About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X160SU
The AirTAC MBLC40X160SU is a double-acting aluminum mini cylinder engineered for compact actuation. It delivers 628 N of push force and 528 N of pull force at 0.5 MPa, utilizing a 40 mm bore and 160 mm stroke. This specific configuration includes a U-type flat-end back cover for rigid rear mounting and a built-in magnet (-S) for position sensing.
Unlike the base MBL series which relies on a fixed rubber bumper, this MBLC variant features a screw-adjustable pneumatic air cushion at both stroke ends. This allows you to precisely tune the end-of-stroke deceleration to match your load and speed, effectively absorbing kinetic energy to prevent end-cover damage on high-frequency lines. The riveted rolling-packed aluminum barrel keeps the overall footprint tight for tight machinery, while the 20 µm hard-chrome plated carbon-steel rod resists wear against the heterogeneous two-way grease-retaining piston seal.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X160SU Is Used
PCB Stacking Ejector
Ejecting populated printed circuit boards from an SMT conveyor line, where the 628 N push force reliably clears the workpiece and the tunable air cushion prevents harsh snap-back at 160 mm stroke.
Carton Flap Folder
Folding minor flaps on a continuous carton packaging machine, utilizing the 160 mm stroke to clear the product path while the cushioned ends absorb the repetitive high-frequency impacts.
Bottle Divert Gate
Driving a diverter gate on a beverage filling conveyor, where the U flat-end back cover provides rigid rear mounting and the integrated magnet confirms gate position via a DMSG electronic sensor.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X160SU the Right Cylinder?
Selecting this 40 mm bore makes sense when your application requires roughly 628 N of push force at 0.5 MPa. If your load is lighter, stepping down to the 32 mm bore yields 402 N of push force, saving valuable space. For heavier dynamics, the 50 mm bore provides 981 N of push force. The 160 mm stroke is ideal for moderate travel distances, but at this length the 16 mm rod has limited tolerance for side loads; using an external guide rail prevents rod bending and premature seal failure.
Choose the MBLC over the standard MBL when your cycle speeds are high or the moved mass is significant enough that a fixed rubber bumper would fail to adequately absorb the impact. Remember that the adjustable air cushion only decelerates the piston near the ends and does not lock the rod; if you need the cylinder to hold position during a loss of air pressure, you must integrate an external pilot-operated check valve or a dedicated rod lock. This exact SKU features a PT tapered port thread, an M12x1.25 rod-end thread, a rigid U flat-end back cover, and an integrated magnet for CMSG, DMSG, or EMSG sensor switches.

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 MBLC40X160SU FAQ
The 40 mm bore generates 628 N push and 528 N pull at 0.5 MPa, increasing to 880 N push at 0.7 MPa, with a theoretical maximum of 128 kgf at 1.0 MPa. It uses a G1/4 port, a 16 mm rod, and an M12x1.25 rod-end thread.
The cushion is a screw-tunable needle at both ends that traps exhaust air to decelerate the piston smoothly near the stroke limits, which is critical for protecting the end covers on fast moves. The built-in -S magnet allows CMSG, DMSG, and EMSG sensor switches to detect position, but it does not lock the rod; the cylinder will drift if air pressure is lost.
