About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X80SU
The AirTAC MBLC50X80SU is a double-acting aluminum mini cylinder engineered for compact setups requiring substantial thrust, delivering 981 N push and 881 N pull at 0.5 MPa. Driven by air through its G1/4 port, it uses a Ø16 carbon-steel rod with a 20 um hard-chrome plating to resist wear. The 80 mm stroke is optimal for short, high-force transitions in confined machinery spaces.
Unlike the base MBL which relies on a fixed rubber bumper, this MBLC variant features a screw-adjustable pneumatic cushion at both ends. You tune the needle to smoothly decelerate the piston near each stroke limit, absorbing kinetic energy to protect the end covers on faster or heavier moves. The riveted rolling-packed aluminum barrel keeps the body light and tight, while the U flat-end back cover provides a rigid rear mount for straight-line thrust.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X80SU Is Used
Injection Mold Ejection
Provides the 981 N push force needed to eject dense plastic parts from molds within an 80 mm travel, using the tunable cushion to prevent harsh end-of-stroke impacts on fast cycle times.
Bottle Diverting Arm
Drives a heavy stainless steel diverting arm on a packaging line, where the adjustable air cushion smoothly slows the 50 mm bore rod to cut vibration and protect the U flat-end cover.
PCB Pressing Station
Applies precise downward pressure on electronic assemblies, using the -S magnet with a DMSG solid-state sensor to confirm the 80 mm stroke endpoint for process validation.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X80SU the Right Cylinder?
Choose this 50 mm bore when your application requires around 981 N of thrust at 0.5 MPa. If you need less force, the 40 mm bore offers 628 N push; if you need more, the 63 mm bore provides 1558 N. The adjustable air cushion justifies choosing MBLC over the standard MBL when your cycle speeds are high or the moved mass is heavy enough that a fixed bumper would fail prematurely.
For replacement matching, confirm the 50 mm bore, 80 mm stroke, G1/4 port, PT thread, U flat-end back cover, and the built-in magnet. The -S magnet enables position detection via AirTAC CMSG (reed), DMSG, or EMSG (electronic) switches. Note that the air cushion only decelerates the piston near the ends; it does not lock the rod. If you need position holding without live air, install an external rod lock or pilot-operated check valve.

- ✓ 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 MBLC50X80SU FAQ
At 0.5 MPa, this 50 mm bore cylinder outputs 981 N of push force and 881 N of pull force. At 0.7 MPa, push increases to 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa. It operates at speeds between 30 and 800 mm/s.
The MBLC50X80SU uses a screw-tunable pneumatic cushion at both ends. You adjust the needle to trap exhaust air, decelerating the piston smoothly near the stroke limits. This protects the end covers from impact on fast moves, unlike a fixed rubber bumper, but it does not lock the load.
