About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X500SU
The AirTAC MBLC50X500SU is a double-acting aluminum mini cylinder featuring a 50mm bore and a 500mm stroke, delivering 981N of push force at 0.5MPa. The built-in magnet (-S) enables precise rod position detection using AirTAC CMSG, DMSG, or EMSG sensor switches. A rigid U flat-end back cover provides a straightforward, fixed rear mounting interface. This model utilizes a G1/4 port and a Ø16 carbon-steel rod with 20µm hard-chrome plating to resist wear and corrosion.
This unit relies on a screw-adjustable pneumatic air cushion at both stroke ends rather than a fixed rubber bumper. By tuning the needle valves, you decelerate the piston smoothly near the end limits, absorbing kinetic energy to protect the end covers during fast, heavy 500mm traverses. The riveted rolling-packed aluminum barrel keeps the body compact and lightweight for tight assembly spaces. Note that the air cushion only slows the piston near the ends; it is not a brake and does not hold the load if air pressure is lost.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X500SU Is Used
CNC Lathe Bar Feeder
Pushes raw bar stock through a spindle over the full 500mm travel; the adjustable air cushion prevents harsh end-impact during rapid loading, while the magnet tracks stock position.
Packaging Line Pusher
Transfers heavy cartons between conveyors where 981N of push force is needed; the cushioning decelerates the 50mm piston smoothly to avoid jarring the packaged goods at stroke end.
Warehouse Shuttle Retrieval
Extracts totes from deep storage racks using the full 500mm stroke, relying on the tunable end-cushion to stop the load gently without bouncing the shuttle frame.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X500SU the Right Cylinder?
Stepping down, the 40mm bore neighbor offers 628N push at 0.5MPa, whereas stepping up to the 63mm bore yields 1558N push at 0.5MPa. Choose this MBLC50X500SU over the base MBL when your cycle speeds or moving masses are too high for a fixed rubber bumper to absorb safely. At 500mm of travel, the small 16mm rod is highly susceptible to bending under side loads; you must use an external linear guide, a CA or SDB pivot mount, or switch to an MBLD double-rod cylinder to prevent premature seal failure. For replacements, match the 50mm bore, 500mm stroke, G1/4 port, PT thread, U back cover, and the -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 MBLC50X500SU FAQ
At 0.5MPa it provides 981N push and 881N pull force. At 0.7MPa, push increases to 1374N. The maximum theoretical force is 200kgf at 1.0MPa. The 500mm stroke is the maximum standard length available for this 50mm bore; longer travels up to 800mm require a special made-to-order request.
The cushion is a screw-tunable needle valve at both ends that traps exhaust air to decelerate the piston smoothly near the stroke limits, preventing end-cover impact on heavy loads. The -S denotes a built-in magnet for electronic position feedback, compatible with AirTAC CMSG (reed), DMSG, and EMSG (solid-state) sensor switches.
