About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X80U
The AirTAC MBLC40X80U is a double-acting aluminum mini cylinder with an 80 mm stroke and a 40 mm bore. It generates 628 N of push force and 528 N of pull force at 0.5 MPa, scaling to 880 N push at 0.7 MPa. The U suffix denotes a rigid flat-end back cover for straightforward inline mounting. Because this specific SKU lacks the -S magnet code, it cannot accept a CMSG, DMSG, or EMSG position sensor switch.
This model features a screw-adjustable pneumatic air cushion at both stroke ends. You tune the needle to smoothly decelerate the piston near the end caps, absorbing impact on faster or heavier moves better than a fixed rubber bumper. The riveted rolling-packed aluminum barrel keeps the body compact for tight spaces, while the 20 µm hard-chrome plating on the carbon-steel rod defends against wear and scoring.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X80U Is Used
Injection Mold Extraction
Provides 628 N of push to eject plastic parts from molds, using the adjustable cushion to halt the 80 mm stroke gently without cracking fragile components.
Pallet Diverter Arm
Swings lightweight routing gates on packaging lines, relying on the tunable end-cushion to prevent end-cover impact during continuous high-frequency routing.
Carton Flap Folder
Folds corrugated cardboard flaps at speed, where the 528 N pull force retracts the arm cleanly while the pneumatic cushion dampens the return shock.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X80U the Right Cylinder?
At 0.5 MPa, this 40 mm bore yields 628 N push and 528 N pull. If you need less force, the 32 mm bore neighbor provides 402 N push; if your load is heavier, step up to the 50 mm bore for 981 N push. Choose this MBLC over the base MBL when your cycle speeds are high and the fixed bumper cannot adequately absorb the kinetic energy. Keep in mind the air cushion only decelerates near the ends; it is not a lock, so the rod will drift if air pressure is lost or the valve centers. The replacement match is bore 40, stroke 80, G1/4 port, M12x1.25 rod thread, PT thread form, U flat-end 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 MBLC40X80U FAQ
At 0.5 MPa, this 40 mm bore cylinder delivers 628 N of push force and 528 N of pull force. At 0.7 MPa, the push force increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa.
No. This specific SKU lacks the -S suffix, meaning it is manufactured without a built-in magnet. To use CMSG reed or DMSG/EMSG electronic solid-state switches for rod position detection, you must select the MBLC40X80SU variant instead.
