About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X80U
The AirTAC MBLC63X80U is a double-acting aluminum mini cylinder engineered for heavy small-footprint tasks, delivering 1558 N of push force at 0.5 MPa. Its 80 mm stroke is well-suited for high-force clamping or short ejection cycles. Unlike the base MBL, this variant features a screw-adjustable pneumatic cushion at both ends, allowing you to tune the end-of-stroke deceleration to match heavy loads and protect the end covers from impact.
This specific SKU includes a U flat-end back cover for rigid mounting and uses a default PT tapered port thread. Because it lacks the -S suffix, it has no internal magnet and cannot support CMSG, DMSG, or EMSG position sensors. The riveted rolling-packed aluminum barrel keeps the unit compact, while the Ø16 carbon-steel rod features 20 µm hard-chrome plating to resist wear. The heterogeneous two-way grease-retaining piston seal ensures consistent lubrication over millions of cycles.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X80U Is Used
Metal Stamping Ejection
Uses the 1558 N push force to eject dense stamped metal blanks from a press die, relying on the tuned air cushion to silently absorb the sudden stop at the 80 mm stroke end.
Pallet Diverting Arm
Swings heavy loaded pallets on a packaging line, where the adjustable end cushions prevent the rigid U back cover mounting from loosening under rapid directional changes.
PCB Pressing Fixture
Applies steady downward pressure on multilayer PCB lamination fixtures, utilizing the 1457 N pull force to cleanly retract the tooling without bouncing.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X80U the Right Cylinder?
Select this 63 mm bore when your application demands substantial force in a tight space; it provides 1558 N push and 1457 N pull at 0.5 MPa. If you need less force to prevent damaging delicate parts, step down to the 50 mm bore, which offers 981 N push at 0.5 MPa. If you require even more power, note that 63 mm is the largest standard MBL/MBLC size, offering a maximum theoretical 318 kgf at 1.0 MPa. Choose this MBLC over the fixed-bumper MBL when moving heavier masses at higher speeds where a rubber bumper would degrade too quickly. Remember that the adjustable air cushion only decelerates the piston near the stroke ends; it is not a brake and will not hold the load if air pressure is lost. For exact replacement, match the 63 mm bore, 80 mm stroke, G1/4 port, PT thread, and U flat-end back 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 MBLC63X80U 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 when operated at the 1.0 MPa pressure limit.
No, this specific SKU lacks the built-in magnet (denoted by an -S suffix), meaning it cannot accommodate AirTAC CMSG, DMSG, or EMSG sensor switches. If you require electronic or reed position detection, you must select the MBLC63X80S variant instead.
