About the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X160SU
The AirTAC MBL40X160SU is a double-acting aluminum mini round cylinder engineered for tight machine spaces. It features a 40mm bore and 160mm stroke, generating 628 N push and 528 N pull force at 0.5 MPa. The riveted rolling-packed barrel crimps the front and rear covers directly to the tube, creating an exceptionally light, compact body that is not designed to be disassembled like a 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 internal two-way piston seal retains grease for long life, while the carbon steel rod with 20 um hard-chrome plating resists wear and corrosion. It uses a G1/4 port and a Ø16 mm rod with an M12x1.25 thread end.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X160SU Is Used
Packaging Conveyor Diverter
Provides 628 N push force at 0.5 MPa to reliably actuate routing gates on high-speed packaging lines handling mixed product sizes.
PCB Test Socket Clamping
Uses the built-in magnet and 160mm stroke to position electronic test fixtures over PCB arrays, confirming seat pressure via a DMSG solid-state sensor.
Carton Flap Folder
Drives mechanical folding arms on case sealing machinery, where the compact riveted aluminum barrel fits neatly within tight conveyor frame clearances.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X160SU the Right Cylinder?
If you need less force, step down to the 32mm bore (402 N push @0.5 MPa); if you need more, step up to the 50mm bore (981 N push @0.5 MPa). This model uses a fixed rubber bumper to soften end-of-stroke impact; choose the MBLC variant if your application requires adjustable air cushioning for heavier moving masses. The -S magnet on this unit supports AirTAC CMSG (reed) and DMSG/EMSG (electronic) sensor switches.
A standard MBL does not hold its load when air pressure is lost or the valve is centered, as the rod will drift or drop. The rubber bumper only absorbs end-stroke impact and is not a locking brake. For any load-holding requirement, add an external rod lock or a pilot-operated check valve. At a 160mm stroke, the unsupported Ø16 rod has limited side-load tolerance; use an external guide or an MBLD double-rod cylinder to prevent bending under lateral loads.
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 MBL40X160SU FAQ
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At 0.7 MPa, the push force is 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa.
No, the base MBL40X160SU uses a fixed rubber bumper to absorb end-of-stroke impact. It does not have an adjustable cushion screw. If you need adjustable air cushioning for faster cycling or heavier loads, select the MBLC variant.
