About the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X200SU
The AirTAC MBL40X200SU is a double-acting aluminum mini round cylinder engineered for tight machine spaces where a larger profile body cannot fit. It uses a 40mm bore and a 200mm stroke to generate 628N of push force and 528N of pull force at 0.5 MPa. The riveted rolling-packed barrel design permanently crimps the front and rear covers to the tube, creating a lightweight, compact body that is not designed to be disassembled like a traditional tie-rod cylinder.
This specific SKU includes a U flat-end back cover for rigid rear mounting and a built-in magnet (-S) for position detection. The carbon-steel piston rod features a 20um hard-chrome plating for wear and corrosion resistance, paired with a heterogeneous two-way piston seal that retains grease for a long service life. It uses a G1/4 port and a fixed rubber bumper to soften end-of-stroke impact.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X200SU Is Used
CNC Lathe Bar Feeder
Pushes raw bar stock through the spindle guide tube. The 628N push force at 0.5 MPa easily overcomes feed tube friction, while the -S magnet confirms rod retraction to the home position.
Palletizer Strapping Tool
Actuates the strapping head tensioner on an end-of-line packaging machine. The 200mm stroke provides the exact travel needed to cycle the strapping clamp, and the U flat-end cover mounts rigidly to the machine subplate.
PCB Router Degating
Separates routed printed circuit board panels from their breakout tabs. The compact aluminum body fits between tight pick-and-place gantry rails, and the DMSG solid-state electronic sensor tracks the 16mm chrome rod extension.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X200SU the Right Cylinder?
If you need less force, step down to the 32mm bore (402N push at 0.5 MPa); if you need more power, step up to the 50mm bore (981N push at 0.5 MPa). Because this is a 200mm stroke, the 16mm rod has limited side-load tolerance; for heavy offset loads, use an external guide rail, a CA pivot back cover, or the MBLD double-rod anti-rotation type. The fixed rubber bumper softens impact but is not an adjustable air cushion (choose MBLC for that). A plain MBL does not hold its position if air pressure is lost or the valve is centered; use an external rod lock or pilot-operated check valve for fail-safe load holding. Replacement match: 40mm bore, 200mm stroke, G1/4 port, PT thread, U flat-end back cover, -S magnet.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 MBL Aluminum Alloy Mini Cylinder MBL40X200SU FAQ
At 0.5 MPa, the push force is 628N and the pull force is 528N. At 0.7 MPa, the push force increases to 880N. The maximum theoretical force is 128 kgf at 1.0 MPa. The double-acting operating speed range is 30-800 mm/s.
No, the base MBL40X200SU uses a fixed rubber bumper to soften the end-of-stroke impact; it does not have an adjustable cushion screw. If your application requires adjustable air cushioning for heavier or faster moving loads, you should select the MBLC variant instead.
