About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X80SU
The AirTAC MBLC40X80SU is a double-acting, single-rod aluminum mini cylinder engineered for compact setups needing controlled end-of-stroke deceleration. It generates 628 N of push force and 528 N of pull force at 0.5 MPa. The 80 mm stroke is optimal for short-travel clamping or ejection tasks where space is restricted but impact mitigation is required.
Unlike the fixed rubber bumper of the base MBL, this MBLC variant features a screw-adjustable pneumatic air cushion at both ends. You tune the needle to match your load and speed, smoothly decelerating the piston to protect the end covers on fast, heavy, or high-frequency cycles. The riveted rolling-packed aluminum barrel keeps the body light and compact, while the 20 µm hard-chrome plating on the carbon-steel rod resists wear and corrosion.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X80SU Is Used
Injection Mold Ejection
Provides 628 N of push at 0.5 MPa to eject plastic parts from molds, using the 80 mm stroke and adjustable cushion to prevent harsh impacts on high-speed cycling presses.
Bottling Line Diverter
Diverts containers on a 30-800 mm/s packaging line, where the tunable air cushion smoothly slows the 16 mm rod to protect guide rails and reduce mechanical noise.
PCB Stacking Stopper
Acts as a rigid stopper for electronics assembly, using the U flat-end cover and position-sensing magnet to verify stack height without bouncing delicate components.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X80SU the Right Cylinder?
If your application requires less force, step down to the 32 mm bore (402 N push at 0.5 MPa); if you need more power, step up to the 50 mm bore (981 N push at 0.5 MPa). Choose this MBLC over the base MBL when your cycle speeds exceed what a fixed rubber bumper can absorb without causing damaging shock or vibration.
This SKU includes the U flat-end back cover for rigid mounting and a built-in magnet (-S) for CMSG reed or DMSG/EMSG electronic sensor switches. It uses a G1/4 port and M12x1.25 rod thread. Note that the air cushion only decelerates the piston near the stroke ends; it is not a brake and will not hold the load 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 MBLC40X80SU FAQ
At 0.5 MPa, it provides 628 N push and 528 N pull. At 0.7 MPa, push increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa with a speed range of 30-800 mm/s.
The cushion is a screw-tunable pneumatic needle at both ends that traps exhaust air to decelerate the piston near the stroke end. You adjust it to match your specific load and speed, which reduces end-cover impact, noise, and vibration. It is strictly a deceleration device, not a load lock or brake.
