About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X15U
The AirTAC MBLC63X15U is a double-acting aluminum mini cylinder engineered for high-force, short-trroke tasks. It generates 1558 N of push force at 0.5 MPa, utilizing a 63 mm bore and a 15 mm stroke to execute rapid, heavy-duty work within a compact footprint. The U designation indicates a rigid flat-end back cover for straightforward rigid mounting.
Unlike the standard bumper-equipped MBL, this variant features a screw-adjustable pneumatic air cushion at both stroke ends. By tuning the needle valves, you control the end-of-stroke deceleration to match the load and velocity, significantly reducing impact shock and vibration. The riveted rolling-packed aluminum barrel keeps the body light, while the Ø16 mm carbon-steel rod features 20 µm hard-chrome plating to resist wear. Note that this specific SKU lacks a built-in magnet and cannot support CMSG, DMSG, or EMSG position sensors.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X15U Is Used
Short-Stroke Staking
Ideal for driving a staking punch into sheet metal, where the 1558 N force at 0.5 MPa deforms the material in a tight 15 mm travel window.
Heavy Part Ejection
Provides a rapid, high-thrust burst to eject dense machined steel components from a conveyor bed before the next cycle begins.
PCB Pressing
Delivers controlled downward pressure for seating thick connectors into PCBs, utilizing the tuned air cushion to prevent impact damage.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X15U the Right Cylinder?
Selecting the MBLC63X15U is optimal when your application requires maximum thrust in a minimal stroke. If you need less force, stepping down to the 50 mm bore yields 981 N of push at 0.5 MPa; conversely, the 63 mm bore is the largest available in this series, delivering 1558 N at 0.5 MPa and a maximum theoretical 318 kgf at 1.0 MPa. The adjustable air cushion is specifically beneficial here: even at 15 mm, moving a heavy mass at high speed generates significant kinetic energy that a fixed rubber bumper cannot adequately absorb.
Because this SKU has a U flat-end back cover, it mounts rigidly for straight-line thrust. The PT tapered port threads seal directly on the G1/4 port. Remember that the air cushion only decelerates the piston near the end caps; it is not a mechanical lock. If the air supply is dropped or the valve centers, the rod will drift, requiring an external pilot-operated check valve for position holding.
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 MBLC63X15U FAQ
This 63 mm bore cylinder has a G1/4 port and an M14x1.5 rod-end thread. At 0.5 MPa it 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.
No, this specific SKU does not have an S in the model code, meaning it lacks a built-in magnet. You must select an MBLC63X15S variant to use AirTAC CMSG reed or DMSG/EMSG electronic solid-state sensor switches for rod position detection.
