About the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X160U
The AirTAC MBL40X160U is a compact double-acting mini round cylinder engineered for tight machine spaces. It features a 40mm bore and a 160mm stroke, delivering a robust 628 N push force at 0.5 MPa. The U suffix indicates a rigid flat-end rear cover, providing a solid fixed mounting footprint for straightforward linear actuation tasks.
Built with a lightweight riveted rolling-packed aluminum barrel, this unit is permanently crimped rather than tie-rod assembled, ensuring a minimal envelope. The carbon steel piston rod features 20 µm hard-chrome plating to resist wear and corrosion, while a heterogeneous two-way piston seal retains grease for extended operational life. Note that this specific SKU lacks a built-in magnet, so it cannot directly host CMSG, DMSG, or EMSG sensor switches for rod position detection.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X160U Is Used
PCB Router Gantry
Drives the Z-axis plunge on a compact PCB depaneling router, using its 628 N thrust to cleanly cut rigid FR4 boards within a narrow machine enclosure.
Carton Flap Folder
Actuates a mechanical arm to tuck minor flaps on small packaging lines, where the 160mm stroke provides the exact reach needed without occupying excessive footprint.
Bottle Diverter Gate
Pivots a sorting guide on a beverage conveyor to route plastic bottles, relying on the rigid U flat-end mount to withstand repeated lateral shifting forces.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X160U the Right Cylinder?
Selecting the MBL40X160U gives you 628 N of push and 528 N of pull at 0.5 MPa. If your application requires less force, stepping down to the 32mm bore yields 402 N push, while moving up to the 50mm bore provides 981 N for heavier payloads. This model utilizes a fixed rubber bumper to soften end-of-stroke impacts rather than an adjustable air cushion; if your 160mm move involves high kinetic energy or fast cycling, consider the MBLC variant for tunable cushioning.
Because this 160mm stroke pushes an unsupported load, the 16mm rod is susceptible to bending under lateral stress—pair it with an external guide rail to prevent premature seal wear. Furthermore, this cylinder will not hold its load if air pressure drops or the valve is centered; integrate an external pilot-operated check valve if position holding is critical. Replacement matching requires a 40mm bore, 160mm stroke, G1/4 port size, PT thread form, U flat-end back cover, and no 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 MBL40X160U FAQ
At 0.5 MPa, this 40mm bore cylinder provides 628 N push and 528 N pull. At 0.7 MPa, push force increases to 880 N, with a theoretical maximum of 128 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
No, this specific SKU does not have the -S suffix, meaning it lacks a built-in magnet and cannot accommodate CMSG, DMSG, or EMSG sensor switches. You would need to order an MBL40X160SU to enable electronic or reed switch position detection.
