About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X450U
The AirTAC MBLC63X450U is a double-acting mini cylinder featuring a 63 mm bore and 450 mm stroke. It delivers 1558 N of push force and 1457 N of pull force at 0.5 MPa. A built-in adjustable air cushion at both ends allows you to screw-tune the end-of-stroke deceleration, absorbing kinetic energy smoothly to prevent end-cover impact on heavy 450 mm moves. The U suffix denotes a rigid flat-end back cover.
This unit uses a G1/4 port and a 16 mm hard-chrome carbon-steel rod with an M14x1.5 end thread. Its riveted rolling-packed aluminum barrel keeps the body compact while retaining pressure. Because this SKU lacks the S magnet code, it cannot host a CMSG, DMSG, or EMSG position sensor.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X450U Is Used
Pallet Transfer Line
Pushes heavy loaded pallets between roller conveyors, using the 1558 N force and tuned air cushions to halt the 450 mm travel without slamming the frame.
Press Feed Ejection
Ejects stamped metal parts from a hydraulic press bed, relying on the 63 mm bore power and smooth end-cushioning to protect the tooling on fast retraction.
Multi-Tier Stacking
Raises cardboard cartons to upper tier packaging chutes, where the 450 mm stroke reaches high bays while the cushions prevent jarring drops at the top.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X450U the Right Cylinder?
At 0.5 MPa, this 63 mm bore yields 1558 N push force. If your payload is lighter, stepping down to the 50 mm bore reduces the push force to 981 N while saving space. If you need more power, there is no larger standard MBL size, so you would transition to an ISO 15552 profile cylinder. Choose this MBLC over the base MBL when moving substantial mass at high speeds, as the fixed rubber bumper on the MBL cannot absorb the kinetic energy safely.
A 450 mm stroke generates significant leverage on the 16 mm rod, making it highly susceptible to side-load bending. To manage this, mount the load through an external guide rail, switch to a CA or SDB pivot bracket for arcing loads, or use an MBLD double-rod cylinder to prevent twisting. This U-type flat-end rear cover provides rigid straight-line mounting. It uses PT tapered thread ports.

- ✓ 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 MBLC63X450U FAQ
At 0.5 MPa it provides 1558 N push and 1457 N pull. At 0.7 MPa it yields 2181 N push, with a theoretical maximum of 318 kgf at 1.0 MPa. It features a 63 mm bore, a 16 mm rod with an M14x1.5 end thread, and a G1/4 port.
A screw-tunable needle at both ends traps a pocket of exhaust air to decelerate the piston smoothly before it hits the end cover. You dial the needle to match your load and speed, which is critical for a 450 mm stroke. This cushion only slows the rod near the ends; it does not lock or hold the load if air pressure drops.
