About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X225U
The AirTAC MBLC63X225U is a double-acting aluminum mini cylinder engineered to deliver 1558 N of push force and 1457 N of pull force at 0.5 MPa, peaking at a theoretical 318 kgf at 1.0 MPa. Driven by a Ø16mm carbon-steel rod with 20 µm hard-chrome plating, this 225mm stroke unit is built for substantial workloads within a compact framework. Because this specific SKU lacks the -S suffix, it has no internal magnet and cannot accept a CMSG, DMSG, or EMSG position sensor.
Unlike the standard MBL base which relies on a fixed rubber bumper, this MBLC variant features a screw-adjustable pneumatic air cushion at both ends. You tune the needle valve to smoothly decelerate the piston near the stroke limits, actively absorbing kinetic energy to protect the end covers on fast, heavy 63mm bore moves. The riveted rolling-packed aluminum barrel keeps the body light and slim for tight machine layouts, while the heterogeneous two-way grease-retaining piston seal ensures lasting lubrication across the 30-800 mm/s speed range.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X225U Is Used
Pallet Diverter Arm
Swings heavy pallets onto secondary packaging lines using 1558 N of thrust, with the tuned air cushion preventing the 225mm stroke from violently slamming the pivot mechanism at high cycle rates.
Injection Mold Ejector
Pushes finished molded parts out of heavy tooling where 50mm bore pull force is insufficient, relying on the 318 kgf maximum theoretical output and rigid U flat-end mounting for precise inline pushing.
Carton Case Packer
Actuates a folding flap on high-speed end-of-line packaging machinery, using the adjustable end cushions to rapidly cycle the 225mm stroke without shaking the lightweight aluminum frame apart.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X225U the Right Cylinder?
Select this 63mm bore when your application requires substantial thrust—such as 1558 N push at 0.5 MPa—and a 225mm travel distance. If you need less force to save space and air volume, the neighbouring 50mm bore offers 981 N of push force at 0.5 MPa. Since this is the largest standard mini round bore in the series, there is no larger step up; for even higher loads, you must transition to a different cylinder family entirely. Choose the MBLC over the base MBL when your cycle speeds are high or the moved mass is heavy enough that a fixed rubber bumper would fail to adequately absorb the end-of-stroke impact.
This SKU uses a U flat-end back cover for rigid, inline mounting and features PT (tapered) port threads with a G1/4 port size. The rod end thread is M14x1.5. At a 225mm stroke, a 63mm bore piston generates significant kinetic energy; while the adjustable cushion helps, you must manage side loads to prevent rod bending. For arcing or offset loads, switch to a CA pivot back cover or an SDB pivot bracket, use an external guide rail, or evaluate the MBLD double-rod cylinder. Note that the air cushion only decelerates the piston near the ends—it is not a brake, so the rod will drift if air pressure is lost or exhausted.
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 MBLC Aluminum Alloy Mini Air Cylinder MBLC63X225U FAQ
At 0.5 MPa, this 63mm bore double-acting cylinder provides 1558 N of push force and 1457 N of pull force. At 0.7 MPa, the push force is 2181 N. The maximum theoretical force is 318 kgf at 1.0 MPa. It operates at speeds from 30 to 800 mm/s.
No. Because the model code MBLC63X225U lacks the -S suffix, it was manufactured without a built-in magnet in the piston. Therefore, you cannot mount AirTAC CMSG, DMSG, or EMSG sensor switches to it for rod position detection.
