About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X50CA
The AirTAC MBLC63X50CA is a double-acting aluminum mini cylinder featuring a 63 mm bore and 50 mm stroke, delivering a 1558 N push force at 0.5 MPa. It uses a G1/4 port and a Ø16 hard-chrome carbon-steel rod with an M14x1.5 end thread. The CA pivot clevis back cover allows the body to swing on a pin, accommodating arcing and angular loads that would bind a rigid mount.
Unlike the base MBL fixed-bumper series, this MBLC variant incorporates a screw-adjustable pneumatic air cushion at both ends. Tuning the needle decelerates the piston smoothly near stroke ends, cutting impact shock on fast or heavy moves. The riveted rolling-packed aluminum barrel keeps the body compact for tight spaces, while the heterogeneous two-way grease-retaining piston seal maintains lubrication. Note that this specific SKU lacks a built-in magnet, so it cannot support CMSG, DMSG, or EMSG position sensors.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X50CA Is Used
Packaging Arm Pivot
Drives a sealing arm on a continuous flow wrapper, using the CA clevis to swing freely and the air cushion to absorb the 1558 N push at high cycle rates.
Sorter Diverter
Kicks heavy totes on a logistics conveyor, where the 50 mm stroke and tunable end-cushioning prevent end-cover damage during rapid extension.
Pallet Transfer Stop
Acts as a high-force pop-up stop for loaded pallets, relying on the pivot mount to handle angular misalignment as the pallet pushes past.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X50CA the Right Cylinder?
Stepping down from this 63 mm bore (1558 N push @0.5 MPa), the 50 mm bore yields 981 N and uses the same G1/4 port. Stepping up is not possible as 63 mm is the largest standard mini size in this family. Choose this MBLC over the base MBL when moving heavier masses at high cycling speeds where a fixed rubber bumper would wear out too quickly. Keep in mind the air cushion only decelerates near the ends; it is not a lock, so the rod will drift if air is lost. For replacement, match the 63 mm bore, 50 mm stroke, PT thread, CA pivot cover, and no magnet.
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 MBLC63X50CA FAQ
At 0.5 MPa, the push force is 1558 N and the pull force is 1457 N. At 0.7 MPa, the push is 2181 N and the pull is 2040 N. The maximum theoretical force is 318 kgf at 1.0 MPa.
The MBLC uses a screw-adjustable air cushion at both ends instead of a fixed rubber bumper. You tune the needle to decelerate the piston smoothly near the stroke ends, which is critical for protecting the end covers on fast moves or heavy 63 mm bore loads. It decelerates only; it does not lock the rod.
