About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X175SU
The AirTAC MBLC40X175SU is a double-acting aluminum mini cylinder engineered to deliver 628 N of push force and 528 N of pull force at 0.5 MPa. A 175 mm stroke makes it well-suited for mid-range linear actuation where stopping heavier loads smoothly is critical. Unlike the base MBL series which relies on a fixed rubber bumper, this MBLC variant features a screw-adjustable pneumatic air cushion at both ends. Tuning the cushion needle lets you decelerate the piston near the stroke extremes, effectively absorbing kinetic energy to reduce end-cover impact, mechanical noise, and vibration.
Built around a riveted rolling-packed aluminum barrel for a lightweight yet compact footprint, the unit houses a Ø16 mm carbon-steel rod plated with 20 µm hard chrome to resist corrosion and scoring. The internal heterogeneous two-way grease-retaining piston seal maintains optimal lubrication over high-speed cycles ranging from 30 to 800 mm/s. This specific configuration includes a U flat-end back cover for rigid rear mounting and a built-in magnet (-S) for position detection. The G1/4 port and M12x1.25 rod-end thread are standard for this 40 mm bore size.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X175SU Is Used
PCB Router Z-Axis
Drives a 175 mm vertical plunge on a PCB depaneling router, using the adjustable cushion to brake the 628 N cutting head smoothly before the end of travel, preventing vibration marks on the board.
Bottle Divert Arm
Actuates a sweeping diverter arm on a packaging line, moving heavier glass bottles laterally while the cushioned ends absorb the kinetic energy of the rapid 175 mm shift without jarring the conveyor frame.
Server Chassis Ejector
Pushes dense server chassis out of an assembly fixture, using the -S magnet to trigger a DMSG electronic sensor that confirms the full 175 mm ejection stroke before the robotic gripper engages.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X175SU the Right Cylinder?
Selecting the MBLC40X175SU is ideal when your application requires the 628 N push force at 0.5 MPa alongside precise end-of-stroke deceleration. If your payload is lighter, stepping down to the 32 mm bore yields 402 N of push force, whereas moving heavier fixtures warrants the 50 mm bore which provides 981 N. Choose this adjustable air cushion model over the fixed-bumper MBL when cycling rapidly with substantial mass, as the tunable needle prevents harsh mechanical crashes. Keep in mind that the air cushion only decelerates the piston near the ends; it is not a locking mechanism. If the air supply is lost or the valve centers, the rod will drift, so an external rod lock or pilot-operated check valve is required for strict position holding.
At a 175 mm stroke, the 16 mm rod is susceptible to side-loading and bending if the load is not perfectly axial. To mitigate premature seal wear, utilize an external guide rail, select a pivot mounting bracket, or switch to an MBLD double-rod cylinder. This SKU is configured with a U flat-end back cover for rigid mounting, PT threaded ports, and a built-in magnet (-S) for use with AirTAC 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 MBLC40X175SU 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, the push increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa. It uses a G1/4 port, a Ø16 mm rod with an M12x1.25 thread, and operates at speeds between 30 and 800 mm/s.
The MBLC40X175SU features a screw-tunable pneumatic cushion at both stroke ends. By turning the needle valve, you trap a pocket of exhaust air that decelerates the piston before it hits the end cover. This is essential for high-speed or heavy loads to reduce impact noise, replacing the fixed rubber bumper found on the standard MBL series. It only decelerates and does not lock the rod in place.
