About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X125SCA
The AirTAC MBLC63X125SCA is a double-acting aluminum mini cylinder engineered for heavy-duty compact automation, delivering 1558 N of push force at 0.5 MPa. Its 125 mm stroke is optimized for mid-range travel in tight spaces. Unlike the base MBL which relies on a fixed rubber bumper, this MBLC variant features a screw-adjustable pneumatic cushion at both ends. This allows you to precisely tune the end-of-stroke deceleration, absorbing the kinetic energy of fast-moving 318 kgf loads to prevent end-cover impact and vibration.
The CA pivot back cover swings on a pin to accommodate arcing loads, making it superior to a rigid flat-end mount for angular movements. A built-in magnet (-S) enables position detection with AirTAC CMSG, DMSG, or EMSG sensor switches. The riveted rolling-packed aluminum barrel keeps the body light, while the Ø16 carbon-steel rod features 20 µm hard-chrome plating to resist wear. A heterogeneous two-way grease-retaining piston seal ensures consistent friction and longevity across its 30-800 mm/s operating speed range.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X125SCA Is Used
Injection Mold Ejection
Provides 1558 N of force at 0.5 MPa to eject heavy plastic parts from molds. The adjustable air cushion ensures the 125 mm stroke retracts smoothly without slamming the back cover during high-speed cycling.
Pallet Diverting Arms
The CA pivot clevis allows the cylinder to swing a diverting arm smoothly across a conveyor belt. The tunable cushion absorbs the kinetic energy of redirecting heavy pallets, reducing mechanical shock.
PCB Pressing Stations
Uses the -S magnet with DMSG electronic sensors to confirm exact pressing positions on circuit board assemblies. The 63 mm bore supplies the high downward force required for secure component seating.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X125SCA the Right Cylinder?
Select this 63 mm bore when your application requires the highest thrust in the MBL/MBLC family, pushing 1558 N at 0.5 MPa. If you need less force, step down to the 50 mm bore which provides 981 N of push force. As this is the largest standard mini round bore available, there is no larger neighbor in this series. The adjustable air cushion is essential here; choose the base MBL only if your cycle is slow and light enough that a fixed rubber bumper suffices. Remember, the pneumatic cushion decelerates the piston near the ends but does not lock the rod—if air pressure drops, the cylinder drifts, so fit an external rod lock for fail-safe holding.
This SKU includes the CA pivot back cover for angular load articulation and a built-in magnet (-S) for CMSG/DMSG/EMSG sensors. The port is G1/4 with PT thread, and the rod end uses an M14x1.5 thread. Because the stroke is 125 mm, side-load stress on the 16 mm rod is manageable, but always verify alignment to avoid premature seal wear.

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 MBLC63X125SCA FAQ
At 0.5 MPa, the push force is 1558 N and the pull force is 1457 N. At 0.7 MPa, the push force increases to 2181 N. The maximum theoretical force is 318 kgf at 1.0 MPa.
The cushion is a screw-tunable pneumatic needle at both ends of the cylinder. It traps exhaust air at the end of the stroke to decelerate the piston smoothly. You adjust it to match the load and speed, which prevents end-cover impact. It is strictly a deceleration device, not a brake or load lock.
