About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X80SU
The AirTAC MBLC63X80SU is a double-acting, 63 mm bore mini cylinder with an 80 mm stroke, engineered to deliver 1558 N of push force at 0.5 MPa. Unlike the base MBL series, this variant features a screw-adjustable pneumatic cushion at both ends. You can tune the needle to smoothly decelerate the piston near the stroke limits, cutting impact shock and vibration on heavy masses without relying on a fixed rubber bumper. This makes it highly effective for fast cycling where protecting the end covers is critical.
The configuration includes a built-in magnet (-S) for mounting CMSG, DMSG, or EMSG sensor switches to track rod position, and a rigid U flat-end back cover. The riveted rolling-packed aluminum barrel keeps the body compact and lightweight, while the Ø16 carbon-steel rod features a 20 µm hard-chrome plating paired with a heterogeneous two-way grease-retaining piston seal for extended operational life.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X80SU Is Used
Injection Mold Ejection
Provides the 1558 N push force required to knock out dense plastic parts from injection molds, using the adjustable cushion to prevent slamming the rear cover during rapid ejection.
Pallet Diverting
Handles heavy wooden pallets on packaging lines, using the 80 mm stroke to push loads sideways while the U flat-end cover ensures rigid, non-yielding mounting.
PCB Press Fitting
Applies steady pressure to seat electronic connectors onto printed circuit boards, utilizing the -S magnet with a DMSG solid-state sensor to confirm press depth.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X80SU the Right Cylinder?
At 0.5 MPa, this 63 mm bore generates 1558 N push and 1457 N pull. If your application requires less force, the next size down is the 50 mm bore, yielding 981 N push. If you need higher thrust, note that 63 mm is the largest standard bore in this mini-cylinder family, so for higher loads you would need to transition to a different cylinder series entirely. Choose this MBLC version over the fixed-bumper MBL when your cycle speeds are high or the moved mass is heavy enough that a standard bumper would wear out prematurely.
For replacement matching, verify the 63 mm bore, 80 mm stroke, G1/4 port, PT thread, U flat-end back cover, and the -S magnet. Remember that the adjustable air cushion only decelerates the piston near the ends; it is not a brake. If you need to hold position vertically when air is removed or the valve centers, you must add an external rod lock or pilot-operated check valve, as the cylinder will drift otherwise.
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 MBLC63X80SU 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 increases to 2181 N. The maximum theoretical force is 318 kgf at 1.0 MPa.
The MBLC63X80SU features a screw-tunable needle at both ends that traps a pocket of exhaust air to decelerate the piston smoothly before it hits the end cover. You adjust the needle to match your specific load and speed, which is superior to a fixed rubber bumper for heavy or fast-cycling equipment, though it does not lock the load in place.
