About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X50U
The AirTAC MBLC63X50U is a double-acting aluminum mini cylinder engineered for compact spaces demanding high force. It generates 1558 N of push force and 1457 N of pull force at 0.5 MPa. Driven by air through its G1/4 port, the 50 mm stroke suits short, heavy part transfers. The U designation specifies a rigid flat-end back cover for direct straight-line mounting.
This model features a screw-adjustable air cushion at both ends to decelerate the piston smoothly near stroke limits, reducing impact and vibration on rapid moves. Unlike a fixed rubber bumper, the cushion needle is tunable to match your load and speed. The riveted rolling-packed aluminum barrel keeps the body light and compact. A 20 µm hard-chrome plating on the carbon-steel rod pairs with a heterogeneous two-way grease-retaining piston seal for low-friction, long-life operation.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X50U Is Used
Injection Mold Ejection
Provides the 1558 N push force needed to eject dense plastic parts from a mold, with the 50 mm stroke and adjustable cushion preventing hard slamming at high cycle rates.
Pallet Diverter
Shifts heavy loaded pallets on a packaging conveyor line. The compact riveted barrel fits within tight machine frames while the G1/4 port supplies the high air volume required.
Press Die Stamping
Executes short 50 mm stamping actions on thin metal sheets in an electronics assembly line, utilizing the smooth end-of-stroke deceleration to protect the die and lower noise.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X50U the Right Cylinder?
Choose this 63 mm bore when you need 1558 N of thrust at 0.5 MPa. If your load is lighter, step down to the 50 mm bore which yields 981 N of push force. If you require even more power, 63 mm is the largest available bore in this series, delivering a maximum theoretical output of 318 kgf at 1.0 MPa. The U flat-end rear cover provides rigid mounting; select a CA pivot cover instead if your mechanism requires arcing movement. Because this SKU lacks the -S magnet code, it cannot accept a CMSG, DMSG, or EMSG position sensor. For position feedback, you would need an -S variant. Note that an air cushion only decelerates the rod near the ends; it does not hold position if air pressure drops. For dead-load holding without live air, install an external rod lock.
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 MBLC63X50U 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 is 2181 N and the pull force is 2040 N. The maximum theoretical force is 318 kgf at 1.0 MPa. The operating speed range is 30-800 mm/s.
No, because this specific SKU lacks the -S suffix, it does not have a built-in magnet and cannot host a CMSG, DMSG, or EMSG sensor switch. You must select an MBLC63X50S model to enable electronic or reed switch position detection.
