About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X75SU
The AirTAC MBLC63X75SU is a double-acting aluminum mini cylinder engineered for heavy-duty compact automation, delivering a robust 1558 N push force at 0.5 MPa. The 75 mm stroke provides rapid, high-impact extension and retraction cycles. Unlike the base MBL series, this variant features a screw-adjustable pneumatic air cushion at both stroke ends. This allows you to precisely tune the end-of-stroke deceleration to match heavy loads, significantly dampening impact shock, reducing noise, and protecting the end covers during high-frequency operation.
Built with a riveted rolling-packed aluminum barrel for a lightweight yet rigid frame, the unit integrates a heterogeneous two-way grease-retaining piston seal and a 20 µm hard-chrome plated carbon-steel rod for low-friction longevity. The built-in magnet (-S) supports CMSG, DMSG, and EMSG sensor switches for exact position detection, while the U flat-end back cover ensures rigid, straight-line mounting. Fluid is filtered air, operating pressure spans 0.15-1.0 MPa, and the standard speed range reaches 30-800 mm/s.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X75SU Is Used
Injection Mold Ejection
Provides the 1558 N push force needed to eject dense plastic parts from mold cavities, using the adjustable cushion to soften the 75 mm stroke termination and protect tooling.
Pallet Diverting Arm
Drives a heavy routing arm to push loaded pallets onto secondary packaging lines, relying on the tunable air cushion to absorb the mass of the shifting load without slamming.
PCB Stacking Press
Utilizes the integrated magnet with a DMSG solid-state sensor to confirm stack height, while the 63 mm bore supplies consistent downward pressure for compacting delicate assemblies.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X75SU the Right Cylinder?
Select this 63 mm bore when your application requires substantial thrust—1558 N push and 1457 N pull at 0.5 MPa. If you need less force, stepping down to the 50 mm bore yields 981 N push, whereas moving up is not possible as 63 mm is the largest standard MBL/MBLC size. Choose the MBLC over the fixed-bumper MBL when moving heavier masses at high velocities, as the tunable cushion prevents destructive end-cap collisions. Remember that the air cushion only decelerates near the ends; it is not a brake. A plain double-acting cylinder does not hold position if air is lost or the valve centers, so fit an external rod lock or pilot-operated check for fail-safe load holding. This exact replacement match requires a 63 mm bore, 75 mm stroke, G1/4 port, PT thread, U flat-end back cover, and the -S magnet.

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 MBLC63X75SU 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, push increases to 2181 N. The maximum theoretical force is 318 kgf at 1.0 MPa. It uses a G1/4 port, a Ø16 mm rod, and an M14x1.5 rod-end thread.
The cushion is a screw-tunable needle valve at both ends that traps a pocket of exhaust air to decelerate the piston before it hits the end cover. You adjust it to match your specific load and speed, which eliminates the harsh impact and vibration that a fixed rubber bumper cannot absorb on fast, heavy cycles.
