About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X10SCA
The AirTAC MBLC40X10SCA is a compact double-acting aluminum mini cylinder engineered for short-stroke arcing operations. It delivers a push force of 628 N and a pull force of 528 N at 0.5 MPa, making it highly effective for robust pivoting mechanisms. Unlike the base MBL series which relies on a fixed rubber bumper, this MBLC variant incorporates a screw-adjustable pneumatic air cushion at both ends. This allows you to precisely tune the end-of-stroke deceleration, smoothly slowing the piston to cut impact shock, vibration, and noise during rapid or heavy moves.
This specific configuration includes a built-in magnet (-S) for compatibility with AirTAC CMSG, DMSG, and EMSG sensor switches to track rod position. It uses a CA pivot/clevis back cover that swings on a pin to accommodate angular arcing loads. The riveted rolling-packed aluminum barrel keeps the body light and compact for tight spaces, while the Ø16 mm carbon-steel rod features 20 µm hard-chrome plating to resist wear. The heterogeneous two-way grease-retaining piston seal ensures consistent lubrication over its 30-800 mm/s speed range.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X10SCA Is Used
Stamping Press Ejection
Delivers 628 N of push at 0.5 MPa to eject small stamped metal parts from a die, using the 10 mm stroke for a fast, short kick that protects the tooling.
Pivoting Diverter Gate
Uses the CA clevis back cover to swing a lightweight sorting flap on a packaging conveyor, handling angular motion without binding the rod.
PCB Test Clamp
Applies a controlled 528 N pull force to hold a circuit board fixture in place, relying on the adjustable air cushion to soften the 10 mm retraction stop.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X10SCA the Right Cylinder?
To size this actuator accurately, consider stepping down to the 32 mm bore if your application requires less force—it yields 402 N of push and 346 N of pull at 0.5 MPa. Conversely, if your pivoting load demands more power, stepping up to the 50 mm bore provides 981 N of push and 881 N of pull at 0.5 MPa. The 10 mm stroke here is ideal for very short rotational arcs. Choose this MBLC cushioned version over the fixed-bumper MBL when your mechanism cycles quickly or moves a heavier mass that would otherwise violently strike the end covers. Remember that the adjustable air cushion only decelerates the piston near the stroke ends; it is not a mechanical lock. If you need to hold the load in place without continuous live air pressure, you must add an external rod lock or a pilot-operated check valve. Replacement matches: 40 mm bore, 10 mm stroke, G1/4 port, M12x1.25 rod thread, PT port thread, CA pivot back cover, and -S magnet.

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 MBLC40X10SCA FAQ
At 0.5 MPa, this 40 mm bore cylinder provides 628 N of push force and 528 N of pull force. At 0.7 MPa, it delivers 880 N of push. The maximum theoretical force is 128 kgf at 1.0 MPa.
The screw-tunable pneumatic cushion at both ends decelerates the piston smoothly near the 10 mm stroke limits, reducing impact on fast cycles. The CA pivot back cover swings on a pin to absorb angular arcing loads, preventing rod side-load damage.
