About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X100U
The AirTAC MBLC40X100U is a compact double-acting aluminum mini cylinder engineered to deliver 628 N of push force and 528 N of pull force at 0.5 MPa. Driven by a Ø16 mm carbon-steel rod with a 20 µm hard-chrome plating, it utilizes a G1/4 port and an M12x1.25 rod-end thread. The 100 mm stroke is optimal for mid-length transfers and ejection tasks where a balanced footprint is required.
Unlike the base MBL which relies on a fixed rubber bumper, this MBLC variant features a screw-adjustable pneumatic air cushion at both ends. Tuning the needle valve allows you to smoothly decelerate the piston near stroke extremes, minimizing end-cover impact and vibration on heavier loads. The body uses a riveted rolling-packed aluminum barrel for a lightweight, space-saving profile, while the heterogeneous two-way grease-retaining piston seal ensures consistent lubrication over the 30-800 mm/s speed range.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X100U Is Used
PCB Router Ejection
Deploys the 100 mm stroke to push singulated circuit boards out of a routing fixture, using the tuned air cushion to prevent the 628 N thrust from cracking panel edges at high speed.
Carton Flap Folding
Drives a mechanical arm to tuck packaging flaps on a filling line, relying on the adjustable end-cushioning to absorb the 528 N pull force smoothly without jarring the conveyor frame.
Bottle Sorting Diverter
Actuates a diverter gate to route glass containers, where the 40 mm bore provides enough power to overcome friction and the cushion needle prevents shock loads from loosening the bracketry.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X100U the Right Cylinder?
Select this 40 mm bore when your application requires roughly 628 N of push force at 0.5 MPa. If you need less force, stepping down to the 32 mm bore yields 402 N push, while stepping up to the 50 mm bore provides 981 N push for heavier payloads. Choose this MBLC model over the standard MBL when cycle speeds are high or the moved mass is substantial enough that a fixed rubber bumper would wear prematurely.
This specific SKU includes a U flat-end back cover for rigid mounting and uses PT threaded ports. Because it lacks the -S suffix, a built-in magnet is not fitted, meaning it cannot support CMSG, DMSG, or EMSG position sensors. Note that the adjustable air cushion only decelerates the piston near the ends; it is not a brake, so the rod will drift if air pressure is lost.
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 MBLC40X100U FAQ
This 40 mm bore cylinder uses a G1/4 port and generates 628 N push and 528 N pull at 0.5 MPa. At 0.7 MPa, it outputs 880 N push and 739 N pull. The maximum theoretical force is 128 kgf at 1.0 MPa.
No, this specific SKU lacks the -S suffix, meaning no internal magnet is installed and it cannot accept CMSG, DMSG, or EMSG sensor switches. You would need the MBLC40X100SU variant for reed or electronic solid-state position detection.
