This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X170SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X170SU 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 MAL25X170SU
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X170SU is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 170mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X170SU, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X170SU
The AirTAC MAL25X170SU is a discontinued double-acting aluminum mini round cylinder with a 25mm bore and 170mm stroke. It delivers 245N of push force and 206N of pull force at 0.5 MPa, utilizing a G1/8 port and an M10x1.25 rod-end thread. The exact drop-in replacement is the MBL25X170SU, offering identical bore, stroke, output force, port size, and U flat-end mounting.
This legacy SKU features a built-in magnet (-S) that pairs with older CS1-M or DS1-M reed switches to track rod position. When upgrading to the MBL25X170SU, the sensor family changes to the current CMSG, DMSG, or EMSG series. Additionally, the original MAL uses threaded front and back covers on the barrel, whereas the modern MBL features a riveted rolling-packed body for enhanced structural rigidity. Both designs rely on a fixed rubber bumper rather than an adjustable air cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X170SU 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 MBL25X170SU 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 MAL25X170SU Is Used
PCB Depaneling Router
Provides 245N of push at 0.5 MPa to separate routed circuit boards, using the 170mm stroke to clear the cutting spindle during automated tool changes.
Pouch Sealing Jaw
Actuates a sealing jaw on a vertical form-fill-seal machine, where the 206N pull force reliably retracts the mechanism against spring tension in tight packaging spaces.
Carton Flap Folder
Folds minor flaps on small retail packaging lines, utilizing the U flat-end cover for rigid rear mounting and the -S magnet to confirm flap closure timing.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X170SU with MBL25X170SU
To replace the MAL25X170SU, order the MBL25X170SU and verify your setup uses a PT tapered G1/8 port, a flat-end U back cover, and a CS1-M or DS1-M sensor (which must be swapped to a CMSG, DMSG, or EMSG switch on the new unit). If your application requires less force, step down to a 20mm bore providing 157N push at 0.5 MPa; if you need more power, step up to a 32mm bore yielding 402N push. Note that a plain MAL or MBL does not hold its load when air pressure drops, as the rod drifts without a lock. If end-of-stroke impact damping is insufficient with the fixed rubber bumper, consider the current-line MBLC which adds an adjustable air cushion. Because this 170mm stroke exceeds 300mm, the 10mm rod has low side-load tolerance; use an external guide rail or a pivot mount to prevent rod bending.
Upgrade checklist
- ✓ Order the MBL25X170SU (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 MBL25X170SU instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X170SU FAQ
Yes, the MAL25X170SU is discontinued. The exact drop-in replacement is the MBL25X170SU, which matches the 25mm bore, 170mm stroke, G1/8 port, U flat-end cover, and 50 kgf maximum force. You must update your sensors from the legacy CS1-M/DS1-M to the modern CMSG/DMSG/EMSG family.
At 0.5 MPa, this double-acting cylinder provides 245N push and 206N pull force, increasing to 343N push at 0.7 MPa, with a theoretical maximum of 50 kgf at 1.0 MPa. It uses a fixed rubber bumper for end-of-stroke damping, not an adjustable cushion.
