About the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X10SU
The AirTAC MBL25X10SU is a compact double-acting aluminum mini round cylinder engineered for extremely tight machine spaces. Operating with a 25mm bore and a short 10mm stroke, it provides a push force of 245 N and a pull force of 206 N at 0.5 MPa. The riveted rolling-packed barrel crimps the front and rear covers directly to the tube, creating a lightweight body that is not designed to be disassembled or rebuilt like a standard tie-rod cylinder.
This specific SKU includes a built-in magnet (-S) for position detection via AirTAC CMSG reed or DMSG and EMSG solid-state sensor switches. It features a U flat-end back cover for rigid fixed mounting and uses a carbon steel piston rod with a 20 um hard-chrome plating to resist wear and corrosion. The cylinder relies on a fixed rubber bumper to soften end-of-stroke impacts rather than an adjustable air cushion.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X10SU Is Used
PCB Connector Insertion
Provides a precise 10mm stroke and 245N push force to seat delicate pin headers into printed circuit boards without damaging surrounding components.
Pharmaceutical Carton Flap Fold
Uses the compact 25mm bore and DMSG sensor feedback to execute short, rapid folding motions on small medical packaging boxes in confined spaces.
Small Part Ejection
Delivers 206N pull force to retract a tiny ejector pin in a stamping die, relying on the rigid U flat-end mount to maintain alignment.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X10SU the Right Cylinder?
Choose this 25mm bore when an application requires 245 N of push force at 0.5 MPa within a very small footprint. If your assembly needs less force, stepping down to the 20mm bore yields 157 N; if you require greater thrust, stepping up to the 32mm bore provides 402 N. The 10mm stroke is ideal for micro-clamping or short ejection tasks. For operations needing end-of-stroke deceleration for heavier moving loads, consider the MBLC variant which features an adjustable air cushion instead of the standard fixed rubber bumper.
This model includes the -S magnet for CMSG, DMSG, or EMSG sensors, a U flat-end back cover, and a default PT port thread. Because it is a double-acting cylinder, it does not hold its position or load if air pressure is lost or the valve is centered; the rod will drift. Use an external rod lock or pilot-operated check valve if the load must be held safely without live pressure.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (LB / FA / SDB) and back cover (CA pivot / U flat-end).
- check Installation by qualified personnel per AirTAC docs.
Airtac MBL Aluminum Alloy Mini Cylinder MBL25X10SU FAQ
At 0.5 MPa, the push force is 245 N and the pull force is 206 N. At 0.7 MPa, the push force increases to 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa. The operating speed ranges from 30-800 mm/s.
No, the base MBL uses a fixed rubber bumper to soften end-of-stroke impact, not an adjustable cushion (you would need the MBLC variant for adjustable air cushioning). Additionally, the rubber bumper is not a lock; the cylinder cannot hold a load if air pressure is lost, so an external rod lock is required for position holding.
