About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X450SCA
The AirTAC MBLC63X450SCA is a double-acting, single-rod aluminum mini cylinder engineered for demanding actuation. It generates 1558 N of push force and 1457 N of pull force at 0.5 MPa, scaling up to 2181 N push at 0.7 MPa. The 450 mm stroke is ideal for long-travel material transfer or robust positioning tasks. Unlike the base MBL series, this variant incorporates a screw-adjustable pneumatic air cushion at both stroke ends, allowing you to precisely tune the end-of-travel deceleration to protect the end covers on heavy, fast moves.
This model features a built-in magnet (-S) for compatibility with AirTAC CMSG, DMSG, and EMSG sensor switches to track rod position. It uses a CA pivot (clevis) back cover that swings on a pin to accommodate arcing loads, which is critical for a 450 mm stroke. The riveted rolling-packed aluminum barrel keeps the body compact, while the Ø16 mm carbon-steel rod features 20 µm hard-chrome plating paired with a heterogeneous two-way grease-retaining piston seal for extended service life.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X450SCA Is Used
Pallet Transfer Line
Drives a 450 mm stroke pusher on an automated pallet conveyor, using the adjustable cushion to smoothly stop the 1558 N push force without jarring the end cover.
Stamping Press Feed
Feeds heavy blanks into a mechanical stamping press, where the CA pivot clevis absorbs angular rod stress during the long arcing motion.
Automated Warehousing
Actuates a heavy goods diverter arm in a high-throughput distribution hub, relying on the -S magnet and DMSG sensor to confirm stroke end position.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X450SCA the Right Cylinder?
At 63 mm bore, this cylinder provides 1558 N push at 0.5 MPa. If your application requires less force, stepping down to the 50 mm bore yields 981 N push. If you need maximum thrust, this 63 mm bore is the largest available in the series, delivering up to 318 kgf at 1.0 MPa. Choose the MBLC over the fixed-bumper MBL when your cycle speeds are high or the moved mass is substantial, as the tunable needle decelerates the piston smoothly rather than relying on a rubber impact. Note that the air cushion only slows the piston near the ends; it is not a brake and will not hold the load if air pressure is lost.
For replacement, match the 63 mm bore, 450 mm stroke, G1/4 port, PT thread, CA pivot back cover, and the -S magnet. Because the 450 mm stroke is long, the small Ø16 mm rod has low side-load tolerance. You must use an external guide rail, leverage the CA pivot's self-aligning capability, or switch to an MBLD double-rod cylinder to prevent rod bending and premature seal wear.
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 MBLC63X450SCA FAQ
This 63 mm bore cylinder provides 1558 N push and 1457 N pull at 0.5 MPa. At 0.7 MPa, it delivers 2181 N push and 2040 N pull. The maximum theoretical force is 318 kgf at 1.0 MPa.
The MBLC63X450SCA uses a screw-tunable pneumatic needle at both ends to trap and meter exhaust air, decelerating the piston smoothly before impact. You tune the needle to match your load and speed, which is essential for protecting the end covers on long, heavy 450 mm strokes. It only decelerates near the ends and does not lock the load.
