About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X450CA
The AirTAC MBLC63X450CA is a double-acting single-rod aluminum mini cylinder engineered for heavy-duty linear motion. 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. Driven by a Ø16 mm carbon-steel rod with 20 um hard-chrome plating, this 450 mm stroke unit is built for substantial travel distances within a compact riveted rolling-packed barrel.
Unlike the base MBL series which relies on a fixed rubber bumper, this MBLC variant features a screw-adjustable pneumatic air cushion at both ends. Tuning the cushion needle lets you smoothly decelerate the piston near stroke extremes, effectively absorbing kinetic energy from heavy fast-moving loads to protect the end covers. The CA back cover provides a pivot clevis that swings on a pin, making it ideal for arcing or angular load paths. Note that this specific SKU lacks a built-in magnet and cannot support a CMSG, DMSG, or EMSG position sensor.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X450CA Is Used
Stamping Press Feed
Pushes heavy coil stock into a mechanical press over 450 mm, relying on the 1558 N push force and tuned end-cushions to prevent slamming the clevis bracket at high cycle rates.
Pallet Transfer Indexer
Indexes loaded pallets along a chain conveyor, using the CA pivot clevis to accommodate the slight vertical arc as the 63 mm bore moves the mass forward.
Carton Case Erector
Folds and pushes heavy corrugated blanks at 0.7 MPa, where the 2181 N force and adjustable pneumatic cushioning absorb the kinetic energy of the 450 mm rapid stroke.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X450CA the Right Cylinder?
As the largest standard bore in this mini-cylinder family, the 63 mm body leaves no room to step up in size. If your application requires less force, stepping down to the 50 mm bore yields 981 N push at 0.5 MPa. Choose this MBLC over the fixed-bumper MBL when your mechanism cycles rapidly or moves a heavy mass that would destroy a standard rubber bumper. Remember that the adjustable air cushion only decelerates the piston near the ends; it is not a brake and will not hold the load if air pressure drops. For replacement matching, confirm the 63 mm bore, 450 mm stroke, G1/4 port, PT thread, CA pivot cover, and non-magnet configuration. At 450 mm of stroke, the 16 mm rod is highly susceptible to side-loading and bending; you must use an external guide rail, rely on the CA pivot to absorb angularity, or switch to an MBLD double-rod cylinder to prevent premature seal failure.
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 MBLC63X450CA FAQ
At 0.5 MPa, this 63 mm bore cylinder provides 1558 N of push force and 1457 N of pull force. At 0.7 MPa, the push force increases to 2181 N. The maximum theoretical force is 318 kgf at 1.0 MPa. It operates at speeds between 30 and 800 mm/s.
The MBLC63X450CA uses a screw-adjustable pneumatic cushion at both ends instead of a fixed rubber bumper. By turning the needle valve, you trap a pocket of exhaust air to smoothly decelerate the piston near the stroke extremes. This is critical for heavy loads at 450 mm stroke, though it only decelerates and does not lock the rod in place.
