About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X100SCA
The AirTAC MBLC40X100SCA is a double-acting aluminum mini cylinder with a 40 mm bore and 100 mm stroke. It generates 628 N of push force at 0.5 MPa and 880 N at 0.7 MPa. A 100 mm stroke is ideal for mid-range linear actuation. Unlike the base MBL, this variant uses a screw-adjustable pneumatic cushion at both ends to decelerate the piston smoothly near stroke extremes, absorbing kinetic energy on faster or heavier moves. The cushion needle is tunable to match your specific load and speed, reducing impact wear on the end covers.
This SKU includes a CA pivot back cover that swings on a pin to accommodate arcing or angular loads, preventing rod binding. The built-in -S magnet allows position detection via AirTAC CMSG (reed) or DMSG and EMSG (solid-state) sensor switches. The riveted rolling-packed aluminum barrel keeps the body compact and lightweight, while the Ø16 carbon-steel rod features 20 µm hard-chrome plating for wear resistance. The heterogeneous two-way grease-retaining piston seal ensures stable friction throughout the 30-800 mm/s speed range.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X100SCA Is Used
Textile Loom Guiding
Drives a 100 mm stroke thread guide arm on a weaving loom. The CA pivot absorbs frame vibration, while the adjustable cushion prevents yarn-snapping jolts at 880 N push force.
Package Sorting Diverter
Pivots a diverter gate on a logistics conveyor. The CA clevis allows the arm to swing naturally, and the tunable cushion softens the 100 mm stroke end-impact during high-speed sorting.
Palletizing Stop Gate
Acts as a pneumatic stop for incoming pallets on a packaging line. The 628 N pull force holds the gate, and the cushion needle is dialed in to stop the rod smoothly without bouncing the load.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X100SCA the Right Cylinder?
At 0.5 MPa, this 40 mm bore delivers 628 N push and 528 N pull. If your payload is lighter, step down to the 32 mm bore (402 N push @0.5 MPa) to save space; if you need more force, step up to the 50 mm bore (981 N push @0.5 MPa). Choose the MBLC over the fixed-bumper MBL when cycle speeds are high or the moved mass is heavy enough to cause jarring impacts. Note that the adjustable air cushion only decelerates the piston near the ends; it does not lock the rod. If you need to hold position without live air pressure, install an external rod lock or pilot-operated check valve.
This configuration uses a PT tapered port thread, an M12x1.25 rod-end thread, and a CA clevis back cover. The CA pivot is essential for applications involving side-arcing motions, but if your load moves purely linearly, the rigid U flat-end cover is a better fit. The -S magnet supports CMSG, DMSG, and EMSG sensors; without the S code, the cylinder cannot accept a switch.

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 MBLC40X100SCA FAQ
At 0.5 MPa, it provides 628 N push and 528 N pull. At 0.7 MPa, it provides 880 N push and 739 N pull. The theoretical maximum holding force is 128 kgf at 1.0 MPa. It features a G1/4 port, an M12x1.25 rod-end thread, and a PT tapered port thread form.
The CA back cover acts as a clevis that swings on a pin, accommodating arcing loads to prevent rod side-loading damage. The adjustable air cushion at both ends uses a screw needle to restrict exhaust air, decelerating the piston smoothly near the stroke ends. It reduces impact noise and end-cover wear on fast cycles, but it is not a brake and will not hold the rod position if air pressure is lost.
