About the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X30SCA
The AirTAC MBL25X30SCA is a double-acting aluminum mini round cylinder engineered for tight machine spaces. With a 25mm bore and 30mm stroke, it generates 245N of push force and 206N of pull force at 0.5 MPa. The riveted rolling-packed barrel crimps the covers directly to the tube, yielding a lighter, compact body that is not designed to be disassembled like a tie-rod cylinder.
This specific SKU includes a built-in magnet (-S) for pairing with CMSG reed or DMSG and EMSG electronic sensor switches to track rod position. It features a CA pivot (clevis) back cover that swings on a pin, making it ideal for arcing or angular loads. The Ø10mm carbon-steel rod is hardened with 20µm chrome plating for wear resistance, and the heterogeneous two-way piston seal retains grease for a long service life.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X30SCA Is Used
PCB Router Traversing
Drives a short 30mm arcing pivot on a PCB depaneling router, using the CA clevis to maintain alignment while routing traces with 245N of push force.
Lathe Tool Turret Index
Pivots a small lathe tool turret into cutting position, where the built-in magnet triggers a DMSG solid-state sensor to confirm tool engagement.
Pouch Spout Insertion
Swings a spout feeder into a packaging line to insert nozzles into pouches, leveraging the compact riveted body to fit between narrow guide rails.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X30SCA the Right Cylinder?
If you need less force, step down to the Ø20 bore, which provides 157N push at 0.5 MPa. For heavier demands, step up to the Ø32 bore, which outputs 402N push. Because this is a base MBL, end-of-stroke deceleration relies on a fixed rubber bumper rather than an adjustable air cushion; choose the MBLC variant if your application requires screw-adjustable cushioning for heavier moving masses.
Note that a plain rubber bumper only softens end-of-stroke impact; it does not hold the load if air pressure drops. For position holding without live pressure, add an external rod lock or pilot-operated check valve. This SKU uses a G1/8 port with PT tapered threading, a 30mm stroke, and the CA pivot back cover. If you need to prevent rod rotation on a longer stroke, consider the MBLD double-rod type.
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 MBL25X30SCA FAQ
This cylinder provides 245N push and 206N pull at 0.5 MPa, 343N push at 0.7 MPa, and a maximum theoretical force of 50 kgf at 1.0 MPa. It uses a G1/8 port with PT tapered threading.
No, the base MBL uses a fixed rubber bumper to soften end-of-stroke impacts, not an adjustable cushion screw. If you need adjustable air cushioning for faster cycling or heavier loads, select the MBLC variant.
