About the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X100SU
The AirTAC MBL40X100SU is a double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers 628 N of push force and 528 N of pull force at 0.5 MPa across a 100 mm stroke. The riveted rolling-packed barrel permanently crimps the front and rear covers to the tube, yielding a lightweight, compact footprint that is not designed to be disassembled or rebuilt like a heavy tie-rod cylinder.
This specific SKU includes a U flat-end back cover for rigid fixed mounting and a built-in magnet (-S) for non-contact position sensing. The internal heterogeneous two-way piston seal actively retains grease to maximize service life, while the carbon steel piston rod features 20 μm hard-chrome plating for high wear and corrosion resistance. The base MBL relies on a fixed rubber bumper to soften end-of-stroke impacts rather than an adjustable air cushion.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X100SU Is Used
Injection Mold Ejection
Provides 628 N of push force at 0.5 MPa to positively eject small plastic parts from tight mold cavities within a 100 mm travel envelope.
Packaging Diverter
Uses its 100 mm stroke and rigid U flat-end mount to rapidly push light cartons between adjacent conveyor lanes without requiring large framework clearances.
PCB Test Station
Lowers an electronic test probe into position with its magnet-equipped body, allowing a DMSG solid-state sensor to trigger the next board indexing step.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X100SU the Right Cylinder?
If you need slightly less force, step down to the 32 mm bore (402 N push @0.5 MPa); for heavier cycles, step up to the 50 mm bore (981 N push @0.5 MPa). Choose the MBLC variant if your cycle speeds require an adjustable air cushion to decelerate heavier loads. The built-in magnet supports CMSG reed and DMSG or EMSG electronic sensor switches for end-position confirmation. A standard MBL cannot hold a load if air pressure drops or the valve is centered—the rod will drift—so fit an external rod lock or pilot-operated check valve for fail-safe positioning. At a 100 mm stroke, side-load bending is minimal, but always keep the load axially aligned to protect the 16 mm rod bearing.
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 MBL40X100SU FAQ
This 40 mm bore cylinder uses a G1/4 port and a Ø16 mm rod. It generates 628 N push and 528 N pull at 0.5 MPa, 880 N push at 0.7 MPa, and a maximum theoretical force of 128 kgf at 1.0 MPa.
No, the base MBL uses a fixed rubber bumper to absorb end-of-stroke impact, not an adjustable air cushion (you would need the MBLC variant for that). It also does not hold position under loss of air pressure; use an external rod lock for fail-safe load holding.
