About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X80SCA
The AirTAC MBLC40X80SCA is a double-acting aluminum mini cylinder featuring a 40mm bore and 80mm stroke, delivering 628 N of push force and 528 N of pull force at 0.5 MPa. It uses a G1/4 port and a Ø16 mm hard-chrome carbon-steel rod with an M12x1.25 end thread. This size hits a sweet spot for mid-range actuation, while the 80mm travel suits short, rapid positioning tasks.
Unlike the base MBL with its fixed rubber bumper, this MBLC variant utilizes a screw-adjustable pneumatic air cushion at both stroke ends. You tune the needle valve to smoothly decelerate the piston, absorbing kinetic energy to reduce end-cover impact and vibration on heavier loads. The riveted rolling-packed aluminum barrel keeps the body compact for tight machine cells, and the built-in -S magnet enables position detection via AirTAC CMSG (reed) or DMSG/EMSG (electronic) sensor switches.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X80SCA Is Used
Packaging Flap Folding
Drives a 80mm stroke folding arm on a carton erector, using the CA pivot to accommodate the arc of the linkage while the air cushion prevents harsh slamming at 600 mm/s.
Bottle Diverting Gate
Actuates a routing gate on a beverage line, where the 628 N push force at 0.5 MPa easily deflects filled containers and the magnet confirms gate position via a DMSG switch.
PCB Test Socket Press
Applies downward clamping force for electrical testing, relying on the tunable cushion to softly seat the probe head without damaging delicate circuit boards.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X80SCA the Right Cylinder?
Select this 40mm bore when an application requires roughly 628 N of push force at 0.5 MPa. If your load is lighter, stepping down to the 32mm bore yields 402 N of push force; if you need more power, stepping up to the 50mm bore provides 981 N. Choose this MBLC cushioned version over the standard MBL bumper type when cycling faster or moving heavier masses that would prematurely wear a fixed rubber stop. The CA pivot back cover is specifically designed to swing on a pin, making it ideal for arcing or angular loads where a rigid U flat-end cover would bind.
For exact replacement matching, verify the 40mm bore, 80mm stroke, G1/4 port, PT thread form, CA pivot back cover, and the -S magnet. Note that while the adjustable cushion decelerates the rod near the ends, it does not function as a lock; the cylinder will drift if air pressure is lost or the valve centers.

- ✓ 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 MBLC40X80SCA FAQ
At 0.5 MPa, this 40mm bore cylinder outputs 628 N push and 528 N pull force. At 0.7 MPa, push increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa. It features a Ø16 mm carbon-steel rod with an M12x1.25 end thread.
The MBLC uses a screw-adjustable pneumatic air cushion at both ends instead of a fixed rubber bumper. By turning the needle valve, you regulate exhaust flow to smoothly decelerate the piston near the stroke ends, cutting impact noise and vibration on fast or heavy moves. It only decelerates and does not lock the rod in place.
