About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X75U
The AirTAC MBLC63X75U is a double-acting aluminum mini cylinder engineered with a screw-adjustable pneumatic cushion at both stroke ends. Generating 1558 N of push force at 0.5 MPa (2181 N at 0.7 MPa) over a 75 mm stroke, it is built to move heavier masses rapidly while protecting the end covers from impact. The U suffix denotes a rigid flat-end back cover for straightforward inline mounting.
This model relies on a riveted rolling-packed aluminum barrel to keep the body compact and lightweight, rather than a bulky rebuildable tie-rod assembly. Inside, a heterogeneous two-way grease-retaining piston seal works alongside a 20 µm hard-chrome plated carbon-steel rod to maintain consistent friction and extend seal life. Because this specific SKU lacks the -S magnet code, it cannot host a CMSG, DMSG, or EMSG position sensor.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X75U Is Used
Injection Mold Ejection
Provides a robust 1558 N push at 0.5 MPa to eject dense plastic parts from mold cavities, using the adjustable cushion to soften the 75 mm stroke stop and protect the mold face.
Pallet Diverting
Drives heavy-duty pallet routing gates where the 63 mm bore handles the mass, while the needle-tuned cushion prevents jarring shocks that could destabilize the conveyed goods.
Carton Flap Folding
Powers heavy corrugated carton flap tucking arms in continuous packaging lines, relying on the riveted aluminum body to survive high-frequency impacts in tight machine frames.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X75U the Right Cylinder?
This 63 mm bore yields 1558 N push and 1457 N pull at 0.5 MPa. If your payload requires less force, the 50 mm neighbour outputs 981 N push and 881 N pull, making it a lighter, more compact alternative. Since 63 mm is the largest standard size in this mini-cylinder family, stepping up beyond 318 kgf at 1.0 MPa requires migrating to a larger ISO 15552 profile body. Choose this MBLC variant over the fixed-bumper MBL base type when your cycle speeds are high enough that a rubber pad cannot adequately absorb the kinetic energy. Keep in mind that the adjustable air cushion only decelerates the piston near the stroke ends; it is not a braking lock, so the rod will drift if air pressure is lost or the valve centers. For a direct replacement, match the 63 mm bore, 75 mm stroke, G1/4 port, PT thread, U flat-end cover, and no magnet.
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 MBLC63X75U FAQ
The 63 mm bore uses a G1/4 port and a Ø16 mm rod with an M14x1.5 rod-end thread. At 0.5 MPa it provides 1558 N push and 1457 N pull force. At 0.7 MPa the push increases to 2181 N, with a maximum theoretical push of 318 kgf at 1.0 MPa.
No. This specific SKU lacks the -S code, meaning it has no built-in magnet and cannot host CMSG reed or DMSG/EMSG electronic sensor switches. You would need the MBLC63X75SU variant for position detection. The needle-adjustable air cushion at both ends functions to smoothly decelerate the load, not to hold position.
