About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X175U
The AirTAC MBLC63X175U is a double-acting aluminum mini cylinder engineered for heavy-duty compact actuation. It delivers 1558 N of push force and 1457 N of pull force at 0.5 MPa, peaking at a 318 kgf theoretical maximum at 1.0 MPa. The 175 mm stroke excels in mid-range linear positioning tasks. Unlike the base MBL series, this variant features a screw-adjustable pneumatic air cushion at both stroke ends. This lets you dial in deceleration to smoothly brake heavier 63 mm bore loads, actively protecting the end covers from impact wear during high-frequency cycling.
The U suffix indicates a rigid flat-end rear cover for straightforward fixed mounting. Built with a riveted rolling-packed aluminum barrel, the body remains lightweight for tight machine cavities while avoiding the bulk of tie-rod construction. The 16 mm carbon-steel rod features 20 um hard-chrome plating to resist scoring, paired with a heterogeneous two-way grease-retaining piston seal that maintains lubrication over long service intervals. Note that because this SKU lacks the -S magnet code, it cannot host CMSG, DMSG, or EMSG position sensors.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X175U Is Used
Pallet Transfer Indexing
Drives a heavy pallet transfer carriage over 175 mm. The tunable air cushion brakes the 1558 N push force smoothly at stroke end, preventing load shift and end-cover damage during fast 30-800 mm/s cycling.
Injection Mold Ejection
Ejects dense plastic injection-molded parts from a press. The 63 mm bore supplies 1457 N pull at 0.5 MPa to retract the ejector pin, while the adjustable cushion softens the rapid retraction stop.
Carton Case Erector
Folds and squares heavy corrugated carton blanks in continuous packaging lines. The 175 mm stroke provides the exact travel needed, and the cushion needle dials out harsh slamming on high-frequency flap closures.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X175U the Right Cylinder?
At 0.5 MPa, this 63 mm bore generates 1558 N push and 1457 N pull. If you need less force, stepping down to the 50 mm bore yields 981 N push and 881 N pull. Since 63 mm is the largest standard MBL/MBLC size, moving beyond 318 kgf theoretical max requires migrating to a larger ISO 15552 profile cylinder. Choose this MBLC over the fixed-bumper MBL when your cycle speeds exceed the rubber bumper's absorption capacity or when moving heavier masses that would prematurely destroy a fixed stop. The adjustable needle decelerates the piston near the ends but is not a brake; if you need to hold position against air loss or exhaust, install an external rod lock or pilot-operated check valve. The U flat-end cover provides rigid rear mounting, contrasting with the CA pivot clevis which accommodates arcing loads. This SKU uses a PT tapered port thread and an M14x1.5 rod-end thread.

- ✓ 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 MBLC63X175U FAQ
This 63 mm bore cylinder uses a G1/4 port and an M14x1.5 rod-end thread. At 0.5 MPa it provides 1558 N push and 1457 N pull. At 0.7 MPa it provides 2181 N push. The theoretical maximum force is 318 kgf at 1.0 MPa.
A screw needle at both stroke ends traps a pocket of exhaust air to decelerate the piston smoothly before it hits the end cover. You tune the needle to match your specific load and speed, which cuts impact noise and vibration. It only decelerates near the ends and does not lock or hold the load if air pressure is lost.
