About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X75U
The AirTAC MBLC40X75U is a compact double-acting aluminum mini cylinder engineered with a screw-adjustable pneumatic cushion at both ends. Delivering 628 N of push force and 528 N of pull force at 0.5 MPa, this 40 mm bore, 75 mm stroke unit is built for fast cycling where fixed rubber bumpers would fail. The riveted rolling-packed aluminum barrel keeps the body light and sealed for tight machinery spaces.
This SKU features a U flat-end back cover for rigid mounting and a Ø16 mm hard-chrome carbon-steel rod (M12x1.25 thread) driven by a heterogeneous two-way grease-retaining piston seal. Because this specific configuration lacks the -S magnet suffix, it cannot accept CMSG, DMSG, or EMSG position sensors. The integrated needle valves allow you to tune the end-of-stroke deceleration, absorbing kinetic energy to protect the end covers on heavier loads without acting as a mechanical lock.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X75U Is Used
PCB Router Gantry
Drives a high-speed Z-axis routing head on a PCB depaneling machine, using the tuned air cushion to halt the 75 mm stroke smoothly without jarring the spindle bearings.
Carton Flap Folder
Actuates a folding arm on a packaging line, leveraging 628 N of push force at 0.5 MPa to tuck heavy cardboard flaps while the cushion prevents end-cover slam during rapid cycling.
Bottle Divert Gate
Pivots a diverter gate on a beverage conveyor, relying on the rigid U flat-end rear mount and adjustable end-deceleration to handle frequent direction changes without vibration.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X75U the Right Cylinder?
Select this 40 mm bore when your application requires 628 N of push force at 0.5 MPa but you want to avoid the bulk of a 50 mm cylinder (which provides 981 N). If your load is lighter, stepping down to a 32 mm bore yields 402 N of push force in a more compact footprint. Choose this MBLC variant over the base MBL specifically when operating speeds exceed what a fixed rubber bumper can absorb, or when moving heavier masses that would prematurely wear the end covers.
For replacement, verify the 75 mm stroke, G1/4 port, PT thread form, U flat-end back cover, and the absence of a magnet. Note that a plain double-acting cylinder does not hold position if air pressure drops or the valve centers; the adjustable air cushion only decelerates the piston near the stroke ends and is not a braking or load-locking device.
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 MBLC40X75U FAQ
This 40 mm bore cylinder uses a G1/4 port and a Ø16 mm rod. At 0.5 MPa it generates 628 N of push force and 528 N of pull force. At 0.7 MPa, push increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa.
No, this specific SKU lacks the built-in magnet (denoted by -S) and therefore cannot accept AirTAC CMSG, DMSG, or EMSG sensor switches. You would need to specify a model with the S suffix, such as the MBLC40X75SU, to enable electronic or reed switch position detection.
