About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X175SU
The AirTAC MBLC63X175SU is a double-acting aluminum mini cylinder engineered with a screw-adjustable pneumatic cushion at both stroke ends. Delivering a 1558 N push force at 0.5 MPa (2181 N at 0.7 MPa), this 63 mm bore, 175 mm stroke unit smoothly decelerates heavy fast-moving loads to prevent end-cover impact. The built-in magnet (-S) supports CMSG, DMSG, and EMSG sensor switches for precise position detection.
Unlike fixed-bumper designs, the needle-valve cushion lets you tune end-of-stroke deceleration for high-frequency cycling. The riveted rolling-packed aluminum barrel keeps the body light and compact, while the 20 µm hard-chrome plated carbon-steel rod resists wear. The heterogeneous two-way grease-retaining piston seal maintains lubrication for a long service life.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X175SU Is Used
Injection Mold Ejection
Provides 1558 N of thrust at 0.5 MPa to eject heavy plastic parts from injection molds, using the adjustable cushion to soften the 175 mm return stop.
Pallet Diverting
Pushes loaded pallets at sorting junctions, relying on the tunable air cushion to decelerate the 63 mm piston and minimize impact vibration.
Heavy Carton Stacking
Lifts dense packaging in tight palletizer cells, where the compact riveted aluminum barrel saves space without sacrificing the 318 kgf maximum theoretical force.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X175SU the Right Cylinder?
At 0.5 MPa, this 63 mm bore generates 1558 N push and 1457 N pull. If you need less force, the 50 mm bore offers 981 N push; if you require more, 63 mm is the largest standard MBL size. Choose this MBLC over the base MBL when your cycle speed or moving mass exceeds what a fixed rubber bumper can absorb. The U suffix denotes a rigid flat-end back cover for straight-line thrust. Note that the air cushion only decelerates near the ends—it is not a lock. The cylinder will drift if air is lost; use an external rod lock for position holding. Porting is G1/4 with an M14x1.5 rod thread.
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 MBLC63X175SU FAQ
At 0.5 MPa, it pushes with 1558 N and pulls with 1457 N. At 0.7 MPa, push increases to 2181 N. The maximum theoretical force is 318 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
The cushion is a screw-tunable needle valve at both ends that traps exhaust air to decelerate the piston smoothly, reducing impact on fast or heavy moves. The -S suffix means the cylinder has a built-in magnet for CMSG reed or DMSG/EMSG electronic sensor switches.
