About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X80CA
The AirTAC MBLC40X80CA is a double-acting aluminum mini cylinder featuring a 40mm bore and an 80mm stroke. It supplies 628N of push force and 528N of pull force at 0.5MPa, making it well-suited for mid-range actuation tasks. The riveted rolling-packed aluminum barrel keeps the body compact for tight machinery spaces, while the Ø16 carbon-steel rod features 20μm hard-chrome plating to resist wear.
This variant uses a CA pivot back cover that swings on a pin to accommodate arcing or angular loads. Unlike the base MBL series, this model employs a screw-adjustable pneumatic air cushion at both ends to smoothly decelerate the piston near stroke completion, reducing impact stress on faster or heavier moves. Note that this specific SKU lacks a built-in magnet and cannot support a CMSG, DMSG, or EMSG position sensor.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X80CA Is Used
Packaging Flap Folding
Drives a pivoting arm on a case erector, using the 628N push force and CA clevis to smoothly fold heavy cardboard flaps at high speeds without slamming.
Sorter Diverter Arm
Actuates a routing gate on a logistics conveyor, where the 80mm stroke and tunable end-cushioning prevent harsh impacts during rapid package diversion.
Pallet Stopper Gate
Positions a stopping mechanism on a low-profile assembly line, relying on the compact riveted barrel to fit within constrained conveyor frame clearances.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X80CA the Right Cylinder?
If you need less force, the 32mm bore neighbor provides 402N push at 0.5MPa; if your load requires more, the 50mm bore delivers 981N. Choose this MBLC version over the fixed-bumper MBL when your application runs at high cycle speeds or moves a heavier mass that would prematurely wear out a rubber bumper. Remember that the adjustable air cushion only decelerates the piston near the ends—it is not a locking mechanism, so the rod will drift if air pressure is lost or exhausted. For a drop-in replacement, match the 40mm bore, 80mm stroke, G1/4 port, PT thread, CA pivot 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 MBLC40X80CA FAQ
At 0.5MPa, this 40mm bore cylinder provides 628N of push force and 528N of pull force. At 0.7MPa, the push force increases to 880N. The maximum theoretical force is 128kgf at 1.0MPa.
The CA back cover is a clevis joint that allows the cylinder to swing on a pin, which is necessary when the rod follows an arcing path. The adjustable air cushion at both ends uses a needle valve to trap exhaust air, smoothly decelerating the piston near the 80mm stroke ends to protect the end covers from impact damage.
