About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X150U
The AirTAC MBLC63X150U is a double-acting aluminum mini cylinder engineered to move substantial masses with a 1558 N push force at 0.5 MPa. Driven by air through a G1/4 port, it uses a Ø16 carbon-steel rod with a 20 um hard-chrome plating to resist corrosion and scoring. The U suffix specifies a rigid flat-end back cover for straightforward inline mounting. Because this SKU lacks the -S magnet code, it cannot accept a CMSG, DMSG, or EMSG position sensor.
Unlike the base MBL which relies on a fixed rubber bumper, this MBLC variant features a screw-adjustable pneumatic cushion at both stroke ends. Tuning the needle decelerates the piston smoothly near the 150 mm travel limits, absorbing kinetic energy to protect the end covers on fast, heavy cycles. Its riveted rolling-packed aluminum barrel keeps the body compact and lightweight, while the heterogeneous two-way grease-retaining piston seal maintains lubrication for a 30-800 mm/s operating speed.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X150U Is Used
Pallet Transfer Stops
Halts 50 kg loaded pallets on a packaging line using 1558 N of push force, with the adjustable air cushion absorbing the kinetic energy to prevent end-cover damage during fast 150 mm strokes.
Injection Mold Ejection
Pushes finished plastic parts out of a molding die, utilizing the 2181 N thrust at 0.7 MPa and the smooth end-of-stroke deceleration to avoid marking hot plastic components.
Heavy Carton Flap Folding
Folds heavy cardboard flaps on a high-speed case erector, relying on the 1457 N pull force and the tunable cushion to cycle quietly at high frequency without jarring the machine frame.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X150U the Right Cylinder?
This 63 mm bore is the largest in the MBLC series, delivering 1558 N push and 1457 N pull at 0.5 MPa. If your payload is lighter, step down to the 50 mm bore, which yields 981 N push and 881 N pull at the same pressure. Since 63 mm is the maximum available diameter, you cannot step up further within this family. Choose this MBLC over the fixed-bumper MBL when your cycle times are fast and the moving mass is high enough that a rigid impact would damage the machine. Remember that the adjustable cushion only decelerates the piston near the ends; it is not a mechanical brake and will not hold a load in place if air pressure drops or the valve centers. For position holding without live air, install an external rod lock.
For a direct replacement, match the 63 mm bore, 150 mm stroke, G1/4 port, PT thread, U flat-end back cover, and no magnet. At 150 mm of travel, side-load stress on the 16 mm rod is moderate, but if you push heavier radial loads, consider using a CA or SDB pivot bracket to accommodate arcing motion instead of the rigid U 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 MBLC63X150U FAQ
At 0.5 MPa, this 63 mm bore cylinder provides 1558 N of push force and 1457 N of pull force. At 0.7 MPa, the push increases to 2181 N. The maximum theoretical force is 318 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa with a speed range of 30-800 mm/s.
The cushion is a screw-tunable pneumatic needle at both ends of the stroke. By adjusting the needle, you control the exhaust flow rate as the piston nears the end cap, creating a trapped air cushion that decelerates the load smoothly. This prevents harsh impacts on fast or heavy moves, outperforming the fixed rubber bumper of the standard MBL. It only decelerates near the stroke ends and does not lock or hold the load.
