About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X350U
The AirTAC MBLC63X350U is a double-acting aluminum mini cylinder engineered for substantial actuation tasks, delivering 1558 N of push force and 1457 N of pull force at 0.5 MPa. Its 350 mm stroke is well-suited for traversing larger machine envelopes, such as pushing heavy pallets or routing wide film webs. A defining trait of this MBLC variant is the screw-adjustable pneumatic cushion at both ends, which decelerates the piston smoothly near stroke limits to minimize end-cover impact and vibration during high-speed cycles.
Unlike the base MBL series which relies on a fixed rubber bumper, this model allows you to tune the exhaust needle to match your specific load and velocity. The cylinder body utilizes a riveted rolling-packed aluminum barrel for a compact, lightweight profile rather than a bulky rebuildable tie-rod assembly. It features a carbon-steel piston rod with a 20 µm hard-chrome plating paired with a heterogeneous two-way grease-retaining piston seal for long-lasting lubrication. This specific U back cover configuration provides a rigid flat-end mounting surface for straightforward inline installation.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X350U Is Used
Pallet Diversion
Leverages the 1558 N push force at 0.5 MPa to redirect heavy loaded pallets on a high-speed packaging line, relying on the adjustable air cushion to softly stop the 350 mm stroke and prevent load spillage.
Injection Mold Ejection
Drives an ejection arm out of a large molding press, using the 350 mm stroke to clear the wide machine platen while the cushion needle is tuned to decelerate the heavy mold tooling smoothly.
Carton Push-Off
Pushes heavy corrugated cartons from an accumulation zone in a logistics hub, where the 63 mm bore provides the necessary 318 kgf maximum force to overcome sliding friction over a long 350 mm travel distance.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X350U the Right Cylinder?
Selecting this 63 mm bore makes sense when your application requires substantial thrust—such as 1558 N push at 0.5 MPa or a maximum of 318 kgf at 1.0 MPa. If you need less force and a smaller footprint, stepping down to the 50 mm bore yields 981 N of push force at 0.5 MPa. Since 63 mm is the largest standard size in this mini-cylinder family, moving up in force would require migrating to a different ISO 15552 cylinder platform. Choose the MBLC over the fixed-bumper MBL when your cycle speeds are high or the moved mass is heavy enough that impact deceleration is necessary.
Because this model features a 350 mm stroke, the Ø16 mm rod is highly susceptible to bending under lateral loads or side forces. To prevent premature seal failure and rod damage, you must support the load with an external linear guide, utilize a pivot mounting bracket like SDB, or switch to a double-rod MBLCD configuration. This specific SKU lacks the -S magnet option, meaning it cannot support CMSG, DMSG, or EMSG position sensors without changing the model code. The U flat-end back cover provides a rigid rear mounting face, and the ports use the default PT thread form.
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 MBLC63X350U FAQ
This 63 mm bore cylinder uses a G1/4 port and an M14x1.5 rod-end thread. At 0.5 MPa it provides 1558 N of push force and 1457 N of pull force. At 0.7 MPa the push increases to 2181 N, and it reaches a maximum theoretical force of 318 kgf at 1.0 MPa.
This specific SKU lacks the -S suffix, so it has no built-in magnet and cannot accept CMSG, DMSG, or EMSG sensor switches. The adjustable air cushion at both ends is a screw-tunable pneumatic valve that restricts exhaust flow near the stroke ends to decelerate the piston; it is designed to smooth out fast, heavy moves and is not a mechanical locking brake.
