About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X400U
The AirTAC MBLC63X400U is a double-acting mini round cylinder engineered for substantial linear thrust, delivering 1558 N push and 1457 N pull at 0.5 MPa. A 400 mm stroke provides the extended travel needed for indexing, lifting, or pushing heavy pallets in compact machinery. Its defining feature over the base MBL is a screw-adjustable pneumatic cushion at both ends, which decelerates the piston smoothly near stroke extremes to reduce end-cover impact, mechanical vibration, and noise during high-speed or heavy-mass cycles. This cushion is strictly for end-of-stroke deceleration and does not function as a load lock or brake.
Constructed with a riveted rolling-packed aluminum barrel for a lightweight yet rigid profile, this 63 mm bore unit relies on a heterogeneous two-way grease-retaining piston seal paired with a 20 µm hard-chrome plated carbon-steel rod. The U designation specifies a flat-end back cover for rigid rear mounting. Because this specific SKU lacks the S magnet code, it cannot accept CMSG, DMSG, or EMSG sensor switches for position detection. Operating pressure spans 0.15-1.0 MPa, with a speed range of 30-800 mm/s.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X400U Is Used
Pallet Push-Off Station
Provides the 1558 N push force required to index heavy loaded pallets off a conveyor line, with the adjustable cushion absorbing the deceleration of the 400 mm stroke.
Palletizer Diverter Arm
Drives a heavy diverter mechanism across a 400 mm gap, relying on the tunable air cushion to prevent end-cover impact during high-speed routing of goods.
Vertical Carton Ejector
Ejects stacked packaging from a machine bed, utilizing the 1457 N pull force for retraction while the cushion needle regulates the downward speed to protect the tooling.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X400U the Right Cylinder?
Select this 63 mm bore when your application requires high force, as it generates 1558 N of push at 0.5 MPa. If you need less thrust and a smaller footprint, step down to the 50 mm bore, which provides 981 N of push at 0.5 MPa. As this is the largest standard MBL/MBLC bore size, stepping up would require migrating to a different ISO 15552 cylinder family. Choose this MBLC variant over the fixed-bumper MBL specifically when moving heavy loads at high velocities or cycling frequently, where a fixed rubber bumper would degrade rapidly.
For a drop-in replacement, match the 63 mm bore, 400 mm stroke, G1/4 port, PT thread, U flat-end back cover, and the absence of a magnet. Because the 400 mm stroke is substantial, the Ø16 mm rod has a higher susceptibility to side-load bending; to manage this, utilize an external guide rail, select a CA or SDB pivot bracket for arcing loads, or consider the MBLD double-rod cylinder to prevent rod deflection. Note that a plain MBLC will not hold position if air pressure is lost or the valve centers—the rod will drift unless an external pilot-operated check valve or rod lock is installed.
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 MBLC63X400U FAQ
At 0.5 MPa, this 63 mm bore cylinder generates 1558 N of push force and 1457 N of pull force. At 0.7 MPa, push increases to 2181 N. The maximum theoretical force is 318 kgf at 1.0 MPa. It uses a G1/4 port, a Ø16 mm rod, and an M14x1.5 rod-end thread.
No, this specific SKU lacks the built-in magnet (indicated by the absence of the S code in the model number), so it cannot accept AirTAC CMSG, DMSG, or EMSG sensor switches. If position detection is required, you must select the MBLC63X400S variant.
