unit uses a fixed rubber bumper for end-of-stroke damping, whereas the current MBLC line offers an adjustable air cushion. The original MAL body uses threaded front and back covers, while the newer MBL features a riveted rolling-packed body. Because this SKU includes the -S magnet, position detection relied on older CS1-M or DS1-M switches; upgrading to the MBL means transitioning to the modern CMSG, DMSG, or EMSG sensor family.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X270SU 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 MBL25X270SU 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 MAL25X270SU Is Used
Pallet Transfer Gate
Pushes 25mm aluminum pallets through a diverting gate on a packaging conveyor using 245 N of push force at 0.5 MPa.
Positions printed circuit boards into a vision inspection fixture, utilizing the 270 mm stroke to clear the work area.
PCB Edge Guide Pusher
Folds small corrugated carton flaps prior to sealing, where the fixed rubber bumper safely absorbs the 30-800 mm/s cycle impact.

Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X270SU with MBL25X270SU
To replace the MAL25X270SU, order the MBL25X270SU. Verify your 25 mm bore, 270 mm stroke, and default PT tapered port threads. The U flat-end back cover provides rigid rear mounting. If you need to step down for lower force, the 20 mm bore provides 157 N push at 0.5 MPa. If you need more force, the 32 mm bore yields 402 N. Note that a plain cylinder drifts when air is lost; the bumper is not a lock, so use an external rod lock for vertical loads. At 270 mm stroke, the 10 mm rod has low side-load tolerance, requiring an external guide rail to prevent rod bending.
Upgrade checklist
- ✓ Order the MBL25X270SU (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 MBL25X270SU instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X270SU FAQ
Yes, the MAL25X270SU is discontinued. The exact drop-in replacement is the MBL25X270SU, which matches the 25 mm bore, 270 mm stroke, 245 N push force, G1/8 port, and U flat-end cover. The -S magnet on the new MBL uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M sensors.
The 25 mm bore cylinder uses a G1/8 port and a 10 mm rod with an M10x1.25 thread. At 0.5 MPa, it provides 245 N push and 206 N pull force. At 0.7 MPa, push is 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa.
