About the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X250-CA
The AirTAC MBL25X250-CA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It generates 245 N of push force and 206 N of pull force at 0.5 MPa, making this 250 mm stroke unit well-suited for mid-range linear actuation. The riveted rolling-packed barrel design keeps the body light and small, fundamentally differing from heavy tie-rod cylinders because it is built as a permanently crimped assembly rather than a rebuildable housing.
This specific SKU features a CA pivot (clevis) back cover, allowing the cylinder body to swing freely on a pin to accommodate arcing or angular loads during movement. It lacks the -S magnet suffix, meaning it cannot accept a CMSG, DMSG, or EMSG position sensor switch. Internally, a heterogeneous two-way piston seal retains grease for long service life, while the Ø10 mm carbon steel piston rod features 20 μm hard-chrome plating to resist wear and corrosion.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X250-CA Is Used
PCB Conveyor Diversion
Pushes lightweight routing gates on SMT lines using 245 N at 0.5 MPa, where the CA pivot absorbs slight angular misalignment common in conveyor frames.
Carton Flap Folding
Folds small cardboard flaps during case packing, utilizing the 250 mm stroke to clear tall carton profiles before the sealing station.
Sample Tube Transfer
Moves diagnostic sample racks between testing modules, benefiting from the lightweight aluminum body in high-speed lab automation.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X250-CA the Right Cylinder?
Stepping down to the 20 mm bore drops the 0.5 MPa push force to 157 N, whereas stepping up to the 32 mm bore raises it to 402 N. If your cycle ends violently and the fixed rubber bumper causes shock, switch to the MBLC variant for an adjustable air cushion. Because this is a 250 mm stroke on a small Ø10 mm rod, long unsupported strokes have low side-load tolerance; an external guide or the MBLD double-rod type is recommended to prevent rod-bearing bending. Note that the rubber bumper only softens end-of-stroke impact and does not hold the load—if air pressure is lost or the valve is centred, the rod will drift and drop, requiring an external rod lock or pilot-operated check valve to maintain position. Replacement match: 25 mm bore, 250 mm stroke, G1/8 port, PT thread, CA back cover, no 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 MBL25X250-CA FAQ
At 0.5 MPa, this 25 mm bore cylinder provides 245 N push and 206 N pull force. At 0.7 MPa, the push force is 343 N, with a theoretical maximum of 50 kgf at 1.0 MPa. The operating speed ranges from 30-800 mm/s.
No. This base MBL model uses a fixed rubber bumper, not an adjustable air cushion (you must choose the MBLC variant for that). Additionally, because this SKU lacks the -S suffix, it has no built-in magnet and cannot accept CMSG, DMSG, or EMSG sensor switches.
