About the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X10SCA
The AirTAC MBL25X10SCA is a compact double-acting aluminum mini round cylinder engineered for exceptionally tight machine spaces. Delivering 245 N of push force at 0.5 MPa, this 25 mm bore, 10 mm stroke unit is purpose-built for short, rapid clamping tasks. Its riveted rolling-packed barrel crimps the front and rear covers directly to the tube, yielding a lightweight body that is not designed to be disassembled or rebuilt like a standard tie-rod cylinder.
This specific SKU features a built-in magnet (-S) for position detection via AirTAC CMSG, DMSG, or EMSG sensor switches, and a CA pivot back cover that swings on a pin to absorb arcing angular loads. The carbon-steel piston rod is hardened with 20 µm chrome plating for superior wear resistance, while a heterogeneous two-way piston seal retains grease for a long service life. The base end-of-stroke impact is absorbed by a fixed rubber bumper rather than an adjustable cushion.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X10SCA Is Used
PCB Edge Clamping
Uses the 245 N push force and 10 mm stroke to rapidly secure circuit boards during automated wave soldering without stressing the delicate substrate.
Carton Flap Tucking
Pivots via the CA clevis on a packaging line to tuck inner flaps at an angle, relying on the short 10 mm stroke for high-cycle speed.
Sensor Positioning
Leverages the -S magnet and DMSG electronic switch to confirm a 10 mm extension for placing optical sensors against a moving conveyor belt.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X10SCA the Right Cylinder?
For short-arc actuation requiring 245 N push at 0.5 MPa, this 25 mm bore is highly effective; step down to the 20 mm bore if your application only requires 157 N, or step up to the 32 mm bore when 402 N is needed to overcome higher friction. The CA clevis mount is ideal for pivoting mechanisms, but if your mechanism applies lateral stress on the 10 mm stroke, ensure an external guide supports the load. Because this is a double-acting cylinder, it cannot hold its position if air pressure is lost or the valve is centered—the rod will drift. To maintain a locked position without live pressure, integrate an external pilot-operated check valve. The exact replacement match is a 25 mm bore, 10 mm stroke, G1/8 port, PT thread, CA back cover, with a built-in magnet.
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 MBL25X10SCA FAQ
At 0.5 MPa it provides 245 N push and 206 N pull force. At 0.7 MPa the push increases to 343 N, with a maximum theoretical force of 50 kgf at 1.0 MPa. The operational speed ranges from 30-800 mm/s.
No, the base MBL features a fixed rubber bumper to soften the end-of-stroke impact, not an adjustable air cushion. If your short-stroke application requires adjustable cushioning for heavier moving masses, you must upgrade to the MBLC variant.
