About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X80U
The AirTAC MBLC50X80U is a double-acting aluminum mini cylinder engineered for compact spaces requiring substantial thrust. It generates 981 N of push force and 881 N of pull force at 0.5 MPa, moving an 80 mm stroke via a Ø16 mm carbon-steel rod with 20 µm hard-chrome plating. The U designation indicates a rigid flat-end back cover, providing a straightforward, fixed mounting interface for straightforward linear push applications.
Unlike the base MBL series which relies on a fixed rubber bumper, this MBLC variant features a screw-adjustable pneumatic air cushion at both stroke ends. You tune the cushion needle to match your load and speed, smoothly decelerating the piston to protect the end covers and reduce vibration on high-impact moves. The body utilizes a riveted rolling-packed aluminum barrel for lightweight durability, and since this specific SKU lacks the -S magnet code, it cannot accept a CMSG, DMSG, or EMSG position sensor switch.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X80U Is Used
Injection Mold Ejection
Provides 981 N of push force to eject plastic parts from small injection molds, using the tunable air cushion to prevent harsh impacts during fast 80 mm ejection strokes.
Carton Flap Folding
Drives a folding mechanism on packaging lines at speeds up to 800 mm/s, where the adjustable cushion ensures the flap is tucked smoothly without crushing the cardboard.
Pallet Stopper Gate
Acts as a compact 80 mm stroke stop gate on roller conveyors, absorbing the momentum of incoming product loads with its end-of-stroke cushioning rather than a rigid crash.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X80U the Right Cylinder?
When sizing this 50 mm bore, stepping down to the 40 mm bore drops the push force to 628 N at 0.5 MPa, while stepping up to the 63 mm bore increases it to 1558 N. Choose this MBLC over the fixed-bumper MBL when your cycle speeds are high or the moved mass is heavy enough that impact at the 80 mm stroke end would damage a standard cylinder. Note that the adjustable air cushion only decelerates the piston near the ends; it is not a brake. If you need to hold position during air loss or valve centering, this cylinder will drift, requiring an external rod lock or pilot-operated check valve. Replacement requires matching the 50 mm bore, 80 mm stroke, G1/4 port, PT thread, U flat-end back 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 MBLC50X80U FAQ
At 0.5 MPa, this 50 mm bore cylinder provides 981 N of push force and 881 N of pull force. At 0.7 MPa, the push force is 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa.
A screw-tunable needle at both ends regulates exhaust flow to decelerate the piston smoothly near the stroke ends. You adjust it to match your specific load and speed, which cuts impact noise and end-cover wear compared to a fixed rubber bumper, but it does not lock the rod in place.
