About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X500U
The AirTAC MBLC63X500U is a double-acting aluminum mini cylinder engineered for heavy-duty linear motion across a 500 mm stroke. It generates 1558 N of push force and 1457 N of pull force at 0.5 MPa, peaking at a theoretical 318 kgf at 1.0 MPa. The U code denotes a rigid flat-end back cover for direct mounting. Because this SKU lacks the -S magnet code, it cannot host a CMSG, DMSG, or EMSG position sensor.
Unlike the base MBL bumper design, the MBLC features a screw-adjustable pneumatic cushion at both ends. This is essential for a 500 mm move, allowing you to tune the needle to smoothly decelerate a heavy 63 mm piston, preventing end-cover shock. The riveted rolling-packed aluminum barrel keeps the body compact, while the Ø16 carbon-steel rod features 20 µm hard-chrome plating to resist wear and extend seal life.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X500U Is Used
CNC Pallet Shuttle
Drives heavy machining pallets along a 500 mm track; the tunable air cushion absorbs the 318 kgf peak kinetic energy, preventing impact damage to the precision tool changer.
Pallet Transfer Reject
Pushes rejected automotive subassemblies off a main conveyor line, utilizing the 1558 N push force to overcome the inertia of heavy steel fixtures.
Warehouse Storage Crane
Actuates a vertical lift mechanism for heavy tote boxes, relying on the rigid U flat-end cover to withstand the high push and pull forces during 500 mm elevation cycles.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X500U the Right Cylinder?
At 0.5 MPa, this 63 mm bore yields 1558 N push force. If your load is lighter, stepping down to the 50 mm bore reduces bulk and yields 981 N push. If you need more power, 63 mm is the largest standard mini size available. For a 500 mm stroke, the 8-800 mm/s speed range and small Ø16 rod create a high risk of side-load buckling; you must use an external guide rail, an SDB pivot bracket, or switch to an MBLD double-rod cylinder to prevent binding. Remember that the adjustable cushion only decelerates the piston near the stroke ends—it is not a brake and will not hold the load if air pressure drops. Replacement parts require a 63 mm bore, 500 mm stroke, G1/4 port, PT thread, and U flat-end cover.
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 MBLC63X500U FAQ
At 0.5 MPa, this 63 mm cylinder provides 1558 N push and 1457 N pull. At 0.7 MPa, it delivers 2181 N push. The maximum theoretical force is 318 kgf at 1.0 MPa operating pressure.
The MBLC63X500U uses a screw-adjustable pneumatic cushion at both ends. You tune the needle to match your load and speed, trapping a pocket of air to decelerate the piston smoothly before the end cover. This prevents harsh impact on long 500 mm strokes. It is a deceleration device, not a locking brake.
