About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X30U
The AirTAC MBLC63X30U is a double-acting aluminum mini cylinder engineered for high-force actuation within a compact footprint. Generating 1558 N of push force and 1457 N of pull force at 0.5 MPa, this 63 mm bore unit drives heavy loads over a short 30 mm stroke. The defining feature over the base MBL series is the screw-adjustable pneumatic cushion at both stroke ends. By tuning the needle valves, you decelerate the piston smoothly near the covers, significantly reducing impact shock, mechanical noise, and vibration during high-speed or heavy-mass cycling.
This specific configuration utilizes a U flat-end back cover for rigid, inline mounting. The riveted rolling-packed aluminum barrel keeps the body lightweight while ensuring structural integrity under pressure. Inside, a heterogeneous two-way grease-retaining piston seal maintains optimal lubrication over the 30-800 mm/s speed range, and the Ø16 mm carbon-steel rod features 20 µm hard-chrome plating for wear resistance. Note that this SKU lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensors without modification.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X30U Is Used
Short-Stroke Stamping
Delivers 1558 N of force at 0.5 MPa to seat bearings or stamp small metal components in tight mechanical assemblies without overwhelming the machine frame.
Heavy Pallet Stops
Acts as a robust stop gate for loaded pallets on a packaging line, using its tunable air cushion to absorb the momentum of arriving goods smoothly.
PCB Test Fixtures
Provides the high clamping pressure needed to secure circuit boards during automated ICT testing, cycling rapidly with minimal end-cover impact.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X30U the Right Cylinder?
Selecting the MBLC63X30U is ideal when your application requires maximum thrust in a miniature envelope but only needs a 30 mm travel. If you need to step down, the 50 mm bore neighbor provides 981 N of push force at 0.5 MPa, which may suffice for lighter payloads while saving space. As the largest standard size in this series, there is no larger neighbor to step up to within the MBL family; if 1558 N is insufficient, you would need to transition to a larger ISO 15552 profile cylinder. Choose this MBLC variant over the fixed rubber bumper of the standard MBL when your cycle rates are high or the moved mass is substantial enough that a passive bumper would degrade prematurely. Keep in mind that the adjustable air cushion only decelerates the piston near the end of travel; it is not a brake and will not hold the load in place if air pressure is lost or the valve centers. For position holding without live air, an external rod lock or pilot-operated check valve is required. This SKU features a G1/4 port, PT thread form, M14x1.5 rod-end thread, and a U flat-end rear cover.
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 MBLC63X30U FAQ
At 0.5 MPa, this 63 mm bore cylinder outputs 1558 N of push force and 1457 N of pull force. At 0.7 MPa, push increases to 2181 N, with a theoretical maximum of 318 kgf at 1.0 MPa. It uses a Ø16 mm carbon-steel rod with an M14x1.5 rod-end thread and a G1/4 port.
The MBLC features a screw-adjustable air cushion at both ends, allowing you to tune the end-of-stroke deceleration to protect the end covers when moving heavy loads at high speeds, unlike the fixed rubber bumper in the MBL. However, this cushion is not a locking mechanism; the cylinder will drift if air is lost. Additionally, this specific SKU does not have a built-in magnet, so it cannot be used with CMSG, DMSG, or EMSG sensor switches.
